Integrating hands-on practical and reflective feedback in teaching dental materials science to undergraduate dental students

INTRODUCTION

This study aimed to develop a module that incorporates hands-on and reflective feedback in teaching dental materials science and subsequently analyse undergraduate dental students' learning experiences with the module.

MATERIALS AND METHODS

The module was developed based on the ADDIE (Analyse, Design, Develop, Implement, Evaluate) model. First, a need analysis was conducted, followed by designing the module to address the needs. Next, the module sought experts' feedback and was piloted. The revised module was implemented among all second-year undergraduate dental students. Finally, a validated questionnaire (5-point Likert scale items and open-ended questions) was used to evaluate students' learning experiences. The questionnaire Likert scale items were analysed descriptively, whereas open-ended responses were analysed using content analysis.

RESULTS

In the analysis phase, a slight misalignment in cognitive competency levels was observed, alongside a need for the inclusion of more hands-on activities. In the design phase, learning objectives and resources were listed. Subsequently, a module consisting of four teaching sessions (3 h each) was developed, and the pilot test showed favourable feedback. The module was then implemented in small groups of 10-12 students. In the evaluation phase, 72 students (97% response rate) completed the questionnaire. The majority of students agreed with all items, with mean scores ranging from 4.53 to 4.72. Open-ended responses highlighted that hands-on activities and reflective feedback sessions were useful.

CONCLUSION

Students demonstrated positive learning experiences after participating in the module, advocating for dental educators to consider more hands-on activities and reflective feedback sessions in teaching dental materials science.

Dental students' perceptions of instructor storytelling for clinical learning: A qualitative description study

OBJECTIVE

Storytelling has been infrequently used in dental education to link clinical knowledge and practice. Our study aimed to explore dental students' views of instructor storytelling with an emphasis on clinical reasoning within a case-based oral pathology seminar.

METHODS

Qualitative description guided the study design. Participants were third- and fourth-year undergraduate dental students who participated in the seminar. Data were collected through semi-structured, one-on-one interviews. Data analysis was approached using inductive, manifest thematic analysis. Verification strategies were employed to ensure methodological rigor throughout the analysis.

RESULTS

In total, 21 students participated in the study ranging in age from 22 to 29 years. Three interrelated themes were identified, which were related to storytelling authenticity, benefits, and recommendations for improvement. Specifically, students reported that instructor stories effectively conveyed genuine cases and clinical reasoning; were beneficial in terms of engagement, awareness, knowledge acquisition, and skill development; and needed to be educationally and clinically relevant to bridge the knowledge-practice gap.

CONCLUSIONS

Instructor storytelling was regarded by dental students as both positive and beneficial. Research is needed to further demonstrate the effectiveness of instructor storytelling in fostering clinical learning and reasoning using indirect and direct outcome measures.

A new attempt of applying hybrid team-based and case-based learning approach in dental materials science: Does it work?

INTRODUCTION

Limited studies have been conducted on the use of a hybrid team-based learning (TBL) and case-based learning (CBL) approach in dental education. The present study aims to evaluate students' experience of the hybrid TBL-CBL in learning dental materials science subjects.

METHODS

All second-year undergraduate Bachelor of Dental Surgery (BDS) students were invited to participate in a TBL-CBL session. These participants were randomly allocated to six different groups of 10-12 students, and the session was conducted by one lecturer as the facilitator. A 23-item questionnaire assessing four domains (perceptions of effectiveness, teacher, team interaction and learning environment) was administered at the end of the TBL-CBL session.

RESULTS

The response rate was 91.9% (n = 68). Mean scores for the questionnaire items ranged from 4.13 to 4.60 suggesting a positive perception among the students towards the hybrid TBL-CBL approach. Regarding the open-response questions, students emphasised that the TBL-CBL session was effective for team interaction and group discussions. However, students wished to have a better venue for future sessions.

CONCLUSION

Positive perceptions of the students encourage future educators to consider the use of TBL-CBL approach in teaching dental materials science and to avoid the reliance on standalone conventional lectures. Future research could consider examining its effects on students' academic achievement as well as the perspectives of teachers regarding its adoption in different dental specialities.

Learning styles and their relationship with preferred teaching methodologies and academic achievement among medical students in teaching medical college, Tamil Nadu

BACKGROUND

Learning styles for medical students have been studied worldwide, and instructors must know and employ the best methods to help students learn. This study evaluates undergraduate medical students' learning styles, preferred teaching methods, and academic examination scores.

MATERIALS AND METHODS

From January to December 2022, this cross-sectional study was performed with medical students at a teaching hospital in Perambalur, Tamil Nadu, India. About 421 individuals were selected using a probability-proportionate size sampling method. A semi-structured pro forma was used to collect the socio-demographic profile, VARK model learning style questionnaire, and teaching method preferences. The data were analyzed using SPSS-21, and the categorical data were represented as frequency and percentage, whereas mean and standard deviation represent quantitative data. The Chi-square test was used to investigate the relationship between academic performance and teaching approaches to the preferred learning style.

RESULTS

Kinesthetic learning was the preferred sensory modality. Nearly 61.8% of medical students were female. The most common preferred learning style among them was (36.8%) kinesthetic, followed by (36.1%) auditory. Most of them received good academic results (64.8%), followed by average (21.9%) results. Most of the students had chosen a demonstration (81.2%), followed by an interactive lecture (77.2%), as their preferred teaching method. There is a significant association of learning style with participant age (p 0.007), year of study (p 0.0001), and preferred teaching methodologies like a demonstration, small group discussion, self-presentation, and laboratory work, which is statistically significant. There is no association between learning style and academic performance.

CONCLUSION

Different teaching approaches, such as demonstration, small-group discussion, self-presentation, and laboratory work, were related to the various learning styles of the students. We also determined that the individuals' preferred learning styles do not affect their academic achievement.

Skill Retention of Light-Curing Technique Using Only Verbal Instructions versus Using an Instructional Video: A 2-Year Follow-Up Study of Dental Students

PURPOSE

To evaluate the retention of light-curing skills among dental students after two years of clinical experience and determine if there are any differences in the skills retention between students who received verbal instructions or those who had received an instructional video. The students' satisfaction with past learning, self-confidence, and general knowledge about light-curing were also evaluated.

METHODS

This study is a 2-year evaluation of previous work. Students had previously been divided into two groups: those who received only verbal instructions, and those who received only an instructional video about the correct light curing technique to use clinically. Each student had light-cured simulated restorations (anterior and posterior) for 10 sec using the Managing Accurate Resin Curing-Patient Simulator (MARC-PS) (BlueLight Analytics, Halifax, Nova Scotia, Canada) and a multiple-emission peak light-emitting-diode (Bluephase N, Ivoclar Vivadent, Schaan, Liechtenstein) curing light. Students then received instructions according to their assigned group and light-cured the simulated cavities again. Two years later, students from both groups light-cured the same simulated cavities. Then, they completed a modified version of the National League of Nursing (NLN) satisfaction and self-confidence questionnaire and answered light-curing knowledge questions. Statistical analysis: The mean radiant exposure values delivered before receiving specific instructions on light curing, immediately after, and two years after instruction for both teaching methods (Friedman test followed by Wilcoxon signed-rank post hoc test), and the difference between both teaching methods was assessed (two-sample Wilcoxon rank-sum test). The satisfaction and self-confidence scores were compared between teaching method groups (Wilcoxon rank-sum test) (p<0.05).

RESULTS

The mean and median irradiance values ranged between 194-1777 and 1223-1302 mW/cm² before instructions, 320-1689 and 1254-1394 mW/cm² immediately after instructions, and 95-1945 and 1260-1331 mW/cm² two years later regardless of the simulated restoration or the teaching method. The mean and median radiant exposure values ranged between 2-23 and 12.5-13.6.4 J/cm² before instructions, 3-28 and 12.8-14.3 mW/cm² immediately after instructions, and 0.7-20 and 12.8-13.6 mW/cm² two years later regardless of the simulated tooth being light cured and the teaching method. Students retained their light-curing skills after two years of clinical experience, with no significant differences between both groups. The instructional video group delivered significantly higher radiant exposure values (p=0.021) when light-curing the anterior tooth than the posterior. Students were satisfied with their past learning and confident in their light-curing skills (p=0.020). There were statistical differences in how well the two groups remembered what they had been taught about light-curing. Only 5.7% of students answered all knowledge questions correctly.

CONCLUSION

Students retained their light-curing skills after two years of clinical experience, with no significant difference between verbal instructions or instructional video teaching methods. However, their knowledge about light curing remained very poor. Nevertheless, the students were satisfied with how they had been taught and had confidence in both teaching methods.

[Constructing of clinical thinking of acupuncture and moxibustion, improving the medical record writing ability of standardized training physicians: teaching experience of the standardized training textbook Acupuncture and Moxibustion for national TCM resident physicians]

To explore the methods of cultivating the clinical thinking ability of acupuncture and moxibustion in the standardized training of resident physicians, so as to improve the medical record writing ability of the regular training physicians. The clinical diagnosis and treatment of acupuncture and moxibustion has its own characteristics and can't copy the syndrome differentiation and treatment mode of TCM internal medicine. In the treatment section, Acupuncture and Moxibustion, a standardized training textbook for national TCM resident physicians, takes clinical cases as the breakthrough point and uses the problem as the guide, guides the training physicians to cultivate acupuncture and moxibustion clinical diagnosis and treatment from three aspects: disease diagnosis, syndrome diagnosis, and treatment ideas, forms a complete understanding of the disease, and improves the standardization, logicality and systematicness of medical record writing through repeated practical training.

The Use of Virtual-Problem-Based Learning during COVID-19 Pandemic Emergency: Veterinary Students' Perception

The COVID-19 global pandemic emergency forced us to replace the "traditional and in presence" clinical, pre-graduating, veterinary medical training with clinical virtual-problem-based learning (v-PBL). This prospective cross-sectional case-control study aimed to evaluate the students' perception of the v-PBLs compared to the traditional veterinary clinical training (t-VCT). The t-VCT consisted of supervised management of clinical cases admitted at the Veterinary Teaching Hospital and in the field. The v-PBL consisted of genuine clinical cases shared by tutors throughout an online platform. A survey was delivered to all the fifth-year students who completed the t-VCT or the v-PBL. The survey was completed by 49% of the students. Overall student satisfaction regarding the training experiences was high in both groups, but it was less in the v-PBL than in the t-VCT group. The students of the v-PBL group perceived that they could not improve their practical clinical skills through online sessions, and they emphasized how it could be employed as support for traditional practical activities. All the students are satisfied with the supervision and considered the training correctly focused on relevant learning objectives and the task clearly explained. Stimulating the integration of knowledge and lifelong learning skills replicating life experiences the v-PBLs represented an attractive curricular alternative for veterinary education.

Heuristic Learning as a Method for Improving Students' Teamwork Skills in Physical Education

Transversal skills are the knowledge, skills, and personal qualities that are currently needed to meet the demands of the working world and everyday life. Schools have the task of equipping students with these skills, working not only on disciplinary goals but also on operational-behavioral goals. In 2018, the European Union adopted new recommendations on eight key competencies for lifelong learning and asked schools to implement new methods to develop these recommendations. To be successful, it is necessary to stimulate students' development of these competences, which are also called soft skills, from the earliest years of the school experience. Physical education (PE) is called upon to make its contribution. In Italy, the two teaching methods used during PE classes are prescriptive teaching and heuristic learning. It is not clear which of the two methods is the most effective in improving soft skills, especially the skills involved in teamwork. The objective of this article was to compare the effects of these two teaching methods on students' teamwork skills during PE classes in primary schools. After verifying the normality of the data, a Student's t-test for dependent samples was performed to assess pre-test and post-test differences in each of two groups, while a Student's t-test for independent samples was performed to compare the two groups after 3 months. Heuristic learning proved to be the most effective method for improving teamwork skills. The results may make an important contribution to future teacher training on the most effective teaching methods for developing students' soft skills.

Comparison of Malaysia's Bachelor of Dental Technology curriculum with three other countries: Proposing a basic curriculum framework

INTRODUCTION

A dental technologist is one of the most essential allied dental health professionals and the dental technology curriculum should be comprehensively reviewed on a regular basis. This study aims to compare the only existing Bachelor of Dental Technology (BDT) curriculum in Malaysia with BDT programmes offered by other well-established universities, and map out the similarities and differences, as well as to explore future recommendations and propose a new curriculum framework.

MATERIALS AND METHODS

A descriptive analysis was carried out using Laurie Brady's four-stage strategy. First, available curriculum materials were collected from four different institutions' electronic webpage: AIMST (Malaysia), GU (Australia), UO (New Zealand) and CMU (United Kingdom), and then compared based on three key domains: curriculum contents, teaching and learning strategies and assessments. Following that, the similarities and differences between various curricula were identified. Future recommendations and a curriculum framework were then proposed.

RESULTS

The core BDT curriculum content is concurred upon by all four universities, with an emphasis on basic sciences, laboratory materials, practical sessions and research projects. However, the credit weightage for each course or module varied across the four institutions, with some offering unique subjects and implementing different teaching methods and assessments. A simple BDT curriculum framework with a proposed syllabus was designed based on the three key domains and future recommendations for curriculum improvement were explored.

CONCLUSION

The present study identified several areas for Malaysian BDT curriculum development and improvement. The proposed framework can be a guide for Malaysian dental schools in designing a comprehensive dental technology programme.

[Application of teaching method for the interpretation of acupoint names in the course of Science of Meridians and Acupoints]

The paper summarizes the valuable experience of the famous teachers of all generations in the teaching & research room of meridians and acupoints of Beijing University of CM. The shortcomings are presented when the acupoints are explained in accordance with the flowing route of meridians in classroom teaching of Science of Meridians and Acupoints. Hence, it is proposed that the acupoint names should be interpreted specially for the acupoints distributed on the same meridians or adjacent ones. It is suggested to emphasize the correlation of each acupoint with its adjacent ones from the perspective of the cultural connotation of acupoint names, and then, the differences and similarities in their clinical indications can be analyzed. Eventually, a new approach to the classroom teaching of Science of Meridians and Acupoints may be provided to guide the excavation of traditional cultural connotation and establish the cultural self-confidence and professional identity.

Effect of Teaching Method on Exercise Execution in Adolescents' Use of Outdoor Fitness Equipment

The use of outdoor fitness equipment (OFE) is an effective strategy to promote physical activity. The equipment normally includes information panels with phrases and images describing appropriate exercises. However, as using this equipment inappropriately is a potential problem, it is important to find an optimal unsupervised instruction method for correct exercise execution. Our objective in this study was to determine which of several exercise prescription methods, without direct professional supervision, might best instruct adolescents to correctly engage in upper limb motor execution on outdoor flexion-extension equipment. A total of 54 adolescents from a middle socioeconomic level in northwest Spain participated in this descriptive and quasi-experimental study. We randomly assigned members of this convenience sample into three groups who received either video instruction, instruction via images or written panel instructions. We used observational methodology in videographic analysis to evaluate the mistakes participants made in motor execution with each instructional method. We utilized different analytic techniques from observational methodology: statistical analyses (means, standard deviation, confidence intervals, ANOVA, etc.) and detecting T-Patterns with Theme and polar coordinate analysis using HOISAN. Participants who relied on video instructions committed fewer errors than those who relied on panel instructions. The video method prevented loss of information that occurred when instructional images were used. We suggest including a QR code on outdoor fitness equipment in open-air parks to permit users to download an explanatory video to their mobile phones.

The Use of 3-D Models of Echocardiographic Imaging Planes for Teaching Echocardiography Techniques for Use in Dogs and Cats

Echocardiography is an invaluable technique for the diagnosis of heart disease. The aim of this study was to develop 3-D models of healthy and diseased hearts of dogs and cats, and to evaluate their effectiveness in assisting veterinary undergraduates to understand echocardiographic imaging planes. Resin models depicting the main echocardiographic imaging planes of normal hearts were created, as well as example hearts with features of mitral degeneration in dogs and hypertrophic cardiomyopathy in cats. After a theoretical class, fourth-year students were randomly assigned to one of two groups (model group or control group). The model group had access to the 3-D models, along with self-explanatory text about echocardiographic imaging planes; the control group only had access to the self-explanatory text. Both groups were allowed 2 weeks to study their allocated resources, after which the students undertook an assessment to evaluate their learning and completed a questionnaire about their experiences and satisfaction with the respective teaching method. A total of 39 students participated in the study, 19 in the model group and 20 in the control group. Students assigned to the model group spent more time studying (p = 0.0027). The proportion of students who achieved a satisfactory grade in the assessment was 89.5% in the model group and 60% in the control group (p = 0.0449). The 3-D models facilitated, and significantly improved, the identification of cardiac structures and disease-associated abnormalities, and the learning process in general. Additionally, the models seemed to provide greater student motivation for studying echocardiography.

The Development and Prospects of Socioscientific Issues Teaching in the Context of Immersive Media Technology

Marshall McLuhan once proposed the concept of "global village," believing that with the help of electronic media, Earth has become indistinguishable from a community, and there is only one Earth for human beings and one world for all countries. Today, with the continuous development of media technology, the concept of a human destiny community has also gained the general consensus of people around the world. The global value of the human destiny community encompasses the interdependent concept of international power, the concept of common interests, the concept of sustainable development, and the concept of global governance. In particular, the concepts of sustainable development and global governance have been advocated by the public, which in turn has led to extensive public discussions on Socioscientific Issues (SSI), in which the teaching of SSI is gradually considered by the international science education community as one of the important goals of science education. The current issues and challenges facing SSI teaching and how immersive media technologies can facilitate SSI teaching have become important issues of keen public interest.

Curricular Considerations for Preparing Student Pharmacists to Prescribe Hormonal Contraception

In 2014, the pharmacist's role in the United States expanded to include prescribing hormonal contraception, and this practice is currently addressed by policy in 14 states and the District of Columbia. Training and education requirements for this expanded scope of practice vary between states and are changing rapidly. The objective of this review is to examine how student pharmacists are taught to provide contraceptive care, specifically for prescribing ongoing hormonal contraception and emergency contraception, and to identify potential gaps in the United States pharmacy curricula related to contraception. Despite steady adoption into community pharmacy practice, there is sparse literature assessing educational methods used to teach contraceptive care. This review offers recommendations to promote consistent and comprehensive student pharmacist education in providing contraceptive care across institutions, regardless of state policy status.

New Direct and Indirect Ophthalmoscopy Teaching Methodology for Veterinary Doctors

Ophthalmic diseases can reflect the presence of systemic disease in animals. Thus, specialists in veterinary medicine must master the technique of fundus examination. To aid in the acquisition of this skill, we developed a teaching methodology using a low-cost model that students can build themselves and a device that allow for the examination of the animal's retina to teach the techniques of direct and indirect ophthalmoscopy in veterinary medicine.

Abstract No. : ABS0260: Comparison of phantom cadaver based simulations with blue phantom model for teaching ultrasound guided regional anaesthesia: a randomised controlled trial

Background and Aims:

Various methods of simulation have different advantages and disadvantages.This study was aimed to compare the block performance of novice post-graduate students of anaesthesiology after teaching them ultrasound guided regional anaesthesia on blue phantom model or cadaver-based phantom model.

Methods:

This study was conducted in the Department of Anaesthesiology and Critical Care and Department of Anatomy at a tertiary medical college hospital.

Video lecture on ultrasound knobology and transducer movement was given to all study participants. In group BP, participants trained on blue phantom model. In group CP, participants trained on fresh human cadaver model. After training, participants were shown video of supraclavicular brachial plexus block,and finally performance was assessed on patients.

Results:

The median block performance time was 525.0 seconds in group BP with an interquartile(IQR) of (494-552.5) and 440.0 seconds in group CP with an IQR of (419.5-487.5)(table 1).

This difference was statistically significant (p<0.001). The median image quality score was 3.0 in group BP with an IQR of 2-3, and it was also 3.0 in group CP with an IQR of 3-4, and it was statistically significant (p = 0.00398) (table 2).

Conclusion:

Time taken to perform brachial plexus block was less in the cadaver phantom group compared to the blue phantom group. The image quality scores and number of attempts required to perform brachial plexus block were statistically significant between groups. Novices trained on cadavers had better transducer target orientation and were able to identify ultrasonographic artifacts better than those trained on the blue phantom.

Basic Skills in Higher Education: An Analysis of Attributed Importance

Today, the skills-based approach is increasingly in demand by companies due, in large part, to the fact that it favors the management of human resources by focusing on individual capabilities; which, finally, improves the job profile of a company. As a result, choosing the right candidates has become increasingly selective. Universities, therefore, need to teach skills to improve the incorporation of graduates into the workplace making it as successful as possible. For this reason, it is of special relevance to know if college students consider that the acquisition of skills is key for their incorporation into the workplace. The main objective of this study was to analyze and compare the importance assigned to the acquisition of basic skills in the university education of 694 students studying four different bachelor degrees: pedagogy, early childhood education, primary education, and psychology. For this purpose, a Likert-type questionnaire on basic skills was distributed with four possible options and the following five dimensions that grouped basic skills: organizational and planning capacity; access to information sources; analysis and synthesis of texts, situations, and people; teamwork; and problem solving. The results show that as a whole all students across different bachelor degrees gave a high score to the acquisition of basic skills, with early childhood education students giving it greater importance compared to the students from other disciplines and, more specifically, differences were observed in some dimensions depending on the bachelor degree that they have started.

Factors Influencing Nursing Students' Immersive Virtual Reality Media Technology-Based Learning

Background/objectives: This study aims to identify the effects of cognitive and emotional variables related to immersive virtual reality media technology on learning for nursing students. Methods/Statistical analysis: The subjects of this study were 121 nursing students from a university in area D. After experiential learning with virtual reality from 6–8 June 2019, data was collected through questionnaires. For virtual reality learning, VIVE’s hTC VIVE ECO CE model was used. The collected data was analyzed using the IBM SPSS 26.0 program. Multiple Regression Analysis was used to analyze the factors influencing the subject’s virtual reality learning effects. Findings: The learning effects of the virtual reality medium had a statistically significant positive correlation with the virtual reality technology recognition, sensory immersion, realism, learning satisfaction, learning necessity, and continuous use intention (p < 0.001) scores. In personality traits, only Openness, Extraversion (p < 0.01), and Conscientiousness (p < 0.05) had a statistically significant positive correlation. As a result of regression analysis, the explanatory power of the learning effect of the virtual reality medium was 63.9% (F = 53.61, p < 0.001), with learning satisfaction, sensory immersion, continuous use intention, and Extraversion being significant influencing factors (p < 0.05). Improvements/Applications: This study is meaningful in the sense that it provided strategic implications for the teaching and learning method of virtual reality technology-based learning by considering the insights necessary to develop a learning program using virtual reality technology, according to the characteristics of virtual reality technology, and the learner’s cognitive and psychological variables.

Pathophysiology teaching reform during the COVID-19 pandemic

The Coronavirus Disease 2019 pandemic has changed the way most people live and work, including the way in which students undertake study. To protect students during the pandemic, most schools in China adopted a study-at-home model. Under these circumstances, the pathophysiology teaching team at Tongji University considered how to reform teaching methods to minimize the impact of the pandemic on students' curriculum studies. This article describes our teaching reforms in detail, notably a combination of online education resources, online discussion courses, and a WeChat study group. We compared the effects of the reformed and traditional teaching approaches, including student performance and student evaluation of the reformed teaching methods. Analysis showed that although students were generally worried about the impact of the pandemic on their curriculum studies, their overall performance was not affected by the reformed teaching methods. Of interest, compared with traditional teaching, the proportion of students with higher final test scores (≥90 points) actually increased. The revised teaching methods promoted the learning of some students externally and internally and enhanced their enthusiasm for medical study and their academic performance. These approaches could be applied as a reference for future course arrangements after the pandemic.

Key Factors in the Application of Sharestart to Enhance the Learning Attitude of Students

Under the background of globalization and the popularity of distance learning ande-learning channels provided on the Internet, teaching methods that encourage the self-directed learning of students are becoming popular. There is an increasing number of domestic teachers joining in the practice for change. The various teaching methods that make the students acquire critical thinking skills can be summarized as learning by doing, critical thinking learning, multiple assessments, team discussion teaching, and cooperative learning. With the teachers of the universities in Shanghai as the questionnaire analysis objects, a total of 360 copies of questionnaires were distributed, and 256 valid copies were retrieved, with the retrieval rate of 71%. The research results are summarized as follows. (1) The “mental adaptation and engagement of students” is the most emphasized dimension, followed by the “professional development of teachers,” “administration and parent support,” and “material and teaching strategy.” (2) The top five emphasized indicators, among 14, are the ordered cultivation of self-study and thinking habits, the development of the professional community for the collaborative lesson study of teachers, the support and cooperation of the president and the administration, adoption of heterogeneous grouping, and co-learning, discussion and cooperative learning. According to the results, it is expected to propose more definite practice directions for teachers intending to attempt such a teaching method, as well as provide some specific suggestions for the first movers of Sharestart.

Application of the presentation-assimilation-discussion class in oral pathology teaching

OBJECTIVES

The presentation-assimilation-discussion (PAD) class is a novel teaching method in which half the class time is allocated for the instructor's presentation and the other half for student's assimilation and discussion. This study evaluates and compares the teaching outcomes of the PAD class and traditional lecture-based method in oral pathology courses in School of Stomatology, Kunming Medical University.

MATERIALS AND METHODS

The experimental and control groups included 88 undergraduates from Class 2017 and 72 undergraduates from Class 2016, respectively. The PAD method was applied on the experimental group in 2019, whereas the traditional lecture-based method was applied on the control group in 2018. The two groups' teaching outcomes were compared using final theory tests, biopsy diagnostic tests, and questionnaires. The Mann-Whitney U-test and independent-sample t-test were adopted for statistical analysis.

RESULTS

In five multiple-choice questions examining the same knowledge point from final theory tests, the distribution of the final scores showed a statistically significant difference between the two groups (p < 0.05). In the biopsy diagnostic tests, the experimental group scored higher than the control group (p < 0.05). In the questionnaires, there was no statistically significant difference for the "enhancing knowledge mastery" item (p > 0.05). However, the experimental group showed significant superiority in the remaining nine items (p < 0.05). [Correction added on August 30, 2021, after first online publication: The data value p was corrected in the last sentence of result section.] CONCLUSIONS: Compared with the traditional lecture-based teaching, the PAD class stimulated a passion for learning among students and results in improved teaching outcomes. Therefore, the application of PAD class in oral pathology teaching should be recommended.

The effect of live demonstration and flipped classroom with continuous formative assessment on dental students' orthodontic wire-bending performance

BACKGROUND

Wire-bending skills is commonly taught through live demonstrations (LD) though flipped classroom (FC) method has gained popularity. Continuous formative assessment promotes personalised learning via closely monitored progress, with the identification of students' strengths and weaknesses. This study aims to evaluate the effects of LD and FC teaching methods, supplemented with continuous formative assessment, on dental students' learning of wire-bending skills for six types of removable orthodontic appliance components. A deeper understanding of the relative effectiveness between LD and FC teaching methods can help identify the most appropriate method to achieve student learning objectives, which is especially important given the current Covid-19 pandemic.

METHODS

Forty third-year undergraduate dental students were randomly assigned into FC (n = 20) or LD (n = 20) cohort. Each student attended six teaching sessions, each to teach students' competency in fabricating one type of wire component, for a total competency in fabricating six wire components over the course of six teaching sessions. Either LD or FC teaching methods were used. After each session, wire assignments had to be submitted. Wire assignments were then evaluated using a blinded wire-bending assessment protocol. As part of their formative assessment, the assessment results were distributed to students, lecturers, and technicians before the next session. After the first session (T0) and at the end of all six sessions (T1), students completed a self-reported questionnaire.

RESULTS

The mean wire-bending scores for FC were significantly higher than LD for two of the six assignments, namely the Adams clasp (p < 0.01) and Z-spring (p = 0.03). Scores for both LD and FC increased significantly over time, which may be attributed to formative assessment. There was no statistically significant correlation between wire-bending scores and video usage. Students were satisfied with both teaching methods, according to T0 and T1 questionnaires.

CONCLUSIONS

Both LD and FC are equally effective in transferring practical orthodontic wire-bending skills and well-received by students. Continuous formative assessment may have enhanced students' learning of orthodontic wire-bending skills. Further studies with control group are recommended to investigate the effect of formative assessment on teaching practical dental skills.

How to Develop Entrepreneurial Talent More Effectively? A Comparison of Different Entrepreneurship Educational Methods

Recently, scholars have begun to shift focus toward the effectiveness of different teaching methods for entrepreneurship education. However, the establishment of a unified and clear standard for the division of entrepreneurship educational methods remains unfulfilled, affecting the accuracy of research conclusions. In the present study, for the first time, the aim was to divide the entrepreneurship educational method into the classroom teaching method (CTM) and the extracurricular activity method (EAM) from the perspective of competency level training. On the basis of the modified planning behavior theory, the influence of entrepreneurship education on entrepreneurial intention (EI) was explored. In the present study, 514 college students of 14 universities in China were surveyed. The results reveal that the CTM and EAM had a direct positive bearing on EI, with indirect impact exerted by attitude toward entrepreneurship (ATE) and perceived behavioral control (PBC). Although the direct effects of the two teaching methods were similar, EAM could effectively improve ATE and PBC, thereby resulting in a positive effect on EI to a greater extent. Further observations were made that the participation of research University students in CTM was significantly lower than that of applied University students, leading to lower EI. Additionally, higher EI could be attributed to the more active participation in EAM of male students than female students, while no significant difference was indicated between different majors in EI. The results are of significant reference value for promoting the reform of entrepreneurship education and improving the quality of entrepreneurship education in colleges and universities.

Learning Basketball Using Direct Instruction and Tactical Game Approach Methodologies

This study was to analyze and compare the learning acquired by the students in the sport of basketball in two different methodologies. The sample was composed of 40 students divided into two groups. The intervention programs had previously been validated. A descriptive analysis of the learning indicators, a t-test for independent samples to identify the differences between the methods, and a t-test for related samples to analyze the differences in each group were performed. There are differences between the performance profiles of students in the Direct Instruction in Basketball program and those in the Tactical Game in Basketball program in nine variables. Significant differences are found in the situations of dribbling, shooting, passing and movement, spacing, off-ball defense, and help and in the performance indicator for decision making, execution, and total, which are favorable to the Tactical Game in Basketball program. The students of the Direct Instruction in Basketball program only improved in three variables after the program, while the Tactical Game in Basketball students improved in thirteen variables. It is recommended that the teachers at the schools use the Tactical Game in Basketball methodology for their basketball teaching lessons, because student learning is better than in the Direct Instruction in Basketball program.

Application of microlecture teaching methods in standardized residency training during COVID-19 in Wuhan: a randomized, controlled study

BACKGROUND

Providing high-quality training to residency students during the coronavirus 2019 (COVID-19) pandemic has been a goal of our institution. Since 2108, we began to take microlectures to students teaching. Microlectures are online presentations, and the microlecture teaching method has many advantages, such as a short teaching time, situational resource composition, diverse communication, strong pertinence and can attend microlectures from home. The aim of the present study was to evaluate the advantages of the microlecture teaching method on students in standardized residency training.

METHODS

Students from our department were randomly divided into the traditional teaching group (control group) and the microlecture teaching group (observation group). The teaching duration for both groups was 3 months. All students were assessed on basic knowledge of the neurology before enrollment. After the teaching session, the students were assessed on teaching effect, theoretical operation, and clinical practice satisfaction. The students also evaluated the teachers, and the teachers evaluated the students.

RESULTS

A total of 84 students participated in the study and were divided equally into the observation group (42 students) and the control group (42 students). The results showed that the rate of reaching the standard of teaching effect, achievement of theory and operation, satisfaction with clinical practice, the student's grades by teachers, and student satisfaction with teachers were significantly higher in the observation group than in the control group (all P<0.05).

CONCLUSIONS

The microlecture teaching method can effectively improve the clinical teaching effect for neurology students and should be adopted in clinical teaching, especially during the COVID-19 pandemic.

Not yet a dinosaur: the chalk talk

This article discusses the chalk talk's potential as an active learning method. Although chalk talks are a form of interactive lecture, they have received little attention in the medical education literature compared with other active learning methods such as team-based learning and simulation. One of the authors (C. K. L. Phoon) has used chalk talks to teach congenital heart defects to first- and third-year NYU medical students for many years. His chalk talks have consistently earned among the highest teaching scores, and students have noted their strengths of being more interesting, clear, and tangible than didactic lectures. Using the teacher and student perspectives, we examine the chalk talk's strengths and weaknesses compared with common passive and active learning methods. Chalk talks create a real-time, shared space that facilitates the active learning goals of helping students build, test, and revise mental models (conceptual frameworks). The limited amount of information that can be presented and the ability to solicit and arrange students' ideas on the board lead to the cocreation of valuable conceptual frameworks. Chalk talks require less restructuring of teaching sessions than other active learning methods and are best suited to topics that hinge on understanding of concepts. We advocate for the chalk talk to be reexamined as a promising educational tool given its strengths and the successes that other active learning methods have shown. Furthermore, we provide guidance to help educators deliver chalk talks and discuss future studies that would advance understanding of this powerful teaching tool.

Compared with conventional teaching, this system can effectively improve practical operation test scores of students, meanwhile, it has higher interest, interactivity and helpfulness for knowledge learning, and improve independent learning ability, learning effect and memory depth, so student's satisfaction is higher.

Validation of an instructional module to help dental students learn to avoid plagiarism

OBJECTIVE

This study aimed to validate the learning effectiveness of an instructional module in helping first-year dental students and international graduate advanced standing students learn to avoid plagiarism in their scientific writing.

METHOD

The module was administered to a total of 226 first year dental students (157 at the University of Pittsburgh, in 2018 and 2019; 69 at the University of Illinois at Chicago, in 2019), and a total of 102 international graduate advanced standing students at the University of Illinois at Chicago, in 2019 and 2020. Psychometric analysis of the module's test items confirmed reliability and validity.

RESULTS

An independent sample t-test performed on the module pretest scores determined that the first -year dental students entered their programs with more knowledge about plagiarism than the international graduate advanced standing students. Mean differences were calculated between pretest and posttest scores for each group and indicated that the module was equally effective at helping both groups learn to avoid plagiarism. An independent sample t-test compared the posttest mean scores of the 2 groups and determined that the first -year students achieved a greater learning outcome from the module. An independent sample t-test for Equality of Means with Levene's Test for Equality of Variances were performed to compare the mean differences between posttest and pretest scores for the 2 groups. These tests indicated that the 2 groups learned to avoid plagiarism at the same rate.

CONCLUSIONS

The instructional module proved to be valid, reliable, effective, and time-efficient in improving student knowledge about avoiding plagiarism.

The effectiveness of different teaching methods on medical or nursing students: Protocol for a systematic review and network meta-analysis

BACKGROUND

One of the major challenges in nursing and medical education is to foster the critical thinking ability and autonomous learning ability for students. But the effect of different teaching methods on these abilities of nursing or medical students has not been conclusive, and few studies have directly compared the differences in the effects of different teaching methods. As a result, it is necessary for students to evaluate the impact of different teaching methods on critical thinking ability and autonomous learning ability.

METHODS

A systematic search will be performed using Chinese National Knowledge Infrastructure, Wanfang Data (Chinese database), VIP Information (Chinese database), Chinese Biomedical Literature, and English language databases, including PubMed and Embase, Web of Science, CINAHL Complete (EBSCO0, Cochrane library to identify relevant studies from inception to July 10, 2020. We will include random controlled trials that evaluated the different teaching methods. The Quality Assessment of Diagnostic Accuracy Studies 2 quality assessment tool will be used to assess the risk of bias in each study. Standard pairwise meta-analysis and network meta-analysis will be performed using STATA V.12.0, MetaDiSc 1.40, and R 3.4.1 software to compare the diagnostic efficacy of different hormonal biomarkers.

RESULTS

The results of this study will be published in a peer-reviewed journal.

CONCLUSION

This study will summarize the direct and indirect evidence to determine the effectiveness of different teaching methods for medical or nursing students and attempt to find the most effective teaching method.

Effects of Student Interests on Engagement and Performance in Biomechanics

There is a need for pedagogical techniques that increase student engagement among underrepresented groups in engineering. Relating engineering content to student interests, particularly through biomechanics applications, shows promise toward engaging a diverse group of students. This study investigates the effects of student interests on engagement and performance in 10th grade students enrolled in a summer program for students underrepresented in the science, technology, engineering, and mathematics fields. The authors assessed the effects of interest-tailored lectures on student engagement and performance in a 5-week program with bioengineering workshops, focusing on the delivery of biomechanics content. A total of 31 students received interest-tailored lectures (intervention) and 23 students received only generic lectures (control) in biomechanics. In addition, the authors assessed the effects of teaching method (lecture, classroom activities, and laboratory tours) on student engagement. The authors found interest-tailored lectures to significantly increase student engagement in lecture compared with generic lectures. Students that received interest-tailored lectures had an insignificant, but meaningful 5% increase in student performance. Students rated laboratory tours higher in engagement than other teaching methods. This study provides detailed examples that can directly assist student teaching and outreach in biomechanics. Furthermore, the pedagogical techniques in this study can be used to increase engagement of underrepresented students in engineering.

Dental and physical therapy faculty collaborate in assessing and educating dental students on musculoskeletal disorders

INTRODUCTION

Research shows 54% to 93% of practicing dentists suffer from musculoskeletal disorders (MSDs), with many developing afflictions early in their careers. Studies also show that dental students are developing MSDs early in their professional education.

OBJECTIVE

The research goal was to quantify the prevalence, anatomical location and initial onset of MSDs among first-year dental students. The study also assessed the students' self-reported opinion as to whether there were enough educational touchpoints to improve their ergonomics in daily activities.

METHODS

At the conclusion of a 9-month preclinical restorative course, that included 2 lectures on MSDs, ergonomics, and postural cueing sessions, a dental and physical therapy faculty member administered a survey to 143 first-year dental students. This survey included questions about the history and presentation of the students' MSD symptoms and their opinion on the relative value of the educational interventions.

RESULTS

There was a 96.5% response rate to the survey with 87.8% of students reporting mild to moderate pain. The cervical spine (41.7%) and hands (42.4%) were the most common areas afflicted. 55.4% reported pain commencing 1 month after starting in the simulation clinic. Over 60.9% of students "agreed" or "somewhat agreed" that the 2 sessions of hands-on ergonomic educational interventions resulted in improved biomechanics and students requested additional educational resources.

CONCLUSION

Dental students are developing MSDs as soon as 1 month after commencing dental school. Dental education should include ongoing ergonomic training throughout the curriculum to help students prevent MSDs.

Endotracheal intubation training to medical practitioners: Comparison of the modified 4-step Payton's training method and Halsted's training method in a simulated environment

INTRODUCTION

The ability of physicians to perform endotracheal intubation by laryngoscope is one of the essential skills. The purpose of this study was to evaluate the effectiveness of the four-step python training method with the Halsted's "See one, Do one, and Teach one" training method in endotracheal intubation competency in simulated environment.

MATERIALS AND METHODS

This quasi-experimental study was performed on two independent groups with posttest. The statistical society consisted of eighth-semester medical students referred to the emergency medicine unit. The experimental group received a modified four-step python's training method that modified for small groups, and the control group received the Halsted's "See one, Do one, and Teach one" training method. Researcher-made checklist used to rate participant competency as posttest. Data were analyzed using SPSS 19 software.

RESULTS

Sixty-seven students volunteered for the experimental group and 57 students for the control group. In posttest, the experimental group more competent than the control group significantly (P < 0.001). Furthermore, the training course satisfaction of the experimental group was significantly higher than the control group (P < 0.001).

DISCUSSION AND CONCLUSION

Modified python training method for small groups has shown a better effect on student performance. This finding is consistent with previous researches. Modified four-step python's training for small group with an emphasis on peer to peer teaching and receiving feedback from peer can be related to the effectiveness of this training. Further research is recommended in other clinical education settings.

Comparison of students' perception of problem-based learning and traditional teaching method in a Nigerian dental school

OBJECTIVES

To evaluate the perceptions of dental students on problem-based learning, PBL, in comparison with the traditional lecture (TL) method.

METHODS

This comparative study was conducted amongst 72 dental undergraduates. PBL was introduced to the students before the commencement of course. PBL method was used by the student to learn about cariology, whilst other lecture topics were taught by the TL. Students were not informed at the beginning of the course about end of course assessment of learning and teaching methods to limit their bias. The study was approved by the institution's ethics committee, and informed consent was obtained from participants at the end of the course to recruit them into the study. The students worked in small groups to solve tasks on clinical case scenarios. Four class sessions were held for presentations and discussions. The students' perceptions concerning the two teaching methods were sought by the use of an anonymously completed questionnaire. Six perceived factors that influenced the teaching and learning process were extracted from the twenty-two-perception-item questionnaire using factor analysis. Paired sample t test was used for comparison of means.

RESULTS

The highest mean scores for all six perceived factors were observed in the PBL method. There were statistically significant differences (P < .05) between PBL and TL teaching methods for all the perceived factors; ("Challenge critical thinking," "Communication with peers," "Usefulness as pedagogical method," "Organization" and "Interaction between students and tutors") except for the perceived factor "Adequacy of teaching." The mean for most of the perception items was highest in the PBL method compared to TL. The perception item "Able to provide intellectual stimulation" had the highest mean score (4.21 ± 0.76) for the PBL method, whilst it was "Laboratory exercise" (4.14 ± 0.68) for TL.

CONCLUSIONS

Students' perception of the two educational methods investigated showed a preference for the PBL method. The students felt that PBL provided a higher ability for intellectual stimulation.

The Effect of Live-Video Demonstration on Dental Students' Orthodontic Bending Performance

The aims of this study were to evaluate the effects of a live-video teaching tool on the performance of dental students in bending an orthodontic vestibular arch and to assess the students' perceptions of the technology. All 135 fourth-year dental students in the 2018 academic year at Hacettepe Dental School, Ankara, Turkey, were invited to participate in the study; after exclusions, the remaining 116 were randomly divided into two demonstration cohorts. These students had no prior experience bending an orthodontic wire. Cohort 1 (control, N=58) was shown a conventional live demonstration of the orthodontic bending of a vestibular arch, and Cohort 2 (experimental, N=58) was shown a live-video demonstration of the same procedure. Both cohorts saw the demonstration before beginning the exercise and were evaluated afterwards on their performance of the procedure. In addition, the students' perceptions of the demonstration techniques were collected with a questionnaire. The results did not show any significant differences in the students' bending scores between the control and experimental cohorts (p=0.767). The median values on the questionnaire indicated almost no statistically significant difference in responses between the cohorts. The only significant difference was that Cohort 1 had a higher percentage who answered "yes" they would like to rewatch the demonstration than did Cohort 2 (p=0.024). In this study, the live-video technique was found to be as effective as a conventional live demonstration for orthodontic practical education, suggesting that either technique could be used as an appropriate method for training in orthodontic wire bending.

Peer-Assisted Learning in Dental Students' Patient Case Evaluations: An Assessment of Reciprocal Learning

Little research exists on reciprocal learning, a type of peer-assisted learning in which students act concurrently as both teacher and learner in small groups. The aims of this pilot study were to assess the feasibility of using case-based reciprocal learning with dental students and to assess its impact on students' satisfaction and perceived clinical reasoning, educational value, and use of evidence-based dentistry. In this quasi-experimental mixed methods study conducted in 2018, small-group sessions led by a third-year dental student were designed to expose second-year students to clinical portfolios prior to clinical rotations, promote evidence-based dentistry, and improve students' clinical critical thinking skills by having them work in small groups to teach and learn from each other. After the intervention, all 76 students in the sessions were invited to complete a survey with 11 Likert-scale items and six open-response questions assessing their engagement in learning, perceived educational value, and perceived quality of facilitation associated with reciprocal learning. Sixty-five students completed the surveys for a response rate of 86%. Among the survey respondents, 87.7% agreed/strongly agreed that the small groups facilitated enhanced learning, and 66.2% agreed/strongly agreed that they learned the material better because they had to teach it to their peers. Also, 74.6% agreed/strongly agreed that their clinical critical thinking improved, and 92.3% agreed/strongly agreed that they felt better prepared to complete a patient portfolio once they reach clinic. This study found that reciprocal learning had favorable outcomes in terms of students' perceptions of learning. The students reported that the small groups enhanced their learning, improved their comfort in asking questions in small groups, and exposed them to a variety of clinical situations.

A Tale of Two Teaching Methods: Students' Clinical Perspectives on Administering Dental Local Anesthetics

Various preclinical methodologies have been adopted by dental and oral health programs to develop student competence in administering dental local anesthetics (LA). Student-to-student practice is the most common preclinical training method. However, manikin simulation models have been introduced to avoid possible complications and ethical concerns with student-to-student injections. In 2017, the methodology was changed in the Bachelor of Oral Health program at The University of Sydney School of Dentistry in Australia from student-to-student practice to manikin simulation models. The aim of this study was to compare the students' learning experience, perceived confidence, and anxiety in giving their first injections to patients in these two preclinical training methods. A mixed-methods cohort design was used to compare the 2016 (n = 42) and 2017 (n = 32) oral health students' experiences and perceptions and evaluate students' clinical experience after commencing LA practice on patients. Students completed a questionnaire about their perceived level of confidence and anxiety before and after their first LA to a child and an adult for both infiltration and inferior alveolar nerve b lock (IANB) injections. Focus groups were conducted to further investigate the students' experience. The results showed that the perceived confidence and anxiety of the two cohorts did not differ significantly from each other. Although students found it difficult to transition into clinical practice without having experienced LA themselves, the manikin simulation practice provided a safe learning platform that avoided ethical and legal concerns. These findings support the use of manikin simulation models as an alte rnative method for dental local anesthetic preclinical training.

Reflective Journaling by Second-Year Dental Students During a Clinical Rotation

Reflection involves taking the time to deeply consider a past situation and examine areas of weakness or confusion. It allows identification of learning needs and the development of an action plan to improve future experiences. The aim of this study was to assess second-year dental students' ability to reflect in writing on a clinical rotation when prompted with a guided reflection template. The 76 second-year dental students enrolled in a periodontics clinical rotation course at one U.S. dental school in 2016-17 completed two reflective writing exercises during the semester. A total of 144 journals (after excluding incomplete journals) were analyzed individually by two evaluators following a rubric developed by Kember. This rubric combined Mezirow's seven levels of reflection into four categories: Habitual Action (HA), Understanding (U), Reflection (R), and Critical Reflection (CR). The first two categories are examples of non-reflective thoughts, and the latter two are reflective. The two sets of journals were also compared. On average, the journals contained 0.2% HA, 15.9% U, 73.8% R, and 10.1% CR, averaging 16.1% non-reflective thoughts and 83.9% reflective thoughts. Comparison of the students' first journal submissions to their second showed that the first journals averaged a higher percentage of reflective thought than the second journals: 85.2% vs. 82.7%, respectively. However, the first journals showed a lower average percentage of critical reflection than the second journals: 9.3% vs. 11.3%, respectively. Overall, a high degree of reflection was found in these students' journals after rotation in periodontics clinic, suggesting that reflective journaling can serve as a useful learning exercise to promote continual improvement during clinical training.

Impact of Blended Learning on Dental Students' Performance and Satisfaction in Clinical Education

The aim of this study was to evaluate the effectiveness of a blended learning model with a flipped classroom approach in a clinical dental education setting based on student performance and perceptions. Comparisons were made between blended learning and traditional methods for all fourth-year dental students in two consecutive cohorts in a conservative dentistry course at a dental school in Jordan. The 2016-17 cohort (control group) consisted of 364 students taught with conventional methods. The 2017-18 cohort (study group) consisted of 253 students taught with blended learning using a flipped classroom method. Performance measures were two exams (online and written), two assignments, inclinic quizzes, and clinical assessment. The study also assessed the number of posts made by students in the study group on an online discussion forum. The results showed that the study group students had significantly better performance on all assessments than the control group students. The students' overall grades in the blended learning cohort were an average 7.25 points higher than in the control cohort. Students who participated in the online forum also had better performance in the course: one participation correlated with 0.697 standard deviations higher score. Overall, students' perceptions were positive and supported the adoption of a blended learning model in the course. These results showing improved student performance provide support for blended learning and use of an online discussion forum.

[Exploration of new teaching mode of Science of Meridians and Acupoints based on three-dimensional practice platform]

The new teaching mode of Science of Meridians and Acupoints based on the practice platform was explored so as to promote the mutual benefits for both teaching and learning. As the basic course of acupuncture-moxibustion and tuina specialty, Science of Meridians and Acupoints is the core theoretical and practical course. Through the establishment of on-campus practice platforms, e.g. the Technique Association of Acupuncture-Moxibustion and Tuina, physical therapy room of acupuncture-moxibustion and tuina and the practical platform for promoting outside-campus medical service, in accordance with the teaching mode of "theory → practice → re-theory → re-practice", the class teaching of theory and the skill training were optimized, the three-dimensional practice platforms for teaching Science of Meridians and Acupoints was constructed, meaning "class teaching → on-campus practice → social service". This teaching mode motivates the enthusiasm of teaching and learning, improves the teaching quality of Science of Meridians and Acupoints, enhances the professional theoretical level as well as the clinical practice ability. Such teaching mode plays a positive role in the cultivation of talents of acupuncture-moxibustion and tuina.

[Exploration and practice of micro-video teaching of Characteristic Clinical Technology of Acupuncture and Moxibustion]

In this paper, the micro-video teaching mode was explored in the course construction of Characteristic Clinical Technology of Acupuncture and Moxibustion. The micro-video teaching contents include the academic thought, experience in diagnosis and treatment, characteristic technology and clinical manipulation of famous acupuncture experts in the Henan University of CM. Each micro-video film is designed within 15-18 min, including three sections of knowledge, i.e. basic theory, technological application and clinical manipulation. Each section is designed within 5-6 min. The construction of the teaching course of Characteristic Clinical Technology of Acupuncture and Moxibustion is the innovation of practice mode of TCM and the new approach to the inheritance of the experience of experts. The construction of micro-video teaching course propels the reform of teaching mode, improves the learning initiative of students and clinical manipulative ability so as to improve the teaching effect and quality.

The Effectiveness of Flipped Classroom in Health Professions Education in China: A Systematic Review

BACKGROUND

Flipped classroom has received much attention during the last few years in China, but inconsistent conclusions are made about the effectiveness this approach in health professions education. This review examined the findings of controlled studies published in Chinese in order to summarize the effects of the flipped classroom methodology. These studies focused specifically on undergraduate level of health professions students.

METHODS

A literature search was conducted using China National Knowledge Infrastructure (CNKI) and Wanfang Data Knowledge Service Platform in June 2019. No date restrictions were used. Peer-reviewed papers were reviewed and experimental studies were included if the study compared student outcomes using flipped classroom method versus traditional lectures. The revised version of the Kirkpatrick's model was applied to evaluate the effectiveness of the flipped classroom approach.

RESULTS

In total, 934 articles were obtained. Among them, 235 articles were full text reviewed and 59 met the inclusion criteria. Most of the student agreed that flipped classroom strategy was very helpful improving their self-learning ability, problem solving ability, teamwork, and communication skills, but reported increased workload and less-efficiency compared with traditional lectures. However, the majority of studies (n = 52) showed positive findings of the flipped classroom on changes in knowledge and skills, and 3 in negative. Among these 59 studies, there was little evidence of changes in behavior, organizational practice and patient outcome.

CONCLUSIONS

Better design with reduced content should be considered for instructors to promote learning effectiveness. Long-term effects of flipped classroom should be considered in future studies.

[Application of the interaction teaching mode integrated with virtual anatomy platform in teaching Meridian and Acupoints]

OBJECTIVE

To observe the effect of the interaction teaching mode integrated with Visible Body virtual anatomy platform in teaching Meridian and Acupoints.

METHODS

A total of 60 students in the class of 2017 in the discipline of acupuncture-moxibustion and tuina, Xiangnan University were recruited and randomized into an observation group and a control group, 30 students in each one. In the control group, the traditional practical teaching mode was used. In the observation group, the interaction teaching mode integrated with virtual anatomy platform was adopted. The teaching duration was 10 class hours in both groups. After accomplishing the teaching schedule, the practical examination was conducted in the localization of commonly-used acupoints, very useful acupoints and the dangerous acupoints as well as acupuncture manipulation techniques. Moreover, the degree of satisfaction was investigated among the students in the two groups and the self-learning ability was evaluated in 3-month follow-up visit.

RESULTS

In the observation group, the scores for the localization and acupuncture manipulation of commonly-used acupoints, very useful acupoints and the dangerous acupoints, as well as the degree of satisfaction of the 3 items, i.e. interesting, interaction and leaning-assistance were all higher than those in the control group (P<0.05). The degree of satisfaction in the acceptance and leaning-participation, as well as the scores of self-learning ability in 3-month follow-up visit were not different statistically between the two groups (P>0.05).

CONCLUSION

The interaction teaching mode integrated with virtual anatomy platform improves the effect on teaching Meridian and Acupoints and achieves the high student satisfaction.

Creating an Efficient Learning Model: Students' Perceptions and Outcomes of an Active Learning Fixed Prosthodontics Course

With the extensive amount of learning required in dental schools, educators are constantly seeking more efficient learning models. The aim of this retrospective study was to evaluate a fixed prosthodontics course after its curriculum transitioned from a traditional lecture format to an active learning structure over the course of five years. In this retrospective, mono-centered study completed in 2018 at a U.S. dental school, data from the school's fixed prosthodontics course exams, National Board Dental Examination Part II (NBDE II), and the operative portion of the Western Regional Examining Board (WREB) licensure exam were collected for 381 students from the inaugural Class of 2015 to the Class of 2019. Data were evaluated for two groups based on method of instruction: the Classes of 2015 and 2016 were taught in a traditional model, and the Classes of 2017-19 were taught in the modified learning model. The data showed a 30% reduction in time students spent in the classroom and simulation clinic as compared to the previous model. The modified learning model reduced time spent in lecture, length of the course, and number of projects needed, while student performance remained consistent. Students in the active learning classes were able to pass all assessments including practical examinations at the same rate as previous classes using traditional learning methods. Students' performance on standardized national exams (NBDE II and WREB licensure exams) remained consistent among the graduating classes, and scores were comparable to the national average. Although limited in scope, this study suggests that it is possible to reduce contact time in fixed prosthodontics and maintain performance by increasing student engagement through active learning techniques.

[Teaching exploration and practice of research experiment of experimental curriculum in Principle and Application of Acupuncture-Moxibustion Equipment]

In order to improve students' ability of performing investigative study, promote practical teaching, optimize teaching philosophy and methods, we integrated the subject frontier dynamics and development achievements and knowledge into teaching content, the teaching exploration and practice of research experiment of experimental curriculum in Principle and Application of Acupuncture-Moxibustion Equipment was performed. The experimental curriculum was used as starting point. Before experimental teaching, the learning of knowledge was completed by theoretical study and key self-study points. During experimental teaching, experimental report and analysis report were completed by group collaboration. After experimental teaching, the research experiment was reported, analyzed and summarized by group discussion and presentation. With innovate, flexible and diverse teaching forms to guide the students to experience the process of "asking questions→conducting experiment→observation→recording→analysis→conclusion→verification of assumptions-discussion→reports", the ability of independent thinking and active investigation was improved; teaching level and teaching effectiveness were promoted.

Structured DVD Education: Impact on Teaching Satisfaction and Anxiety Among Patients With Leukemia and Lymphoma and Their Family Members

BACKGROUND

Many factors can interfere with a patient's ability to cope with a new cancer diagnosis. The method of education delivery may improve satisfaction with teaching and reduce anxiety. Structured DVD education combined with other teaching methods has shown positive results. However, few such studies have included family members.

OBJECTIVES

The purpose of this study was to evaluate the impact of structured DVD education versus standard one-on-one education on satisfaction with teaching and on anxiety among patients newly diagnosed with leukemia and lymphoma and their families.

METHODS

A post-test randomized controlled trial study design evaluated the effects of structured DVD education compared to standard one-on-one education.

FINDINGS

Family members in the intervention group had higher satisfaction with teaching than those in the control group; this difference was found to be statistically significant.

[Teaching method of the basic ability of acupuncture in training the manipulation skills in Techniques of Acupuncture and Moxibustion]

Through checking the ancient books and the articles at the modern times and combining the disciplinary characteristics of techniques of acupuncture and moxibustion, the training of manipulation skills was discussed. It is proposed that during the teaching of the techniques of acupuncture and moxibustion, the most basic ability of needling technique should be trained in the first place. This ability includes the ability of spiritual cultivation, the ability of tactile perception and the specific training for the needling techniques. The ability of spiritual cultivation refers to the consciousness concentration to the patient when providing acupuncture, which may promotes deqi and conducts qi to the affected area. The ability of tactile perception refers to the different feelings of different tissues under the hands before and after acupuncture, the perception to the different needling sensations corresponding to the chief complains of patients as well as the different body responses after acupuncture. In order to ensure the better learning results, the specific manipulations of needling techniques should be provided accordingly on the base of these basic training skills of acupuncture.

Method of teaching undergraduate students to perform root canal treatment: It's influence on the quality of root fillings

INTRODUCTION

This study aimed to assess whether the method of teaching endodontology influenced the quality of root fillings made by undergraduate students.

MATERIALS AND METHODS

The method of teaching endodontology at our institution was revised. Changes concerned: the programme (ie method of clinical training and summative assessment), and the supervision whilst performing root canal treatment on patients. An intermediate cohort (N=91) comprised partly students attending the former programme (involving patients) and partly students attending the revised programme (without patients). After succeeding in the summative assessment, the quality of the first root filling made by the student in a patient under supervision of either a general dental practitioner or an endodontist was evaluated according to pre-determined criteria. Data were analysed using Cohen's Kappa, Chi-square, Fisher's exact, Mann-Whitney and Kruskal-Wallis tests.

RESULTS

Sixty-two per cent (47 of 76) of root fillings made by students who attended the revised programme were of good quality, in comparison with 47% (seven of 15) of those made by students who attended the former programme (P=.274). Less complex treatments had better quality root fillings if students were supervised by endodontists (88% (14 of 16) good quality) than supervised by general dental practitioners (59% (22 of 37) good quality) (P=.045). Complex treatments did not differ in quality of root fillings for the supervision types (P=.825).

CONCLUSION

The quality of root fillings made by students who attended the revised programme seems at least as high as that of those who attended the former programme. Higher quality root fillings might be obtained under supervision of endodontists than under supervision of general dental practitioners.
