Effect of active learning and online discussions on the academic performances of dental students

A Novel Team-Based Approach to Oral Diagnosis Education: Case of the Week

BACKGROUND

Traditional oral diagnosis education often relies on passive lectures and individual case assessments. Team-based learning (TBL) offers an interactive alternative, but implementation challenges can exist. The 'Case of the Week (COW)' method presents a potentially modified TBL approach for oral diagnosis education.

OBJECTIVES

This study aims to evaluate the effectiveness of the COW method in enhancing student engagement for acquiring knowledge and diagnostic skills in oral diagnosis. Additionally, we seek to explore its impact on promoting teamwork and collaboration among students, as well as assessing overall student satisfaction with this learning approach.

METHODS

Students were invited to participate in a post-COW questionnaire. This questionnaire utilised a five-point Likert scale to gather student ratings across five distinct domains: Knowledge acquisition, Learning environment, Student preparedness for assessment, Student preparedness as a clinician and overall student experience with the COW activity.

RESULTS

The response rate was 75%, with 140 responses gathered from two groups of 70 students in each. The majority of students found COW activity valuable for acquiring knowledge (intellectual stimulation, critical thinking), teamwork and presentation skills and creating a comfortable learning environment. Furthermore, students indicated that the COW was more effective than traditional lectures in preparing them for future clinical practice. Furthermore, students reported that the COW motivated independent learning, facilitated research skills development and enhanced communication abilities.

CONCLUSION

The COW method has the potential to be an effective and engaging modified TBL approach for oral diagnosis education. By fostering knowledge acquisition, promoting teamwork and enhancing student satisfaction, it offers a dynamic and impactful learning experience.

Continuing professional development in general dentistry-experiences of an online flipped classroom

INTRODUCTION

Continuing professional development is a lifelong learning process. One pedagogical approach that can be used is active learning. Flipped classroom is a method that has been shown to improve deeper conceptual understanding. In an online setting, the method saves travel, time, and costs. To our knowledge, flipped classroom is rarely used in continuing professional education. This study in general dentistry explored experiences of an online flipped classroom course in continuing professional development.

MATERIALS AND METHODS

Fifteen dental hygienists, clinically active in general dental care, were interviewed. They were recruited from an online course on the latest classification system for periodontal diseases. The course had been conducted using an active learning and flipped classroom model. The interviews were semi-structured. Data were extracted using qualitative content analysis.

RESULTS

The experiences of the dental hygienists could be summarized in three themes: Stimulation of knowledge gain through self-paced studies, The ease of virtual networking among colleagues, and Fostering of direct practical application through collaboration.

CONCLUSION

New and emerging communication technology seems to open new possibilities for continuing professional development in general dentistry. Study participants felt that, in an online environment, mixing asynchronous and synchronous communication in a flipped classroom model facilitated learning in continuing professional development. Online active learning seems to work well in continuous professional development in general dentistry. After the course, the participating dental hygienists stated that they were able to use their new knowledge clinically and felt confident doing so.

Students' perceptions of virtual interactive clinical case-based learning: A comparative study with three different cohorts

Background/purpose

Since the introduction of virtual learning into dental education, students' perceptions of the effectiveness of virtual versus in-person learning formats have evolved for interactive clinical case-based learning (ICCBL). This study aimed to undertake a comparative analysis of three different cohorts that received various formats of ICCBL instruction.

Materials and methods

A survey was distributed to the Classes of 2023, 2024, and 2025 following each class completion of interactive clinical case-based-tutorials (ICCBT) as part of the Treatment of Active Disease (TxAD) course at Harvard School of Dental Medicine.

Results

A total of eighty-five participants from the three cohorts, twenty-three students from the Class of 2023 (virtual format, 71.9 % participation rate), thirty-one students from the Class of 2024 (combination of virtual and in-person, 91.2 %), and thirty-one students from the Class of 2025 (in-person, 83.8 %) completed the post-course survey. Across three classes, all cohorts were more likely to perceive the virtual format as more effective than in-person ICCBT. In addition, the classes were more likely to prefer virtual based classes compared to in-person tutorials in the future.

Conclusion

This study highlights the dynamic shifts in educational approaches to align with the evolving demands of contemporary students. Our findings show that all cohorts expressed a preference for virtual ICCBT sessions and perceived virtual ICCBT sessions as somewhat more effective for learning compared to in-person sessions. These findings challenge the notion that such sessions must be conducted in person, prompting further research and the exploration of potentially more effective and optimized educational methods.

Flipped classroom teaching model with video instruction improves skills in local anesthesia training

Background/purpose

Local anesthesia (LA) training is an essential clinical skill in dental education. However, the traditional teaching method of student-to-student injection has ethical concerns. This study investigated whether a flipped classroom (FC) teaching model with instructional videos improves students' skills in administering LA.

Materials and methods

Fourth-year dental students in 2017 (traditional teaching, n = 70) and 2018 (FC model, n = 79) were assessed for their ability to perform an inferior alveolar nerve block and lingual nerve block. The FC group watched pre-recorded videos prior to a hands-on training session. Skills were evaluated using a 24-item checklist converted to letter grades. Perceptions of the FC approach were also surveyed.

Results

The FC group showed statistically significantly higher final grades than the traditional teaching group (P < 0.05). Most FC students agreed that the videos improved clarity and learning objectives.

Conclusion

The FC teaching model with procedural video instruction improved skills and confidence in administering LA over traditional teaching methods. Videos can be a beneficial supplement in pre-clinical dental training.

Dental Students' Satisfaction With Web-Based Learning During the Initial Phase of the COVID-19 Pandemic: Mixed Methods Study

BACKGROUND

The COVID-19 pandemic has precipitated an accelerated shift in education, moving from traditional learning to web-based learning. This transition introduced a notable transactional distance (TD) between the instructors and learners. Although disease control and staff and students' safety are the top priorities during a pandemic, the successful delivery of education is equally crucial. However, the ramifications of this swift transition are particularly critical in the context of dental education. Dental education is inherently practice oriented, necessitating hands-on training and manual skills development, which poses unique challenges to distance learning approaches.

OBJECTIVE

This study aims to examine dental students' web-based learning satisfaction and experience of TD, investigate the predictors of web-based learning satisfaction, and explore the perceptions of students about the advantages and disadvantages of web-based learning.

METHODS

This study explored the factors associated with web-based learning satisfaction using TD theory during the transition to web-based education. Psychological factors that could influence satisfaction were adapted from the health belief model. We conducted a cross-sectional web-based survey of 345 dental students from 2 institutions in South Korea who were enrolled in the spring semester of 2020. Data were collected between July 8 and September 14, 2020. Qualitative analysis was used to examine responses to open-ended questions concerning perceptions of web-based learning.

RESULTS

A multivariate hierarchical linear regression model was used to analyze the effects of student characteristics, TD, and psychological factors (ie, perceived risk of infection and efficacy belief of web-based learning) on web-based learning satisfaction. The average score for web-based learning satisfaction was 3.62 (SD 0.84), just above the midpoint of the possible range (1-5). Self-regulated learning (β=0.08; P=.046), learner-instructor interaction (β=0.08; P=.03), and learner-content interaction (β=0.64; P<.001) were associated with higher levels of satisfaction. Moreover, a significant association was revealed between high efficacy beliefs in web-based learning (β=0.20; P<.001) and satisfaction. Although the learning structure (synchronous vs asynchronous) did not exhibit a significant association with satisfaction, the qualitative analysis results revealed that each structure possesses distinct strengths and weaknesses. The students in synchronous learning (79/345, 22.9%) recognized heightened autonomy in the "learning environment" (19/79, 24%); however, technical issues (28/79, 35%) and reduced concentration (15/79, 19%) were identified as downsides. Conversely, the students in asynchronous settings (266/345, 77.1%) emphasized unlimited access to learning content (74/266, 27.8%) and the flexibility of "learning in preferred time" (69/266, 25.9%). Nevertheless, challenges, such as self-management difficulties (66/266, 24.8%) and limited interactions (55/266, 20.7%), were evident.

CONCLUSIONS

The findings suggest that efforts to minimize TD, facilitating self-regulated learning and interaction among students and instructors, are critical for achieving web-based learning satisfaction. Moreover, establishing a common understanding among students regarding the necessity and efficacy of web-based learning during epidemics could enhance their satisfaction.

Effectiveness of blended pedagogy for radiographic interpretation skills in operative dentistry - a comparison of test scores and student experiences at an undergraduate dental school in Pakistan

BACKGROUND

Utilizing Blended pedagogy (BP) in radiographic skills may prove to be an effective teaching strategy. However, studies on the use of BP in dentistry are quite limited in Pakistan, where teaching has mostly been via traditional Didactic Lectures (DL); and radiographic interpretation skills of undergraduate dental students are suboptimal. Therefore, this study aims to assess whether utilizing BP to teach radiographic interpretation skills is an effective teaching methodology in Pakistan.

METHODS

This mixed-method study was conducted on final year dental students at Jinnah Medical and Dental College (JMDC). Two groups of students were utilized for this study, one taught by traditional DL and the other taught by BP for the same module. BP was conducted over six weeks. A post-module test was conducted in both groups. Additionally, the BP group completed a modified Community of Inquiry (CoI) survey tool and volunteered to discuss their experiences through a focused group discussion (FGD). Descriptive statistics were computed and independent sample t-test was used to analyse the difference between the scores of the two groups. Thematic analysis was performed for the qualitative data.

RESULTS

The mean post-test scores were found to be significantly higher in the BP group (61.0 ± 10.2) compared to the DL group (44.4 ± 12.3) (p = < 0.001, CI = 95%, Cronbach Alpha > 0.8). The mean scores for the modified CoI instrument were 4.0 ± 0.29 for the whole instrument; 4.25 ± 0.22 for Teaching Presence, 3.71 ± 0.23 for Social Presence and 3.97 ± 0.16 Cognitive Presence, with all three having a Cronbach's alpha > 0.75. Thematic analysis revealed that BP students mutually agreed that BP method was beneficial with the appreciation of strong support from the facilitator. However, challenges like interrupted power supply and increased effort requirement from students were pointed out.

CONCLUSION

Students taught radiographic interpretation skills with BP in comparison to DL had higher test scores and expressed a positive experience demonstrated via a modified CoI survey and FGD. Considering the encouraging results found, dental schools should incorporate BP in their teaching methodology and follow-up studies are needed to further support the use of BP as an effective teaching methodology in Dentistry.

A mixed method analysis of student satisfaction with active learning techniques in an online graduate anatomy course: Consideration of demographics and previous course enrollment

Online learning has become an essential part of mainstream higher education. With increasing enrollments in online anatomy courses, a better understanding of effective teaching techniques for the online learning environment is critical. Active learning has previously shown many benefits in face-to-face anatomy courses, including increases in student satisfaction. Currently, no research has measured student satisfaction with active learning techniques implemented in an online graduate anatomy course. This study compares student satisfaction across four different active learning techniques (jigsaw, team-learning module, concept mapping, and question constructing), with consideration of demographics and previous enrollment in anatomy and/or online courses. Survey questions consisted of Likert-style, multiple-choice, ranking, and open-ended questions that asked students to indicate their level of satisfaction with the active learning techniques. One hundred seventy Medical Science master's students completed the online anatomy course and all seven surveys. Results showed that students were significantly more satisfied with question constructing and jigsaw than with concept mapping and team-learning module. Additionally, historically excluded groups (underrepresented racial minorities) were generally more satisfied with active learning than non-minority groups. Age, gender, and previous experience with anatomy did not influence the level of satisfaction. However, students with a higher-grade point average (GPA), those with only a bachelor's degree, and those with no previous online course experience were more satisfied with active learning than students who had a lower GPA, those holding a graduate/professional degree, and those with previous online course experience. Cumulatively, these findings support the beneficial use of active learning in online anatomy courses.

Introducing dental students to complete denture treatment in times of COVID-19: Students' responses

OBJECTIVES

The COVID-19 pandemic required changes in the complete denture courses to comply with lock-in and social distancing requirements. The objectives were to assess (a) dental students' interest in a required complete denture course and the prosthodontics specialty, (b) how much time students spent on studying background, lab, and clinical content, and (c) how difficult and helpful course components were. Additionally, open-ended responses concerning what the students liked and what they wanted to have changed were analyzed as well.

METHODS

After this "complete denture" course, 81 of 109 students responded to a web-based survey with questions about course content and design. This hybrid course consisted of weekly asynchronous virtual lectures, in-person simulated laboratory (sim lab) exercises, and synchronous virtual workshops.

RESULTS

Exactly 53.7% were much/very much interested in this course, with nobody considering prosthodontics as their specialty. The students studied on average of 79.61 minutes for 1 hour (of background-related lecture, 69.92 minutes for a lab-based lecture, and 77.00 minutes for a clinical-content lecture (p < 0.001). They evaluated clinical content as most difficult, lab content as less difficult, and background material as least difficult (3-point scale with 1 = not at all difficult: means = 1.90/1.85/1.80; p < 0.001). They rated background lectures as least helpful, clinical material as more helpful, and lab content as most helpful (5-point scale with 1 = most helpful: means = 2.33/2.67/2.96; p < 0.001). Open-ended answers showed exceptionally positive responses for content and pedagogy of sim lab and clinical content.

CONCLUSIONS

Gaining a better understanding of students' responses to hybrid "complete denture" courses is critical for optimally teaching this material in times of COVID-19.

Promoting understanding of medical decision-making coding for nurse practitioner students

ABSTRACT

Nurse practitioners (NPs) are often responsible for coding patient encounters for reimbursement. Students should learn the basics of this skill during their educational preparation. On January 1, 2021, the American Medical Association and the Centers for Medicare & Medicaid Services implemented new guidelines to the evaluation and management office appointment documentation and coding. The new medical decision-making (MDM) guidelines created a learning curve for NP students, faculty, and preceptors. An additional obstacle was encountered when on-campus preclinical intensives, which included a coding practice session, were canceled due to the COVID-19 pandemic. The faculty of an NP program identified MDM coding as a difficult concept to teach in an asynchronous learning environment. In response, the faculty developed and implemented synchronous online case study sessions that incorporated active student participation and real-time feedback, thus increasing engagement with peers, faculty, and the MDM concepts. The purpose of this article was to present a synchronous method for teaching MDM coding to NP students, and the outcomes, lessons learned, and implications for nursing education and practice.

Re-thinking the online distance instruction based on students' feedback

During the covid-19 pandemic, schools at all levels were often closed and online distance instruction (ODI) was applied. The main objective of this research was to discover the main didactic features of online distance instruction; and based on the collected data to define didactic recommendations towards improving the quality of the process. Five hypotheses were set that evaluated students' opinions in the areas of teachers' support for learners within ODI, types of sources exploited within ODI, means used for practising and fixing new knowledge within ODI, assessment of learners' performance within ODI, and students' feedback on ODI. In total, 272 respondents from upper secondary and higher education institutions participated in the research. Each respondent described the process of online distance instruction in two courses they selected of 64: (1) in a course that they appreciated, liked, enjoyed, and considered efficient from the point of view of their learning; (2) in a course that caused them discomfort in learning, as it was conducted in a way that did not suit them, and their learning did not bring the expected learning outcomes. Data were collected via a questionnaire; Chí-square test, adjusted residuals, and t test for comparison of means were calculated. Before the research started, teachers were trained in online distance instruction. Therefore, we expected that they will be competent in designing online distance courses and the courses will follow didactic principles. The results discovered significant differences in the frequency of occurrence of observed features in courses that received positive feedback compared to those having negative evaluation. However, some exceptions were detected.
