Adaptive e-learning platforms can improve student performance and engagement in dental education

Assessment of Quality and Reliability of YouTube Videos for Student Learning on Class II Resin Composite Restorations

YouTube has emerged as a popular platform for accessing educational content. However, its effectiveness has been a topic of debate in dental education. This study aimed to analyze the content and quality of YouTube videos focusing on Class II resin composite restorations. The first 100 videos of Class II resin composite information on YouTube were evaluated. The overall quality of the videos was assessed using the video information and quality index (VIQI) and Content Score based on Class II resin composite criteria. Videos with a score of less than the mean were recognized as low-content. No significant differences were observed between high- and low-content videos when the number of views, likes, duration, days since upload, viewing rate, and interaction index were investigated (p>0.05). The number of subscribers revealed a marginally significant difference (p=0.053). The high-content videos demonstrated higher mean values compared to the low-content videos in flow (4.6 vs. 3.8; p=0.0004), accuracy (4.3 vs. 3.3; p<0.0001), value (3.7 vs. 2.9; p=0.002), and precision (4.8 vs. 4.2; p=0.0002). The overall VIQI score was significantly higher (p<0.0001) in high-content videos (Mean 17.4; SD 1.5) compared to the low-content videos (Mean 14.2; SD 2.2). When the Content Score was assessed, high-content videos (Mean 9.9; SD 1.3) revealed a higher score (p<0.0001) than low-content-videos (Mean 4.2; SD 2.3). Most YouTube videos showcasing Class II resin composites serve as effective teaching tools. However, a significant number of videos with low content exist. Therefore, dental students should exercise caution when utilizing YouTube videos for learning purposes.

Contemporary educational methods in periodontology

AIM

The 1st European Workshop on Periodontal Education in 2009 made recommendations regarding the scope of periodontal education at undergraduate (UG), postgraduate (PG) and continuing professional development (CPD) levels, defining competencies and learning outcomes that were instrumental at the time in helping to define periodontal teaching curricula. The 19th European Workshop on Periodontology and 2nd European Consensus Workshop on Education in Periodontology (Education in Periodontology in Europe) was held in 2023 to identify changes and future developments in periodontal education (including those informed by the COVID-19 pandemic) and embracing methods and formats of periodontal teaching and training. The aim of this review was to assess current knowledge regarding education methods in periodontology, including traditional face-to-face (F2F) teaching and the move to student-centred methods, virtual learning methods and use of digital technology, as well as blended teaching and learning (including teaching delivery and assessment) at UG, PG and CPD levels.

MATERIALS AND METHODS

Systematic searches were conducted to identify relevant studies from the literature. Data were extracted and descriptive summaries collated.

RESULTS

The pandemic was a major disruptor of traditional F2F teaching but provided opportunities for rapid implementation of alternative and supplementary teaching methods. Although online learning has become an integral part of periodontal education, teachers and learners alike favour some form of F2F teaching. Blended teaching and learning are feasible in many areas of periodontal education, both for knowledge and skills acquisition as well as in assessment. Student-centred methods and blended approaches such as the flipped classroom seem highly effective, and online/virtual classrooms with both synchronous and asynchronous lectures are highly valued. Learning with haptic methods and virtual reality (VR) enhances the educational experience, especially when VR is integrated with traditional methods. The quality of the teacher continues to be decisive for the best knowledge transfer in all its forms.

CONCLUSIONS

Live F2F teaching continues to be highly trusted; however, all types of student-centred and interactive forms of knowledge transfer are embraced as enhancements. While digital methods offer innovation in education, blended approaches integrating both virtual and traditional methods appear optimal to maximize the achievement of learning outcomes. All areas of periodontal education (UG, PG and CPD) can benefit from such approaches; however, more research is needed to evaluate their benefits, both for knowledge transfer and skills development, as well as in assessment.

Impact of teaching modality on soft skill development: Oral health literacy awareness skills assessed using standardized patient experiences

OBJECTIVES

Health literacy awareness is a crucial skill for health professionals, yet training may be lacking. Didactic lectures may improve health literacy awareness in future health professionals, however, compressed curricula may lead educators to consider the incorporation of eLearning into the delivery of health literacy education. E-modules have been shown to engage learners, yet little is known about their effectiveness in instilling behavioral change in learners' clinical communication skills. This study aimed to shed light on the impact of learning modality on dental students' ability to learn and translate soft skills into clinical settings.

METHODS

An e-module on health literacy awareness was created by the researchers with an equivalent lecture developed. Fifty-six dental students were randomly assigned to a control or intervention cohort (lecture or e-module) and all cohorts participated in standardized patient experiences to be assessed in a simulated but authentic patient care scenario. Pre- and post-intervention scores, simulation scores, and learner reflections were compared.

RESULTS

Fifty-six students participated in the study. Post-intervention health literacy awareness knowledge increased for both intervention cohorts. In clinical simulation, intervention cohorts scored significantly higher on nearly all variables, with the lecture cohort scoring consistently better than e-learners.

CONCLUSION

Both lecture and e-learning are effective learning modalities for promoting health literacy awareness, but dental students learning the subject via lecture may translate certain newly acquired soft skills more effectively in clinical scenarios.

An analytical model of college students' self-assessed satisfaction with the effectiveness of online learning: a structural equation model integrating LICE and S-O-R models

Background

Nowadays, e-learning significantly affects college students' academic life. This study aims to examine the factors that influence college students' satisfaction with online learning outcomes.

Method

The study population consisted of undergraduate students from Dalian Medical University, with a total of 715 college students participating in the study. Out of these participants, 602 valid questionnaires were obtained. Demographic data was analyzed using SPSS.22, and the data was cleaned and prepared for testing the research hypotheses. The proposed research framework was examined using structural equation modeling (SEM) through Smart-PLS 3.0.

Results

The results of the study showed that student satisfaction with learning outcomes was positively correlated with several factors: quality of teacher instruction (β = 0.100, p < 0.0001), quality of e-learning platforms (β = 0.059, p < 0.0001), individual learner factors such as learning motivation (β = 0.112, p < 0.001), and e-learning environment (β = 0.469, p < 0.001). Additionally, self-learning efficacy (β = 0.081, p < 0.0001), learning strategies (β = 0.031, p < 0.001), and learning motivation (β = 0.039, p < 0.001) were found to have mediating effects.

Conclusion

Understanding the satisfaction of college students with the effect of e-learning holds great significance in coping with teaching methods in unexpected situations. It enables adjustments to teaching strategies, improvements to learning platforms, and mobilization of students' motivation. Thus, it serves as a valuable reference in addressing unexpected teaching scenarios.

Effectiveness of E-learning on clinical application of dental injection anatomy via simulation manikins

PURPOSE

E-learning is frequently integrated into dental education, yet little is known on the effectiveness of e-learning in both instilling foundational knowledge and facilitating translation of newly acquired knowledge and skill into clinical application. The objective of this study was to investigate the impact of learning modality on acquisition of knowledge and translation to clinical skill using objective feedback from oral anesthesia manikins and subjects' self-reported confidence scores.

METHODS

This mixed-method study involved first year dental students (n = 52) who volunteered to participate in a learning intervention, simulation exercise, and survey in 2022. Students were randomly assigned to lecture (n = 26) or e-learning (n = 26) cohorts and then participated in the intervention, postintervention assessment, and a simulation to evaluate correct approaches for each dental block and attempts to success.

RESULTS

All subjects scored significantly higher on post-intervention assessment compared to pre-intervention assessment (8.2 vs. 5.9; p < 0.0001) with no significant differences between intervention groups when comparing preintervention and postintervention scores. Furthermore, there were no significant differences between the two cohorts when comparing abilities to correctly approach each dental block or attempts to success. Finally, all students reported a significant increase in confidence in most categories following intervention and simulation, with no significant differences between lecture and e-learning cohorts.

CONCLUSION

Our findings suggest students learning via e-learning are equally capable as those learning via lecture at demonstrating newly acquired knowledge and skill in both assessments and clinical simulations. Results support incorporating supplemental e-learning and oral anesthesia manikin exercises for students learning the anatomy of dental injections.

Using Machine Learning in Veterinary Medical Education: An Introduction for Veterinary Medicine Educators

Machine learning (ML) offers potential opportunities to enhance the learning, teaching, and assessments within veterinary medical education including but not limited to assisting with admissions processes as well as student progress evaluations. The purpose of this primer is to assist veterinary educators in appraising and potentially adopting these rapid upcoming advances in data science and technology. In the first section, we introduce ML concepts and highlight similarities/differences between ML and classical statistics. In the second section, we provide a step-by-step worked example using simulated veterinary student data to answer a hypothesis-driven question. Python syntax with explanations is provided within the text to create a random forest ML prediction model, a model composed of decision trees with each decision tree being composed of nodes and leaves. Within each step of the model creation, specific considerations such as how to manage incomplete student records are highlighted when applying ML algorithms within the veterinary education field. The results from the simulated data demonstrate how decisions by the veterinary educator during ML model creation may impact the most important features contributing to the model. These results highlight the need for the veterinary educator to be fully transparent during the creation of ML models and future research is needed to establish guidelines for handling data not missing at random in medical education, and preferred methods for model evaluation.

Virtual Versus Light Microscopy Usage among Students: A Systematic Review and Meta-Analytic Evidence in Medical Education

BACKGROUND

The usage of whole-slide images has recently been gaining a foothold in medical education, training, and diagnosis.

OBJECTIVES

The first objective of the current study was to compare academic performance on virtual microscopy (VM) and light microscopy (LM) for learning pathology, anatomy, and histology in medical and dental students during the COVID-19 period. The second objective was to gather insight into various applications and usage of such technology for medical education.

MATERIALS AND METHODS

Using the keywords "virtual microscopy" or "light microscopy" or "digital microscopy" and "medical" and "dental" students, databases (PubMed, Embase, Scopus, Cochrane, CINAHL, and Google Scholar) were searched. Hand searching and snowballing were also employed for article searching. After extracting the relevant data based on inclusion and execution criteria, the qualitative data were used for the systematic review and quantitative data were used for meta-analysis. The Newcastle Ottawa Scale (NOS) scale was used to assess the quality of the included studies. Additionally, we registered our systematic review protocol in the prospective register of systematic reviews (PROSPERO) with registration number CRD42020205583.

RESULTS

A total of 39 studies met the criteria to be included in the systematic review. Overall, results indicated a preference for this technology and better academic scores. Qualitative analyses reported improved academic scores, ease of use, and enhanced collaboration amongst students as the top advantages, whereas technical issues were a disadvantage. The performance comparison of virtual versus light microscopy meta-analysis included 19 studies. Most (10/39) studies were from medical universities in the USA. VM was mainly used for teaching pathology courses (25/39) at medical schools (30/39). Dental schools (10/39) have also reported using VM for teaching microscopy. The COVID-19 pandemic was responsible for the transition to VM use in 17/39 studies. The pooled effect size of 19 studies significantly demonstrated higher exam performance (SMD: 1.36 [95% CI: 0.75, 1.96], p < 0.001) among the students who used VM for their learning. Students in the VM group demonstrated significantly higher exam performance than LM in pathology (SMD: 0.85 [95% CI: 0.26, 1.44], p < 0.01) and histopathology (SMD: 1.25 [95% CI: 0.71, 1.78], p < 0.001). For histology (SMD: 1.67 [95% CI: -0.05, 3.40], p = 0.06), the result was insignificant. The overall analysis of 15 studies assessing exam performance showed significantly higher performance for both medical (SMD: 1.42 [95% CI: 0.59, 2.25], p < 0.001) and dental students (SMD: 0.58 [95% CI: 0.58, 0.79], p < 0.001).

CONCLUSIONS

The results of qualitative and quantitative analyses show that VM technology and digitization of glass slides enhance the teaching and learning of microscopic aspects of disease. Additionally, the COVID-19 global health crisis has produced many challenges to overcome from a macroscopic to microscopic scale, for which modern virtual technology is the solution. Therefore, medical educators worldwide should incorporate newer teaching technologies in the curriculum for the success of the coming generation of health-care professionals.

Teaching Cellular Architecture: The Global Status of Histology Education

Histology or microanatomy is the science of the structure and function of tissues and organs in metazoic organisms at the cellular level. By definition, histology is dependent on a variety of microscope techniques, usually light or more recently virtual, as well as electron microscopy. Since its inception more than two centuries ago, histology has been an integral component of biomedical education, specifically for medical, dental, and veterinary students. Traditionally, histology has been taught in two sequential phases, first a didactic transfer of information to learners and secondly a laboratory segment in which students develop the skill of analyzing micrographic images. In this chapter, the authors provide an overview of how histology is currently taught in different global regions. This overview also outlines which educational strategies and technologies are used, and how the local and cultural environment influences the histology education of medical and other students in different countries and continents. Also discussed are current trends that change the teaching of this basic science subject.

Dental students' perception of a blended learning approach to clinic orientation

PURPOSE/OBJECTIVES

The pandemic presented a big challenge to dental education: rapid conversion of a hands-on, experiential learning program to a virtual environment. The objectives of this study are to examine the conventional approaches of facilitating the transition from pre-clinic to clinic, to analyze how a blended learning approach including virtual learning modules facilitated this transition, and to assess the benefits of virtual learning in the future of dental school curriculum.

METHODS

Rising third-year dental students in 2020 (n = 134) were engaged in a three-month (from the end of May to the end of August 2020) clinic orientation consisting of virtual didactic and clinic simulated activities. Part I consisted of didactic courses presented virtually. Part II consisted of simulated clinical activities for operative and radiology along with 3-week virtual treatment planning (TP) sessions with quizzes for each week. Part III consisted of clinical assisting and shadowing activities in the clinic on restorative procedures and TP sessions with senior students. Surveys were administered before and after each part of the orientation program.

RESULTS

Data confirmed that 1) virtually-delivered didactic materials increased students' knowledge in learning relevant key topics of clinic transition and 2) virtual TP sessions increased students' perceived confidence and knowledge in assessment and TP.

CONCLUSION

Despite challenges faced during school closure, most dental students positively valued the virtual orientation methods of learning. Integrating a virtual mode of didactic can serve as a new methodology of the dental school curriculum in preparation for the clinic.

Novel and Innovative Approaches to Teaching Human Anatomy Classes in an Online Environment During a Pandemic

In view of the current situation with a worldwide pandemic, the use of online teaching has become critical. This is difficult in the context of human anatomy, a subject contingent primarily on the use of human cadaveric tissues for learning through face-to-face practical laboratory sessions. Although anatomy has been taught using online resources including 3D models and anatomy applications, feedback from students and academic staff does not support the replacement of face-to-face teaching. At Charles Sturt University, we were obligated to cancel all classes on-campus in 2020 due to the COVID-19 pandemic. We ran exclusive online anatomy practical classes replacing classes usually run on campus. We designed an alternative program that consisted of twenty pre-recorded videos that were prepared in the anatomy laboratory using cadaveric tissues, and then discussed in live (and interactive) tutorials. Furthermore, innovative approaches to learning were shown and encouraged by the lecturer. Student survey responses indicated a positive response to both the anatomical videos and the innovative learning approaches. The results obtained by students showed a statistically significant increase in high distinctions and marked decrease in the amount of fail grades, compared with the previous three years (not online). The use of these videos and the encouragement of innovative learning approaches was a novel experience that will add valuable experiences for improved practice in online anatomy teaching. We propose that online anatomy videos of cadavers combined with innovative approaches are an efficient and engaging approach to replace face-to-face anatomy teaching under the current contexts.
