Lacunae regarding dearth of dissection-based teaching during COVID-19 pandemic: how to cope with it?

Doing more with less: Realistic stereoscopic three-dimensional anatomical modeling from smartphone photogrammetry

Traditional teaching methods struggle to convey three-dimensional concepts effectively. While 3D virtual models and virtual reality platforms offer a promising approach to teaching anatomy, their cost and specialized equipment pose limitations, especially in disadvantaged areas. A simpler alternative is to use virtual 3D models displayed on regular screens, but they lack immersion, realism, and stereoscopic vision. To address these challenges, we developed an affordable method utilizing smartphone-based 360° photogrammetry, virtual camera recording, and stereoscopic display (anaglyph or side-by-side technique). In this study, we assessed the feasibility of this method by subjecting it to various specimen types: osteological, soft organ, neuroanatomical, regional dissection, and a dedicated 3D-printed testing phantom. The results demonstrate that the 3D models obtained feature a complete mesh with a high level of detail and a realistic texture. Mesh and texture resolutions were estimated to be approximately 1 and 0.2 mm, respectively. Additionally, stereoscopic animations were both feasible and effective in enhancing depth perception. The simplicity and affordability of this method position it as a technique of choice for creating easily photorealistic anatomical models combined with stereoscopic depth visualization.

The impact of online education during the Covid-19 pandemic on the professional identity formation of medical students: A systematic scoping review

Evolving individual, contextual, organizational, interactional and sociocultural factors have complicated efforts to shape the professional identity formation (PIF) of medical students or how they feel, act and think as professionals. However, an almost exclusive reliance on online learning during the COVID-19 pandemic offers a unique opportunity to study the elemental structures that shape PIF and the environmental factors nurturing it. We propose two independent Systematic Evidence-Based Approach guided systematic scoping reviews (SSR in SEBA)s to map accounts of online learning environment and netiquette that structure online programs. The data accrued was analysed using the clinically evidenced Krishna-Pisupati Model of Professional Identity Formation (KPM) to study the evolving concepts of professional identity. The results of each SSR in SEBA were evaluated separately with the themes and categories identified in the Split Approach combined to create richer and deeper 'themes/categories' using the Jigsaw Perspective. The 'themes/categories' from each review were combined using the Funnelling Process to create domains that guide the discussion. The 'themes/categories' identified from the 141 included full-text articles in the SSR in SEBA of online programs were the content and effects of online programs. The themes/categories identified from the 26 included articles in the SSR in SEBA of netiquette were guidelines, contributing factors, and implications. The Funnelling Process identified online programs (encapsulating the content, approach, structures and the support mechanisms); their effects; and PIF development that framed the domains guiding the discussion. This SSR in SEBA identifies the fundamental elements behind developing PIF including a structured program within a nurturing environment confined with netiquette-guided boundaries akin to a Community of Practice and the elemental aspect of a socialisation process within online programs. These findings ought to be applicable beyond online training and guide the design, support and assessment of efforts to nurture PIF.

Evolving strategies in whirlwind mode: The changing face of anatomy education during Covid-19 pandemic

The Covid-19 pandemic stipulated adoption of unfamiliar strategies for delivering anatomy education in online mode. The factors which determine education strategies are variable across geographical regions. It was perceived that an overview of education strategies around the globe would be useful for anatomists. Hence this narrative review was undertaken to collate observations from different geographical regions pertaining to education strategies adopted during the pandemic. Data relevant to the topic of study were extracted from 12 articles that were selected from an initial pool of 317 articles based on search criteria set for the review. Subtle differences in core education strategies implied that baseline response from anatomists was similar across regions. It was evident that online digital tools were key elements of education strategies adopted by educators for delivering online anatomy classes across the globe. Interestingly, a considerable gap in terms of number and variety of online tools used for anatomy education (those requiring commercial purchase) was noted between economically developed and developing regions. This may have an impact on learning outcome for students and may even lead to variations in anatomical knowledge by regions. It was observed that offline human dissection sessions were incorporated into online practical classes in one region as positive cases showed a declining trend. This positive development is worth emulating elsewhere based on cautious assessment of prevailing situation. From a broad perspective timely introduction of education strategies ensured delivery of anatomy education during the pandemic and gave an evolved outlook to the fabric of anatomy education.

The Effect of Distance Education Conducted during the COVID-19 Pandemic Period on the Psychomotor Skill Development of a Dental School Students

Purpose

This study compared the development of face-to-face (F2F) psychomotor skills vs. a modified online dental anatomy course during the COVID-19 pandemic.

Methods

The 9-HPT is regularly applied for the students' psychomotor skill assessment in the Faculty of Dentistry of Süleyman Demirel University. In the 2020-21 academic year, 92.2% of students who took the dental anatomy course in distance education voluntarily participated in this study (observation group). These data were compared with 34.6% of students who applied for 9-HPT in 2019-2020 in F2F education (control group). The Mann–Whitney U test and t-test were used for comparison. The significance level was taken as p < 0.05.

Results

Based on the dominant hand 9-HPT score, a positive change occurred in 81.8% of the F2F and 61.6% of the online education students. Based on both dominant and nondominant hand 9-HPT scores, a statistically significant difference between the change in scores according to the fall/spring term measurements was observed in both F2F and distance education (p < 0.001). However, the F2F-educated group students showed better psychomotor skill development than those exposed to the online-educated group in 9-HPT. The results showed statistical significance for both dominant and nondominant hands (p < 0.001).

Conclusion

The F2F education is the gold standard in psychomotor skill training; however, in cases where this approach cannot be realized, practical training protocols modified for online training may contribute to the motor development of students.
