Metaverse-powered basic sciences medical education: bridging the gaps for lower middle-income countries

BACKGROUND

Traditional medical education often lacks contextual experience, hindering students' ability to effectively apply theoretical knowledge in real-world scenarios. The integration of the metaverse into medical education holds great enormous promise for addressing educational disparities, particularly in lower-middle-income countries (LMICs) accompanied by rapid technological advancements. This commentary paper aimed to address the potential of the metaverse in enhancing basic sciences education within the constraints faced by universities in LMICs. We also addressed learning design challenges by proposing fundamental design elements and a suggested conceptual framework for developing metaverse-based teaching methods.The goal is to assist educators and medical practitioners in comprehensivley understanding key factors in immersive teaching and learning.

DISCUSSION

By immersing medical students in virtual scenarios mimicking real medical settings and patient interactions, the metaverse enables practice in clinical decision-making, interpersonal skills, and exposure to complex medical situations in a controlled environment. These simulations can be customized to reflect local healthcare challenges, preparing medical students to tackle specific community needs. Various disciplines, including anatomy, physiology, pharmacy, dentistry, and pathology, have begun leveraging the metaverse to offer immersive learning experiences, foster interdisciplinary collaborations, and facilitate authentic assessments. However, financial constraints pose a significant barrier to widespread adoption, particularly in resource-limited settings like LMICs. Addressing these challenges is crucial to realizing the full potential of metaverse technology in medical education.

CONCLUSION

The metaverse offers a promising solution for enhancing medical education by providing immersive, context-rich learning experiences. This paper proposes a conceptual framework and fundamental design elements to aid faculty educators and medical practitioners in effectively incorporating metaverse technology into their teaching methods, thus improving educational outcomes in LMICs.

Investigation of factors that influence the relationship between mental rotation ability and anatomy learning

BACKGROUND

Mental rotation is a cognitive process that involves the rotation of a mental representation of an object. This ability is important for medical students in studying anatomy as this subject requires the understanding of positional relations between organs.

OBJECTIVES

To find the effect of video learning of anatomy, training, gender, and type of practical exam on mental rotation ability. Also, to find correlation between mental rotation and anatomy scores.

METHODS

Two groups were recruited: group A studied practical anatomy online using videos due to the COVID-19 pandemic lockdown; group B studied anatomy labs on-campus on plastic models. Both groups underwent a mental rotation test. Group A took labs on-campus during their second year and this was considered a training course for their mental rotation ability. Both groups, then, took a second mental rotation test. Group A was finally given a practical anatomy exam using plastic models.

RESULTS

Males scored higher than females, though not significantly. The intervention course produced no significant change in mental rotation score of group A. Mental rotation score was correlated more with the theoretical anatomy exams than the MCQ-based practical exam, for both groups. For group A, mental rotation was better correlated with the model-based than the MCQ-based practical exam, especially the post-training score.

CONCLUSION

For students to take full advantage of their mental rotation ability, not only their practical anatomy sessions but their practical anatomy exams should be on anatomical specimens and not just videos or images.

The relationship between visual memory and spatial intelligence with students' academic achievement in anatomy

INTRODUCTION

Academic achievement is influenced by various factors. Spatial intelligence and visual memory are among the factors that seem to be related to learning anatomy. The aim of this study was to investigate the relationship between visual memory and spatial intelligence with students' academic achievement in anatomy.

METHODS

The present study is a descriptive cross-sectional study. All medical and dental students who had chosen anatomy courses (Semester 3 medicine and 2 dentistry) were the target population (n=240). The study tools were Jean-Louis Sellier 's visual memory test to determine visual memory and ten questions from Gardner Spatial Intelligence Questionnaire were employed to assess spatial intelligence. The tests were performed at the beginning of the semester and its relationship with the academic achievement scores of the anatomy course was examined. Data were analyzed by descriptive statistics, independent t-test, Pearson correlation and multiple linear regression.

RESULTS

Data of 148 medical students and 85 dental students were analyzed. The mean score of visual memory in medical students (17.1±5.3) was significantly higher than dental students (14.3±4.6) (P-value <0.001). But the mean score of spatial intelligence (31.5±5.9) was not significantly different between medical and dental students (31.9±4.9) (P-value=0.56). Pearson correlation coefficient showed that in medical students there was a direct relationship between visual memory score and spatial intelligence score with scores of anatomy courses (P-value<0.05). Moreover, in dental students, there was a direct relationship between the score of anatomical sciences with the score of visual memory (P-value=0.01) and the score of spatial intelligence (P-value=0.003).

CONCLUSION

The results of this study showed that there is a significant relationship between spatial intelligence and visual memory with learning anatomy and planning to enhance these characteristics can be fruitful in students. It is suggested that Visual memory and spatial intelligence should be considered for student admission, especially in the fields of medicine and dentistry.

Evaluating the integration of body donor imaging into anatomical dissection using augmented reality

Augmented reality (AR) has recently been utilized as an integrative teaching tool in medical curricula given its ability to view virtual objects while interacting with the physical environment. The evidence for AR in medical training, however, is limited. For this reason, the purpose of this mixed method study was to evaluate the implementation of overlaying donor-specific diagnostic imaging (DSDI) onto corresponding body donors in a fourth-year, dissection-based, medical elective course entitled anatomy for surgeons (AFS). Students registered in AFS course were separated into groups, receiving either DSDI displayed on Microsoft HoloLens AR head-mounted display (n = 12) or DSDI displayed on iPad (n = 15). To test for the change in spatial ability, students completed an anatomical mental rotation test (AMRT) prior to and following the AFS course. Students also participated in a focus group discussion and completed a survey at the end of AFS, analyzed through thematic triangulation and an unpaired, Mann Whitney U test respectively, both addressing dissection experience, DSDI relevancy to dissection, and use of AR in anatomical education. Although statistically significant differences were not found when comparing student group AMRT scores, survey and discussion data suggest that the HoloLens had improved the students' understanding of, and their spatial orientation of, anatomical relationships. Trunk dissection quality grades were significantly higher with students using the HoloLens. Although students mentioned difficulties with HoloLens software, with faculty assistance, training, and enhanced software development, there is potential for this AR tool to contribute to improved dissection quality and an immersive learning experience.

Awareness of Universal Design for Learning among anatomy educators in higher level institutions in the Republic of Ireland and United Kingdom

There is an increasing need to facilitate enhanced student engagement in anatomy education. Higher education students differ in academic preferences and abilities and so, not all teaching strategies suit all students. Therefore, it is suggested that curricula design and delivery adapt to sustain learner engagement. Enhanced learner engagement is a fundamental feature of Universal Design for Learning (UDL). The aim of this study is to determine if anatomy educators in the Republic of Ireland (ROI) and United Kingdom (UK) are aware of UDL and to assess if, and to what extent, it has been implemented in the design and delivery of anatomy curricula for healthcare students. An anonymous online questionnaire was administered to anatomy educators in higher level institutions in the ROI and UK. Inductive content analysis was used to identify the impact of UDL on student learning, engagement, and motivation, as perceived by the participants. The response rate was 23% (n = 61). Nineteen participants stated they knew of UDL. Of these, 15 had utilized UDL in their teaching of anatomy. Analysis indicated that the perception of UDL was mixed. However, the majority of responses relating to UDL were positive. The majority of the respondents were unaware of UDL but identified the frameworks' checkpoints within their curriculum, suggesting they have unknowingly incorporated elements of UDL in their curriculum design and delivery. There is a lack of information on the benefits of explicit utilization of UDL for engagement and motivation to learn anatomy in healthcare programs in the ROI and UK.

Evaluation of an Augmented Reality Application for Learning Neuroanatomy in Psychology

Neuroanatomy is difficult for psychology students because of spatial visualization and the relationship among brain structures. Some technologies have been implemented to facilitate the learning of anatomy using three-dimensional (3D) visualization of anatomy contents. Augmented reality (AR) is a promising technology in this field. A mobile AR application to provide the visualization of morphological and functional information of the brain was developed. A sample of 67 students of neuropsychology completed tests for visuospatial ability, anatomical knowledge, learning goals, and experience with technologies. Subsequently, they performed a learning activity using one of the visualization methods considered: a 3D method using the AR application and a two-dimensional (2D) method using a textbook to color, followed by questions concerning their satisfaction and knowledge. After using the alternative method, the students expressed their preference. The two methods improved knowledge equally, but the 3D method obtained higher satisfaction scores and was more preferred by students. The 3D method was also more preferred by the students who used this method during the activity. After controlling for the method used in the activity, associations were found between the preference of the 3D method because of its usability and experience with technologies. These results found that the AR application was highly valued by students to learn and was as effective as the textbook for this purpose.

Development and Assessment of an Integrated Anatomy Mobile App

INTRODUCTION

Curricular hours for anatomical sub-disciplines (gross anatomy, embryology, histology, and neuroanatomy) continue to decline, while medical schools are simultaneously transitioning to systems-based, vertically integrated curricula. This requires students to learn and integrate all basic science content for a learning block prior to the summative assessment. Currently, no educational technology resource exists that integrates the four anatomical sub-disciplines into a single resource to supplement integrated curricula. The objective of this study was to assess a novel integrated anatomical sciences mobile app for medical students.

MATERIALS AND METHODS

The 4natomy mobile app was developed to integrate the four sub-disciplines for a single topic, the spinal cord. The app was distributed to first-year medical students during the neurological disorders learning. Following the learning block, assessment of the student acceptance and experience with the app was conducted through a technology acceptance model (TAM) framework survey.

RESULTS

The results indicated that students found the app to be useful (p < 0.001) and easy to use (p < 0.05), predicting continued future usage of the app. Students requested expanded anatomy content for the entire learning block, as well as more clinical correlations, videos, and animations.

CONCLUSIONS

The integrated anatomy mobile app developed in this study was useful and easy to use, indicating continued use within an integrated medical curriculum. This was the first study to utilize the TAM as a conceptual framework for technology assessment in medical education, suggesting that future studies that develop new technologies should adapt the TAM for user testing.
