Background: Orthopaedic surgery is underrepresented in the United Kingdom medical school curriculum, with an average of less than 3 weeks of exposure over the five-year degree. This study evaluates the effectiveness of high-fidelity virtual reality (VR) and physical model simulation in teaching undergraduate orthopaedic concepts. Methods: A modified randomised crossover trial was used. Forty-nine students were randomly allocated to two groups, with thirty-three finishing the six-week follow-up assessment. All undergraduate medical students were eligible for inclusion. Both groups were given introductory lectures, before completing a pre-test with questions on the principles of fracture fixation and osteotomy. Each group then received a lecture on these topics with the same content, but one was delivered with VR and the other with physical models. Both groups completed the post-course assessments. Knowledge was assessed by way of questionnaire immediately before, immediately after, and six-weeks after. Results: In the VR group, participants improved their post-training score by 192.1% (U=32; p<0.00001). In the physical models group, participants improved their post-training scores by 163.1% (U=8.5; p<0.00001). Overall, there was no statistically significant difference in the total means of post-training test scores between the VR and the physical models study groups (U=260.5; p=0.4354). Conclusion: Both VR and physical models represent valuable educational adjuncts for the undergraduate medical curriculum. Both have demonstrated improvements in immediate and long-term knowledge retention of key orthopaedic concepts.

This paper evaluates the accessibility of selected field and laboratory high school science activities, and provides suggestions for increasing accessibility for students with disabilities. We focused on GLOBE (Global Learning Observations to Benefit the Environment) protocols, specifically the new Seasons and Biomes investigation currently being developed as part of the GLOBE program. Five university students with disabilities majoring in science or technology were recruited to test the GLOBE protocols, and 10 protocols were evaluated for accessibility. Based on our results, we make several suggestions with regards to instructions, equipment, safety, outcomes and activity significance that will increase the accessibility of GLOBE and all K-16 science methods.
