Can Online Teaching of Radiographic Anatomy Replace Conventional On-Site Teaching? A Randomized Controlled Study.

The study investigates the effectiveness of online learning compared to conventional classroom-based teaching in the area of radiographic anatomy or radio-anatomy. The findings suggest that the online method can be a viable alternative to traditional teaching methods with no significant differences in student performance between the two approaches.

Research Objectives and Methods

• The primary purpose of the study was to evaluate the possible interchangeability of online radio-anatomy teaching with traditional classroom-based teaching, by comparing the performance of veterinary students taught using these different methods.
• Three teaching strategies were compared: online learning only, online learning incorporating the use of specimen equine bones, and traditional classroom learning also using specimen equine bones. The subjects for the study were a cohort of 83 learners.
• The study employed pre-test and post-test methods to gauge the students’ knowledge in radio-anatomy and mental rotation. The aim was to assess any possible improvements in performance after the teaching interventions.

Key Findings

• The study found comparable baseline scores across the groups on the pre-test assessments. The scores significantly improved across all groups after the teaching intervention, indicating effectiveness in knowledge acquisition regardless of the teaching methodology.
• The scores, post-teaching, demonstrated no significant differences between the three groups. This suggests that online teaching of radiographic anatomy could be used interchangeably with conventional methods.
• Gender influenced mental rotation scores with men scoring significantly higher than women both in the pre-test and post-test. However, this gender effect wasn’t observed in terms of radio-anatomy knowledge, which remained consistent across all groups.

Implications

• The findings of the study suggest that online resources can be successfully implemented for teaching radio-anatomy. Importantly, the study provides evidence that online teaching can potentially replace traditional classroom teaching without compromising the learning outcomes, which becomes highly significant in extraordinary situations like the COVID-19 pandemic, which mandated a rapid shift to online teaching methods.
• The study also provides implications for the broader context of medical education, validating the effectiveness and utility of online learning.
