Comparative Analysis of Multidimensional Learning Tools in Anatomy: A Randomized Control Trial

Introduction: Anatomy teaching has traditionally been based on dissection. However, reduced hours in total and laboratory hours in gross anatomy along with a dearth of cadavers have ensued the search for a less time-consuming tool. Materials and Methods: The study was conducted in the Department of Anatomy in Sheikh Bhikhari Medical College, Hazaribag. A total of 282 medical students were taught gross anatomy, using three different learning modalities: dissection ( n = 95), plastic models ( n = 94), and three-dimensional (3D) anatomy software ( n = 93). The knowledge of the students was examined by 100 multiple-choice question (MCQ) and tag questions followed by an evaluation questionnaire. Results: When performance is considered, the dissection and 3D group performed better than the plastic models group in total, MCQs, and tag questions. In the evaluation questionnaire, dissection performed better than the other two modalities. Moreover, dissection and 3D software emerged as superior to the plastic models group. Statistical Analysis: All data were analyzed using the one-way ANOVA and t -test. Group-based analysis by ANOVA and gender-based analysis were done by Student’s t -test. A comparison of students’ perceptions was done by Kruskal–Wallis H -test. Conclusion: Dissection remains a favorite with students and accomplishes a significantly higher attainment of knowledge. Plastic models are less effective but are a valuable tool in preparation for cadaveric laboratories.
