Self-Directed Learning Versus Traditional Teaching in Learning Gross Anatomy Among First-Year Medical Students: A Comparative Study.

Introduction: Gross anatomy is the first subject to be grasped by budding medicos before learning a long series of skills and competencies required to bloom as a physician or surgeon. In recent years, the teaching time for anatomy has been reduced. The number of anatomy teachers is much less in comparison to the increasing number of students. There is also a paradigm shift in medical education; it has become competency-based, learner-centric, and technology-based. So, anatomical education is also shifting to adopt blended learning strategies. Now, the onus of learning lies more with the students, which can be promoted through self-directed learning (SDL). Many first-year medical students are unprepared for SDL and need assistance understanding SDL. Structured SDL can successfully instill the habit of SDL in young medical students, who are supposed to be lifelong learners in their professional careers. The concept of structured SDL under the supervision of teachers is comparatively new in India. Very few studies are there to compare the effectiveness of SDL with those of traditional teaching methods. The present study aimed to evaluate the effectiveness of SDL in learning the gross anatomy of an important viscus, viz., the liver, and to compare it with the effectiveness of the traditional method of teaching by demonstration/prosection.

Methods:  This interventional comparative study was carried out at the department of anatomy of a government medical college in Kolkata, India. Sixty willing first-year undergraduate medical students were included in the study. The students were divided into two batches (Batch A and Batch B) of 30 each. Students of Batch A were taught the viscus (liver) by the traditional method of teaching by demonstration/prosection for one and a half hours. Validated pre-test and post-test questionnaires were administered to evaluate learning outcomes. Students of Batch B had a structured self-directed learning (SDL) session under the supervision of teachers on the same topic, viz., viscus (liver), for one and a half hours. The pre-test and post-test questionnaires were given before and after the SDL sessions to evaluate learning outcomes. The results were statistically analyzed.

Results: It was observed that the mean post-test score after traditional teaching improved significantly compared to the mean pre-test score. Also, the mean post-test score after the SDL session improved significantly compared to the mean pre-test score. It was found that the mean post-test score after exposure to traditional teaching methods was slightly better than the mean post-test scores after exposure to SDL, but this difference was not statistically significant.

Conclusion: It can be inferred that structured SDL under the supervision of teachers was almost as good as the traditional teaching method by demonstration/prosection in learning the gross anatomy of an important viscus, viz., liver. In the context of the reduced number of anatomy teachers and an increasing number of students, this may open up an option of teaching some portion of gross anatomy, like a few viscera, by SDL. However, a more robust study with a larger sample size can be more conclusive.
