Comparative study of self-directed learning and traditional teaching method in understanding cardio- respiratory physiology among medical undergraduates

Abstract

Introduction and Aim: Active and learner centred learning methods specially, self-directed learning is considered to be an important method of blended learning approach of imparting knowledge among under graduate medical students in new curriculum through integrated approach. The aim of the study is to analyse the impact and benefits of self-directed learning sessions for understanding cardio- respiratory physiology among phase one MBBS students. Design and Methods: This cross-sectional study was conducted among 250 students of Phase I MBBS for CVS and RS modules.  Two groups of students were made Group A (n=125) was administered with self- directed learning sessions, while group B (n=125) was administered with normal didactic lecture session for the same topics. Following each session an objective assessment was conducted for all the topics covered in SDL and lecture sessions and the results were assessed and compared. Results: The maximum marks secured in objective assessment by Group A students post self-directed learning sessions for both cardiovascular and respiratory physiology modules were 31.2% (39/125) and 32.8% (41/125); while moderate marks were secured by 47.2% (59/125) and 48% (60/125). For assessment conducted after lecture sessions for both cardiovascular and respiratory physiology module, maximum marks were obtained by 25.6% (32/125) and 24% (30/125); while moderate marks were obtained by 21.6% (27/125) and 23.5% (29/125) respectively. Significant difference was found in the p values of marks for both modules(n=0.009) (n=0.008). The internal assessment scores showed considerable difference in the maximum marks obtained by students attending SDL sessions (80-89%) as compared to didactic learning sessions (70–79%) with p value = 0.0190, 0.01179 and 0.0192, a0.01184, respectively for both modules. Conclusion: Self-directed learning method seems to be more effective way of delivering the concept as compared to traditional lecture sessions.
