Introduction of Problem Based Learning (PBL) as a Supplementary Tool to Enhance Active Learning in Physiology – A Study in a Medical College of Southern Kolkata

BACKGROUND The motivation to learn begins with a problem. The ideology of problem-based learning (PBL) is to encourage the students to think beyond the books and apply the basic knowledge to various clinical scenarios. Problem based learning has been a concept in existence for decades, yet its implementation in medical education is limited. So the study on PBL was taken up to know analytical skills, comprehensive understanding of disease process and inculcate the practice of self-directed learning in physiology. METHODS This was an educational interventional study carried out on 60 first MBBS students chosen by simple random sampling. Students were further randomly divided into two groups containing 30 students in the control group and 30 students in the study group. Control group was taught by didactic lectures. 10 clinical scenarios were given to study group and discussions were conducted under the moderation of faculties. Objective evaluation was performed using pre-test and post-test examination for both groups. Subjective evaluation of attitude in study group towards PBL was recorded using self-developed questionnaire using Likert’s scale. Data was analysed by using paired students t test. RESULTS The mean pre-PBL (9.83±4.88) and post-PBL scores (15.61 ± 2.99) in study group were significant (p < 0.00001). The comparison of mean scores of postdidactic lectures (12.88 ± 3.13) in control group and post-PBL (15.61 ± 2.99) in study group were significant (p < 0.001). Subjective evaluation using Likert’s scale revealed increased interest in active learning, better confidence, communication, comprehension, and motivation amongst the PBL group. CONCLUSIONS From the results of this study, it can be concluded that problem-based learning is a good supplementary tool in teaching physiology, and it can be included in the regular medical teaching programmes so that the students have a better understanding of the various challenges in the field of medical education and research so that newer strategies for better health care provision can be planned.
