RESUMEN
Introduction Team-based learning (TBL) is an active and structured learning process. This study was undertaken to develop interest among the students over the subject and to analyze the academic performance over routine conventional lecture method of teaching. This was a comparative study organized to know the effectiveness of TBL over conventional didactic lecture (CDL) and also to assess the student's perception towards TBL. Methods This was an interventional study where second-year MBBS students took part. Students were divided into two groups and the same topic was discussed by using two different teaching-learning methods. Similar sessions were conducted with crossing over of groups for four different topics and assessments were done after each session simultaneously for both the groups and the results were analyzed. Results Assessment of each session has been counted and the mean marks with standard deviation have been tabulated for both groups A & B. The results were statistically significant for the TBL group. Students' perception was also evaluated by using 5-point Likert scale for both the teaching methods, which revealed statistically significant score for TBL over CDL with the a p-value of 0.001. Conclusion Overall, TBL was a good teaching-learning method according to the students' performance and perception. Interactive innovative and small-group sessions can be an effective tool to overcome the limitation of conventional method.
