Effectiveness of team-based learning in microbiology: a non-randomized control study.
BACKGROUND
As per the present curriculum in India, pre- and paraclinical subjects are taught away from the clinical setting. Therefore, students fail to connect the subject taught through didactic lectures to the clinical setting. Team-based learning (TBL) can be used in conjunction with lectures to teach applied microbiology. This study aims to evaluate the effectiveness of TBL sessions in conjunction with lectures to enhance learning of applied microbiology, among Indian students.


METHODS
All students enrolled in the study were taught systemic bacteriology through lectures. Of the 88 students, 49 students (study group) attended TBL sessions on the topics of diarrhea, fever of unknown origin, urinary tract infection and 39 students (control group) preferred self-study on the topics without attending the TBL sessions. Students' feedback on their perception on TBL sessions was collected using a questionnaire of 10 items. The performance of both the groups on the pre- and post-test were analyzed using unpaired t-test and analysis of variance (ANOVA). Gender-wise performance within the teams was analyzed by paired t-test using SPSS version 12.


RESULTS
The TBL group outperformed the self-study group on the post-test [F 1 = 5.521, P = 0.021]. Female students as a whole performed better than males on the pre-test, scoring higher within both the TBL and self-study groups. Male students in the TBL group performed significantly better on the post-test than female students who participated in TBL sessions (P = 0.013). Students generally enjoyed and appreciated the TBL sessions.


CONCLUSIONS
TBL sessions can be used judiciously in combination with the lectures to enhance learning of applied microbiology in India. In this study, TBL improved the performance of male students over self-study, but performance for female students following TBL was no better than when they simply studied by themselves.
