Effectiveness of flipped classroom model in teaching histology for first-year MBBS students based on competency-based blended learning: An interventional study

BACKGROUND: With recent changes in the curriculum of bachelor of medicine and bachelor of surgery (MBBS) course to meet the global trends and to fulfill the standards expected from an Indian medical graduate, introduction of newer teaching methodologies becomes mandatory. The usage of flipped classroom (FCR) in medical education has always been rewarding. This study was to evaluate the effectiveness of FCR as a teaching method in comparison with traditional lectures in histology sessions in Sri Ramaswamy Memorial (SRM) Medical College Hospital and Research Centre, Chennai, Tamil Nadu, India. MATERIALS AND METHODS: This interventional study was conducted among the 1(st) year MBBS students in SRM Medical College Hospital and Research Centre for a period of 1 year (2018–2019 academic year). The histology sessions were taught using both traditional lectures and FCR methodology. Pre- and posttests were conducted for each traditional and FCR session with ten multiple-choice questions pertaining to that topic. Students' performance was assessed by paired t-test (for pre- and posttest comparisons) and independent t-test (for traditional and FCR posttest mark comparison) using SPSS software version 26. A feedback survey based on Likert scale was also conducted on the students and was analyzed. P < 0.05 was considered statistically significant. RESULTS: Posttest marks had statistically significantly improved when compared to pretest marks (P < 0.0001) in both traditional and FCR teaching methods. Comparison of posttest marks showed statistically significantly higher marks in FCR when compared to traditional teaching (P < 0.0001). Similarly, students’ feedback survey showed that FCR benefitted the students in achieving the competency required. CONCLUSION: FCR methodology of teaching histology had a very impressive outcome and the students' perception was very positive.
