Analysis of different factors on dental students' perception of a flipped classroom model: A 6-year follow-up study

To evaluate different factors affecting two different cohorts of dental students' perceptions with the flipped classroom (FC) model in a preclinical dental course over six years.

In 2016 (cohort #1) and 2022 (cohort #2), second-year dental students participated in FC model in a preclinical dental course consisting of pre-class recorded videos and lectures along with classroom interactive exercises. Students then completed an anonymous pen-and-paper survey evaluating three factors influencing students' overall study experience with the FC model. Survey responses from cohort #1 and cohort #2 were compared to assess the effect of generation, student demographics and COVID-19 pandemic on students' perceptions.

When asked to rate the FC experience out of 5, the mean ratings of cohort #1 and cohort #2 were 4.3 (±0.9) and 4.0 (±0.8), respectively. Cohort #2 preferred viewing slides and videos prior to class and had a higher agreement that pre-class course materials were beneficial to class preparation. Conversely, cohort #1 had a higher agreement that in-class discussion and exercises helped them to learn course content. From cohort #2, 88.6% of males and 71.6% of females preferred the FC approach over traditional lecture.

Both cohorts reported positively with the FC model of teaching. Cohort #2 had higher positive reports with the pre-class work and cohort #1 had a higher positive report with in-class work. Course design should reflect the students' points of view and learning perspectives with careful consideration of the student population in the classroom.
