Leveraging Technology and Gamification to Engage Learners in a Microbiology Curriculum in Undergraduate Medical...

Microbiology is a critical and expansive topic that many medical schools' curriculum must teach in a constrained time frame. We implemented a microbiology question bank smart phone app enhanced with game elements and clinical pearls during a microbiology course for first-year medical students. We hypothesized that these enhancements and clinical pearls would engage the students meaningfully and increase their knowledge base.

Though use was optional, students' game play was recorded through the app, which was compared to test grades retrospectively. A player efficiency rating (PER) was calculated as a function of question response, accuracy, and engagement. Students were separated into tertiles of PER and median exam grades were compared using a non-parametric Kruskal-Wallis (KW) test. An anonymous satisfaction and usability feedback survey was also administered.

One hundred eighty-one of the 189 students (96%) answered at least one question, and 165 (87%) completed all 56 questions. The average PER was 84.75. We received feedback surveys from 61 (34%) students in the course, with positive responses regarding the perceived impact on learning microbiology. The KW test found a positive correlation for median exam scores of the player groups when divided into tertiles by PER (p = 0.0002).

We leveraged gamification and clinical pearls to design a supplemental microbiology question bank. We found high engagement overall and higher class exam scores associated with greater use of the question bank.
