Purpose
Traditional lecture sessions are considered the gold standard in higher education. However, a trend towards interactive learning style sessions has been on the rise for improving student critical thinking abilities, engagement, and comprehension of presented materials. Historically, students in optometry programs have perceived histology as unimportant or non-essential, likely due to its low emphasis on the National Board of Examiners in Optometry (NBEO) exam. However, the pathological importance of histology and its relevance to patient care and treatment remains significant.

Methods
Five-hour histology didactic sessions were delivered in the optometry first year program during 2022 in a traditional setting(n=115). In 2023, the five-hour histology didactic sessions incorporated problem-based learning activities to enhance student engagement. A sixth hour was incorporated for team-based-learning activities delivered through Zoom (breakout rooms were utilized for sub-groups of 7-8 students, n=110). The 2024 iteration further incorporated 2 more hours for additional active learning(team-based) assignments(n=117). After groups completed their activities, discussion between a content expert commenced with group designated representatives to discuss why their team chose their answers. A quantitative assessment was given to the students with the same questions used for the 2022-2024 iterations of the course.

Results
Students displayed active participation during active learning portions of the 2023/2024 sessions (n=110, n=117). Qualitative feedback indicated high engagement during active learning components, with students responding positively to these changes. Student evaluations are being analyzed to assess the impact of active learning compared to traditional didactic sessions.

Conclusions
The incorporation of active learning modalities in histology coursework has improved student learning outcomes. Evidence-based active learning strategies in medical education demonstrate significant potential for enhancing students' retention of important course materials and their ability to apply this knowledge in clinical settings. Student performance on histology exam questions will be evaluated to inform and refine future active learning sessions.
