The objective of this study was to evaluate microlearning as a preceptor development method compared to a traditional method of learning. Twenty-five preceptor participants volunteered to engage in a learning intervention about two preceptor development topics. Participants were randomized 1:1 to either a thirty-minute traditional learning experience or a fifteen-minute microlearning experience; participants then crossed over to the other intervention for comparison. Primary outcomes were satisfaction, changes in knowledge, self-efficacy, and perception of behavior, confidence scale, and self-reported frequency of behavior, respectively. One-way repeated measures ANOVA and Wilcoxon paired t-tests were used to analyze knowledge and self-efficacy, and Wilcoxon paired t-tests were utilized to assess satisfaction and perception of behavior. Most participants preferred microlearning over the traditional method (72% vs. 20%,p= 0.007). Free text satisfaction responses were analyzed using inductive coding and thematic analysis. Participants reported that microlearning was more engaging and efficient. There were no significant differences in knowledge, self-efficacy, or perception of behavior between microlearning and the traditional method. Knowledge and self-efficacy scores for each modality increased compared to the baseline. Microlearning shows promise for educating pharmacy preceptors. Further study is needed to confirm the findings and determine optimal delivery approaches.
