Using Learning Analytics to Evaluate the Clinical Education Podcast Format

Learning analytics has been rigorously applied to various forms of e-learning, but not to the evaluation of clinical education podcasts. We created a podcast series using the Anchor by Spotify platform, uploading an episode every 2 weeks starting on March 30, 2021. We examined analytics data using a censoring date of November 1, 2022. Based on 29,747 total plays, average audience retention declined 10%/minute until an inflection point at 2.5 minutes, followed by a steady decline of 1.8%/minute. With a maximum episode length of 17 minutes, we did not identify a limit on learner attention for short-form podcasts.
