WestJEM article, Does the Podcast Video Playback Speed Affect Comprehension for Novel Curriculum Delivery? A Randomized Trial, by Kristine Song, MD, PGY-1, Amit Chakraborty, MD, Matthew Dawson, MD, Adam Dugan, MS, Brian Adkins, MD, Christopher Doty, MD. suggests that, unlike previously published studies that showed subjective improvement in performance with sped-up video-recorded lectures compared to normal speed, objective performance may be worse.
Medical education is a rapidly evolving field that has been using new technology to improve how medical students learn. One of the recent implementations in medical education is the recording of lectures for the purpose of playback at various speeds. Though previous studies done via surveys have shown a subjective increase in the rate of knowledge acquisition when learning from sped-up lectures, no quantitative studies have measured information retention. The purpose of this study was to compare mean test scores on written assessments to objectively determine if watching a video of a recorded lecture at 1.5x speed was significantly different than 1.0x speed for the immediate retention of novel material.
