Self-paced polling increases medical student engagement in recorded lectures and improves examination performance

Engaging preclinical medical students in the curriculum is challenging. To address this challenge, the investigators developed and implemented self-paced polling with recorded lectures, in which students answered audience response questions at their own pace. In 2021, we retrospectively assigned second-year medical students (N = 165) as Active or Inactive based on their answered polling questions. We subdivided the Active group into two groups, a Live group who predominantly responded to polling in live classes and a Self-paced group who predominantly used polling with recorded lectures. Outcomes were academic performance on customized National Board of Medical Examiners (NBME) examinations and engagement. Compared with the Inactive group, the Self-paced group performed better on the customized NBME examination after extensive self-paced polling. Students answered a significantly larger proportion of questions correctly in self-paced polling compared with live polling. Students who used self-paced polling reported a positive experience and indicated they had emotional, behavioral, or cognitive engagement with the curriculum. This study introduces self-paced polling with recorded lectures, which medical educators can potentially use to enhance student engagement and academic performance.NEW & NOTEWORTHY More medical students utilize recorded lectures than live lectures. Self-paced polling questions allow students to participate while watching recorded lectures. Second-year medical students performed significantly better on examination after actively using the self-paced polling compared with inactive students. They also reported emotional, behavioral, and cognitive engagement with the course material while using the self-paced polling.
