Optimal Video Length for Student Engagement

The optimal video length is 6 minutes or shorter — students watched most of the way through these short videos. In fact, the average engagement time of any video maxes out at 6 minutes, regardless of its length. And engagement times decrease as videos lengthen.


Listening to Narratives: An Experimental Examination of Storytelling in the Classroom

Audience members retain more information when it is presented in a narrative style and when it is presented at a normal presentation rate.

A Meta-Analytic Examination of the Instructional Effectiveness of Computer‐Base Simulation Games

A University of Colorado Denver Business School study found those trained on video games do their jobs better, have higher skills and retain information longer than workers learning in less interactive, more passive environments.

The learning benefits of teaching: A retrieval practice hypothesis

Teaching educational materials to others enhances the teacher's own learning of those to‐be‐taught materials, although the underlying mechanisms remain largely unknown. The learning‐by‐teaching benefit is possibly a retrieval benefit.
