Optimal Video Length for Student Engagement? Never More than 6 Minutes

How long should your lecture video on edX or any Open edX platform be?

Never longer than six minutes. After this time, the attention dramatically drops, as shown in the graphic above.

Unsurprisingly, students engaged more with shorter videos.

All of it is shown by research from Philip J. Guo, now a professor of Computer Science at UC San Diego, after considering five million watching sessions.

Interestingly, pursuing a certificate doesn’t mean that the learner will dedicate more time to watching video.

Anant Agarwal, CEO at edX, talked about these big data and neuroscience discoveries during the last Open edX conference in Madrid, Spain (video below).
