- Video length can significantly affect engagement. Shorter videos are much more engaging to learners. Invest in pre-production lesson planning to segment videos into chunks that are no longer than 6-7 minutes in length, if possible.
- Videos that intersperse an instructor’s talking head (where the instructor looks directly into the camera) with slides are more engaging than slides alone. Invest in post-production editing to display the instructor’s head at opportune times in the video. Avoid displaying the instructor’s head for the entire video unless there are no slides that accompany the presentation.
- Videos produced with a more personal feel could be more engaging than studio recordings. In videos where there are few slides and more video of the instructor’s talking head, try filming in an informal setting related to the subject matter of the video (i.e. office, lab, in the field, etc.) instead of a formal production studio.
- For step-by-step problem solving walkthroughs, Khan Academy-style tablet drawing tutorials are more engaging than slides alone.
- Videos where instructors speak fairly fast and with high enthusiasm are more engaging (especially for instructors who's native language is the same as the language of the course). The pace can be accelerated compared to conventional face-to-face lectures. This also has the indirect positive effect of keeping video length shorter (see point 1 above). During post production, consider removing some speech pauses including “umms” and “ahhs” if they are present too frequently.
- Learners engage differently with lecture-style conceptual videos compared to step-by-step walkthrough procedural tutorial videos. For lectures-style, focus more on the providing a good first-watch experience from beginning to end. For step-by-step walkthrough tutorials, make it easy to rewatch and/or skim the video. For example, clearly number the “step” in the process as the process develops so that students can easily orient themselves in the tutorial video when they re-watch relevant parts.
