There are a number of factors that contribute to the design and development of effective learning videos. In keeping with the cognitive theories outlined above, video text, images, animation, and audio content should be designed to minimize cognitive load:
- Segment (chunk) content carefully.
- When providing tutorials, use a first-person rather than a third-person perspective.
- Provide both spoken narration and related imagery/action. (However, for accessibility provide a means for the learner to access the text of the narration.) Use a conversational tone in narration.
- Provide advance organizers and other visual and verbal cues to assist learners in schema creation.
- Associate content with emotion (positive or negative) to increase motivation and retention.
- Give the user control by including interactive tools for searching and navigation.
