Episode notes
Coherence Principle
- Reduce extraneous processing in multimedia lessons by removing irrelevant words and graphics.
- These distractions reduce performance on transfer tests, according to Richard Mayer.
Signaling Principle
- Use signaling to highlight essential material when extraneous information cannot be removed.
- For example, in video lectures, pointing to relevant slide sections connects words and graphics effectively.
Spatial Contiguity Principle
- Integrate text within graphics instead of using captions or legends.
- Placing text next to corresponding graphic elements improves understanding and reduces wasted eye movements.
