- Research question
- What has the theory claimed, what evidence supports its principles, and where should research go next?
- Design
- A theoretical review by the originator of the cognitive theory of multimedia learning.
- What it found
- Restates three assumptions: separate verbal and visual channels, limited capacity in each, and learning as active processing.
- Distinguishes extraneous, essential and generative processing, with design principles aimed at each.
- Notes boundary conditions, such as principles that matter most for learners with less prior knowledge.
- Limitations
- A review by the theory’s author rather than an independent appraisal.
- Much underlying research uses short, system-paced lessons with university students.
- Educational implications
- Remove material that does not serve the explanation, place labels near what they describe, and signal what matters.
- Cognitive Lab interpretation
- Cognitive Lab treats the design principles as well-supported defaults that should be adapted, especially for more expert learners.
