Mayer's Principles of Multimedia Learning
Mayer's principles are evidence-based design rules for learning from words and pictures, derived from his Cognitive Theory of Multimedia Learning. The theory assumes separate visual and verbal channels, limited capacity in each, and active processing, and the principles aim to reduce extraneous load, manage essential load and foster generative processing.
When participants seem unmotivated or disengaged
You need to understand what drives adult learners and how to create conditions for genuine engagement and retention.
Whenever a session contains presentation segments, pre-recorded video, e-learning modules or visual materials.
Cut the extraneous
Remove decorative content, tangents and extra text (coherence), and add cues that highlight structure (signaling). Avoid narrating the exact text on a slide (redundancy).
Place words and visuals together
Put labels next to the parts of a diagram (spatial contiguity) and say things while showing them (temporal contiguity).
Manage essential load
Break complex content into learner-paced segments (segmenting), introduce key terms beforehand (pre-training), and explain visuals with speech rather than on-screen text (modality).
Foster generative processing
Use words and pictures together (multimedia), a conversational tone (personalization) and a human voice (voice) to encourage learners to make sense of the material.
Check the presenter's role
A visible talking head does not by itself improve learning (image principle); use presenter presence when it adds gesture or attention cues.
Taps into intrinsic motivation so participants actually want to participate.
Use the principles as a review checklist for slides, videos, e-learning and handouts, and when deciding how a facilitator presents input segments in a live session.
- 1Give participants autonomy over how they engage
- 2Connect content to their real challenges
- 3Build confidence through early wins
- 4Create psychological safety for sharing
- Slide and video design
- E-learning and asynchronous modules
- Pre-reads and handouts
- Online and hybrid presentations
- Dual channels, limited capacity, active processing
- Reduce extraneous processing
- Manage essential processing
- Foster generative processing
- Most evidence comes from short, lab-based lessons with novice learners; effects can shrink or reverse for experts.
- Principles govern how input is presented; they do not replace active or interactive learning activities.
- The number of principles varies by edition (commonly 12 in the 2009 second edition).
