Multimedia learning

Mayer's research gives you a checklist you can apply in minutes.

• Coherence — cut anything that doesn't teach
• Signalling — cue what matters
• Redundancy — don't narrate on-screen text verbatim
• Contiguity — put related words and images together
• Modality — narrate graphics rather than captioning them
• Personalisation — conversational voice beats formal

Modality guidance never overrides access: always provide captions and transcripts. Design for choice, not for one channel.

Run the checklist over one screen at a time. Most modules improve dramatically from coherence alone.
