Richard E. MAYER's 12 Principles of Multimedia Learning
Principles for Reducing Extraneous Processing
1- Coherence Principle
Humans learn best when extraneous, distracting material is not included. Use simple text and simple visuals that relate directly to the learner topic.
2- Signaling Principle
Humans learn best when they are shown exactly what to pay attention to on the screen. Hightlight important words and use arrows to point out significant informations.
3- Redundancy Principle
Humans learn best with narration and graphics, as opposed to narration, graphics, and text.
4- Spatial Contiguity Principle
Humans learn best when relevant text and visuals are physically close together. So, make it easy to understand for your learners.
5- Temporal Contiguity Principle
Humans learn best when corresponding words (audio) and visuals are presented together, instead of in consecutive order.
Principles for Managing Essential Processing
6- Segmenting Principle
Humans learn best when information is presented in segments, rather than one long continuous stream. Besides, learners should have control over their learning with customizable settings.
7- Pre-Training Principle
Humans learn more efficiently if they already know some of the basic terms and concepts.
8- Modality Principle
Humans learn best from visuals and spoken words than from visuals and printed words.
Principles for Foster Generative Processing
9- Multimedia Principle
Humans learn best from words and pictures than just words alone.
10- Personalization Principle
Humans learn best from a more informal, conversational voice than an overly formal voice.
11- Voice Principle
Humans learn best from a human voice than a computer voice.
12- Image Principle
Humans learns better with relevant visuals, animations together with voiceovers than talking heads.
