Mayer’s 12 Principles of Multimedia Learning
The Temporal Contiguity Principle - Present Information Together
The Temporal Contiguity Principle states that humans learn best when corresponding words and visuals are presented together, instead of in consecutive order.
Similar to the Spatial Contiguity Principal, presenting an animation that is followed by audio narration separates the two in time, resulting in less learning than if the animation and narration were synchronised in time. Related media should be integrated and presented synchronised in time.
How to use the Temporal Contiguity Principle:
If you’re introducing a new process, the animation (or visual) should be occurring at the same time as the voiceover audio. This is preferred to having the voiceover audio play first, and then watching a visual after. You can use this by making sure your voiceover audio is always timed well with your visuals or animations.
