Mayer, R. E., & Moreno, R. (2003). Nine Ways to Reduce Cognitive Load in Multimedia Learning. Educational Psychologist, 38(1), 43-52


The three Assumptions about how the mind works in Multimedia Learning are Dual Channelled (visuals and verbals), Limited Capacity (linked to Cognitive Load Theory - working memory has a limited capacity) and Active Processing (there is active cognitive processing in the two channels).


Designers of Multimedia Learning Materials need to consider the possibility of "overloading" the cognition of the user.  The Load reducing methods employed in this research include off-loading, segmenting, pre-training, weeding, signalling, aligning, eliminating redundancy, synchronising and individualising.
