Cognitive Load Theory (CLT)
Mismanagement of multimedia elements can overwhelm and impair the learner’s capacity to process info by introducing distraction, redundancy, and other principles outlined by CLT theorists.
Ways to reduce cognitive load in eLearning
When it is not feasible to remove all the embellishments in a multimedia lesson, cognitive load can be reduced by providing cues to the learner about how to select and organize the material:
Mayer, R. E., & Moreno, R. (2003). Nine Ways to Reduce Cognitive Load in Multimedia Learning. Educational Psychologist, 38(1), 43-52.
ACT-R (Adaptive Character of Thought) theory: Declarative and Procedural Knowledge
Declarative Knowledge = facts, terms and other specific “chunks” of info. They precede many of the screencasts in tutorials as “pre-training” sections: introducing terms, helping understand larger objectives. “Chunks” introduced early in a tutorial help students be less distracted by unfamiliar facts when more complex procedures, concepts etc. are introduced – one of the ways to reduce/eliminate cognitive overload.
Recommendation based on this theory
