Nine Ways to Reduce Cognitive Load in Multimedia Learning http://www.uky.edu/~gmswan3/544/9_ways_to_reduce_CL.pdf

Present information in learner-controlled segments rather than as a continuous presentation.

In segmenting, the presentation is broken into bite-size segments.

Examples of Cognitive Load Reduction

Provide cues to the learner about how to select and organize the material.

Add signals on how to process the material to reduceprocessing of extraneous material.

Add numbers to represent steps.

Material is too long and complex

Sometimes, instructors produce notes or guidelines that can be overwhelming for students.A potential problem is that the processing demands evoked by the learning task may exceed the processing capacity of the cognitive system - a situation we call cognitive overload. (Mayer and Moreno, 2003)

Problem Solution

""UUnniitt 11,, PPaarrtt 11..""

Highlight or announce titles and subtitles, using font, size and color, or voice tone.

Allow some time between segments of the presentation.

Use visual representation:arrows,tables,charts, and graphics

Split text and/or audio into smaller chunks.Number sections if there is a sequential order.Use bulleted lists otherwise.
