working memory: considerations

• The limits of working memory is an impediment to learning

• educational content
• navigational structures
• computer environments and interfaces

• Instructional and interface designs, content organization and site architecture should account for these limitations and potentials

focus on attention

• Information processing relative to learning requires a great degree of attention and cognitive resources

• Like working memory, human attention is limited

• Multitasking or splitting attention often causes a drop in performance of all tasks involved

• If the majority of participants’ attention is consumed by the mechanics of your screen environment or wading through poor design and information structures, there will be less cognitive resources for the actual learning objectives.
