Aid selection



Aid selection of key items:
  • Highlight important items
  • Indicate the hierarchy of items
  • Explain key terms up-front
  • Divide presentation into manageable, coherent, sections
  • Learning happens in working memory, which has a very small capacity. Overloading working memory demotivates a learner.
  • Working memory has two channels, one for images, and the other for words (spoken and written). The load experienced in each channel is separate, so e.g. if no images are used, that available space is simply wasted, it can’t be reassigned to cope with an overload in text.
