Because audio can be somewhat more difficult to implement in e-learning projects, it is often overlooked in favor of printed text used to describe on-screen graphics and animations. However, research has shown that, when practical, use of audio narration to explain a visual presentation enhances understanding and related problem-solving.

  • Introduction - Define and describe the Modality Principle as it relates to presenting words as audio narration rather than on-screen text
  • Visual showing on-screen graphics with text-based explanations. The graphic will actually be a very simple depiction of the visual and auditory aspects of sensory memory and how they process information.
  • Psychological reasons why using audio narration is preferable
  • Visual showing same graphics as the first visual, only using audio narration to provide explanations for the graphics
  • Research overview summarizing the results of several studies on this subject
  • Summarize advantages and disadvantages of incorporating this principle in e-learning projects
  • Exceptions to the modality principle
  • How the Modality Principle correlates to the Redundancy Principle (with a link to the article on the Redundancy Principle)
