Audio in the e learning environment
Audio in the E-Learning Environment

  • Presenting words in audio coupled with graphics, rather than on-screen text, results in significant learning gains

The cognitive theory of learning
The Cognitive Theory of Learning

  • People have separate information processing channels for visual/pictorial processing and auditory/verbal processing

  • Graphics and text process in the same channel and must compete for some limited visual attention

  • Presenting verbal explanations limits the load on the visual channel

Why include audio
Why Include Audio?

  • When presented with text that is explaining attached graphics creates an overload on the visual/pictorial channel

  • The channel has to process both the text and the graphics

  • An overload on the visual channel can be avoided by replacing the text with an audio narration

  • E-Learning courses should avoid overloading when possible

Why continued
Why? Continued…

  • Audio narrations give the learner the opportunity to view the graphic and listen to the explanation simultaneously using two different channels in the brain

  • This prevents an overloading of both channels

  • According to studies taken by Clark & Mayer (2008) when words were spoken explaining graphics rather than printed explanations only, students performed at a much higher rate

The Modality Effect

  • People learn more deeply from multimedia lessons when words explaining concurrent graphics are presented as speech rather than as on-screen text

  • For example this colony development graphic should be presented as speech instead of text only

Audio is most effective when
Audio is Most Effective When…

  • The material being presented is complex and moving at a fast rate

  • Only when using text and graphics together
