1. What is the Self Explanation Principle?

  An effective, deep learning strategy that engages students in actively constructing and   
  monitoring their knowledge to help them understand complex phenomena better by providing 
  explanations during learning.

2. Key Cognitive Mechanisms of Self Explaining

  Generating inferences to fill in missing information
  Integrating information within the study materials
  Integrating new information with prior knowledge
  Monitoring and repairing faulty knowledge

3. Studies show that self-explaining…

  Is trainable
  Can be beneficial even when explicitly elicited/prompted
  Can vary greatly among people in terms of quality & quantity 
  Can require scaffolding that goes beyond prompting or training
  Takes place more frequently with students having greater prior knowledge 
  Is more necessary for effectively learning in multimedia than single media context  

4. Medium Matters for Self-Explanation

  Frequency – lowest in text-only situations, more frequent in multimedia situations and most      
  frequent is diagram-only situations (36%, 68% & 92% respectively)
  
  Learning Gains – Roughly equal for text-only and multimedia learning context.  Substantially  
  higher in a diagrams-only context  (22%, 20% & 43% respectively)

5. Instructional Design Implications

  AVOID...
  Placing undue cognitive load on the learner by presenting related text and diagrams closely 
  The use of unrelated information
  The duplication of messages across 2 different modalities that use the same information    
  processing channel (such as text and narration)
  ENCOURAGE...
  An environment that assists learners to think inwardly and reflectively 
  Students to monitor and test their evolving understanding
  The generation of new inferences in which the learner relates information within and between   
  media and relates this to prior knowledge 
  Verbal self explanations versus written/typed explanations
  Students to generate as well as explain their own diagramsE...
