Giving feedback in instruction may be affected by the constraints of cognitive load as well as presentation of instruction is. We have begun a research project to explore this.

Sloan C 2009 Feedback Ingram Bateman

  1. 1. Feedback, Media, and Cognitive Load<br />Making Feedback Understandable<br />Albert Ingram, PhD<br />Betzi Bateman, MLIS<br />Kent State University<br />
  2. 2. Why is feedback important?<br />What are the functions of feedback?<br />How can we make feedback effective?<br />A Feedback Primer<br />
  3. 3. Small-Scale Feedback<br />Large-Scale Feedback <br />Why is feedback important?<br />
  4. 4. What are the functions of feedback?<br />
  5. 5. How can we make feedback effective?<br />What is effective feedback?<br />Students should learn from it<br />Students should improve products with it<br />
  6. 6. How can we make feedback effective?<br />Variables<br />
  7. 7. Why is Cognitive Load important in instruction?<br />What does the research show?<br />A Cognitive Load Primer<br />
  8. 8. Why is Cognitive Load important in instruction?<br />Working memory capacity is limited<br />Learning occurs when relevant information is connected and operated on in working memory<br />If too much of the processing capacity is taken up with extraneous factors, learning is impaired<br />
  9. 9. What does the research show?<br />Research on integrating visuals and text, visuals and narration<br />Forcing people to divide resources between different sources of information interferes with learning<br />Using methods that work together improves learning<br />
  10. 10. Feedback and Cognitive Load<br />Reducing cognitive load when delivering feedback should increase effectiveness<br />
  11. 11. Hypotheses<br />Research Design<br />Results<br />Current Study<br />
  12. 12. Hypotheses<br />Decreasing the extraneous cognitive load imposed by how feedback is presented will increase learning from the feedback.<br />Delivering feedback (on textual assignments) as audio will reduce cognitive load because there is less need to switch among stimuli<br />Delivering feedback embedded into an assignment will reduce cognitive over delivering it separately<br />
  13. 13. Research Design<br />Use intact classes and existing, real-world assignments that must be handed in as drafts and revised for a grade<br />Repeated measures, within-subjects design in which people receive feedback on multiple assignments in different ways<br />
  14. 14. Results<br />Pilot Study<br />Educational Technology course<br />Series of linked assignments<br />
  15. 15. Plans<br />English Composition Classes<br />Larger N<br />Revised assignments<br />Detailed rubrics<br />Balanced quasi-experimental design<br />
