  1. Learning, Memory & Design By Vridhi Tuli, Educ 391X Stanford University, 2007

  2. Models of Memory

  3. Modal Model of Memory(Atkinson & Shiffrin 1968) • WM (or STM) & LTM are distinct modalities that interact with each other • Model too simplistic

  4. Baddeley’s Model of Working Memory http://books.google.com/books?id=fMgm-2NXAXYC&pg=PP5&vq=modal&dq=baddeley%27s+model+a-baddeley&sig=SRwbyQil4vlkI7cl84vJ9G3SnPA • WM is not unified as the modal model assumes • Audio, Visual Systems (Storage) & Central Executive (Processing)

  5. Experimental Design

  6. Experimental Design Considerations • Design: Are you using an experimental design approach with an IV, DV, control and test group? • Reliability: Can your results be replicated? • Construct Validity: Do your variables measure what they intend to measure? • External Validity: Can your results to be generalized to real-world settings? • Significance: Are your results statistically (p>=.05) and practically significant?

  7. Practical Significance: Effect Size “The effect size helps us to know whether the difference observed is a difference that matters” Example Mean age of girls in Educ391= 24, SD=2 Mean age of guys in Educ391= 30, SD= 5 Effect Size = 1.57! Practically Significant

  8. Learning Activity

  9. Once upon a time, there was a snowman living in a cold island. He was made of snow, carrots and wood and wore a striped blue scarf around his neck. The snowman was ill and his nose was dripping because of the cold he caught. The doctor came to see him. He brought a book and some bandages with him. He did a checkup on snowman and gave him some medicines consoling him that he will get well soon. But the snowman was still sad and was ready to cry.

  10. Group 1 will remember more! Effects of Prior Knowledge
