Chapter Eight Information Processing How well do we remember what we learn in school? Copyright © Houghton Mifflin Company. All rights reserved. 5-2 Overview • The information processing view of learning • A model of information processing • Metacognition • Helping students become strategic learners Copyright © Houghton Mifflin Company. All rights reserved. 5-3 Information processing view of learning: Assumptions • Information focuses on the mind of the student – Information is processed in steps or stages – There are limits on how much information can be processed at each stage – The human information processing system is interactive Copyright © Houghton Mifflin Company.

All rights reserved. 5-6 The sensory register • Capacity – Very large • Duration – 1 to 3 seconds • Contents – Information perceived by the sensory receptors (encoded as perceived) Copyright © Houghton Mifflin Company. All rights reserved. 5-7 The sensory register and its control processes • Recognition – Noting key features of a stimulus and relating them to already stored information • Attention – Selective focusing on a portion of the information currently stored in the sensory register Copyright © Houghton Mifflin Company. All rights reserved. 5-8 Short-term memory (working memory) • Capacity – 7 +/- 2 chunks of information • Duration – 20 to 30 seconds • Contents – What you are currently thinking about (information from the sensory register and information from long term memory) Copyright © Houghton Mifflin Company. All rights reserved. 5-9 Short-term memory and its control processes • Rehearsal – Maintenance rehearsal —repeating information over and over again; no effect on long-term memory storage – Elaborative rehearsal —relating new information to knowledge already stored in long-term memory Copyright © Houghton Mifflin Company. All rights reserved. 5-10 Short-term memory and its control processes • Elaborative Rehearsal – Organization • Organizing information into chunks (related items) so that more information can be stored and thus remembered – Meaningfulness • Organizing material and relating it to ideas and experiences already known Copyright © Houghton Mifflin Company. All rights reserved. 5-11 Short-term memory and its control processes • Elaborative Rehearsal Cont’d – Visual imagery encoding (Paivio - dual coding) • Generating mental images of objects, ideas, and actions to aid in the storage of memories Copyright © Houghton Mifflin Company. All rights reserved. 5-12 Long-term memory • Capacity – Unlimited • Duration – Permanent, long-term • Contents – Schemata – an abstract structure of information Copyright © Houghton Mifflin Company. All rights reserved. 5-13 What is metacognition? Metacognition is… our knowledge about attention, recognition, encoding, storage, and retrieval and how those operations might best be used to achieve a learning goal.
