Document Summary
Ltm - building blocks: concepts - meaningful categories based on defining attributes, productions, schemas. Organised structure that capture knowledge and expectations of some aspect of the world . Characteristics of schemas: ltm is actively constructed using schemas, activated schemas determine what incoming information is relevant, schemas are continually reconstructed. Schema automation: achieved by practicing skills until they do not require consciously controlled and effortful processing, when basic mental operations occur automatically, resources are available for more sophisticated cognitive operations. Summary: schemas affect not only what we memorize, but how we think, reason, and solve problems. Intelligence - in number and complexity of acquired schemas: nature of expertise. Educational implications - long term memory and schemas. Instructional implications: what students already know influences what and how they learn; help them activate relevant prior knowledge to link with new information, help students organise related information into meaningful groups/chunks.
