All rights reserved The Cognitive Information- Processing Approach Children manipulate information, monitor it, and strategize about it. Characteristics of this approach include: –Thinking –Change mechanisms Encoding Automaticity Strategy construction Transfer Metacognition –Self-modification

All rights reserved The Good Information-Processing Model Competent cognition results from interacting factors: Strategies, content knowledge, motivation and metacognition 3 factors that lead to cognitive success: 1.Children are taught to use a particular strategy, and learn about its advantages  specific knowledge 2.Teachers demonstrate shared features of strategies  relational knowledge 3.Students recognize the benefits of sing strategies  general strategy knowledge; and attribute successful learning outcomes to efforts in evaluating, selecting and monitoring strategy use  metacognitive knowledge and activity

State why a strategy is useful. State when and where a strategy can be used. Model the strategy. Provide students with guided strategy instruction. Encourage students to use strategy across related learning tasks. Convince students that strategy really works.
