This text provides practical ideas for educators who struggle with meeting the diverse needs of children in today's classrooms. Educators often struggle to design groups that work with members who cooperate, work productively, and make academic progress. This text provides answers to teachers' questions using a research-based Knowledge, Power, and Affection conceptual model represented by a graphic organizer. Readers will use this cognitive framework to understand the key factors that affect group success for both small groups and the class as a whole. This useful book links theory to practice through clear, readable language and a rich collection of examples, vignettes, and activities.Nagel, Greta K. is the author of 'Effective Grouping for Literacy Instruction', published 2000 under ISBN 9780205309207 and ISBN 0205309208.
