This sourcebook contains nine papers on various aspects of collaborative learning for students with emphasis on college level instruction (though some material relevant to secondary elementary education is also included). Contributors address what collaborative learning is, how is it implemented, how to assess it, and where it is used. Each section of the sourcebook contains an annotated bibliography, as well as a general bibliography containing the references cited in the articles reprinted in that section. Articles and their authors are as follows: "What Is Collaborative Learning?" (Barbara Leigh Smith, Jean T. MacGregor); "Collaborative Learning and the 'Conversation of Mankind'" (Kenneth A. Bruffee); "Collaborative Learning and Positive Change in Higher Education" (Karl A. Smith, David W. Johnson, Roger T. Johnson); "Collaborative Learning: Reframing the Classroom" (Jean T. MacGregor); "Teachers and Learning Groups: Dissolution of the Atlas Complex" (Donald L. Finkel, G. Stephen Monk); "Why Some Groups Fail: A Survey of Students' Experiences with Learning Groups" (Susan Brown Fiechtner, Elaine Actis Davis); "Student Involvement in Learning: Cooperative Learning and College Instruction" (Jim Cooper, Randal Mueck); "Collaborative Learning in the Classroom: A Guide to Evaluation" (Harvey S. Wiener); and "Research on Cooperative Learning: Consensus and Controversy" (Robert E. Slavin). The final section provides: (1) a listing of 50 colleges and universities implementing collaborative learning (with a program description and contact information); and (2) a listing of 5 collaborative learning networks (with descriptions and contact information).
