Small-group cooperative learning provides an alternative to both traditional whole-class expository instruction and individual instruction systems. The procedures described in this volume are realistic, practical strategies for using small groups in mathematics teaching and learning with methods applicable to all age levels, curriculum levels, and mathematical topic areas. Included are: (1) an introduction and overview to orient the reader; (2) problem solving and exploration with manipulative materials in groups of four; (3) a bilingual integrated mathematics/science program addressing classroom status; (4) team learning approaches based upon individual accountability and team recognition; (5) a general conceptual model of cooperative learning with a detailed discussion of its basic components; (6) three computer-based cooperative learning strategies for classroom use; (7) various learning activities for the initiation of a cooperative classroom setting; (8) procedures for group problem solving and inquiry in algebra, gemoetry, and trigonometry; (9) a narrative on cooperation in heterogeneous group mathematics in the Netherlands; (10) group interactions in algebra and calculus using computers for problem solving; (11) free exploration and guided discovery in cooperative groups using concrete models; (12) procedures for guided discovery in cooperative groups with examples from calculus; (13) issues affecting the use of cooperative learning in mathematics with emphasis on teachers' decision making and factors affecting implementation; and (14) appendices that include information about the sponsoring organizations, annotated survey responses from classroom teachers, and an annotated listing of 38 resource materials with contact persons.
