“动手实践、自主探索、合作交流”是《数学课程标准》倡导的三大学习方式.新一轮课程改革以来,合作学习已成为中小学课堂的一大“亮点”.越来越多的教师在教学中设计并运用这一教学策略.合作学习过程中的师生交流、生生互动为课堂注入了新的活力,它把教学建立在了更加广阔的交流背景之上.合作学习不仅能提高学生学习的参与度,而且能增进教学效果,培养学生的合作意识,真正让每个学生在数学上 “Hands-on practice, independent exploration, and cooperation and exchange” are the three major learning methods advocated by the “Mathematics Curriculum Standards.” Since the new round of curriculum reform, cooperative learning has become a major “bright spot” in primary and secondary classrooms. More teachers are designing and applying this teaching strategy in teaching. Teacher-student interaction and student-to-student interaction in the cooperative learning process has injected new vitality into the classroom. It has established teaching in a broader context of communication. Cooperative learning It can not only improve student’s participation in learning, but also improve teaching effect, cultivate students’ sense of cooperation, and truly make every student in mathematics.
