小组合作学习是新课程所倡导的学生学习的重要方式之一,越来越多的老师在课堂教学过程中采用这一方法。合作学习小组是一种新型的“结构—功能”联合体,通常由4~6名在性别、学业成绩、个性特点等方面具有异质性的学生组成,尽可能地使小组的组成体现一个班级的缩影。组内异质可保证组内各个成员之间在各方面的差异互补;组间同质又为全班各个学习小组之间在同一起点和同一水平上公平、合理的竞争创造了条件。遵循“组内异质,组间同质”的原则, Group cooperative learning is one of the most important ways to promote students’ learning in the new curriculum. More and more teachers use this method in classroom teaching. The cooperative learning group is a new type of “structure-function” consortium, usually composed of 4-6 students who have heterogeneity in terms of gender, academic achievement, personality characteristics and so on, and make the composition of the group reflect as much as possible A microcosm of a class. Heterogeneity within a group ensures complementarity among the various members of a group in all respects; homogeneity among groups creates conditions for fair and reasonable competition among the entire study group at the same point and level. Follow the principle of “heterogeneity within groups, homogeneous between groups”
