学生小组合作学习常用“组内异质,组间同质”的分组原则,但组内异质常常造成优等生消极怠工,学困生依赖他人懒于动手,探究效果较差。在探究教学中笔者尝试组成同质学习小组,创新地采取不同性质小组异步探究的合作方式,给予不同能力的学生量身定制分组探究方案,取得较为不错的效果。 The student group cooperates to learn the commonly used “group heterogeneity, group homogeneity” grouping principle, but the intra-group heterogeneity often causes the top students to work absently, and the poor students rely on others to be lazy and the research results are poor. In inquiry teaching, the author tried to form a homogenous learning group, innovatively adopted different types of cooperative methods of asynchronous inquiry, and gave students of different abilities a tailor-made grouping inquiry program and achieved relatively good results.
