“周长和面积”对于三年级学生来说是两个重要概念,然而当周长和面积两个概念在一起时,学生经常出现混淆、单位错乱、错误较多等情况,这些不知困扰了多少教师。近期,笔者和团队教师在交流分析和实践总结中,发现了一些收获。笔者设计了这样一堂“思维式”复习课“周长和面积”。教学环节包括:第一环节,创设复习载体;第二环节,交流思维过程和梳理提升思维。在复习活动中,不仅注重引导学生复习和巩固知识,梳理和沟通知识点,更关键的是立足复习载体,发展学生思维。前者,老师们做得较好,而后者往往被老师所忽视,从而使得复习课变成练习课,失去复习课所应具备的生命力。

Teaching links include: the first part, the creation of a review carrier; the second part, to exchange thinking process and sort out to enhance thinking. In the review activities, not only focus on guiding students to review and consolidate knowledge, sort out and communicate knowledge points, the more critical is based on the review carrier, the development of student thinking. The former, teachers are doing better, while the latter is often neglected by teachers, making the review class into practice class, lost the vitality of the class should have.
