复习课担负着“知识结构的组织”和“数学知识应用,数学思想方法提炼”的双重任务,前者是为了建构知识之间的关系,后者为了巩固知识,培养应用知识和解决问题的能力,发展数学思维。复习课区别于新授课之处在于学生对学习内容的“已知”发生了巨大的变化,因此,复习课的逻辑起点应该是洞悉学生的元认知水平,即要对学情(知识技能的掌握、活动经验、复习心理及状态)进行深入的剖析,知已知彼,方 The review class is responsible for the dual tasks of “the organization of knowledge structure” and “the application of mathematical knowledge and the refinement of mathematical ideas and methods”. The former aims at building the relationship between knowledge and the latter in order to consolidate and cultivate applied knowledge and solve problems Problem-solving ability to develop mathematical thinking. The difference between the new curriculum and the new curriculum is that the students ’great changes have taken place in the “known” content of the learning content. Therefore, the logical starting point of the review curriculum should be to understand the students’ metacognition level, that is, Skills mastery, activity experience, review psychology and status) to conduct an in-depth analysis, knowing that they, parties
