在高中地理教学中,笔者经常发现学生分析问题抓不住重点,看到问题似曾相识却无从下手。究其原因,大多是由于学生对知识的掌握过于片面,缺乏系统性,没能把握好地理知识之间的逻辑关系,没有形成完整的知识链。因此,如何帮助学生对知识进行系统梳理,找出各知识点之间的内在联系,并将这些知识点逐一连接起来,形成完整的知识链,是课堂教学的核心所在。 In high school geography teaching, I often find that students can not grasp the key points of the analysis of the problem, see the problem deja vu but no way to start. The reason is mostly due to students’ mastery of knowledge is too one-sided, lack of systematic, failed to grasp the logical relationship between geographical knowledge, did not form a complete knowledge chain. Therefore, it is the core of classroom teaching that how to help students systematically sort out the knowledge and find out the internal relations among the knowledge points, and connect these knowledge points one by one to form a complete knowledge chain.
