系统性、逻辑性强,是数学学科的显著特点。就是说每一个数学知识点都不是孤立的存在,而是相互依存紧密联系的。因此,掌握各部分知识的整体结构,明确各部分知识的教学要求,是备好课的前提。只有弄清每个知识点在整套、整册教材中的纵向和横向联系,及其具体的教学要求,才能高屋建瓴,有效地避免教学中的盲目性和局限性。
Systematic, logical and strong, is a prominent feature of mathematics. That is to say, every mathematical point of knowledge is not an isolated existence, but interdependent and closely linked. Therefore, mastering the overall structure of each part of knowledge and clarifying the teaching requirements of each part of knowledge are the prerequisites for preparing lessons. Only by understanding each point of knowledge in the whole set, the entire textbook vertical and horizontal links, and its specific teaching requirements, in order to build a house, effectively avoiding the teaching of blindness and limitations.
