记得工作之初写教案时常常有这样的感觉,即高中数学的知识虽然具有一定的难度,但备课时感觉最难备的往往却不是知识本身,而是一个知识点向另一个知识点过渡时,不知道怎样实现“平滑过渡”。后来在工作中不断积累经验,发现知识点的过渡还是有一定的章法可循的,其关键之一就是要设计一个能够承上启下的问题。事实上,除了知识的过渡之外,在打开学生的思路、完善知识体系等等方面,问题都发挥着不可替代的作用。拙作尝试谈谈高中数学有效教学背景下的问题设计及相关问题。
I remember the beginning of the work to write lesson plans often have the feeling that high school mathematics, although the knowledge of a certain degree of difficulty, but the preparation of the lesson when the most difficult thing is not knowledge itself, but the transition from one knowledge point to another knowledge point , Do not know how to achieve “smooth transition ”. Later in the work continue to accumulate experience and found that the transition point of knowledge or there is a certain rule to follow, one of the key is to design a problem that can be inherited. In fact, in addition to the transition of knowledge, the problems play an irreplaceable role in opening students’ thinking and perfecting the knowledge system. My Humble Opinion Trying to talk about the problem design and related issues in the context of effective teaching of high school mathematics.
