曲线的交点问题是解析几何中的重要问题之一,但是教材(必修)P_(57)2.4曲线的交点一节内容设计十分简炼,笔者在听课中发现,有的青年教师由于缺乏对教材的深入研究,照本宣科,读读开头话,讲讲两例题.远远不能达到应有的教学目的.笔者认为,只有做到:立足教材、深化知识,既提炼思想方法,又培养思维能力,才是教学的关键所在.本文根据自己的教学实践,谈几点肤浅的做法与体会.
The intersection point of the curve is one of the important problems in analytical geometry, but the content of the section of the intersection point of textbook (required) P_ (57) 2.4 curve is very concise. The author found in the lecture that some young teachers were lacking in teaching materials. In-depth study, according to the script, read the opening words, talk about two examples. Far from achieving the purpose of teaching should be. The author believes that only by: based on teaching materials, deepen the knowledge, both to refine ideas and methods, but also to cultivate thinking ability, is The key to teaching. This article talks about superficial practices and experiences based on one’s own teaching practice.
