数学课少不了要讲解例题。选择好恰当的题目,将给学生以多方面的启示:概念如何运用?思路如何开拓?知识怎样串通?解法孰优孰劣?虽然只讲个别题,却能使学生触类旁通。收举一反三之效。在《参数方程、极坐标》这章教学之后,我从课本上道题“化x~2=2p(y+p/2)为极坐标方程”出发,紧扣“解几”教材,逐步改换结论,帮助学生归纳总结了许多常用解题方法,从而扩大了知识而,培养了学生灵活运用知识的能力。
In mathematics, it is necessary to explain examples. Choosing the right topic will give students a variety of inspirations: how to use the concept, how to develop ideas, how to collude knowledge, and how to solve the problems. Although only a few questions are spoken, students can be comprehended by analogy. Receiving results from the other three. After the teaching of Parametric Equations and Polar Coordinates, I set out from the textbook “Turn x~2=2p(y+p/2) to polar equations” and closely follow the “solutions” textbook to gradually change the textbooks. In conclusion, it helps the students to summarize and summarize many commonly used problem-solving methods, thus expanding knowledge and cultivating the students’ ability to use knowledge flexibly.
