著名数学家G·波利亚说:“一个专心的认真备课的老师能够拿出一个有意义但又不太复杂的题目,去帮助学生发掘问题的各方面,使得通过这道题,就好象通过一道门户,把学生引入一个完整的理论领域.”高中数学教材中的例、习题凝聚了许多专家、学者的心血和经验,教材上的例、习题是教师开展教学的依据,也是学生学习探究的范本.在数学教学中,我们不能就题论题,而应重视对例、习题的教育潜能作进一步的探究,以充分挖掘其深层功能,从而给学 The famous mathematician G. Pollaia said: “A dedicated lesson preparation teacher can come up with a meaningful but not too complicated topic, to help students explore all aspects of the problem, so that through this question, just fine Like through a portal, the students into a complete field of theory. ”" High school mathematics textbooks, examples of exercises, many experts and scholars unite the hard work and experience of teaching materials, exercises on the basis of teachers teaching, but also students In the teaching of mathematics, we can not discuss the topic, but should pay more attention to the potential of the education of examples and exercises for further exploration to fully tap its deep functions, so as to learn
