著名数学教育家G·波利亚曾说:“一个专心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个方面,使得通过这道题,就好像一道门,把学生引入一个完整的理论领域.”一句话道出了老师精选题目,对教学是多么的重要.而一道立意高远、内涵丰富的高考试题,蕴含着丰富的思想方法,具有较好的研究性、探索性和延展性.其解法是多样的,研究它的目的不仅仅是为了掌握解题的操作,多找几种解法,还要在多角度的思考过程中,理解
G. Polia, a well-known mathematical educator, once said: “A teacher who concentrates on lesson preparation can come up with a meaningful but not too complicated topic to help students explore all aspects of the problem so that it is as if A door, the students into a complete theoretical field. ”" A word out of the teacher’s selection of topics, how important teaching, and a deliberately lofty, rich connotation of the college entrance examination, contains a wealth of ideas and methods, with Better research, exploration and scalability.His solution is diverse, the purpose of its research is not only to master the operation of the problem-solving, find a few solutions, but also in the multi-angle thinking process, to understand
