新课程标准提出:学生要具有终身学习的基础知识、基本技能和方法,倡导全面和谐的教育。改变课程过于注重知识传授的倾向,强调形成积极主动的学习态度,使获得基础知识与基本技能的过程同时成为学生学会学习和形成正确价值观的过程。审题是解题的第一步,细致深入的审题是解题成功的必要前提。著名数学教育家波利亚说:“最糟糕的情况是学生没有弄清问题就进行演算和作图。”事实上,学生常常对此掉以轻心,致使解题失误或陷入繁冗之中。如何全面地、正确地把握问题的已知、所求、领悟问题的条件与结论提供的信息,是解题迅速的必要条件。
The new curriculum standards: students should have the basic knowledge of life-long learning, basic skills and methods, promote a comprehensive and harmonious education. To change the curriculum is too much emphasis on the teaching of knowledge, emphasizing the formation of a pro-active learning attitude, so that the process of acquiring basic knowledge and basic skills at the same time as students learn to learn and form the correct values. Moderation is the first step in solving problems, careful and thorough examination is the necessary prerequisite for solving problems. Polia, a famous math educator, said: “In the worst case, students did not figure out the problem and did the calculation and mapping.” In fact, students often take it lightly, causing mistakes in the problem or into the red tape. How to comprehensively and correctly grasp the information provided by the conditions and conclusions of known, sought, and comprehensible problems is a necessary condition for prompt solution.
