许多教师往往会产生这样的困惑:题目讲得很多,但是学生总是停留在模仿解题的水平上,只要条件稍稍一变则束手无策。学生一直不能形成较强的解决问题的能力,更谈不上创新能力的形成。究其原因中很重要的原因之一就在于教师在教学中仅仅是就提讲题,不会在数学基础知识背后挖掘出尤为重要的数学思想方法。要知道:授之以“鱼”不如授之以“渔”。问题是数学的心脏,方法是数学的行为,思想是数学的灵魂。不管是数学概念的建立,数学规律的发现,还是数学问题的解 Many teachers often have such confusion: the subject is much talked about, but students are always stuck at the level of problem-solving and helpless as conditions change slightly. Students have not been able to form a strong ability to solve problems, let alone the formation of innovative ability. One of the reasons why this is so important is that teachers are merely talking about teaching in teaching and will not dig out the most important mathematical thinking behind the basics of mathematics. To know: granted to “fish ” is better to grant “fishing ”. The problem is the heart of mathematics, the method is mathematical behavior, the idea is the soul of mathematics. Whether it is the establishment of mathematical concepts, the discovery of mathematical laws, or the solution to mathematical problems
