学习数学知识,要懂得利用数学知识解决数学问题。对于较简单的数学问题,学生会做,而对于一些较难的题目,许多学生往往无从下手,或者走弯路,找不到解题途径。解决问题的关键是要找到解题的切入点,也就是明确解题应往哪个方向,结合哪个知识去思考,因此,学生在解答较难的题目时,在分析题目的已知和所求的基础上,需要选择一个解题的切入点。那么,如何寻找解题的切入点?就本人在应用题教学中是如何教会学生找准问题的切入点谈一谈个人的做法。
To learn math knowledge, we must know how to use math knowledge to solve math problems. For simpler math problems, students do, and for some difficult topics, many students often have no way of getting started or detours and can not find a solution. The key to solve the problem is to find a solution to the starting point, that is, a clear solution to which direction should be combined with what knowledge to think, therefore, students in the difficult questions to answer, in the analysis of the known and asked questions Based on the need to choose a solution to the entry point. So, how to find a solution to the problem? On how to teach students how to identify problems in the application of the teaching of personal point of talk about personal practices.
