在学生学过整数、分数及小数的加、减、乘、除之后,最感困难的,同时也是教师最难给学生讲解的,便是遇到一个应用问题时,如何找出四则算式来。过去我们讲解这些问题,虽然也运用了直观、分析、比较等几种方法,但还是注入式的教学多,对培养学生独立解题能力不够,因此,学生对应用问题往往缺乏分析能力,很难找到解题方向,这学期经过我们检查分析,认为教师要讲四则应用问题,不仅要深入钻研教材,研究每一种应用问题的讲解方法,更主要的是怎样引导学生积极思维,提高学生分析能力,找出解题的关鍵,现在我们初步得出几种方法介绍于下:请同志们指正。 After the students have studied the addition, subtraction, multiplication, and division of integers, fractions, and decimals, the most difficult ones and the most difficult for the teacher to explain to the students are how to find out four formulas when they encounter an application problem. In the past, we explained these problems. Although we also used intuitive methods, analysis, and comparison methods, we still have a lot of injection-type teaching methods. We don’t have enough ability to train students to solve problems independently. Therefore, students often lack the analytical skills for application problems. After finding out the direction of the problem, this semester has passed our examination and analysis. We believe that teachers should discuss four application problems. They should not only study the teaching materials in depth, study the explanation methods for each application problem, but also guide students’ positive thinking and improve their analytical skills. To find out the key to problem solving, now we have tentatively come up with several ways to introduce it: Ask the comrades to correct me.
