本刊今年第六期应用题笔谈栏中刊登了余老师写的《怎样帮助学生理解应用题的题意》一文,文中也谈了一些学生理解题意的难点。我们认为学生在理解题意方面,主要有下列几个难点,举例简略分析如下:一、数量的隐蔽性和抽象性应用题中已知条件的数量不是直接给出的,学生就会不明确根据哪两个数组成算式。例如“一个煤矿上半年原计划产煤66万吨,实际每月比原计划多产2.2万吨。照这样计算,完成上半年计划要用几个月?”(五年制小学课本数学第七册第73页例2)
This issue of the sixth issue of this year's application questions column bar column published more than a teacher wrote, “How to help students understand the problem of the application of a title,” the article also talked about some of the difficulties students understand the meaning of questions. We think the students have the following difficulties in understanding the questions, for example, a brief analysis is as follows: First, the number of hidden and abstract The number of known conditions is not directly given, the students will not be clear Which two arrays form the formula? For example, “A coal mine originally planned to produce 660,000 tons of coal in the first half of the year, actually producing 22,000 tons more per month than originally planned. According to this calculation, how many months will it take to complete the first half of the year?” Page 73 Example 2)
