期中考试前,我上了一节复习课,这节课主要针对学生解决问题中出现的问题,选择一些题目,以此来提高学生的思维能力.在我选的题目中有这样一题:小红有15个矿泉水瓶,商家为了促销,规定每4个空瓶换一瓶水,问:小红最多能喝到多少瓶水?我自以为对我班现在的学生而言,是有一定难度的,这道题目中涉及了一个喝完后可以再换的问题,但是这种反复的次数只有一次,我想学生应该能够理解.于是我把这题放在了课堂教学的中间,像以前一样我从零星举手的学生中先找一个女生回答,这名女生很快就把自己的方法与答案告诉了大家.
Before the midterm exam, I went to a review class, this class mainly for students to solve problems that arise in the problem, select a number of topics, in order to improve the thinking ability of students in the title of the election I have such a question: small Red has 15 bottles of mineral water, merchants in order to promote the provisions of every 4 empty bottles for a bottle of water, Q: How many bottles of red water can drink? I think my class for students now, there is a certain degree of difficulty , This topic involves a can be replaced after drinking problem, but this repeated only once, I think students should be able to understand. So I put this question in the middle of classroom teaching, as before I asked a girl from a sporadic hand to find a girl to answer, the girl quickly put their own methods and answers to tell you.
