学生学习两步计算应用题是从简单应用题向解三、四步应用题过渡的中间环节,其学生情况直接影响以后的学习,因此,加强两步应用题的者学十分重要。如何激活学生思维,提高学生解答应用题的能力。在两步应用题教学中,我认为多给学生“变式”训练。能激活学生思维,分析数量关系,找到解题思路,提高解题能力。所谓“变式”题,就是指通过改变应用式的叙述方法重点词语、条件或问题等,使应用题的结构内容、数量关系等发生变化,从而使分析解答问题的思路,方法等的变化。
Student learning two-step calculation of application questions is from the simple application problem solving three, four-step application of the transition intermediate links, the students directly affect the future learning, therefore, to strengthen the two-step application of the scholarship is very important. How to Activate Students ’Thinking and Improve Students’ Ability to Solve Applied Problems. In the two-step teaching of application problems, I think giving students more “variant” training. Can activate student thinking, analyze the relationship between quantity, find solutions to problems and improve the ability to solve problems. The so-called “variant ” title, that is, by changing the application of the narrative method of key words, conditions or problems, the structure of the application questions content, the relationship between the number of changes, so that analysis of the problem-solving ideas, methods Variety.
