抓好简单应用题向两步计算应用题过渡,既是应用题教学的重点,又是难点。解决这个难点的关键是找出学生在过渡中所遇到的主要障碍及其原因,并采取针对性措施,从而使问题得到解决。学生学习两步计算应用题主要存在三方面的问题:一、不易摆脱解答简单应用题中形成的思维定势,对两步应用题的学习产生负迁移。 Grasp the simple application of the problem Two-step calculation of the application of the transition, is not only the focus of the application of teaching, but also difficult. The key to solving this difficult problem is to find out the major obstacles encountered by the students during the transition and their causes, and take targeted measures so that the problems can be solved. There are three main problems in student learning two-step computing application questions: One is not easy to get rid of the thinking tendency formed in the solution to the simple application question, and the negative transfer to the two-step application question learning.
