传统小学数学教材中,编排了独立单元的应用题。而现行的课标试验教材不再单独设立应用题单元,而是注重让学生“经历将一些实际问题抽象为数与代数问题的过程,掌握数与代数的基础知识和基本技能,并解决简单的问题”。面对改革,一线教师在观念上已经达成共识,但在具体教学把握中还存在一些偏差。观察当前的计算课,基本形成了教学程序,即问题情境——列式计算(明算理,探算法)——基本计算练习——解决问题,而解决问题成为引出计算
Traditional primary mathematics textbooks, the arrangement of the application of independent units. The current curriculum standard textbook test materials are no longer set up a separate application unit, but rather to allow students to “experience some abstract problems of the number and algebra problems, master the basic knowledge and basic skills of algebra and to solve simple problem”. Faced with the reform, front-line teachers have reached a consensus on the concept, but there are still some deviations in the concrete teaching. Observe the current course of calculation, the basic formation of the teaching process, that is, the problem situation - column calculation (clear counting, probing method) - basic calculation exercises - to solve the problem, and solve the problem as a derivative
