一、问题的提出很多初中数学教师常抱怨:学生们遇到应用题时就喜欢用算术方法钻牛角尖,而不懂得灵活运用方程方法去解决.与此同时,小学数学教师也反映,在平时教学列方程解应用题时,学生大多能按照要求列方程解决,但单元教学完后,再遇到类似问题时,80%的学生还是会选择用算术方法解题.中小学教师都感到疑惑:学生们为什么不喜欢用方程去解决应用题?我们又应该怎样引导学生习惯用方程去解决应用题呢?
First, the problem raised Many junior high school math teachers often complain: students encounter problems when using the arithmetic like drilling the tip, but do not know how to use the equation method to solve flexible .At the same time, primary school mathematics teachers also reflected in the usual teaching Most of the students can solve the problem according to the column of equations, but after the unit is finished teaching, 80% of the students still choose to use arithmetic to solve the problem. The primary and middle school teachers all wonder: the students Why do not you like to use the equation to solve the problem? How should we guide students to use equations to solve the problem?
