二元二次方程组的解法是初中数学教材中的一个难点,在处理该部分教材时,老师费了不少课时,学生练了不少题目,但效果不佳,特别是对于中下学生更感到困难,究其原因,笔者认为,从教者角度讲,从一元一次方程解法开始,到一元二次方程,二元一次方程组解法中都偏重程序解法,强调按步就班,忽视理论的意义和逻辑的根据。从学者角度讲,老师怎么教,学生就模仿怎样做。从思维上讲过分强调了正向思维,使思维凝固。为了从根本上改变这种状态,下面谈几点想法,以便同大家共同 The solution of the binary quadratic equations is a difficult problem in junior middle school mathematics textbooks. When dealing with this part of the textbooks, the teacher spent a lot of time, the students practiced a lot of problems, but the effect is not good, especially for students in the middle and lower school. Difficult to find out, the author believes that from the perspective of the teacher, from the one-ary-one-equation solution method to the one-variable quadratic equation, the binary one-equation equation solution emphasizes the procedural solution, emphasizing step by step, ignoring the significance of the theory. And logical basis. From a scholar’s point of view, how the teacher teaches students to imitate what they do. From the point of view of thinking, over-emphasizing forward thinking makes the thinking solid. In order to fundamentally change this state, let’s talk about a few ideas to share with you
