【Abstract】Problem-solving has always been one of the key points of mathematics teaching. In order to realize the effective development of subject teaching and achieve the effective development of students' abilities, teachers must be able to conduct in-depth research and carry out problem-solving teaching in accordance with the actual situation in the teaching process. The equation is an important model learned by students in the upper grades of primary school. It plays an important role in promoting the problem-solving of students in the subsequent learning process. Therefore, the cultivation of the ability to solve equations has become one of the important directions for mathematics teachers to conduct mathematics teaching research.

方程作為一种将多种实际问题“数学化”的数学模型,是实现实际问题有效解决的重要途径之一,解方程相较于直接计算而言,其实现了未知量在等式中的直接展现,学生在其中可以通过对题目中已知数、未知数和表示全部含义相等关系的展现,在通过字母对未知数的展现,建立方程等式,进而通过解方程获得未知数的值,求得所求数据内容。而在一般的算数计算中,是由已知入手,通过步步推究得出未知的数据,在这样的解题规律中,未知数是不参与计算的,一切计算行为都为了实现未知数的求出。相应的,解方程与一般的算术解法相比,其更加简便且容易操作。但在当前的教学实际中,笔者研究发现学生的解方程能力发展普遍存在较大的问题,为了实现学生解方程的有效进行,教师在实际的教学中就要能将学生方程解题能力的培养重视起来,采用有效的教学策略开展教学。……
