《全日制义务教育数学课程标准》(2011年修订版)给了方程一个明确的概念界定,即方程是指含有未知数的等式,并将方程这个知识版块放在了五年级来教学,不仅突出了学生学习方程的重要性,而且还考虑到学生的年龄特征以及心理发展水平等因素来安排方程的教学。其实,方程作为一种重要的数学思想和方法,对于每一个个体通过假设和验证的方法来认知世界、适应社会等,都具有极其深远的意义和作用,尤其是在帮助学生解答实际问题和排解实际障碍上,更是一种必不可少的数学思维和素养。然而,在实际的方程教学中,由于教法的局限性,学生并不能完全体
The Full-Time Compulsory Education Mathematics Curriculum Standard (Revised 2011) gives a clear conceptual definition of equations where equations refer to equations that contain unknowns and put the knowledge of the equation in the fifth grade to teach, not only to highlight Students learn the importance of equations, but also taking into account the age characteristics of students and psychological development and other factors to arrange the teaching of equations. In fact, as an important mathematical thought and method, equation has extremely profound meaning and function for each individual to recognize the world and adapt to society through assumptions and verification methods, especially in helping students to answer practical problems and Solve the actual obstacles, but also an essential mathematical thinking and accomplishment. However, in the actual teaching of the equation, due to the limitations of the teaching method, students can not completely
