一、问题的提出中学生在解一元一次方程多数都是采取程序的方法即去分母、去括号、移项法来解一元一次方程,然而不少学生在去分母时容易产生漏乘某项的错误,这种错误现象实质上表明学生并不完全理解方程的概念与方程潜在下的等价结构,因此笔者想从另一种方法平衡模型法来分析学生遇到的错误。 First, the problem raised Middle school students solve a dollar equation is the majority of the way to the denominator, go to the parentheses, move the law to solve the equation of a dollar, but many students prone to miss the miss when denominated an error This error phenomenon essentially indicates that students do not fully understand the potential equivalence of equations and equations. Therefore, I would like to analyze the errors encountered by students by balancing the model method with another method.
