《中小学数学(小学版)》2015年第1-2期和2016年第1-2期分别发表了苏莹老师的《解稍复杂方程的疑惑和感悟》(以下简称《苏文》)和李细兴老师的《也谈“稍复杂方程”》(以下简称《李文》)。《苏文》中,苏老师读六年级的儿子问了一道解方程0.95÷4x=0.19的问题。苏老师的解题过程是:0.95÷4x=0.19解:4x=0.95÷0.19,4x=5,x=1.25.这种解法被儿子否定之后,苏老师并没有止步,又查阅了有关材料,仍然未能如愿,进而想通过对师生检测的方法找到正确答案:在对学生的检测中,把缸看作一个整体的占76.19%(被检测学生总数224
“Primary and Secondary Mathematics (Primary)” 2015 1-2 and 2016 1-2 respectively published Su Ying’s “doubts and perceptions of slightly complex equations” (hereinafter referred to as “Su Wen”) and LiXiaoXing teacher’s “talk about” a little complex equation “” (hereinafter referred to as “Li Wen”). In “Su Wen”, son Su who is in sixth grade asks for a solution of the equation 0.95 ÷ 4x = 0.19. Sol teacher problem solving process is: 0.95 ÷ 4x = 0.19 solution: 4x = 0.95 ÷ 0.19, 4x = 5, x = 1.25. This solution was denied by his son, Su did not stop, but also access to the relevant materials, still Failure to do so, and then want to detect teachers and students through the method to find the correct answer: In the test of students, the cylinder as a whole accounted for 76.19% (the total number of students to be detected 224
