为进行一项课题研究,就苏科版《义务教育教科书·数学》八年级下册第十章“解分式方程”这一内容,我们备课组在两个同类班级A班和B班(班级平均分、优分率、及格率基本一致)进行了同课异构的交流活动,由两位教师分别执教。两位教师在本节课的核心知识点即如何解分式方程的教学环节上基本一致,而在检验环节的教学上,有明显的差异,现展示如下。1教学对比以解有增根的分式方程(5x-4)/(x-2)=(4x+10)/(3x-6)-1教学为例(此题为例2,是课本上的探索题)。(例1是课
To carry out a research project, Su Ke version of “compulsory education textbook mathematics” eighth grade eighth chapter “solution equation” this content, we prepare class in two similar classes A and B classes (Class average score, excellent score rate, the passing rate is basically the same) for the same class heterogeneous exchange activities, the two teachers were coached. The two teachers in the core knowledge of this lesson that is how to solve the partial differential equations of teaching are basically the same, but in the teaching aspects of the test, there are obvious differences are shown below. 1 teaching comparison to solve the root problem of fractional equation (5x-4) / (x-2) = (4x + 10) / (3x-6) -1 teaching as an example (the title of Example 2 is the textbook Exploration questions). (Example 1 is a lesson
