课堂生成资源是在教学过程中动态生成的,增根与无解是分式方程中学生容易混淆的两个概念,而因此而引发的学习冲突,正是有效的课堂生成资源,及时捕捉并正确地利用这种生成资源有利于教学目标的实现。
The resources generated in the classroom are dynamically generated during the teaching process. The increasing roots and the non-solutions are two concepts confusing to students in fractional equations. Therefore, the learning conflict triggered by the classroom is an effective resource for classroom generation, which can be captured in time and correctly The use of such resources is conducive to the realization of teaching objectives.
