课程改革实施以来,教师们更加注重教学情境如何创设、学习方式如何选择、活动形式如何多样……这本无可厚非,但一些教师由于对教材的理解、使用有失偏颇,导致课堂教学只注重形式而忽略实质,学生对知识的理解仅停留在表层,数学思维得不到发展,使课堂教学显得低效甚至无效。教学的有效性始终是课堂教学的生命线。因此,教师应如何合理地运用教材,以提高课堂教学的有效性是我们必须思考的现实问题。

The effectiveness of teaching is always the lifeline of classroom teaching. Therefore, how teachers should use teaching materials reasonably to improve the effectiveness of classroom teaching is a realistic problem that we must think.
