长期以来,一个问题一直困扰着我们教学一线的广大数学教师——如何让数学课堂“活”起来?过去那种“时间加汗水”型的教学方式:教师在课堂上一味地平铺直叙,空洞说教,学生机械式、接受式地学习,教师教得辛苦,学生学得更累,且课堂效益低。久而久之,难免使学生对数学课产生厌学情绪。有一位数学家曾经说过这么一句发人深思的 For a long time, a problem has plagued the vast majority of our teaching mathematics teachers - how to make the math classroom “living” up? The kind of “time plus sweat” type of teaching: the teacher blindly class in the classroom , Empty preaching, students mechanical, accepting to learn, teachers teach hard, students learn more tired, and classroom efficiency is low. Over time, it is inevitable to make students tired of math class mathematics. One mathematician once said that this thought-provoking one
