多年前听到一位数学教育名家的一句话:“衡量课堂教学效率高低的唯一标准,是学生的参与程度。”对此深有同感。我们不想对是否“唯一”展开争论,但学生的“参与”肯定是使知识内化的必要条件,用学生的参与程度来衡量课堂教学效率高低与教师在课堂 Years ago, I heard a famous mathematics education expert: “The only criterion for measuring the efficiency of classroom teaching is the degree of student participation.” We don’t want to debate whether we are “unique,” ​​but the student’s “participation” is definitely a necessary condition for internalizing knowledge. We use the degree of student participation to measure the level of classroom teaching efficiency and teachers in the classroom.
