新课程标准的颁布推进素质教育的进程,新课程理念已被广大教师认同,并应用于课堂教学之中。然而,因为对教材编写意图的认识欠缺,流于形式过分追求课堂的活跃,不加考虑运用自主、合作、探究的学习,导致数学课看似热闹,冲淡数学知识的本质内涵。因此,必须关注课堂教学的有效性。 The promulgation of new curriculum standards to promote quality education process, the concept of the new curriculum has been recognized by the majority of teachers, and applied to classroom teaching. However, due to the lack of understanding of the teaching materials, the excessive pursuit of class activity and the unwillingness to use autonomous, cooperative and exploratory learning lead to the seeming excitement of mathematics class and the dilution of the essence of mathematical knowledge. Therefore, we must pay attention to the effectiveness of classroom teaching.
