近年来,小学数学领域关于课堂教学的新提法越来越多,如:“简约课堂”、“灵动课堂”、“有效课堂”、“高效课堂”、“幸福课堂”……这些提法就是要求我们教师要优化教学过程,提高教学效率。为了体现新课改的理念,相当一部分数学老师费尽心机,刻意追求改变教学方式,通过组织学生自主探究、实践操作、小组讨论、合作交流等活动,实现课堂教学目标。虽然学生课堂参与热情异常饱满,但是形式的背后透露出浮华,折射 In recent years, there have been more and more new references about classroom teaching in the field of elementary mathematics, such as: “Simple Classroom”, “Smart Classroom”, “Effective Classroom”, “Efficient Classroom”, “ Happy classroom ”... ... These references require that we teachers to optimize the teaching process and improve teaching efficiency. In order to embody the concept of the new curriculum reform, a considerable part of the maths teachers try their best to change the teaching methods and organize the students’ self-exploration, practical operation, group discussions, cooperation and exchange activities to achieve the goal of classroom teaching. Although the students’ enthusiasm for participation in the classroom is very full, the back of the form reveals glitz and refraction
