新课程标准实施以来,数学课堂变活跃了,学生在课堂中通过动手操作、小组合作、自主探索等方法主动去获取知识,教与学正在悄然发生变化。如何提高课堂教学的有效性,恰如其分地找到新课程与传统教学的结合点,是一个值得探讨的问题,而有效性的把握需要教师起到导向的作用。 Since the implementation of the new curriculum standards, the mathematics classroom has become active. Students actively take knowledge of the classroom through hands-on operation, group cooperation and independent exploration. The teaching and learning are quietly changing. How to improve the effectiveness of classroom teaching and appropriately find the combination point of new curriculum and traditional teaching is a question worth exploring, but the effective grasp of teachers needs teachers to play a leading role.
