教师讲、学生听,教师问、学生答的传统的数学教学模式早已被广大教育工作者所摈弃,但现在的课堂大力倡导学生活动,似乎“热热闹闹”的讨论、交流、展示就是新课改的全部,而忽视了教师在教学中的主导作用,我认为是从一个极端走到了另外一个极端.事实上,提倡动手实践、自主探索、合作交流的学习方式和教师在课堂教学中发挥主导作用并不矛盾,不论用什么样的教学方法,教师的主导作用永远不可忽视. Teachers say, students listen, teachers ask students to answer the traditional mathematical teaching model has long been rejected by the majority of educators, but now the classroom vigorously promote student activities, it seems “lively” discussion, exchange, display is New Curriculum Reform, while ignoring the leading role of teachers in teaching, I think it is from one extreme to the other extremes.In fact, to promote hands-on practice, independent exploration, cooperation and exchange of learning styles and teachers in the classroom teaching To play a leading role is not contradictory, no matter what kind of teaching methods, the leading role of teachers can never be ignored.
