传统的数学课堂教学通常以例题、示范、讲解为主要方式。在客观上形成学生只能被动接受,因此课堂中几乎看不到猜想、实验,观察、推断等学生亲身体验的实践探究活动。课堂教学是充满生命力的活动。新课程的课堂教学,将由传统的封闭走向现代的开放,由教师主宰 Traditional mathematics classroom teaching is usually based on examples, demonstrations, and explanations. Forming the students objectively can only be passively accepted. Therefore, in the classroom, there is hardly any practical inquiry activity such as guessing, experimentation, observation, and inference. Classroom teaching is a life-filled activity. The classroom teaching of the new curriculum will be changed from the traditional closed to the modern one, dominated by the teachers.
