课堂教学是师生、生生之间的相互碰撞、相互接纳的过程,也是师生之间、生生之间真诚交往、共同探讨,获得知识的互动过程。由于数学活动的开放性较强,在课堂上学生的思维旁逸斜出,即使课前预设再充分,一节课也会出现节外生枝的现象,遭遇一些始料未及的问题。其实,“课堂意外”是学生真实的流露,是学生个性的张扬。
Classroom teaching is a process in which students and teachers collide with each other and accept each other. It is also an interaction process between teachers and students, sincere exchanges between life and life, and common exploration and acquisition of knowledge. Due to the strong openness of mathematics activities, students are inclined to leap out of their thinking in the classroom. Even if the pre-class preset is sufficient, there will be extracurricular events in a class and encountering unexpected problems. In fact, “classroom accident ” is the real disclosure of students, is the individuality of the publicity.
