一节成功的数学课离不开学生的参与.教学中我们常会看到这种现象:在教师讲课的时候,学生的目光虽然看着黑板,但是没有焦点,半天都盯着一个地方,或者对待教师提出的问题反应迟钝,没有回答问题的欲望,举手的学生寥寥无几,课堂死气沉沉.学生在被动地学习,没有真正参与课堂活动.教师应想办法启发、引导和指导学生,调动学生在课堂中的参与意识. A successful math class is inseparable from the student’s participation. We often see this phenomenon in teaching: When the teacher lectures, although the students look at the blackboard, but no focus, staring at a place for a long time, or treating The questions asked by the teachers are unresponsive, there is no desire to answer questions, there are few students raising hands, and the class is dead. Students are passively learning and have not really participated in classroom activities. Teachers should think of ways to inspire, guide and guide students and mobilize students in the classroom. In the sense of participation.
