成功的教学活动 ,应捕捉学生学习的兴奋点 ,设计合理的课堂结构 ,才能较为轻松愉快地完成当堂教学任务。几年来 ,我利用“三分钟演讲”的方式启动课堂教学 ,对调整课堂结构 ,提高学生素质起到了推动作用。设计“三分钟演讲”首先是由于学生开课前一两分钟之内不能有意识地控制? Successful teaching activities should capture the excitement of students’ learning and design a reasonable classroom structure in order to complete the teaching tasks more easily and happily. Over the past few years, I have used the “three-minute speech” method to start classroom teaching, which has played a catalytic role in adjusting the classroom structure and improving the quality of students. The design of the “three-minute speech” was first because students could not consciously control it within a minute or two before the class began.
