上课,尤其是上公开课,很多教师都害怕出现“冷场”现象,害怕被学生晾在一边唱独角戏。由此,不少教师在教学中不是设计一些学生不用思考即可解答的问题,就是把有思维容量的综合性问题支解成若干琐碎的小问题。学生似乎也很善解师意,总能不假思索地接住教师抛过来的“问题球”。如此,在课堂上,常常会呈现出一幅“生动”的画面——师生间一问一答,教学中你来我往,课堂流程连贯而顺畅。 In class, especially in the open class, many teachers are afraid of the phenomenon of “cold field”, afraid of students being sing in one-man show. As a result, many teachers do not design some questions that students can answer without thinking in their teaching. That is to say, the comprehensive problem of thinking capacity should be solved into a few trivial problems. Students seem to be very understanding of the teacher, always able to catch the teacher throwing the “problem ball” without hesitation. In this way, in the classroom, often a “vivid” picture - a question and answer between teachers and students, teaching you to me, the flow of the classroom coherent and smooth.
