物理课堂中不可能全都是正式的教学语言。否则课堂的容量过大,而课堂显得没有生气。而“闲话”既不是非说不可的,与教学内容可能也没有过多的关联,比如课堂中两个教学内容的衔接部分。或者是在处理一些棘手的问题中的举例。这些“闲话”可以起到引发学生的兴趣,拓展学生思路的作用。那么教师在组织课堂教学、实现课堂高效时,如何精心设计好题外闲话,让题外闲话“闲而不闲”呢? It is impossible for all physical classrooms to be formal teaching languages. Otherwise, the capacity of the classroom is too large, but the classroom does not seem angry. And “gossip ” is neither nonsense, and teaching content may not have too much relevance, such as the convergence of the two teaching content in the classroom. Or in dealing with some difficult issues for example. These “gossip ” can play a role in triggering students ’interest and expanding students’ thinking. So teachers in the classroom teaching, classroom efficiency, how to carefully design a good gossip, so that questions outside the gossip “free and not idle ” it?
