教师向学生传授知识,需要使用多种工具,其中语言是教师传道授业的主要工具。但是,要想收到事半功倍的教学效果,仅靠有声语言是不够的,还必须掌握和善于运用非语言行为这一强有力的工具。 Teachers impart knowledge to students and need to use a variety of tools, of which language is the main instrument of teacher preaching. However, in order to receive more effective teaching, it is not enough to rely on the vocal language alone. You must also master and be adept at using the powerful tools of non-verbal behavior.
