常常听到教学一线的音乐老师说教学公开课表演成分太多,而在真正的教学中根本无法做到。究其原因,是公开课多为精心准备的集体智慧,只需展示精彩的教学过程即可;学生大多以表演者的角色参与,课堂秩序显得井然有序。但在日常教学中,教学一线的教师不仅要教,还要去维持课堂秩序, It is often heard that the music teacher in the teaching line says that there are too many performance components in the teaching open class, which cannot be achieved in real teaching. The reason for this is that open classes are mostly well-prepared collective wisdom. Only the wonderful teaching process can be demonstrated. Students mostly participate in the role of performers and the order of the classroom is orderly. But in everyday teaching, teachers in the front-line teaching must not only teach but also maintain order in the classroom.
