课堂教学的导入犹如乐曲的引子、戏剧的序幕,起着酝酿情绪、集中注意、渗透主题的作用,也是从课外到课内、由知识向能力过渡的桥梁,在课堂教学中是教学乐章的前奏,是师生情感共鸣的第一音符,是师生心灵沟通的第一座桥梁。 The introduction of classroom teaching is like the introduction of music and the prelude of drama. It plays the role of brewing emotions, concentrating on and infiltrating the theme. It is also the bridge from the outside to the inside and the transition from knowledge to ability. It is the prelude of teaching music in classroom teaching , Is the first note of emotional resonance between teachers and students, is the first bridge of soul communication between teachers and students.
