课堂教学是一门艺术,因此不同的教师与不同的学生,虽然用相同的教材,但每个课堂又不尽相同。同时课堂教学又是一门科学,做为一门科学,又有它内在的规律可寻。课堂教学中教师的角色是多样与复杂的,他好比是一个策划、编导,又好比是一个优秀的演员,还是一个优秀的评论员。每一节课堂就好比是一个舞台,是一台戏,教材好比是剧本,学生与教师好比是演员,讲台就是舞台。因此要建构好一堂有效的课堂教师就要做好精通剧本内容,了解自己的演员素质,设计好每个环节,让这处戏演的生动,活泼而有效。 Classroom teaching is an art, so different teachers and different students use the same teaching materials, but each class is different. At the same time classroom teaching is a science, as a science, but also its inherent laws can be found. The role of teachers in classroom teaching is diverse and complex, he is like a planning, director, and is like a good actor, or a good commentator. Each section of the class is like a stage, a drama, textbook is like a script, students and teachers are like actors, the stage is the stage. Therefore, in order to construct an effective classroom teacher, it is necessary to be proficient in the contents of the script, to understand the quality of the performers themselves, and to design every link so that the performance is vivid, lively and effective.
