课堂教学设计是一个动态、系统的过程。教师不可能把尚未发生的课堂教学中的所有可能出现的问题全部进行预设,教学前设计只是一个大概的、初始的框架,教师要结合课堂教学的具体情况进行调整和改变,进行教学中设计;教师要反思自己的教学设计,实施教学后设计。教学中设计与后设计是培养教师反思分析能力,提升教学效果的重要途径和方法。 Classroom teaching design is a dynamic and systematic process. Teachers can not presuppose all possible problems in classroom teaching that have not occurred yet. Pre-teaching design is only an approximate initial framework. Teachers should make adjustments and changes in the light of the specific circumstances of classroom teaching. ; Teachers should reflect on their own teaching design, the implementation of teaching design. Teaching design and post-design is to train teachers to reflect on the ability to analyze, improve teaching effectiveness of the important ways and methods.
