课堂教学既要有事先的认真预设又需要有恰当的动态的生成,没有生成,课堂就是机械的操练,没有积极有效的预设,课堂就是胡乱无序的热闹。如何处理好预设与生成的关系,就成为新课程背景下摆在教师面前的实际问题。 Classroom teaching requires both pre-conscientious presupposition and proper dynamic generation. There is no generation. Classrooms are mechanical exercises, there are no active and effective presuppositions, and classrooms are riotous. How to deal with the relationship between presets and generations becomes a practical issue for teachers in the context of the new curriculum.
