“预设和生成”是新课程倡导的一个重要理念。预设需要教师的基本功,而生成更需要的是教师的教育智慧,预设是幅不动的画,而生成却是流动的水。生成需要预设的铺垫,预设是成功生成的前提。作者以一节高三一轮复习作业讲评课为例对教学内容进行整合预设并生成。 “Preset and Generate ” is an important concept advocated by the new curriculum. The prerequisites need teachers’ basic skills, and the more wisdom they generate is the educational wisdom of teachers. The presupposition is animated picture, but the generated water is flowing. Generated need to set the bedding, the default is the prerequisite for the successful generation. The author revises homework assignments with an example of a high school and a trimester as an example to integrate the teaching contents and generate them.
