动态生成是新课程改革的核心理论之一。新课程背景下的课堂教学既需要教师在课前精心预设,也需要动态教学资源的有效生成。“预设”是指教师在课前对自己教学的一个清晰、理性的思考与安排。从这个角度说,它是备课的重要组成部分,按字面的意思理解就是指事物的发生和形成。所谓课堂生成,是指课堂教学中的不可预知的发展,即这种发展不是靠逻辑可以推演出来的,它往往表现为“茅塞顿开”“豁然开朗”“怦然心动”“妙不可言”。
Dynamic generation is one of the core theories in the new curriculum reform. The classroom teaching under the background of new curriculum not only requires teachers to carefully pre-class, but also needs the effective generation of dynamic teaching resources. “Preset ” refers to a clear, rational thinking and arrangement of teachers before their class. From this perspective, it is an important part of lesson planning. Literally, understanding refers to the occurrence and formation of things. The so-called classroom generation, refers to the unpredictable development of classroom teaching, that is, this development can not be deduced by logic out, it often appears as “Ma Sedton open ” “suddenly” “ ”Wonderful".
