新课程理念中的“预设”与“生成”是一种新的概念,其中,“预设”是指教师在教学之前的计划、安排,主要体现在课前的准备活动中,比如设计教案、导学案等。而“生成”则是指课堂上,师生互动过程中对某个事物或现象的一种动态认识,从而生成新的课堂。某种意义上说,教学过程中没有了预设,就没有好的生成结果。当然,如果过分强调预设,则会使整个教学程序化严重,无法激起学生的好奇心与求知欲,更谈不上高质量的生成效果。 In the new curriculum concept, “preset ” and “generate ” is a new concept, in which “preset ” refers to the teacher before the teaching plan, arrangement, mainly reflected in the preparatory class Activities, such as the design lesson plans, guided studies and so on. And “Generate ” refers to the classroom, a dynamic understanding of a thing or phenomenon during the interaction between teachers and students to generate a new class. In a sense, there is no preconceived teaching process, there is no good result. Of course, over-emphasizing the presupposition will make the entire teaching process serious and can not arouse the students’ curiosity and curiosity, not to mention the high-quality generating effect.
