试述在教学中如何处理“预设与生成”的关系。

答案：

本题解析：

首先，辩证地理解“预设与生成”的关系，既要改变过去那种只有“预设”，完全封闭，一切尽在“教师掌控之中”的现象，又要避免不适当地、漫无边际地“生成”，影响课堂教学质量，减损国家要求及教育“引导”“塑造”的责任。

其次，教师在备课及进行教学设计时，要“详略得当”。所谓“详”，一是在教学目标和内容的设计上,尽可能地将“三维目标”和有关内容加以整合，而不能仅有“知识点”；二是尽量考虑周到，预先设想可能出现的情况及多样化的对策。所谓“略”是指教案不要太详尽，宁可“粗一点”，给现实的、活生生的教学留下一定的时空,最终在教学中完成，在教学后完善。决不能像过去那样把教学的每一环节，教师的每一句话及学生的可能回答都写出来，使得原本富有生命力的教学成了完全预定的、僵死的“走教案” “演教案”。

再次,在课堂中,教师要“与时俱进” “与境俱进”，及时抓住并灵活处理具有“生成价值”的问题、回答、细节、情境等，让教学充满灵动、智慧与活力。但是，这种“生成”必须与预设的学习目标、学习主题有某种内在联系(这种联系不一定局限于本节课或本单元的目标和内容），或是拓展,或是深化，这样才能既保证课堂教学的“开放”与“灵活”，促进学生自主和富于个性化、创造性地学习，又达到了国家对青少年一代的基本要求。
