学习好资料欢迎下载恐龙的灭绝教学设计及反思恐龙的灭绝教学设计及反思兼谈教案的预设性和生成性执教恐龙的灭绝 之后，对教案的预设性和生成性有了更深的感性理解。现就教案的这“两性”问题作一反思性总结。正式上课之前，我精心设计了以下预设性方案。【教学内容】恐龙的灭绝是人教版语文课标实验教材二年级下册的一篇科学知识小品文。课文例举了恐龙灭绝的五种富有代表性的假说，引起人们深思：“为什么今天的人类只能在博物馆或者从电影和书籍中，来想象恐龙往日的辉煌了”？【设计理念】科学小品文一方面要使学生获得科学知识，更重要的是激发学生对自然现象进行科学探究的兴趣和愿望。从科学小品文的特点和学生对科学的好奇心出发，我以“课内得法，课外受益”为指导思想，抓住文本解读和延伸拓展两大版块，通过环环相扣的流程，进行探究性学习。探究性学习以“活”和“动”为总特征。“活”表现为学生的积极性和主动性；“动”表现为学生真正动手和动脑。通过探究的方式来学习，以训练学生的语言和思维能学习好资料欢迎下载力，激发学生的探究兴趣。【教学目标】通过探究性学习方式，师生一起带着疑问阅读课文，在想象中漫游恐龙王国，在漫游中轻松愉快地朗读课文，达到正确、流利的程度；同时激发孩子们对科学的好奇心，有对恐龙的灭绝等自然现象进行科学探究的兴趣和愿望。【教学过程】一、设置问题情境，引导说话质疑1、展示交流学生收集的资料（以恐龙灭绝的原因为主）。2、播放教学视频恐龙的灭绝。3、出示“恐龙骨骼化石及其复原”的图片，渗透“太阳系考古是获得具体证据”的科学途径。二、默读研读课文，弄清假说理由1、关于恐龙灭绝原因课文中有几种说法？其理由是什么？2、弄清恐龙灭绝的直接和间接原因，并能用小标题概括五种假说。（“冷说、撞击说、偷吃说、传染说、降温说”可采用抓关键词的方法概括）3、连线题（巩固课文内容）：地球上的条件变化引起一些事物的变化结果地球变得十分寒冷偷吃恐龙蛋宇宙行星撞上地球恐龙耐不住严寒恐龙灭绝地球上哺乳动物增多尘埃遮住太阳，文档编码:CP8S6E9M2B3

填表”，在实施过程中因时间耽误没能在课堂中进行填写，只能放在课后完成。这虽然是个遗憾，但我以为课堂应以学生为本，从学生的发展着眼，学生课堂上真正弄懂了恐龙灭绝的原因，理清了因果关系，会抓住关键词概括小标题，完成“填表”任务易如反掌。课堂中填表和交流完全可放在下节课去完成，千万不能为了完成自己的预设方案牵着学生鼻子走。有的老师在评课时提出：课伊始，就让学生按照这份表格读书、填表，小文档编码:CP8S6E9M2B3

本配套读本，让孩子在课外大量阅读。他们每周也只安排了一节课外阅读指导课或交流课，重在学习方法上的点拨和阅读兴趣与阅读习惯的培养（当然还开展了系列读书活动）。并没有完全置语文文本于不顾，只做舍“本”逐“配”的工作。课堂的时间是宝贵的，应选择精神丰富的大餐供学生享用，不能让学生吃一肚子垃圾快餐而倒了胃口。听课教师说我的拓展材料太多，让学生来不及细看，连教师都目不暇接。对事先没有接触这些材料的人来说，速度确实快了些。我是这样考虑的：起初我只打算放一篇恐龙灭绝种种假说的综合性
