1、精品教学教案五年级语文上册第三单元教材分析本组教材编排了4 篇培养学生科学素养、人文素养的说明文，鲸和松鼠介绍了有关动物的一些知识，向学生开启了一扇探索动物世界的科学之门；新型玻璃介绍了一些新型玻璃的特点和用途，以使学生感受科学技术的神奇和威力；假如没有灰尘揭示了科学家们的重大发现，阐释了灰尘与人类的重要关系。本组教材的几篇课文是以前学习说明性文章的延伸与发展。选编本组教材的目的，一方面是为了让学生了解一些科学知识，唤起学生探索自然、科学奥秘的兴趣，激发学生学习的自觉性；另一方面是要让学生了解说明的方法，体会作者怎样准确地用词、形象地表达，并在习作中加以运用。教学本组教材，应注意以下几点：1.

2、要有拓展课程资源、加强学科整合的意识，一方面鼓励学生利用多种渠道搜集有关信息以扩展知识面；另一方面在科学课教师的帮助下，努力提高学生的科学素养。2.在教学内容上要统筹安排，把课文的学习与口语交际、习作、交流平台和课外书屋有机整合起来。如，一进入本组课文的学习，就推荐优秀科普著作，引导学生阅读，在本组教学即将结束时召开读书交流会；在学习每篇课文时，要指导学生认真做好笔记或卡片，总结从课文中获取的知识和信息，列出课文中运用的表达方法及例子，为“交流平台”中的单元小结做好准备。3.不要把语文课上成科学常识课，对于课文中涉及的一些科学知识，在语文课上不宜深究，应把教学的着眼点放在理解语言文字所表达的主

3、要内容和学习说明文的表达方法上。教学本组教材可用11-14 课时。其中，精读课文4-5 课时，略读课文2-3 课时，“口语交际”与“习作”3-4 课时，“回顾与拓展”2 课时。课题9 鲸课时2 课时精品教学教案课型讲授设计者使用时间一、教材内容分析这是一篇常识性说明文，介绍了鲸的形体特点、进化过程、种类和生活习性等方面的知识。文章既展现了一幅幅关于鲸的生动画面，也向学生开启了一扇探索动物世界的科学之门。这篇课文层次分明，条理清晰，每个自然段基本上讲了一个意思：第1 自然段讲鲸特别大；第2 自然段讲鲸是哺乳动物，不是鱼；第3 自然段讲鲸的种类；第4 自然段讲鲸怎样进食；第5 自然段讲鲸用肺呼吸；

4、第6自然段讲鲸如何睡觉；第7 自然段讲鲸的生长特点。概括起来说，47 自然段分别从四个方面介绍了鲸的生活习性。语言简练准确、平实质朴又不乏生动形象，是这篇课文表达上的一大特点。作者运用列数字、举例子、做比较、打比方等多种说明方法，通俗、生动、准确地对鲸的特点加以说明，融知识性与趣味性于一体，增强了文章的可读性。课文首先拿鲸和人们熟悉的象作比较，使我们形象地了解到，鲸比象还要“大得多”。接着，用翔实的数字来说明鲸的体重，以此来说明鲸“大”。然后，又以我国捕获的一头鲸为例，再次列举具体数字,具体生动地说明鲸的确很大。作者在介绍鲸吃食物以及鲸的生长时，又一次运用列数字的方法加以说明；在介绍鲸的呼吸时

5、，用“花园里的喷泉”来比喻鲸呼吸时喷出来的气形成的水柱，这种打比方的方法，使说明更清楚，也更形象，便于读者理解。选编这篇课文的意图，一是让学生了解有关鲸的科学知识；二是体会作者的说明方法，并学习运用到自己的习作中去；三是培养学生探索海洋动物的兴趣。二、教学目标（知识，技能，情感态度、价值观）1.认识 3 个生字，会写10 个生字。正确读写“目前、上腭、哺乳、退化、垂直、经验、判断、胎生、寿命”等词语。2.正确、流利、有感情地朗读课文。3.了解鲸的特点、进化过程、种类和生活习性等方面的知识，激发学生探索海洋动物的兴趣，培养学生热爱大文档编码:CV7W5V5D10E10 HK8T3R1U4S8 Z
