英语人教版四年级下册Unit 3 Weather -Lets Spell.doc

教学设计陈懿 博罗实验学校 四（5）班级PEP4 Unit 3 Lets spell、人民教育出版社、第三课时、Lets spell一、教学设计（一） 教学目标1 语言知识学生能够掌握ar和al的发音规则，并能正确发音，分辨出两种发音的区别。2. 语言技能学生能够读出符合ar,al发音规则的单词，能根据发音拼写出符合ar,al发音规则的词；学生能理解含ar,al的单词意义并造句；学生能够在篇章，并见词能读；学生能根据熟悉的旋律，大胆唱出所学的知识。3文化意识 培养小组合作精神，发扬互助友爱的良好品德。4情感态度培养学生用发音规则拼写单词的兴趣；增强学生大胆读单词的自信心；以及热爱拼写的情感态度。5. 学习策略教师通过创设情境启发，引导学生自主探究、思考、讨论、交流学习成果。以旧知识为基础，学生自主发现规律，从而掌握所学知识。（二）教学内容分析1教材内容的地位、作用与意义 本课时是人教版PEP4下册中第三单元Weather的第三课时，关于字母组合ar,al的语音知识。在掌握了26个字母的发音和大小写的书写形式，同时也掌握了辅音字母最简单的发音规则以及五个元音字母短音的发音规则。本学期接触过相关组合发音如er, ir,ur等的组合长音发音特点，也认知了字母组合在单词中间单词，因此本单元的学习是上个单元的承接，让学生能继续学习长音。从发音嘴型分析，学生首先接触扁型发音，进而学习嘴巴张大和双唇圆型发音，为接下来的第五单元做好铺垫。2教材的编排特点、重点和难点 本单元是在学习了长音和双唇扁型发音的基础上，增加了双唇圆型发音的特点，为两种发音特点作了过渡性衔接，同时为下一单元做好铺垫。 重点在于学习ar,al的发音特点和规则，了解ar,al在单词中间的一般性发音。 难点在于正确辨别两种发音。（三）教学对象分析1学生已有知识和经验 经过三个学期的学习，四年级的学生已经掌握了26个字母的发音和大小写的书写形式，同时也掌握了辅音字母最简单的发音规则以及五个元音字母短音的发音规则。学生能够通过自然拼读法拼读简单的单词，且学习积极性高，趣味性强。2学生学习方法和技巧 以旧知识滚动新知识，自我发现探索；小组合作，共同发现问题，共同解决问题。3学生个性发展和群体提高 大部分学生缺乏学习自主性，常规学习是老师总结，学生领取老师所给的知识总结，而通过自我探究学习，增强学生的自主性，自我学习，自我总结和发现； 群体合作，如小组学习，在我校是一贯实施并坚持的，而小组合作精神仍有待提高。通过小组成员共同探究，练习，学习，将个人力量汇聚，从而将群体成效显著化。 （四）教学策略与过程1教学设计思路 根据学生的学习特点和兴趣爱好，本课以学生最熟悉的字母a为引子，不开心的a走在路上，遇见会说话的盒子，引出学生已掌握的单词walk和talk，设置了让学生帮助a找朋友的任务，将本课要学的ar, al 组合自然呈现。再以找朋友为奖励机制的基础，激发学生提取旧知识，将学过的含ar, al单词拼读出来。通过小组合作，整体操练，个别抽查和游戏中，学生在拼读中获得乐趣。继而通过肯定和赞扬，鼓励学生乐于助人，帮助Mark获得快乐的同时，也掌握了单词在文章中的运用和理解。从字词句篇曲，全面将本课知识整合，学生能在自我发现，探究，解决，掌握，运用中，获得快乐和自信。此外，在评价方法的选择上，我采用了小组评价和个人评价相结合的评价方法，极大地调动了学生的学习热情，让学生乐中学，学中乐，共同体验拼读所带来的美妙乐趣。2教学过程（步骤、目的、教师活动、学生活动、媒介运用） 见附件一3板书设计 见附件二（五）教学评价 本节课整理环节流畅，知识由浅至深层递进； 以字词句篇曲引导学生学习、掌握知识。 学生学习能力得以突出，学生真正掌握本课要点并很好地完成各项任务； 学生在快乐中获取知识，做到了每人开口，每人参与，每人成功。二、教学反思1整体评价 本节课整理环节流畅，知识由浅至深层递进； 学生学习能力得以突出，学生真正掌握本课要点并很好地完成各项任务； 教师对客房把控能力强，有丰富的师生互动，生生互动环节；2亮点 以旧知识滚动新知识，学生在自我探究中寻找到了发音规律；由字词句篇曲的环环相扣，充分激发了学生的学习力和创造力； 游戏环节新颖，BINGO game的操作，不仅能训练学生听音写词，同时还锻炼了学生造句能力和理解能力； 篇章朗朗上口和喜闻乐见的旋律，让学生在乐中学。3问题 个别纠音较少； 学生个性特点未充分发挥； 游戏环节气氛未能足够活跃；附件一：教学过程教学过程步骤内容目的教师活动学生活动媒介运用1Greeting and Phonics song.To cheer them up.(1)Greets with Ss:Hello, boys and girls.
