高中英语-Unit-3-Computers-Reading-Who-am-I教学设计-新人教版必修2
Unit 3 Computers一、教学对象分析本节课的教学对象为高一上学期的学生，在经历了必修1的学习过程之后，学生已经对高中的英语学习有了初步的了解和感知，但仍需要训练和提高语篇的理解，归纳和分析的能力。
本节课的一系列活动，就是为学生的语篇阅读打开一扇窗户，培养学生的语篇意识，使其更全面的理解文章内容，归纳主旨大意。
学生在前一节课的词汇学习中，已经掌握了文中所出现的大部分生词，这为本节课的阅读扫清了障碍，能让学生更好的专注于语篇结构的理解，而不必因为生词过多影响阅读效果。
高一学生活泼好动，思维活跃，愿意积极的投入到思考和各种活动中。
这就需要老师积极热情的引导，合理设计活动环节，有条理的分解知识层次，帮助学生循序渐进的掌握语篇的处理能力。
二、教材内容分析本节课阅读材料是本单元的主要阅读篇章，属科普类说明文，讲述了计算机的发展历史及其在当今世界各个领域的应用。
内容较为抽象，且有一些专业术语，对高一学生来说有一定的难度。
但写作手法上以计算机为第一人称进行自白，这种拟人的手法能够激发学生的阅读兴趣，也使得文章更浅显易懂。
本文共分3个段落，以时间为顺序说明计算机的发展历史，且每段的第一句话均为该段落的主题句。
这种结构的语篇非常适合用来启发和引导学生寻找段落的主题句，并进一步归纳文章主旨大意。
同时配以适当的练习，帮助学生归纳总结出方法，在练习中运用这些方法，从而提升对语篇的全局意识，增强对语篇的解题能力。
三、教学目标根据以上学情和教材分析，本节课的重点是教会学生如何正确寻找段落主题句，归纳语篇主旨大意。
以这个任务为主线，贯穿整个教学活动，让学生眼，耳，手并用，通过自主学习，小组学习等教学活动，在语境中观察，总结，实践语篇分析方法，并最终从阅读理解的三个维度达到以下目标：1.信息知识——了解计算机的发展历史及其在当今社会各个领域的广泛应用。
2.语言知识——理解和掌握与计算机相关的词汇。
3.语篇知识——领悟和实践在语篇中寻找主题句的方法，学会归纳文章主旨大意。

高中英语_Who am I教学设计学情分析教材分析课后反思
《Who am I? 》教学设计执教者指导教师学情分析我校高一学生大部分来自于农村，词汇量匮乏，理解能力相对较差；但是他们主动性强，学习积极，经过了初中阶段的英语学习，已经具备了一定的知识储备。
本单元的中心话题是“计算机”，话题虽有趣，但本单元所选语言材料属于科普说明文，内容较为抽象，文章中不乏一些专业术语，对高一学生来说有一定的难度,在教学中应该注意学习方法的指导；另一方面学生基础差，怕说错而不善交流，课堂气氛不够活跃，针对这一问题，在本堂阅读课的课堂设计中，在导入中给出了他们足够的相关词汇引导，鼓励他们多说，多练，让学生在学了这一课之后了解人工智能，展开想象的翅膀预想计算机将来的发展趋势。
效果分析1.通过对科普说明文Who am I?的学习，学生对计算机的演变历史和应用有了基本的了解，激发了学生对科技发展的兴趣。
2.本节课紧紧结合本单元体裁特点，结合学生已有的生活经历和体验创设教学情境，设计课堂活动，激发学生兴趣，调动学生学习的积极性，使学生熟知了计算机的演变历史和应用，并能用英语对自己的观点进行描述。
3.本节课主要教学生运用了略读、寻读等阅读技巧去从文章中获取相关的信息与语言知识，帮助学生很好的理解了整篇文章，同时培养了学生自主合作、分析探究问题的能力。
4.通过本节课的学习，激发了学生对科技发展的热爱之情，进一步提升了学生的爱国情绪。
5.通过合作学习，学生学会了合理想像，并对将来的美好生活充满期待。
6.还有一部分同学不能大方、自如地用英语进行表达，须进一步加强指导及训练。
教材分析内容分析：本节课Who am I? 是新课标人教版高一必修二第三单元的阅读课文。
本单元的中心话题是“计算机”，内容设计计算机的发展历史、计算机的应用等。
计算机这一话题虽然有趣，但本可所选的语言材料属于科普说明文,内容较为抽象，文章也不乏一些专业术语，对高一学生来说有一定的难度。
不过，本篇课文以计算机为第一人称进行自白，自述其发展演变的历史以及计算机在当今世界各个领域的运用。
