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。
