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。
