二、学情分析

学生学了一年半的英语,对英语有了一定的兴趣与基本的概念。我认为,保护学生的学习信心,引发学生的深层学习兴趣是本学期英语教学的重中之重。所以,教师在课堂上一方面提出了适合学生完成的任务,并在课堂结尾及时给了学生展示的平台,让学生能够通过努力达成目的,并体验成功的欢乐;另一方面,尽量营造真实的情境,利用学生好奇、爱思考、爱想象等心理特征,设计各种趣味性强又有一定挑战性的语言含量丰富的活动,大力激发学生的学习兴趣。

在英语学习的初级阶段,引导学生主动学习、自主学习,养成良好的学习习惯也非常重要。采取了有效的评价措施能确保学生在保持高昂的学习兴趣的同时,主动积极学习。另外,为了引导学生形成良好的语感,教师在课堂中贯穿自然拼读法的教学。同时,在激发学生旧知的同时,增大语言的输入量,创造了各种平台让学生运用语言,给学生多实践多运用的机会,让学生可以在运用中不断提高语言能力。本班学生基础较好,初步掌握了自然拼读的规则,有一定的英语思维能力,针对这种情况,教师在设计中适当拓展了课本内容。

三、单元重、难点

教学重点:能够掌握与天气有关的词与相关句型,并运用它们在真实情境中进行天气主题的交流,用相关主题的语言知识做事情。

教学难点:阅读与天气有关的主题文章,并理解与之相关的一些拓展语言知识。

四、教学过程

活动1【导入】Warmupandpresentthetask.

Greetings.

Listen to a song: There is a thunder.

Present the task of this unit:

设计意图:在课堂伊始引导学生唱英语歌,营造轻松愉悦的英语学习氛围。本课时选取的一首英文歌与天气有关,带领学生尽快进入本节课的主题学习。在此环节引出本课时的任务:应聘做校园气象站的英语播报员。任务的布置让学生明确学习目标,自主学习。在布置任务的同时还进行了情感的教育。

活动3【活动】Engagement

Challenge2: Thinking game.

1. Present two maps and a short passage:

Teacher: The weather station uses some colours to express temperature.

Look! Let’s read the short passage.

活动4【练习】Summary.

Practice in groups of four.

Choose some students to have a show.

设计意图:学习语言的目的是为了真正做到在真实语境中交流,或者用英语做事情。在本环节,老师引导学生尽量真实用英语做事情:做一个天气播报。在完成任务之前,老师先自己示范,并创造机会让学生大量使用目标语言,为顺利完成任务夯实基础。学生在合作完成学习任务时,继续大量运用目标语言进行实践运用,形成用英语做事情的能力。
