Unit4 Lesson2 公开课教学设计
教材：北师大版必修二Unit 4 Lesson 2
课题：Apps
课型：视听说课
主题语境：人与社会—科学与技术
授课时长：60分钟（第一课时）
文本分析：
【What】
本节听说课的文本以访谈对话的形式呈现，围绕单元话题“信息技术”，讲述软件应用开发者Li Xing回答采访中有关应用程序的一系列提问，包括应用软件流行的原因、教育类应用软件的功能和研发软件的困难。
【Why】
编者希望学生通过听这段对话，了解应用软件的功能和用途，感受科技带给人们生活的便利，认识到科技对于改变人们生活的意义和价值。
【How】
语篇特点：
此文本以访谈对话的形式呈现，因此采访者和被采访者是以问答的方式进行。在之后的活动设计中，教师要引导学生根据听力语篇的特点，采用相应的听力策略。对于采访类的文本中，教师可引导学生先关注采访者提出的问题，迅速获取文章的主要信息，再让学生关注每个问题下的细节信息。
语言特点：
为了让学生了解应用软件的功能和用途，感受它给人们生活带来的便利，Li Xing在接受采访的过程中，使用了一些描述应用软件流行和介绍应用软件功能的目标语言，比如：
在描述应用软件流行的原因时：
Well, apps are very useful. They help us find popular restaurant, call for taxis, find directions to different places, and so on.
在描述教育软件的功能和用途时：
Educational apps are becoming increasingly powerful. For example, some apps allow students to choose their online teachers and subjects according to their personal interests and needs. They also ensure that students can all enjoy the same learning materials, even when they’re not sitting in the same classroom together.
以上描述应用软件功能和用途的语言有必要让学生予以关注，并设计新的情境让学生进行内化和语言。同时，从以上语言可以看出，Li Xing的表达逻辑性强，有主题句，有细节支撑，值得学生学习和借鉴。
学情分析：
本节课的授课对象是北京市重点高中的高一学生，学生基础较好。
学生在日常生活中经常使用应用软件，已经成为学生生活中不可缺少的一部分，因此对应用软件这一话题比较熟悉，并具备一定的使用知识。但是对于应用软件类的英语文本接触很少，而且随着中外交往的需要，学生应具备一定的能力去用英语谈论和介绍常见话题。但是教师发现当学生介绍应用软件的用途时，学生还是会遇到一些困难：经过前期的调查（对课前作业的分析），大部分学生在描述应用软件用途时，学生只能泛泛地谈及其用法，使用的语言也比较单一（help us do…; we can use them to do…）；部分学生表述的逻辑不清晰，不能有理有据的进行介绍。
而教材提供的听力文本中，介绍应用软件功能和用途的内容不够丰富，相应的目标语言也不够丰富。为了让学生了解更多的应用软件使用方面的内容，让学生使用准确和丰富的语言进行表达，教师补充了相关的视频资源，具体介绍了三款应用软件（旅行类、饮食类和社交类），以帮助学生了解更多的应用软件相关知识，并且积累介绍应用软件功能和用途的目标语言，为最后的输出活动进行铺垫。
此外，通过问卷发现，在下载一款手机应用软件时，学生较多考虑的是实用性和个人兴趣，很少考虑该应用软件是否会带来安全隐患，因此教师补充了国外一个研究机构就当前流行软件的安全性所出示的研究报告。希望引发学生对手机应用软件的安全性问题的思考，并且在行为上做出相应改变，能在日常生活中合理使用手机应用软件。（因为时间的关系，此部分作为课后作业）
学习目标：
在本课学习结束时，学生能够：
提取和复述听力文本中的主要信息（包括应用软件流行的原因、教育类应用软件的功能以及研发软件的主要困难）；运用听力文本中相关语言谈论生活中最常用的应用软件的功能和特点；
获取和介绍视频中的三款软件的功能和特点，并能对这三款软件做出功能上评价；
向外国交换生推荐一款方便好用的中国手机应用软件；
关注到手机应用软件的安全性问题，并就如何合理地使用手机应用软件发表看法。（家庭作业）
课前任务：
1. 学生完成了一份关于手机应用软件使用情况的调查；
2. 学生以“我最喜欢的一款手机软件”为题，完成一篇小作文。
