Learning about Language多媒体教案及点评

人教版

Unit3 Computers Learning about language的教学设计

一、教材分析

1．新颁布的《英语课程标准》明确指出此次英语课程改革的重点就是要改变英语教学过分重视语法和词法知识的讲解与传授，忽视对学生实际语言运用能力的倾向。强调从学生的学习兴趣、生活经验和认知水平出发，倡导体验、实践、参与、合作与交流的学习方式，发展学生的综合语言运用能力。因此，在教授语法时，我们教师不应采取满堂灌的教学模式，而应将语言的形式与意义和真实情景结合起来，使学生在实际语言运用中内化语言规则。本课的设计即以此为本，旨在给学生提供一个观察，发现，体验、实践而***台。

2．本课学习的内容是人教版新课标BOOK2 Unit3 Computer的Learning about language 中的一个课时。考虑到教学内容较多，既包含新词汇的学习和巩固，副词的运用，又包含语法的讲解，一节课很难落实教学目标；从学生的实际情况看，现在完成时的被动语态虽然在初中曾经出现，但不做要求，所以学生掌握的情况不好。基于这两点考虑，笔者对教材进行重组，把Learning about language中的语法课单独作为一个课时，以加强学生的理解和应用。因此本课语法教学将对掌握好这一模块语言知识及交际活动的顺利进行，都起着支持的作用。

二、学情分析

1．教学的对象是高一学生，英语水平程度上有较大的差异，一小部分同学确实掌握的不错，从而可能对这课学习没有很强的兴趣；大部分学生还不太明确；还有一小部分学生根本不知道是怎么一回事。这给教学带来较大的挑战。我在教学中针对不同学生的不同需求，不同水平学生的不同特点，设置各种活动，有个体活动和交互活动，有机械操练和实践性及创造性活动，循序渐进，期望不同层次的学生都能学有所得。

2．高一学生思维活跃，敢于提出不同见解，三年的初中英语学习，使学生储备了一定的词汇和英语知识，能较好地展开话题讨论，各抒己见。我采取多媒体教学，运用多种教学方法和手段激发学生交流和学习的兴趣，希望学生始终处于积极、主动的思考、探究和创造的状态中，创造充满活力的课堂气氛。

三、设计思想

（一）设计思想

高中的语言教学不仅是必要的，而且是打基础的最重要的阶段。但是语言教学不是目的，而是为了掌握和应用语言服务的，即

“Learning by doing”。这堂语法课遵循二语习得的理论和中国学生的语言认知规律，变传统的接受式教学法为“发现－体验－探究－合作”式教学法，即以4P语法教学(preparation, presentation, practice, production)组织课堂，主张课堂教学应该指导学生在充分体验语言材料的基础上，即充分的语言信息输入的基础上，归纳有关语言知识和语言技能。在设计思路上充分考虑到学生的生活经验和兴趣，为学生精心设置各种情景，通过一系列的任务活动，达到有效的语言输出，即语法应用能力的培养。

（二）设计特色：以计算机为话题，遵循学中用，用中学的原则。创设情景让学生发现，体验而习得语言，并在学生的博客上运用语言，学生学得快乐，有

效果。

四、教学目标

1．语言知识目标:准确读出重点单词和短语，准确说出其基本意义并在设定情境中就其基本用法展开运用。

2．语言技能目标：表达与电脑和智能机器人相关话题的态度和观点。

3．情感态度：学生能自如地表达自己的思想，情感以及与人合作交流的能力。

4．学习策略：通过主动语态和被动语态的比较，以及现在完成时的应用培养学生的认知策略；引导学生对自己学习过程，学习困难等进行分析，培养学生的调控策略；鼓励学生运用重点单词和短语，准确说出其基本意义并在设定情境中就其基本用法展开运用. 5．文化意识:让学生了解计算机的优缺点，正确使用计算机。

五、重点难点

1．教学重点：准确读出重点单词和短语，准确说出其基本意义并在设定情境中就其基本用法展开运用,如何正确对待和使用电脑。

2．教学难点：表达与电脑和智能机器人相关话题的态度和观点,通过合作交流表达思想和情感。

六、教学策略与手段

本课教学强调从学生实际情况出发，从学生生活经验出发，而不是从“本本”出发。以学生为中心，让学生成为课堂中的主角，教师成为教学活动的组织者，合作者和参与者。在设置任务的过程中，考虑到了生生互动，师生互动。学生在教师特意创设的教学情境如直观情境，合作情境和活动情境等中去学习语言，体会英语语言的特点，使语法学习能在一种活的环境中轻松愉快地进行。通过发现，体验自然习得语言知识,取得良好的教学效果。

七、课堂教学过程设计：

Step 1Discussion and Lead—in T:Q1:How do you often use computer when you go home? S: Play games communicate with others surf Internet Listen to music watch movies read news Buy the things I like, eg: books and CDs Learn English Download(下载) information from Internet I often use a computer to and I never use it to… I sometimes use it to…

设计说明:由师提出两个问题结合图片导入新课，复习课文，激发学习兴趣

，计算机，高中生最感兴趣的话题之一。兴趣使学生积极大胆参与和教师地交流，在谈论计算机的用处时，为感知体验做好铺垫。这个环节的设计，是尊重学生已有经验的体现，也是对英语学习有困难的学生的关心。
