Using LanguageⅡ特级教师教学实录

高中英语人教新课标选修九Unit 4 Using Language教学设计

一、课程名称

人教新课标选修九Unit 4 Using Language---Flowers and Their Animal Pollinators

二、教材及教学内容分析

本单元为人教新课标选修九Unit 4，中心话题是“自然界中的植物、植物探索的历史”。本单元的语言技能和语言知识都是围绕“自然界中的植物、植物探索的历史”这个中心话题来设计的。本课时以Using Language---Flowers and Their Animal Pollinators 为授课内容，主要介绍了虫传媒和鸟传媒两种方式，叙述了再进化过程中异花传粉逐渐被选择、发展，自然界植物传粉的方式是进化过程中形成的适应环境的现象，与繁衍后代有密切关系。通过这一课时的学习，让学生结合所学的生物知识加深对虫传媒和鸟传媒的认识，激发学生对植物及其传粉方式的兴趣！

三、学情分析

本节课的教学对象是高三学生，他们已具备一定的生物知识，对动物传媒有一些了解。他们具有活跃的思维，具有一定的用英语分析和解决问题的能力。虽说普通班的学生有很多英语基础并不太好，思维能力和英语表现力不佳，但他们也都渴望得到老师和同学们的理解和认可，所以只要设计出适合他们认知能力和让他们感兴趣的课，就能调动全班同学参与到教学活动中来。

十、教学效果及反思

总的来说，本节课基本上达到了教学预期，做到了激发学生兴趣，发挥了学生的主观能动性，提高了学生用英语思维的能力和用英语表达的能力，培养了学生多方面的素质。

5

1.

本节课使用了多媒体，展示了大量精美图片和视频，并设计了许多难度不大的活动，为学生创造了良好的学英语环境。调动了学生学习的积极性，提高了他们自主探究的能力。学生参与积极性高，体现了“以学生为本”的理念。

2.

课堂设计适合本班学生水平。教师成为学生学习的组织者、指导者和帮助者，除了教授学生必要的语言知识外，还很重视学生的兴趣和能力培养。

3.

以任务型教学为原则，整堂课师生互动，生生互动，每个任务都围绕着学生“学习”为出发点，学生每个活动都有明确的目的指向和具体要求，大量输入后有所产出。让学生品尝到学习英语的成就感。

不足之处：

1.

学生思考、讨论和回答的基本都是老师设定好的问题，应留出一些时间让学生提出自己的问题。

2.

学生评价方式单一，基本是教师评价学生。若是留些时间让学生自评，互评，相互学习，效果会更好。
