Using LanguageⅡ课堂实录及点评

Unit2 Cloning Using language教学设计

广西岑溪中学

张鸽

一、教材分析

本单元以Cloning为话题，旨在通过单元教学，使学生了解克隆技术的优缺点，学会表达和支持个人观点，能用所学的有关Cloning的词汇去表述自己对这一新技术的观点和看法。

语言运用（Using language）部分提供的材料THE RETURN OF THE DINOSAURS?是一篇介绍克隆是否可行的说明文，具体介绍了动物克隆的历史以及克隆濒危或已灭绝动物的限制，旨在帮助学生进一步认识克隆的意义。从话题内容上分析，可将Using language和writing整合在一起，设计成一节任务型“阅读写作课”。

二、学情分析

我所带的两个班级的学生英语基础一般，平时较少阅读科学题材的文章, 知识面相对狭窄，阅读理解这篇文章还是有一定难度。但学生的好奇心和学习接受能力比较强，可以布置学生课前上网或去图书馆找出一些有关克隆的资料，并与多媒体相结合简单介绍克隆及克隆技术的一些知识，让学生有了一定的知识准备以利于很好的理解课文。

三、设计理念及教学目标

这节课的主要目的是培养学生阅读和写作技巧，使学生学会准确分析阅读问题，懂得从文章中找到关键句子摄取必要的信息，从文章信息提取整合出自己的思想，讨论并就克隆形成自己的见解，付诸笔端成文。
