Computer---Learning about language教学设计

陈明霞

一、教材整体分析

本单元的中心话题是“计算机”，内容涉及计算机的发展历史、计算机的应用等，其中还谈到包括计算机在内的几种信息技术的载体、智能计算机的发明等等。不过，整个单元多以计算机为第一人称进行自白，这种拟人的手法使得文章谈起来妙趣横生，抽象的专业知识介绍起来也浅显易懂。本节课是阅读课后面的练习和语法---现在完成时态被动语态。

二、学生情况分析

计算机这一话题虽然有趣，但本单元所选语言材料属于科普类说明文，内容较为抽象，文章中也不乏一些专业术语，本节课语法对于高一学生来说有一定的难度。

目前，学生上课以interpersonal的交流为主，而interpretative和presentational形式比重不够。由于文化教学不够重视，学生的跨文化意识不高。此外，学生跨学科学习的意识不够，语言和信息的双向促进关系的认识不够。对于比较策略主要运用在英汉汉英互译的语言层面，未进入文化比较和思维比较。学生的课外语言活动环境不够丰富和重视程度不够，通常以词汇、语法和写作练习为主，缺乏真实的语言运用。
