教学反思:

本课我紧紧围绕“Then and now”的主题,以此主题贯穿整个课堂,不论是在Presentation还是Consolidation环节,都紧密按照时空的“过去与现今”来处理教材。首先我创设情境,导入主题,让学生快速说出下列动词的过去式来热身,一是复习旧知,二是为本课课文学习中要用到的过去式作铺垫。再“See some pictures and say something about me ”老师用多媒体出示关于自己以前与现在的照片,从视觉方面着手,利用照片刺激学生的感官,让学生对于“过去和现在”有个总体印象,同时教授了本课的重点单词“couldn’t”。由此,学生很自然联想到本单元的主题内容,很自然地引出了本课主题。

在文本教学时,我通过多种形式帮助学生学习文本,并借助思维导图在黑板上列出关键词,直观地呈现文本内容,加深学生的印象,帮助学生更好地理解和复述文本,但是学生对于部分单词的读音掌握得还不是很好,如:radio,mobile phone.
