普通高中课程标准实验教科书英语必修2
UNIT3COMPUTERS设计说明:
本单元是新课标高中英语必修2unit3,中心话题是“计算机”,本稿设计的内容是热身和阅读两部分,分两课时完成。
为了让学生在学习课文之前能够充分热身,对探究计算机的发展演变过程产生浓厚兴趣,热身部分不仅有丰富的图片及易懂的文字介绍,而且有可行的词汇学习和话题让学生进行讨论,这样能让学生充分热身顺利进入下一环节——阅读。
由于有了热身部分的充分准备,学生对计算机的了解增加了不少,而课文导入部分出乎意料的设计,能够引起学生极大的兴趣,因而他们在阅读课文时就不会感到枯燥,即使有困难如部分生词也能积极去克服和思考。
值得一提还有两个课时的作业布置都是基于课堂活动内容,既是对所学内容的小结也是课堂活动的延续,而且这也符合新课标所倡导的教育教学理念。
