教后反思:
在高考阅读中,常常会出现对文中单词或词组词义的猜测,在平时的阅读教学中如何渗透对学生这一方面能力的培养,也是教师应该思考的一个问题。平时有意识地培养猜词的能力,根据词根,上下文等,尤其要注意单词及词组在上下文中的含义,而不是仅仅它的字面含义。同样,在高考阅读中还经常会有深层理解题,如Whatcanyouinferfromthesecondparagraph?所以阅读的要求不能仅停留在表面含义,更应挖掘文章潜藏的内涵。在教学中,也应充分应试技巧的训练和培养。这节课也有一些亮点,比如:1.这节阅读课上出了英语新课程标准的理念。在阅读之前先对文章内容进行预测,这符合阅读的一般规律,在阅读之前首先在头脑中形成一个信息包,为阅读做好准备。
2.这节阅读课把应试教育和素质教育结合起来了。首先,在阅读时注重篇章的理解,帮助学生理解文章结构(Briefintroduction,BodyandConclusion)。其次,难句的突破在课文理解中带出,不是为了难句去讲难句。
作为杰出的教学工作者,能够保证教课的顺利开展,教师要准备好教案,这是教师工作中的一部分。教案可以让学生能够在课堂积极的参与互动,帮助教师缓解教学的压力,提高教学质量。你知道如何去写好一份优秀的教案呢?为此,小编从网络上为大家精心整理了《Teaching plan of Book 5 Unit 1 Great Scientists英文教案》,欢迎您阅读和收藏,并分享给身边的朋友!
