高三英语词汇复习方法探究 主备人:马继海 讲课教师:马继海
教学目的:2016年高考英语大纲要求学生掌握的词汇量为3000-3500词左右。大纲要求增加阅读中对词义推断的要求。虽然,在平时的学习中,有很多记忆单词的方法,对于每一位即将参加高考的学生来说,如何能在这有限的几十天时间里,提高学习效率,重视词汇的记忆和应用当然是至关重要的。如何能够有效的的记忆和掌握词汇,更需要一些有效的方法,本节课主要通过高三英语词汇复习方法的探究让学生能够结合自己平时的学习,总结出更加有效的词汇复习方法来。 词汇范围:高三英语一轮复习中常见词汇。
学情分析:本班学生为高三理科实验班, 虽然说是实验班。但是班里有三分之二的学生英语基础较差,英语学习两极分化现象比较突出。对于基础较差的学生来说,如何在高三英语复习中,突破词汇复习这一关十分重要。本课将结合本班学生的学习实际,通过任务型教学的方式,和学生总结出一些比较有效的词汇复习方法来。本着对学生负责的原则,力求让学生上完此堂课后能实实在在的学到一点东西。
教学方法:归纳总结,散发思维,合作教学,
创设情境:通过本节课的复习,最后完成一篇语法填空。 授课时间:40分钟 教学步骤:
Tip1:Learn the words according to the word formation. (通过构词法学习词汇。) 语篇填空,要求学生通过阅读小短文,根据文章内容和括号中给出的单词,在空格处填上正确的单词或所给词的正确形式。学生完成填空后,教师引导学生对所填词汇进行进一步拓展,如通过词缀构词记忆等方法,让学生总结常用的词缀。

设计意图:设计意图:①词汇并不是孤立的,每一个词汇都属于相应的词汇群。因此我在此次复习课中尝试在词汇上添“枝”加“叶”,从而让学生进一步巩固词汇及其用法。②英语的造句能力很重要,如果学英语而不会造句子,那么英语水平就会停留在单词的级别上,永远也达不到出口成章,下笔成文的目的,不会造句,语言的学习就是单一的,片面的,缺乏综合运用语言能力的,而且造句是落
