论文部分内容阅读
一、引言
《普通高中英语课程标准》对高中阶段的词汇量提出了明确要求,与之相应的现行教材的词汇量也大幅增加,给词汇教学带来了很大的挑战。对于缺乏听说环境的中国学习者来说,学习英语词汇既有效又简便的方法之一就是阅读。认知理论认为当学习者获得比较系统的语篇知识后,语言学习中的词汇和语法知识等零散构件就有了一个可以依附的“坐标系”,各成分不但有自己的顺序定位,同时也形成了相互间的组合和聚合关系,共同组成一个网络系统;信息不易遗忘又便于快速提取。阅读教学中要充分利用语篇提供的“上下文”价值进行适度的词汇处理,通过不断的循环和提升,促进词汇学习。Ellis提出了以频率为中心的二语习得理论,认为频率影响着语言从输入到吸收的转化,影响着语言加工的熟练程度和流利性,在语言习得理论中占有不可替代的重要地位。罗瑜对频率作用有比较客观、全面的评价:“尽管频率不能解释所有的语言现象,其效应却体现二语习得的各个方面,频率应是二语习得理论不可或缺的部分。”可见,以语篇为依托增加词汇复现频率可以加深学生对核心词汇的理解和记忆,提高词汇教学的有效性。
本文以人教版高中英语Book 2 Unit 2 The Olympic Games的词汇教学设计为例,以语篇为依托,设计层层深入的词汇练习,实现奥运核心话题词汇的循环和提升,希望这节课能为高中英语一线教师提供有益的课堂教学经验。
二、课例简介
(一)教学内容分析
本单元的中心话题是奥运会。Reading部分是一个采访,关于现代奥运和古代奥运的异同。文章按照五个问题展开,以事实性材料为主,适合设计主旨大意和事实细节类阅读活动。在层层深入的阅读活动后,让学生运用所学词汇介绍北京冬奥会。活动中,循環出现和使用表示举办时间、参赛者、比赛项目、场馆、主办城市、奥运精神等的话题词汇,实现在具体的语境中理解和运用词汇。
