语境中的词汇教学,-湖北省教学研究室 罗之慧,要点,词汇教学现状 词汇教学对策 词汇教学课例 结语,词汇教学现状,1.为避免破坏阅读教学的整体性，课前讲授生词， 让学生背生词表。 2.为凸显词汇教学的重要性而过多讲解词汇。 3.为保障词汇教学的“全面性”而对不同层次的 词汇平均用力。 4.词汇教学方式单一。,解决策略(一）,词汇的分层 第一层：课标规定需要掌握的词汇，即教材生词表中不带 部分。 第二层：单元重点词汇与短语，即教材生词表中黑体部分。 第三层：话题拓展词汇，属于认读词，大部分只需听懂、会读。,解决策略二,词汇教学的多元化 词汇教学方式单一会让学生觉得枯燥，易产生厌烦情绪，影响词汇学习效率。词汇教学的多元化是解决词汇教学问题关键。 1.词汇教学生活化 5.词汇学习策略培养 2.词汇教学任务化 构词法、猜词法、 3.多种方式交替使用 查阅词典法 4.词汇教学语境化 词汇复现法,词汇教学语境化,直接通过汉语释义往往会使英语词汇与语义 运用割裂，不利于语言的有效学习。在词汇 教学中要尽量给学生创设真实的语境，让学 生在语境中体会词汇的运用，再学会创造性 地运用。,解决策略三,将目标词汇的学习与阅读材料的理解有机地 结合，关注读前、读中、 读后阶段的词汇 处理为设计思路，通过paraphrase、语 义归纳、构词法、猜词法、翻译法、跟读、 句式转换等多种策略和方式展开词汇教学 使词汇学习和运用自然地渗透到文本地解读 中，加深学生对词汇的理解与运用。,具体步骤如下： 1.读前感知词汇（激活学生已有的知识） 2.读中理解词汇（结合课文内容） 3.读后运用（结合课文话题）,教学实例,教材分析： 人教版教材选修7 Unit 2的阅读材料是科幻 小说。故事借助丰富的描述心理状态的形容 词，讲述了女主人与她的家务机器人之间发 一系列的故事，生动地刻画了机器人富于人 性化的细节。文章篇幅长，词汇量大。对大 多数学生而言有相当的难度。,语言知识目标分析： 一级目标词汇： alarmed/alarming,absurd,awful,dissatisfied dissatisfying/dissatisfation (本课生词） embarrassed/embarrassing/disturbed/ （已学关键词汇） 二级目标词汇：household/accompany/elegant/offer sympathy/test out/envy/wear/make up（有助于文章理解、课标规定掌握的词汇）,教学片段分析,一.读前预热，浅尝感知 根据布鲁姆教学目标分类法，识记层次是对 具体或抽象知识的辨认。读前环节的预热活 动旨在激活学生已有的背景知识，并让学生 感知，记忆相关的新词汇。这是本课的初级 词汇教学目标。,教学片段1 (1)导入 教师根据课前的MV内容提问。 T: What can the robot do in the MV?
