教学设计理念
主题语境引领下的词汇、语法教学,英语学习活动观
1. 新课标要求“根据主题内容,构建不同的词汇语义网,积累词块、扩大词汇量”。本节课在设计时,将主题意义引领下的英语学习活动观与词汇、语法教学相融合,通过创设与野生动物保护相关的真实、有趣的语境,引导学生在句子或语篇中通过阅读、观察、分析、理解、归纳去探索并理解运用目标词汇与目标语法结构的形式、用法和意义。
2. 基于新课标下的核心素养目标,本节课继续按照“学习理解—应用实践—迁移创新”的思路进行设计。
3. 强调学生在语言学习中的主体地位,引导学生积极参与符合其认知的、层层递进、相互关联、有真实情境的课堂活动,践行英语学习活动观,培养学生的跨文化交流意识、批判性思维以及自主学习能力和合作意识,通过练习和作业强调词汇、语法的语用功能。
教材分析
【What】本文是一篇旅行日志(Travel Journal),以第一人称视角记录了作者在西藏羌塘国家级自然保护区的所见、所闻、所感。文章按照“所见——所闻——所思”的逻辑顺序展开:第一、二段描写了作者在高原上观察藏羚羊的场景;第三至六段通过向导扎西的介绍,讲述了藏羚羊曾经面临的生存危机(20世纪80、90年代数量锐减超过50%、栖息地缩小)以及中国政府采取的保护措施(国家保护、志愿者日夜守护、修建桥梁和通道等);第七段表达了作者的思考与感悟——只有学会与自然和谐相处,人类才能停止对野生动物和地球的威胁。
【Why】学生通过阅读语篇,了解藏羚羊这一濒危物种的保护故事,认识到野生动物保护的重要性和紧迫性,探究人类活动对野生动物生存的影响,学习人与自然和谐共处的理念,增强保护野生动物的意识和责任感。
【How】 作者按照“所见(what I see)—所闻(what I hear)—所思(what I think)”的脉络组织语篇,采用旅行日志的文体形式,融合了事实陈述与个人感悟。文中运用了丰富的描写性语言(如graceful animals, snow-covered mountains)和说明性语言(如population dropped by more than 50 percent, placed it under national protection),同时使用了直接引语(如“We’re not trying to save the animals,” he says. “Actually, we’re trying to save ourselves.”)来增强语篇的真实性和感染力。文本中涉及野生动物保护话题的核心词块有:observe Tibetan antelopes, illegally hunted, under national protection, watch over, habitat, endangered species, exist in harmony with nature等。
学情分析
1. What I know
词汇方面:学生在之前的学习中已经掌握了一些与动物和自然相关的基础词汇,如“animal”“forest”“protect”等。这些词汇能够帮助他们初步理解课文的主题。他们也熟悉一些描述动作和状态的动词,如“live”“hunt”“save”等,这对于理解文中提到的保护措施很有帮助。
语法方面:学生已经学习了基本的句子结构,如主谓宾、主系表等,能够理解简单的陈述句、疑问句和祈使句。对于阅读课文中的句子理解有一定的基础。他们还掌握了一些从句的知识,如宾语从句、定语从句等,这有助于他们分析复杂句子的结构。
背景知识方面:学生在日常生活中对野生动物有一定的了解。他们知道一些濒危动物(如大熊猫、藏羚羊等),也对环境保护有一定的认识。这些背景知识能够让他们与课文内容产生共鸣,更好地理解作者的观点。
2. What I want to know
学生可能想要了解更多关于藏羚羊的具体信息,如它们的生活习性、栖息地特点等。他们可能对不同国家和地区的野生动物保护政策和措施感兴趣,希望进行比较学习。学生可能希望学习更多与野生动物保护相关的专业词汇和表达,以丰富自己的语言储备。他们可能想了解文中出现的一些复杂句子结构的用法,以及如何在写作和口语中运用这些结构来准确表达观点。
3. What I learned
主题内容方面:通过阅读课文,学生将了解到藏羚羊从濒危到种群恢复的感人故事,认识到人类活动对野生动物的影响,以及中国政府为保护野生动物所做的努力。他们会理解人与自然和谐共生的重要性。
语言知识方面:学生将学习新的词汇,如antelope, reserve, habitat, illegally, harmony等与野生动物保护相关的词汇。他们会接触到一些新的句子结构和语法现象,如现在分词作状语、定语从句等。同时,也能学会如何运用这些语言知识来描述和讨论野生动物保护相关的话题,提高自己的阅读、写作和口语能力。
教学目标
语言能力
掌握野生动物保护话题词句(如antelope, reserve, illegally hunt, under national protection, exist in harmony with nature等),能用于口头和书面表达;能提取文章关键信息,处理细节、主旨和推理类阅读任务。
学习能力
运用预测、略读、扫读、猜词等策略提升自主阅读效率;通过小组讨论、角色扮演等合作活动,学会倾听、分享与互评,在协作中调整学习方法,提高团队与人际交往能力。
文化意识
了解中国在野生动物保护方面的成就(如藏羚羊保护级别降级),认识世界各国保护野生动物的共同责任,增强生态文明意识;理解保护野生动物是全球共识,关乎人类社会可持续发展,形成尊重自然、保护环境的价值观。
思维品质
梳理文章结构,分析段落逻辑(按照“所见—所闻—所思”的旅行日志线索),能用思维导图呈现;对文中观点进行批判性评价(如“We’re trying to save ourselves”的深层含义),鼓励提出个人见解,培养独立思考、批判性思维和问题解决能力。
教学重难点
教学重点
语言维度:学生需掌握野生动物保护相关词汇、短语、句式及复杂句子结构,以理解和表达相关内容。
阅读与文化维度:掌握阅读技巧获取信息并分析文本结构(旅行日志的文体特点),同时理解野生动物保护的重要性和中国在保护藏羚羊方面取得的成就,提升文化认知。
教学难点
语言深度运用:精准辨析易混词汇(如reserve/reservation, exist/insist等),剖析长难句(如“Only when we learn to exist in harmony with nature can we stop being a threat to wildlife and to our planet!”的倒装结构)并处理文化内涵词汇的理解与翻译。
思维提升:批判性思考课文观点(如“save animals = save ourselves”的哲学内涵),实现从故事理解到生态价值观内化的跨越,构建人与自然和谐共生的理念。

Reading and Thinking
教学反思
优点:
教学设计紧密结合新课标的相关要求,注重学生的实际应用能力和思维能力的培养。通过多样化的教学活动(如视频导入、预测、略读、精读、讨论、海报制作等),激发学生的学习兴趣并提高学生的参与度。教学设计按照“学习理解——应用实践——迁移创新”的思路层层递进,符合学生的认知规律。思维导图的运用帮助学生系统化地掌握文章结构。分层作业设计兼顾了不同水平学生的需求。
缺点:
在某些活动的设计中,可能未能充分考虑所有学生的个体差异,可能会导致部分学生跟不上教学进度。阅读任务较多,时间分配上可能需要进一步优化。课堂互动环节中,部分性格内向的学生可能参与度不够。
改进:
今后应更加关注学生的个体差异,提供个性化指导和支持,尽量使所有学生都能参与到课堂中来。可以适当精简部分阅读任务,给学生更多思考和表达的时间。在小组活动中,可以采用角色分配的方式,确保每位学生都有参与的机会。课后可提供更多拓展阅读材料,满足不同层次学生的学习需求,提升学生英语学习的信心和兴趣。
