探究式教学【教学设计】Unit 2 Healthy eating （人教版）.docx

Unit 2 Healthy eating 蚌埠二中 马爱军教学模式介绍探究式教学模式是指在教学过程中，要求学生在教师指导下，通过以“自主、探究、合作”为特征的学习方式对当前教学内容中的主要知识点进行自主学习、深入探究并进行小组合作交流，从而较好地达到课程标准中关于认知目标与情感目标要求的一种教学模式。其中认知目标涉及与学科相关知识、概念、原理与能力的掌握；情感目标则涉及思想感情与道德品质的培养。探究式课堂教学模式的教学环节：创设情境启发思考自主（或小组）探究协作交流总结提高设计思路说明1.总体思路以英语探究式教学为指导思想，将教学内容和学生实际及热点话题相结合，按照新课标对教学的要求来设计本节课的教学。教学中以智慧教学手段为辅助教学手段，以任务型教学法为主要教学方法进行教学。所设计的任务主要有三个：一是基本课文阅读任务运用有效阅读技巧，充分理解课文，输入信息、整合信息；二是语言交际任务运用所学语言进行现实交际，选择信息，输出信息；三是创造性任务创造一个健康食谱，这个任务可延续到课外。另外，通过课堂上的头脑风暴、个人阅读活动、猜图竞赛、双人活动和小组讨论等活动，激发学生学习兴趣和求知欲，开启学生思维之门，培养学生相互合作精神。让学生在真实的活动中，亲身体验、相互合作。所有活动的展开力求环环相扣，整节课生动流畅，从而实现本节课的各个教学目标。本节课所用到的教学方法有：1自主探究法：从探究中发现问题，分析问题，从而提高学生解决问题的能力。2合作学习法：让学生在讨论交流中取长补短，培养学生的合作竞争意识。3自主学习法：对于一些内容，同学们通过思考老师提出的问题、观看微课视频自主学习。使学生由“学会”变为“会学”，通过这些方法，孩子们提高了自主学习和独立思考的能力，学会了总结。【创设情境】为了与饮食这样的话题内容相匹配，我特意为课件选择了鲜艳精美的图片，使课堂气氛瞬间活跃；而头脑风暴和讨论活动可以使学生的思维活跃，激发学生学习欲望和对阅读内容的期待。【启发思考】 通过头脑风暴，通过和学生分享对食物的知识，鼓励学生对“healthy diet进行思考，激发学生兴趣，为阅读做好充分准备。教师可以通过各种方式启发学生不要拘泥现成答案，从多个角度思考问题，充分发挥思维的新颖性、创造性，只要合理、新鲜、有趣，或有其他任何独到见解，都给予鼓励。【自主或小组探究】这个环节是对整篇文章信息的归纳与梳理，进一步巩固学生对文章内容的把握，同时培养学生处理信息的能力，并为下一步讨论打下坚实的语言基础。（1）培养学生运用skimming, scanning阅读技巧的能力；（2）通过Discuss，Compare，Conlusion等激发学生深入理解课文的欲望，我们不应低估学生的能力。（3）通过Pre-reading，detailed questions，Careful Reading部分虽然也是对文章细节的把握，但着眼于整个篇章的阅读。【协作交流】 学生只有经过了认真的自主探究，积极思考后，才可能进入高质量的协作交流阶段。经过前几个环节，学生已经对文章有了深刻的理解，完成了信息的输入与理解。这个环节设计了好几个任务型活动，通过双人活动和小组活动，如：Who will win the competition at last? What do you think Wang Peng will provide to win his customers back? In groups discuss how to run the business. 培养学生的批判性思维能力和创造性思维能力。 （如果时间不足，此活动可以延伸到课外或者作为课外作业完成）【总结提高】 通过中介和复述，提升对全文信息和大意的理解。【课外作业】课外作业是课堂学习的深化、补充、和延伸。上述第一项作业完成了对课文内容的复习，让学生学反思自己的学习行为与学习效果，让其在写作过程中得到体现。第二项作业旨在督促学生课后再次阅读（或朗读）课文，通过再次阅读，近一步理解课文内容并试着“读而质疑”。教材分析本单元以“健康饮食”为中心话题，通过单元教学让学生了解各种食物对人体的作用，引导学生关注平衡膳食，促使学生养成健康饮食的习惯。针对现实中遇到的实际问题发表自己的看法。最后让学生运用所学知识，两人一组研究中餐，设计食谱。1. WARMING UP是本单元一个重要的组成部分。让学生看图讨论不同食物对人体的作用，了解饮食与人体健康的关系。通过几个设问激发学生思考自己的饮食习惯是否合理，运用已有的知识经验思考什么是Healthy Eating.2. PRE-READING 通过一个表格和一个排序题引导学生对比不同食物中哪些食物富含脂肪、纤维素、维生素和糖份。可添加讨论如何在烹饪中保持食物营养，从而有利于健康。3. READING 讲述王鹏和咏慧开饭店的不同风格和顾客对不同食品的反应，反映了现代人对饮食的关注和对时尚的追求。但王鹏和咏慧都没有提供平衡的膳食，经过一段时间的磨合，他们决定合作，提供既有能量又有纤维的食品。戏剧性的结尾增添了故事的趣味性。通过阅读丰富学生的饮食文化，教会他们如何改善饮食习惯；在现实生活中碰到麻烦时，如何正确处理矛盾，解决问题。4. COMPREHENING 利用判断和回答问题的形式考查学生对课文细节的理解，对比两家饭店所提供膳食的优缺点。5. LEARNING ABOUT LANGUAGE 是继Comprehending之后的又一指导性练习。注重考查词性的变化，课文中重点词汇在语篇中的熟练运用及情态动词的不同功能，并设计连线和情景对话两个题型予以巩固。6. USING LANGUAGE 体现了学以致用的目的，从Listening, Reading, Speaking, Writing 四方面训练学生，完成语言的输入性学习和输出性训练的过程，结合生活实际，让学生两人一组研究中餐设计食谱。教学目标【知识与能力目标】(1) Guide Ss to learn some new words and expression.(2) Enable the students to talk about Chinese festivals and customs in English and get to know some information about foreign festivals.【过程与方法目标】本课围绕饮食的话题展开教学活动。它适用于培养学生获取信息、整合信息以及解决问题的能力，着重培养阅读能力，同时培养学生口头表达能力、创造性思维能力, 培养学生过一种健康的生活方式。【情感态度价值观目标】(1) Enable the students to learn how to live a healthy life. .(2) Develop Ss sense of cooperative learning教学重难点(1) How to talk about the healthy diet.
