JEFC Book 3 Unit 3《Make our world more beautiful》教学片段案例教学目的：“环境保护”已是近年来的一个热门话题，它与人们的日常生活密切相关，是学生比较熟悉的话题之一。谈论学生比较熟悉的环境问题，容易抓住学生的兴奋点，话题基于学生的生活世界，人人有话可说，积极踊跃参与，课堂气氛活跃。本教学片段将针对这一话题展开讨论。教师采用“任务型”教学方法，提出问题层层设疑，师生平等共同学习，使学生深刻地受到了一次环境保护的教育，从而明白了人与自然应和谐相处，才能真正享受到美好生活的道理。教学重点：本课是学习关于环境的课文。通过优美的环境图片和遭受严重破坏的环境图片对比呈现，使学生不由自主地向往美好的生活环境，痛恨种种破坏自然的行径，也促使学生反思自己过去的行为，激发学生的正义感和社会责任感, 从而锻炼学生的口头表达能力。老师采取层层深入提问和设计一些有计划的活动，拓宽学生知识面，并运用所学的知识开展积极的思维活动。教学手段：采取authorware多媒体课件进行教学教学步骤：（教师从报刊杂志或利用网络等多种途径搜集有关人为破坏环境的图片资料）T: Now boys and girls, I’d like to show you some pictures. Please watch them carefully, describe them and tell us how you feel.（教师利用多媒体手段呈现以下画面）1． 清晨的公园里鸟语花香，人们悠闲地锻炼健身、跑步等。2． 茂密的森林里，阳光普照，动物们在戏耍。 3． 大海边大树环绕，绿草铺地，海里游人戏水。4． 晴夜，星光灿烂，皎月似水,一对对情侣在树丛中依偎私语。（学生认真观看，发出阵阵赞叹声）T: They are beautiful pictures, right? Now who would like to say something about the pictures?（Task 1）S1: This is a park. In the morning, there are all kinds of beautiful flowers, birds are singing.

Maybe we can go there for a visit one day.S4: That’s a very nice evening. In the sky, there are many bright stars. The moon is round and it’s shining brightly.

You may ask yourselves or your partners.(学生开始阅读、思考与同桌交流)教学案例蕴含的理念：一、课程要面向社会生活实践《新英语课程标准》基本理念（六）中指出英语课程力求合理利用和积极开发课程资源，给学生提供贴近学生实际、贴近生活、贴近时代的内容健康和丰富的课程资源。即要把学生从课程领入社会生活的实践之中。一方面可以拓展课程时空，使学习不再仅指一堂课所学的内容，它打开了学生的视野，把多种有关知识浓缩在了一起；另一方面把生活世界提供给学生理解和体验，提高学生对生活的深刻理解和深入感悟，使他们不断领悟人生的意义，了解人不但活着，而且知道人应该怎样活着，使他们在与世界的沟通中感受生命的崇高，使精神世界日益丰富起来。如在本案例中，教师首先使用多媒体形象生动地呈现四幅图画，让学生直观地感受鸟语花香、椰风海韵等。接着反问“but I think the chance to see such a scene is getting less and less, do you agree with me?” 这时让学生展示搜集来的图片资料，谈感受，使学生真切地明白：人类随意乱扔垃圾，乱排污水，乱砍滥伐，使地球资源受到破坏，水土流失加剧，沙尘暴肆虐等。人们的正常生活已受到严重影响，人类本身受到了大自然的报复。两次正反画面的展示和对比，使学生触动极大，爱护环境，保护家园的强烈责任感油然而生，反省自身，使学生懂得：爱护环境，人人有责，保护环境，从我做起。二、让课堂教学充满创新活动《新英语课程标准》中指出基础教育阶段英语课程的任务之一为培养学生的观察、记忆、思维、想象能力和创新精神。开发学生的思维能力和培养学生的创新精神，是人的个性发展价值的需要。在本案例中，教师的几个问话，如“Then what should we do to help improve the environment?”, 学生的主动性即被调动起来，当然思考研讨氛围也随之而起，学生积极发言，群策群力。教师把书本知识与现实生活结合起来，加深了学生的感情认识，丰富了语言学习的内容。学生的创造潜能在这样的氛围中得到了发挥和展示。三、给每一个学生以平等民主是现代课程中的重要理念。民主最直接的体现是课程实施中学生能够平等地参与。没有主动参与，只有被动参与，就没有民主可言。相反，如果没有民主，学生的参与就不是主体参与，而是被动消极的参与。在课程进行中，教师应当放弃外在性权威，努力形成以知识、素养与人格魅力为内容，以与人为善、和蔼可亲为外部特征的内在性权威，以学生平等相待，这样每个学生都能主动参与教学，体现了师生间、生生间的平等关系。在本案例中，教师给学生足够的平台空间，自由谈论发言，并对各个学生的发言加以肯定，使学生在平等和谐的氛围中尽情畅谈心中的想法。
