Unit2 Topic3 Section A教学教学设计设计 教材：科普2011课标版九年级上册 课题：Unit2 Topic3 Section A 【教材分析】本单元以Saving the Earth为主题，共包括三个话题。通过Kangkang, Jane, Michael等人谈论环境污染带来的问题及怎么保护环境等，完成本单元三个话题 的语音、词汇、语法和功能项目的学习。本节课是第二单元的第三话题的第一课 时，本课的主要活动是1a, 1b，1c,3a和3b。将通过展示本节课的学习目标让学生了解学习内容，做到有计划 有目的地开展教学，并通过出示学生平时回收生活废品的实际生活体验引导学 生会对日常生活废品进行分类，树立环保意识，之后通过Journalist对Jane的采访 ，询问有关Jane在环保组织的活动，学习对如何在家和在校对环境保护这一话题 提出建议，最后，让学生根据本节课或已有的知识进行讨论并自由谈论如何成为 一个环保小卫士，让保护环境，从身边小事做起这一理念深入到生活的每一个角 落，落实到具体行动中来。1b是个难度系数比较高的听力任务，它不是单纯的考 查听写，而是要求学生在听懂内容的基础上，对材料进行归纳以后再填空。而1c 是阅读对话根据对话内容进行填空和新对话的设计，旨在向学生传播环保理念。 3a和3b是在考查学生的垃圾分类意识之后，再通过听对话来进行验证。因此，本 课设计的活动本人从易到难，层层相扣，这样不仅能提高学生的兴趣，还能让学 生很好地完成本课的学习任务。 【学情分析】对于九年级的学生来说，能自觉进行新课预习，由于本课新单词 较少，而且新课前已将新单词教授给学生，学生只要能在具体语境语篇中理解， 学起来会比较轻松。环境保护与生活息息相关，信息量较多，因此教师要对教学 任务合理分配，能面向全体学生，让学生在已有知识的基础上去进行表达，把问 答、学生的合作讨论和小组活动贯穿整个教学过程中，贴近学生生活图片和具体 实物废品可以吸引学生学习的兴趣，激发了学生学习的主动性。 【教学目标】 1知识与技能： （1）学习新单词:protection, organization, recycle, plastic,can,battery； （2）学习谈论:what we can do at home and at school to protect the environment (3)学会分类:different kinds of garbage. (4)学会谈论:”How to be a greener person?” 2过程与方法： （1）师生互动，小组合作讨论； （2）图示法展示。 3情感态度价值观： 通过对Section A的学习，要求学生能根据1a和3a的内容自由谈论怎样成为一个环保使者，帮助 他们树立环保意识;能对生活废品进行分类，乐于做环保使者，增强社会责任感和 忧患意识。 【教学重点】 (1) 学习本课新单词并能根据Jane在环保组织的工作谈论What can we do at home to protect the environment. (2) 能根据”3R”进行垃圾分类. 【教学难点】 要求学生在学习本课的基础上进行自由谈论话题：How to be a greener person. 【教学时间】38分钟 【教具】多媒体教学课件 【教学过程】 Step 1 Greetings and lead-in Greet students as usual and show the teaching objectives.
