Book8 Unit 3 Inventors and inventions
教学设计
教材分析
本单元的中心话题是“发明家与发明”，具体涉及“发明与发现的区别”、“发明产生的过程”和“申请发明专利的条件”。语言技能和语言知识都是围绕“发明”这一中心话题设计的。只要人类在地球上生存起，发明就是人类生活的一部分。每一项发明都是每一个人在解决问题和应某种特别的需求，经过不断的科学实验的结果。因此发明和发明家不是新东西，只要大家勤于思考、发挥想象力和创造力去解决问题，就可能有所发明。
学情分析
1）经历了高一阶段后，学生们已经熟悉了高中生活，有些同学认为高三毕业还早，所以有些学生自主、自觉学习的能力就下降，缺乏刻苦钻研的精神，这也无形中会影响到其他同学的学习。这就需要老师不断的督促和检查；
2）还有些认真刻苦的学生欠缺必要的学习方法；
3）学生整体学业水平偏低，且有很大的差异，这种差异还将会随着学习难度的加大、学习时间的延续而扩大。
4）基础知识不够扎实，灵活运用语言的技能相对薄弱。
5）运用能力不够强实。学生的阅读能力、理解能力、分析能力、判断能力、应变能力等均不能较好地适应考查要求。语言学习的关键在于语言知识的积累，只有通过学习者亲身的体验和摸索，才能学会并掌握语言知识，从而达到在交际中灵活使用语言的目的。

本节课基本上贯彻了当初的设计意图，并且按时完成了各个环节的任务。通过这次授课我深刻体会到以下几点：
继续发扬点：
1. 将课堂交给学生能够充分发挥学生的主动性和积极性。
2. 设计相关的练习题能够让学生带着问题阅读，能够培养学生独立思考问题的嫩听力，同时能够提高学生的阅读能力。
3. 通过小组竞赛的方式能够最大程度地发挥学生的积极性，甚至有些平时上课不积极的学生也表现出了极大的热情。
需要改进点：
1. 因为学生的基础不一样，课堂上学生的接受能力也不一样，因此要适当的延长任务时间，争取让所有学生都能跟上课堂。
2. 阅读时学生的阅读时间应适当加长，一边学生能更透彻地理解课文。
3. 给学生提供的的参与机会。比如讨论环节，可以让不同层次的学生展示自己的作品。
