学情分析 对于九年级的学生来说，大部分学生已经有了一定的学习基础。他们有较明确的学习动机和态度。本单元以发明为载体，通过各种发明和发明家激励学生求知的欲望。对刺激记忆手段多的知识记忆深刻，遵从记忆规律。同时针对不同层次的学生设置不同的人物和不同的评价标准。大多数初中生主要通过他人评价初步形成对自己的评价，所以很在乎他人的评价。同时自我意识不断增强。因此在本课教学过程中，以任务型教学为主，通过任务和不同的评价方式，提高学生参与意识。

本节课从总体来看，我认为基本上完成了课前设置的教学目标，学生参与的积极性较高。
但是，上完这节课，听完老师的评价，加上我自己的感受，我认为还有很多不足之处。
课堂用语还不够简练。这好像是年轻教师的一个通病，口语化的东西太多。我是属于一紧张就会花朵的人，因此有的时候指令语不简练，以后要注意改正这一点。
本节课的句子较难，可以再多做几个示范，多给学生充分的时间去练习。
更进一步提高课堂效率，尽量做到“教的有效，学得愉快”。

本单元主要学习谈论重要发明的历史及用途，并能针对各项发明的用处及特点发表自己的看法，并说明理由。话题中心围绕着历史上和日常生活中的重要发明，通过使用“PassiveVoice”（被动语态）形式的句型，循序渐进地展开讨论。通过活动情景设置来自然地引发学生的好奇心，使学生积极地投入到话题讨论中，寓教于乐；同时，它也有利于开阔学生的思路，培养创造精神，激励他们展开丰富的想象翅膀，人人都能成为“小发明家”。

课标分析
2013年，国家教育部颁发了《普通初中英语标准》，俗称“新课标”。它是我们初中英语课程的纲领性指导文件。但是不管新课程中如何变化，英语中很多琐碎的只是仍然需要反复强调，反复操练，反复强调。本单元以发明为题材，听、说、读、写活动围绕着这一主题展开，同时学习了过去时态的被动语态，是本学期的一个难点。首先通过日常生活中一些重要发明的时间以及发明人导入，同时呈现了本单元的新目标语言学习：was/were invented，it’s used for...然后通过复习茶叶的发明故事，进一步激发学生的学习兴趣。然后学生自己总结本单元的语法项目，使他们对过去时态的被动语态有更一层的理解，掌握更牢固。学生又学习了贝尔发明电话的过程，使教学层层深入，同时让他们明白，nothing is difficult for a man who will try.最后，学生自己完成一篇关于发明的短文写作，从而达成了本单元的学习目标。
本节课的学习内容与学生的生活息息相关，因此从一开始学生就保持了浓厚的兴趣。通过一系列生活发明的导入，学生能将上节课学过的一般过去时的被动语态朗朗上口，熟练掌握。另外，通过多媒体课件的运用，对于多种情景的直观展示，更激发了学生的学习积极性。本节课，绝大部分学生都积极参与到课堂中来，包括一些英语基础不是很好的学生都敢于拒收展示自己的句子，这是一个很大的进步，通过语言的输入到输出，最后的写作部分，大多数同学都能较好的完成，比较完整的完成了本节课的学习任务。
