二、学习分析苏霍姆林斯基认为：“教给学生方法比教给学生知识更重要。
”建构主义是近年来介绍到我国的一种新兴教育理论，它认为知识不是通过教师传授得到，而是学习者在一定的情境即社会文化背景下，借助学习过程中其他人（包括教师和学习伙伴）的帮助，利用必要的学习资料，通过意义建构的方式获得的。
基于这样的认识，结合本课内容和初三年级学生的特点及学习经历，在教学中我侧重指导学生采用以下三种学习方法：1．合作学习法。

Basketball was invented by a Canadian doctor named James Naismith, who was born in 1861. When he was at college, his class was once asked to invented a new game that could be played indoors during the long winters. Dr.Naismith created a game to be played on a hard wooden floor,so the safety of the players was important. Knocking into players and falling down would be dangerous.

Unit 9 When was it invented？（Section A）一．语法：被动语态1.被动语态的时态: 被动语态的时态通过be的变化来体现，它必须与主语的人称、数一致。
以下是几种常用的被动语态:(1)一般现在时的被动语态: am / is / are + 动词的过去分词。
Eg：This book in two languages.这本书是用两种语言写的.(2)现在进行时的被动语态: am / is /are + being + 动词的过去分词。
Eg: A school is by the workers now.工人们正在建一所学校.(3) 一般将来时的被动语态: will / be going to + be + 动词的过去分词.Eg: The project will next month.这项工程下个月就完工.(4) 现在完成时的被动语态: have / has + been + 动词的过去分词.Eg: My homework .我的作业以完成了.(5) 一般过去时的被动语态: was / were + 动词的过去分词.Eg: The classroom three days ago. 教室是三天前被打扫的.(6) 含有情态动词的被动语态: 情态动词+be +动词的过去分词.The classroom every day.教室应该每天都被打扫.2.被动语态的否定句和疑问句:（1）否定句的构成：必须在第一个助动词后加not。
Eg：His homework finished. 他的作业还没有完成。
（2）疑问句的构成：将第一个助动词置于主语之前。
Eg：When the bridge ？这座桥是何时建的？3、主动语态变被动语态的方法:（1）把主动语态变的宾语作为被动语态的主语（2）主动语态的谓语改成be + 过去分词的形式，作为被动语态的谓语，be随着主语以及时态的变化而变化。
（3）主动语态的主语变为by的宾语，有时可以省略。

九年级英语 Unit 9 When was it invented教案 人教新目标版 教案
Unit 9 When was it invented ?【教材版本】人民教育出版社九年级英语【学习内容】Grammar Focus, 3a, 3b and 4 of Unit 9 When was it invented ?【学情分析】本节课是第九单元的第二课时, 学习任务是完成课文Grammar Focus, 3a, 3b and 4 部分的学习。
本单元要求学会谈论重要发明的历史及用途，然后针对各项发明的用处及特点，发表自己的看法，并说明理由。
话题一直是围绕着历史上和日常生活中的重要发明，通过使用“Passive Voice”形式的句型，循序渐进地展开讨论。
课本设计的活动情景能够自然地引发学生的好奇心，大家积极地投入到话题讨论中，寓教于乐，容易引起学生的兴趣；同时，它也有利于开阔学生的思路，培养创造精神，展开丰富的想象力，人人都能成为“小发明家”。
学生在第一课时学习了本单元的Section A 中的1a至2c部分，基本能听懂、会说本单元要求掌握的部分重要词汇；在图片，相关信息等提示的帮助下，能较好地运用重要句型和掌握主动语态和被动语态及相互转换。
但是本班的学生两极分化比较严重，有一部分学生基础知识不牢固，前面提到的学过的单词和句型就忘得差不多了，特别是对于课文中的语法—主动语态和被动语态，被动语态的一般现在时和一般过去时混为一谈。
所以教师在课堂教学中应面向整体，及时复习相关的知识，包括重要词汇和句型，前后知识的衔接。
同时在设计上要注意活动的多样性，激发他们的兴趣，让每一位学生能得到不同程度的收获。
【单元整体目标】重点词汇：salty, sweet, sour, crispy, pleasant, potato chips, slipper, leaf, fire, scoop, light bulb, microwave oven, abacus, camera, beverage, be invented by, be used for, by mistake, by accident重点句型：When was the telephone invented? I think it was invented in 1876.技能目标：能够谈论发明的历史和用途。
