反思：
【课堂评价】
本节教学较为成功的做法：
1、导入部分由题目中的单词导
( http: / / www.21cnjy.com )入既拓展了相关知识又要学习的主要线索，引出发明家Edison及inventor
，由Edison
invented
the
light
bulb.到被动语态The
light
bulb
was
invented
by
Edison.
进而进行了相应的句型转换。学生自然而然地调动学生的积极性，很轻松地归纳出了即将学到的主要内容。为后面的课堂话题真正展开作好铺垫。如果这些内容掌握了就等于会应用了。
2、学生在本堂课中得到了较为充分的口头
( http: / / www.21cnjy.com )训练，而且面比较广，这一点尤为重要。一些原来在课堂上很难开口读英语的学生，本堂课上有极大的进步，敢开口说了。
3、能充分利用多媒体容量大，直观性强的
( http: / / www.21cnjy.com )特点。利用科学、历史等学科中对发明物和发明家的理解（如：爱迪生发明电灯泡，卡尔发明汽车，贝尔发明电话等信息）学生感兴趣的来调动学生思考的积极性。拓展中国的四大发明，既使学生增长了见识又巩固了所学内容，操练的时候，学生学的特别的认真。
4、俗话说“兴趣是最好的老师吗？”我就是
( http: / / www.21cnjy.com )在这一堂课中给学生不同的学习方法,也可以说是他们比较感兴趣的，抓住他们的注意力。最大限度的发挥他们本身的潜力，由他们原先的被动学习变为现在的主动的学习。正因为他们对本节课充满着兴趣,所以就有很大的乐趣去学习,从而就他们积极的、认真的读课文，听我解讲课文中的重点知识。也在积极的动脑回答、思考我所给他们出的问题，从而很顺利地完成了本堂课的教学任务的。
5、有效的媒体手段有助于课堂容量、密度和速度
( http: / / www.21cnjy.com )的提高。尤其是在英语课堂上适当地使用多媒体手段，不但可以活跃课堂，更能提高学生的参与面，短、频、快的大容量课堂节奏能有效的吸引并集中学生的学习注意，从而最终提高学习的听课效益；其次，课堂效益意识还体现在教学的设计中要充分为学而教，以学生如何有效获取知识，提高能力的标准来设计教学。课堂设计要有助于学生在课堂上积极参与，有助于他们有效内化知识与信息，复习过程中要重视学习方法的指导，在教学中恰当地渗透中考的信息，拓宽教学内容。

【教材中的地位和作用】
本课是人教版九年级第六单元“When
was
( http: / / www.21cnjy.com )
it
invented ”的第一课时，本单元涉及内容是本书当中比较重要的一部分。被动语态结构及运用是教学中一个难点和重点，也是学生比较不容易理解的部分，因为它是建立在各种时态之上的。是中考的一个重点，也是难点，根据英语课程标准要求“能够灵活运用英语去做事情”，学生必须通过学习能够正确地运用本单元所学的被动语态，去描述物品的被创造、被发明的历史过程，从而达到学以致用的目的。
另外通过对我们熟悉经常使用的发明物的历史来开阔眼界，丰富学生的阅历，使学生养成勤于思考，善于总结的好习惯。
【教材内容分析】
本节教学内容为人教版英语九年
( http: / / www.21cnjy.com )级Unit
6，话题为讨论介绍物品的发明历史和用途，主要是让学生能够正确熟练地听懂并运用被动语态来介绍物品的发明过程和历史，通过本节课的学习，学生需要熟练掌握一般过去时态的被动语态，在学习中，懂得人类的科学发明创造了丰富的物质文明，激发创造发明的能力和愿望。
【教学建议及教法指导】
新制定的《英语课程标准》把“培养
( http: / / www.21cnjy.com )学生学习英语的兴趣，树立自信心，培养良好学习习惯和形成有效策略，发展自主学习和合作精神”放在了首位。依据课改的精神，我从以下几个方面对学生进行学法指导。
1、学习方法的指导培养学生观察力，想象力，记忆力以及思维能力。用生动的课件调动学生的感官进行听说读写的训练。
2、学习积极性的调动我在教学过程中创造一种开放的，和谐的，积极互动的语言氛围，把课堂变成有声有色的舞台，让学生在乐中学。
3、学习能力的培养通过连贯的听说读写，游戏等，培养学生的交际能力，发展他们的思维能力。
4、学习策略的指导本节课将在课堂活动中把学
( http: / / www.21cnjy.com )生分成四人小组的学习小组，让他们围绕着课堂任务分工合作，在活动中相互探讨、相互交流、相互合作，从而获得知识、技能和情感体验，发展他们的能力。创建开放式，探究式的课堂，有意识渗透学习策略的训练。我让学生观察课件画面，回答问题，让学生学会使用认知策略；让学生表演对话，实现交际策略；引导学生交际，主动练习和实践，是调控策略的体现。充分利用多媒体，录音等是资源策略。
【教学效果预测】
1、
能够掌握被动语态，并运用到一定的语言环境。
2、通过多媒体和任务的完成学生会突破难点，产生一定创造精神。
3、能完成教学目标，调动学生学习热情。课后反思
Unit

When

it
invented
承第五单元一般现在时的被动语态，虽然是一种新的语法，学生们接受起来还可以，现反思如下：
本堂课的收获和优点：
1、导入部分由题目中的单词导入既拓展了
( http: / / www.21cnjy.com )相关知识又要学习的主要线索，引出发明家Edison及inventor
，由Edison
invented
the
light
bulb.到被动语态The
light
bulb
was
invented
by
Edison.
进而进行了相应的句型转换。学生自然而然地调动学生的积极性，很轻松地归纳出了即将学到的主要内容。为后面的课堂话题真正展开作好铺垫。如果这些内容掌握了就等于会应用了。
2、学生在本堂课中得到了
( http: / / www.21cnjy.com )较为充分的口头训练，而且面比较广，这一点尤为重要。一些原来在课堂上很难开口读英语的学生，本堂课上有极大的进步，敢开口说了。
3、能充分利用多媒体容量大，直观性
( http: / / www.21cnjy.com )强的特点。利用科学、历史等学科中对发明物和发明家的理解（如：爱迪生发明电灯泡，卡尔发明汽车，贝尔发明电话等信息）学生感兴趣的来调动学生思考的积极性。拓展中国的四大发明，既使学生增长了见识又巩固了所学内容，操练的时候，学生学的特别的认真。
4、俗话说“兴趣是最好的
( http: / / www.21cnjy.com )老师吗？”我就是在这一堂课中给学生不同的学习方法,也可以说是他们比较感兴趣的，抓住他们的注意力。最大限度的发挥他们本身的潜力，由他们原先的被动学习变为现在的主动的学习。正因为他们对本节课充满着兴趣,所以就有很大的乐趣去学习,从而就他们积极的、认真的读课文，听我解讲课文中的重点知识。也在积极的动脑回答、思考我所给他们出的问题，从而很顺利地完成了本堂课的教学任务的。
5、有效的媒体手段有助于课堂容量、
( http: / / www.21cnjy.com )密度和速度的提高。尤其是在英语课堂上适当地使用多媒体手段，不但可以活跃课堂，更能提高学生的参与面，短、频、快的大容量课堂节奏能有效的吸引并集中学生的学习注意，从而最终提高学习的听课效益；其次，课堂效益意识还体现在教学的设计中要充分为学而教，以学生如何有效获取知识，提高能力的标准来设计教学。课堂设计要有助于学生在课堂上积极参与，有助于他们有效内化知识与信息，复习过程中要重视学习方法的指导，在教学中恰当地渗透中考的信息，拓宽教学内容。
本堂课的不足之处：
1、本节英语课上我的讲解基本上还拘泥于教材的信息，而开放型的、能激发学生想象力与创造力和发散学生思维的课堂比例还较小。
2、课堂节奏相对较快，导入设计虽然比较好，但花的时间太长，以致在进行最后输出对话练习时，学生开放性的口头表达时间不够。
针对以上不足之处，我觉得今后在教学中应从以下几方面来提高：
首先，我们备课不仅仅要备教材，还
( http: / / www.21cnjy.com )要备学生。要根据学生英语基础的实际情况，设计一些开放性的资料来提高课堂教学质量。当然这些我们自己设计的教学素材不能脱离教材本身。
其次，英语课堂上我们应及时有效获取
( http: / / www.21cnjy.com )学情反馈，有效地进行课前回顾，课堂小结等环节的落实。为有效地提高英语课堂教学效益，我们还可以制定科学的、操作性强的、激励性的英语学习效果评价制度，以便在课堂教学过程中做出针对性的调整。
在今后的教学中，我要不断的
( http: / / www.21cnjy.com )更改教学方式，要从根本培养起学生学习的兴趣。只有兴趣才是最好的老师。好的先生不是教书，不是教学生，而是教学生学。我要积极进取，不断的提高自身素质，多听有经验老师的课，取其精华，并将其运用到自己的教学当中，不断反思自己教学中的不足，更新观念，愿与新课程共同成长。(共39张PPT)
