(1观察图解,色盲基因在性别间是如何传递的呢?(女--女、女--男、男--女)(2)为什么不能由男性传给男性?(色盲基因是在X染色体上,因此色盲基因是随X染色体的传递而传递。)(3)男性的色盲基因怎样才能传给男性呢?(通过女儿,传给外孙即交叉遗传)(4)从图解看色盲在男女中的发病情况怎样?(男性多于女性)(5)从社会调查也是这样,你是否能从基因和染色体的角度加以解释?(提示:女性染色体的构成,结合基因位置及显隐性进行分析)归纳特点:归纳出色盲基因遗传的特点并扩展到X染色体隐性遗传的特点上。色盲基因遗传(X隐性遗传)的特点:(1)男患者多于女患者(2)交叉遗传(3)女病儿子必病,男正女儿必正等。问题探讨:利用“遗传图解”结合“问题链”继续探讨,拓展到抗维生素D即X 染色体显性遗传的特点。(6)色盲基因在X染色体上属隐性基因,子代表现男多于女,对应的正常色觉基因则属于X显性基因,子代表现应如何?(女多于男)
回归生活:近几年,我国市场上猪肉价格在不断地波动。请智囊团商议:我们集团如何才能避免重蹈“张老汉”的覆辙?学生活动:思考、发言、群策群力。教师鼓励学生从多角度分析,找出解决问题的不同方法。教师点拨:在猪肉价格波动较大时,我们除了调节生产规模,还可以采用引进新品种、加强科学管理等手段来提高劳动生产率,从而在价格竞争中更具优势。同时,我们要在激烈的市场竞争中站稳脚跟,还必须以市场为导向,生产适销对路的高质量产品,做到“人无我有,人有我优,人优我转”。教师引导学生分析:价格变动对生产规模的调节、对劳动生产率的提高及促使企业生产适销对路的高质量产品,就是在价格、供求关系及市场竞争的刺激下,价值规律发挥“棒子”(调节资源配置)、“鞭子”(鞭策个别劳动生产率的提高)及“筛子”(优胜劣汰)作用的结果,从而将本节课的内容与第一框题有机联系在一起,帮助学生从不同角度更深刻的理解价值规律的作用。
2、传授新知与学生展示(35分钟) 先由老师点出本课的知识点,它包括:(1)经济全球化深入发展:结合课本91-93页理解经济全球化的含义;经济全球化的表现:生产全球化,贸易全球化,资本全球化;跨国公司是实现经济全球化的载体。(跨国公司的含义、目的、作用分别是什么)(2)经济全球化的影响: 经济全球化的实质:以发达资本主义国家为主导的经济全球化;消极影响积极影响;如何应对经济全球化。讲完了知识点,接着回归图片和书本的材料,给学生留下三个问题进行小组讨论:A :谈谈你感受到的经济全球化B :怎样理解经济全球化是一把“双刃剑”C:假如你是一位企业经营者,面对经济全球化趋势,你会怎么做?先完成讨论的小组可举手示意老师给予检查,老师根据需要抽查同学到讲台进行展示讨论的结果,并对表现突出的小组进行当堂奖励。
在学生明确了税收的含义之后,我将分别对税收的三个基本特征进行解析。在讲解了之后,并分别用实例对其进行说明,加深学生对知识点的印象。最重要的是,总结出关键的字眼,使得学生能够清晰的区分出税收的三个基本特征。将强制性概括为依法征税、依法纳税;无偿性概括为不具有偿还性和返还型;固定性概括为规定应不应纳税、纳什么税、纳多少税。并跟学生指出,强制性是基本前提,无偿性是核心。由此根据书上的内容,推导出税收的三个基本特征相互之间的关系,即:三者缺一不可,统一于税法。而且,无偿性要求强制性,强制性保障无偿性;而无偿性与强制性又共同决定固定性。从而结束新课讲授。3、课堂总结根据板书内容重新回顾本课学习的主要内容,包括税收的含义,以及税收的三个基本特征和它们之间的相互关系。4、作业布置让学生预习税收的种类的内容,尤其是增值税和个人所得税。同时了解父母每月所缴纳的个人所得税和怎么计算的。
第一环节:关于劳动光荣和就业的意义。这两个问题学生在自主阅读的基础上,教师设疑,给出两个人物事迹,一是农民工刘俊刚把青春献给第二个家乡的城市美容师;一是北大学子李彦宏自主创业,创建百度公司,启发学生比较、思考。很多学生倾向于要做李彦宏,教师则适时引导:难道清洁工的劳动不重要吗?经过辩论,归纳出劳动和就业的意义。接着利用教材中李师傅的事例,进行问题探究,“李师傅找不到工作的原因是什么?”从主客观两方面分析,带着问题进入到下一环节学习。第二环节:突出重点。多媒体展示:通过数字的列举及对占有材料的分析,既看到了我国就业形势严峻,也介绍了国家关注民生,实施积极的就业政策。在此基础上,教师启发学生归纳“我国就业严峻的原因及对策?”学生把教材理论与生活中的现实材料相结合,进行探究,得出就业形势严峻的主要原因及其相应对策。
环节三情景模拟 情感升华首先:1、本课开始观看的视频中:选出村长体现了村民参加选举的什么态度?生活中一些人“多我一票不多,少我一票不少,选举与我无关"的想法2、你如何看待上述两种不同态度?为什么?发表你的看法【教师这个过程中点拨、引导】如果我们都不珍惜自己的选举权,那么我们的国家将会出现什么后果?3、那么作为将来选民和被选举人,你们认为应具有那些政治素养才能适应?学生结合教材思考(1)(提示)不行使或不认真行使自己的选举权,意味着我们将不能选举出能为人民谋福利的当家人,意味着我们的国家将由重蹈旧中国的覆辙。(2)从态度上讲:公民应积极参加选举,认真行使这一权利,不断增强公民意识和主人翁意识,增强公民的参与感和责任感。(3)从能力上讲:要不断提高公民的政治参与能力(政治素质、文化素质、议政能力),在周全考虑、理性判断的基础上,郑重地投出自己的一票。
(2)世界观,人生观,价值观是人们文化素养的核心和标志。一旦形成就会对人产生深远持久的影响。(但随着生活阅历的变化,人们文化素养的提高,人们的“三观”会发生变化。)总之“潜移默化”指每时每刻,不知不觉;是从文化对人影响的过程来看的。“深远持久”指经年累月,难以抹去;是从文化对人影响的结果上说的。3.课堂总结:首先启动学生思维,教会学生把握知识主线,建构知识体系,先由学生进行总结,然后教师进行必要的补充4、布置作业:布置作业。运用文化对人的影响的知识分析“近朱者赤,近墨者黑”,并且应该如何处理朋友之间的关系。设计这个作业的意图是既让学生灵活运用所学知识,同时又让学生回归生活,如何处理朋友之间的关系。5、板书设计遵循板书设计的实用性、直观性的原则,根据本课的教材特点,我采用结构式板书,这样设计比较直观、系统,以便于学生能够系统把握和理解知识。
(1)文化与经济、政治在经济基础上相互影响。①经济、政治和文化是社会生活的三个基本领域。其中,经济是基础,政治是经济的集中表现,文化是经济和政治的反映。一定的文化由一定的经济、政治所决定,又反作用于一定的政治、经济,给予政治、经济以重大影响。②经济发展是文化发展的基础。但这并不意味着文化的发展始终与经济的发展亦步亦趋。如同不能简单地把精神文明看作是物质文明的派生物和附属品一样,也不能简单地认为文化是经济、政治的派生物和附属品。文化有其自身的传承性和相对的独立性。那种认为只要物质条件好了,精神文化自然而然地就会好起来,物质条件差一点,精神文化就不可能搞好的观点,不符合历史发展的事实,是不正确的。③掀开历史的画卷,文化既有古今和地域之别,又有先进与落后、腐朽之分。不同的文化,对经济、政治的影响不同,对社会发展的作用也不同。不同民族的文化,影响不同民族和国家各具特色的发展道路。
预测回答:成龙在影视,武术方面的价值,对于某个人,某个集团的价值。知识引导:人的价值体现在多方面的,可以是物质方面,也可以是精神方面,可以是对某个人或某个集团的价值,也可以是对人类和社会的价值。设置目的:从学生感兴趣的人物入手,分析对人的价值的评价。让学生自己分析总结,体现学生在新课改下的主体地位。从上述事例中我们可以看出人的价值是什么?如何评价?(学生活动)2.人的价值:在于创造价值,在于对社会的责任和贡献,即通过自己的活动满足自己所属的社会、他人以及自己的需要。(幻灯片显示)3.人的价值评价:看他的贡献,最根本的是对社会发展和人类进步事业的贡献。(幻灯片显示)老师总结:对社会的贡献并不是高高在上,不可触及。只要是做自己该做的事,从身边的小事做起,普普通通的劳动就是贡献社会和他人。学生归纳:人生价值原理二、价值观的导向作用(板书)1.价值观的含义人们在认识各种具体事物的价值的基础上,形成对事物价值的总的看法和根本观点。
(二)讲授新课:1、讲授重点:文化与经济、政治的关系。我首先带领学生分析课本上的活动探究,了解日常生活中的常见活动,让学生们观看视频材料帮助学生对文化活动、经济活动、政治活动进行辨别和分类。然后让学生们举例说明,综合探究,最后通过集体讨论得出文化与经济政治的关系:经济是基础,政治是经济的集中表现,文化是经济和政治的反映,一定的文化由一定的经济和政治决定,又反作用于政治和经济。这个问题是本课重点。要引导学生循序渐进,集体讨论,得出结论。2、突破难点:(1)文化与经济政治相互交融,在时代发展的进程中。首先播放上海世博会视频,让学生体会文化、经济、政治活动,另外我会引导学生积极举生活中的事例,来说明问题,让学生学会举一反三,充分理解这一知识,让学生明白文化与经济、政治的联系,让学生清楚文化渗透的力量有多大,帮助学生树立反对文化霸权主义的意识。
一、 教材分析1、地位和作用《文化创新的途径》是人教版教材高二政治必修3第二单元第五课第二个框题内容,本课是对全面两课的一个提升,同时对接下来学习第三、四单元的知识具有指导作用。文化创新是一个社会热点,具有很强的思想理论性和探索实践性。在前面两课中,学生基本明确了文化的交流、传播和发展;也明白了文化的继承和发展需要创新。而怎样进行创新是本节课探讨的内容,也是本单元的重点、难点和落脚点。2、教学目标(1)知识与能力目标:①识计文化创新的途径;理解文化创新过程中要认识和处理好两对基本关系:当代文化与传统文化、民族文化和外来文化的关系;②使学生初步具备认识和处理当代文化与传统文化、民族文化与外来文化关系的能力;使学生具备在合作、探究中体验生活、生成认识、构建知识的能力。
3、文化的力量。为了使学生能辨证地分析文化的力量,我设计了两个问题进行探讨:(1)是不是任何文化都能起促进作用?(2)你在听或唱国歌时感受到一种什么样的力量?这样,学生在对比中学会辨证地分析文化的力量——先进的、健康的文化能促进社会发展和个人成长;落后的、腐朽的文化则阻碍社会发展和个人成长。同时还能提高学生的文化赏析能力,从而引导学生装自觉参加健康有益的文化活动,抵制不良文化的影响,投身到社会主义精神文明建设中去。关于课堂练习,我准备了5个针对性比较强的选择题,从而加深巩固本框题的重难点知识。最后,播放歌曲《走进新时代》,展示本课知识结构,指出本框题需重点掌握的问题,结束本课教学。课后作业,我设计了这样一个辨析的题目:文化是人们创造的全部财富的总和,它是人类特有的现象。
二、学生情况分析(说学法)1、学生学习基础分析:学生通过对《生活与哲学》前面三个单元的学习,初步掌握了运用唯物论、辩证法、认识论的观点去认识问题、分析问题的能力;再通过对第十一课的学习,学生对马克思主义的历史观有了初步的理解,初步树立了正确的理想信念,这为本课教学目标的落实奠定了知识基础。 2、学生能力分析 :高二学生拥有一定生活体验,具备一定的信息收集和筛选能力、阅读能力、语言表达能力、对问题的一定的探究能力,同伴合作能力和具备初步逻辑思维能力。3、学生心理分析:在我国现阶段,以为人民服务为核心的社会主义道德建设过程中涌现了大批的先进人物和道德典范,但同时由于社会价值的多元化,个人主义、享乐主义、拜金主义等资本主义腐朽思想也同样在影响着当代的中学生。

一. 教材分析1. 本单元的中心话题是“计算机(Computers)”,内容涉及计算机的发展历史,计算机的应用等。本节课是该单元的第一课时,我将Warming up, Pre-reading and Comprehending这四部分整合为一节精读课。其中。Reading部分是题为WHO AM I?的文章,以第一人称的拟人手法介绍了计算机发长演变的历史和计算机在各个领域的应用,其主旨是表达计算机的发展变化之快以及在生活中用途之广。而Warming up部分以图片的形式展现了计算机的发展历程;Pre-reading中的问题和排序分别是为了预测语篇的内容和测试学生对计算机历史了解的情况;Comprehending则通过各项练习训练学生的阅读技能,从而加深对文章的理解。可见这几部分是一个有机的整体。2. 教学目标:1) 语言目标:重点词汇及短语:abacus, calculate, calculator, PC, laptop, PDA, robot, analytical, technological, universal, mathematical, artificial, intelligent, network, explore, in common, as a result.重点句子:a. My real father was Alan Turing, who in 1963 wrote a book to describe how computers could be made to work, and build a “universal machine” to solve any mathematical problem.
Ⅲ. Analysis of the teaching material:The topic of this unit is cultural relics. Students are quite interested in topics about different cultures around the world. This is the second period of the whole unit. As a reading class, the passage mainly talks about the history of the amber room (how it was made, sent as a gift, lost and rebuilt).According to the new national curriculum, when teaching reading, much emphasis should be put on training the students’ reading skills.Ⅳ. Teaching objectives1. Language objectives:1) Students are required to master the key words and phrases occurred in the passage (e.g. amazing, decorate, belong, in return, less than etc.)2) Students are required to learn the attributive clause and acquire the sentence pattern.2. 1) Students are required to describe a certain thing by using the new sentence patterns.2) Students are required to master two kinds of reading skills—skimming and scanning, and learn to use them in their daily reading.3. 1) Students are required to know the history of the amber room.2) Students are required to appreciate cultural relics and understand the importance of protecting them.Ⅴ. Teaching important and difficult points1) the new words, phrases, and sentence pattern in the course of reading.2) Teaching difficult point: Help the students master two kinds of reading skills—skimmingand scanning and learn to apply them in daily use.Ⅵ. Teaching methods:Task-based method & Top-down model Ⅶ. Teaching aids: PPT, pictures, blackboard Ⅷ. Teaching procedure:
Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times. The first and listening is extensive listening and the second and third listening is intensive listening. In the first time, They are required to listen a material including Part 1 and Part 2 and choose the best summary of the listening text. After they choose the right answer, They also need work in group to explain what is wrong with the others. Then I will make a conclusion that we should pay attention to the first paragraph and last paragraph and some keys to get the main idea. By doing this, their capacity of generalization will have a great improvement.Before the second listening, I will ask students to scan the blank on the power point quickly and ask them to note down some key words .Then ask them to listen to the Part 1again and fill the first column of the chart. Maybe some students just show the ideas of these three scientists an still can’t catch their development of gravity. Therefore, I will ask them to listen to Part 2 again and fill in the rest. After finish the listening, I will give them ten minutes to discuss with their partner. I will also guidethem to improve their answers when they discuss with others.
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill
