二、流动镶嵌模型的基本内容1、膜的成分2、膜的基本支架3、膜的结构特点4、膜的功能特性设计意图:我根据板书的“规范、工整和美观”的要求,结合所教的内容,设计了如图所示的板书,使学生对本节课有一个整体的思路。八、教学反思:本节课我创设了问题情境来引导学生主动学习,利用了多媒体信息技术激发学生的学习热情,调动了学生的积极性,成功实现预期的教学目标。体现了学生为主体地位的新课程理念。启发式、探究式的教学方法以及由教师指导下的学生自主阅读、合作交流的学习方法把学生从死记知识的苦海中解救出来。初次的尝试还存在一定的缺陷,学生不能够很好的把知识和习题联系,只是把他所知道的知识简单罗列,不能够体现出能力的训练。在上课中发现学生比较腼腆或拘束,声音比较小,表达不能到位。尽管本节课存在诸多不足之处,但是也让我看到了闪光点:学生比较欢迎这样一堂自己是主角的课堂。
2、讲授新课:(35分钟)通过教材第一目的讲解,让学生明白,生活和学习中有许多蕴涵哲学道理的故事,表明哲学并不神秘总结并过渡:生活也离不开哲学,哲学可以是我正确看待自然、人生、和社会的发展,从而指导人们正确的认识和改造世界。整个过程将伴随着多媒体影像资料和生生对话讨论以提高学生的积极性。3、课堂反馈,知识迁移。最后对本科课进行小结,巩固重点难点,将本课的哲学知识迁移到与生活相关的例子,实现对知识的升华以及学生的再次创新;可使学生更深刻地理解重点和难点,为下一框学习做好准备。4、板书设计我采用直观板书的方法,对本课的知识网络在多媒体上进行展示。尽可能的简洁,清晰。使学生对知识框架一目了然,帮助学生构建本课的知识结构。5、布置作业我会留适当的自测题及教学案例让同学们做课后练习和思考,检验学生对本课重点的掌握以及对难点的理解。并及时反馈。对学生在理解中仍有困难的知识点,我会在以后的教学中予以疏导。
五.说教学过程:(重点)1.课题引入:课堂探究导入新课。采用教材现成的探究活动导入新课,既“温故”又“知新”,还节约了课堂有效时间。2.讲授新课:(20-25分钟)本课的重难点是关于哲学基本问题的解释,我引用一个很著名的学生也略知一二的唯心主义观点的例子(课堂探究1)顺利进入本课重要知识点的学习,采用案例教学,激发学生的兴趣以及探究问题的欲望,学习哲学基本问题的第一个方面,并用问题和练习形式巩固知识,强化学生易错已混知识点;课堂探究2,同样引用哲学上的著名案例让学生分析探究思考以及合作交流,学生趣味浓厚,主动深入学习本课知识,达到预期教学目的。此时,本课的重点知识教学完成。关于本课的第二个知识点“为什么思维和存在的关系问题是哲学的基本问题”采用学生自主阅读、合作交流的方法,归纳总结,完成本知识目标。3.课堂反馈、知识迁移(10-15分钟)采用学生总结、随堂练习等形式巩固本课知识,同时检验教学效果。可使学生更深刻的理解教学重点。
函数在高中数学中占有很重要的比重,因而作为函数的第一节内容,主要从三个实例出发,引出函数的概念.从而就函数概念的分析判断函数,求定义域和函数值,再结合三要素判断函数相等.课程目标1.理解函数的定义、函数的定义域、值域及对应法则。2.掌握判定函数和函数相等的方法。3.学会求函数的定义域与函数值。数学学科素养1.数学抽象:通过教材中四个实例总结函数定义;2.逻辑推理:相等函数的判断;3.数学运算:求函数定义域和求函数值;4.数据分析:运用分离常数法和换元法求值域;5.数学建模:通过从实际问题中抽象概括出函数概念的活动,培养学生从“特殊到一般”的分析问题的能力,提高学生的抽象概括能力。重点:函数的概念,函数的三要素。难点:函数概念及符号y=f(x)的理解。
例7 用描述法表示抛物线y=x2+1上的点构成的集合.【答案】见解析 【解析】 抛物线y=x2+1上的点构成的集合可表示为:{(x,y)|y=x2+1}.变式1.[变条件,变设问]本题中点的集合若改为“{x|y=x2+1}”,则集合中的元素是什么?【答案】见解析 【解析】集合{x|y=x2+1}的代表元素是x,且x∈R,所以{x|y=x2+1}中的元素是全体实数.变式2.[变条件,变设问]本题中点的集合若改为“{y|y=x2+1}”,则集合中的元素是什么?【答案】见解析 【解析】集合{ y| y=x2+1}的代表元素是y,满足条件y=x2+1的y的取值范围是y≥1,所以{ y| y=x2+1}={ y| y≥1},所以集合中的元素是大于等于1的全体实数.解题技巧(认识集合含义的2个步骤)一看代表元素,是数集还是点集,二看元素满足什么条件即有什么公共特性。
(一)强举措,营造良好政策环境。一是增强政策叠加效应。根据中央、省相关政策,立足我市实际,召开全市民营经济发展大会,出台《关于促进民营经济高质量发展的实施意见》,从降成本、助融资、破壁垒、促转型、拓市场、保权益等六个方面制订25项政策措施。市有关部门相继研究制定15个实施细则,形成一系列政策体系,增强政策可操作性。二是加强政策宣传解读。通过电视、报纸、网络等主流媒体和政府门户网站等,采取多种形式,大力宣传和深入解读促进民营经济高质量发展有关政策,提高政策知晓度。三是建立政策落实机制。各级政府部门根据工作推进要求,跟踪分析政策执行情况,定期报告存在问题,共同会商解决办法,确保政策落地见效,提振企业发展信心。
培养学生合作交流意识和探究问题的能力,这一部分知识层层递进,符合学生由特殊到一般、由简单到复杂的认知规律。4、互动探究(1)极限思想的渗透让学生阅读“思考与讨论”小版块.培养学生的自学和阅读能力提出下列问题,进行分组讨论:a、用课本上的方法估算位移,其结果比实际位移大还是小?为什么?b、为了提高估算的精确度,时间间隔小些好还是大些好?为什么?针对学生回答的多种可能性加以评价和进一步指导。让学生从讨论的结果中归纳得出:△t越小,对位移的估算就越精确。渗透极限的思想。通过小组内分工合作,讨论交流,培养学生交流合作的精神,以及搜集信息、处理信息的能力;通过小组间对比总结,使学生学会在对比中发现问题,在解决问题过程中提高个人能力;
设计意图:几道例题及练习题,其中例1小车由静止启动开始行驶,以加速度 做匀加速运动,求2s后的速度大小?进而变式到:小车遇到红灯刹车……,充分体现了“从生活到物理,从物理到社会”的物理教学理念;例题及练习题由浅入深、由易到难、各有侧重,体现新课标提出的让不同的学生在物理上得到不同发展的教学理念。这一环节总的设计意图是反馈教学,内化知识。(6) 小结归纳,拓展深化我的理解是,小结归纳不应该仅仅是知识的简单罗列,而应该是优化认知结构,完善知识体系的一种有效手段,为充分发挥学生的主题作用,从学习的知识、方法、体验是那个方面进行归纳,我设计了这么三个问题:① 通过本节课的学习,你学会了哪些知识;② 通过本节课的学习,你最大的体验是什么;③ 通过本节课的学习,你掌握了哪些学习物理的方法?
(3)改造主观世界同改造客观世界的关系。改造客观世界同改造主观世界,是相互联系、相互作用的。改造主观世界是为了更好地改造客观世界,人们在改造客观世界的同时也改造着自己的主观世界。通过自觉改造主观世界,又能提高改造客观世界的能力。师:人们对自己的思想道德境界的追求,是永远止境的。让我们共同努力,在践行社会主义思想道德的过程中,不断追求更高的目标,像无数先辈那样,加入到为共产主义远大理想而奋斗的行列中吧!课堂小结通过本节课学习使我们认识到面对现实生活中的思想道德冲突,加强知识文化修养和思想道德修养,不断追求更高的思想道德目标的必要性;把握了知识文化修养与思想道德修养的含义及其相互关系;明确了我们应该和怎样追求更高的思想道德目标;认识到这是一个永无止境的过程。我们要脚踏实地,从现在做起、从点滴小事做起,不断提高知识文化修养和思想道德修养,追求更高的思想道德目标。

The topic of this part is “Describe a place with distinctive cultural identity”.This section focuses on Chinese culture by introducing Chinatown, whose purpose is to show the relationship between the Chinese culture and American culture. The Chinese culture in Chinatown is an important part of American culture. Chinatown is an important window of spreading Chinese culture and the spirit homeland of oversea Chinese, where foreigners can experience Chinese culture by themselves.Concretely, the title is “Welcome to Chinatown!”, from which we can know that the article aims at introducing Chinatown. The author used the “Introduction--Body Paragraph--Conclusion” to describe the people, language, architecture, business, famous food and drinks and people’s activities, which can be a centre for Chinese culture and shows its unique charm.1. Read quickly to get main idea; read carefully to get the detailed information.2. Learn the characteristics of writing and language.3. Learn to introduce your own town according to the text.4. Learn to correct others’ writing.1. Learn the characteristics of writing and language.2. Learn to introduce your own town according to the text.Step 1 Lead in ---Small talkIn the reading part, we mentioned the Chinatown of San Francisco. How much do you know about Chinatown of San Francisco ?Chinatown is a main living place for Chinese immigrants, where you can see many Chinese-style buildings, costumes, operas, restaurants, music and even hear Chinese.Step 2 Before reading ---Predict the contentWhat is the writer’s purpose of writing this text ? How do you know ?From the title(Welcome to Chinatown) and some key words from the text(tourist, visit, visitors, experience), we can know the purpose of the text is to introduce Chinatown and show the relationship between Chinese culture and American culture.
1. In Picture 1 and Picture 2, where do you think they are from? How do you know?From their wearings, we can know they are from ethnic minority of China--- Miao and Dong.Picture 1, they are playing their traditional instrument lusheng in their traditional costumes.Picture 2. the girls are Miao because they wear their traditional costumes and silver accessory.2. In Picture 3, can you find which village it is? What time is it in the picture?It is Dong village. It is at night. Step 2 While-listeningJustin met a new friend while traveling in Guizhou. Listen to their conversation and complete the summaries below.Part 1Justin and Wu Yue watched some Miao people play the lusheng. The instrument has a history of over 3,000 years and it is even mentioned in the oldest collection of Chinese poetry. Then they watched the lusheng dance. Justin wanted to buy some hand-made silver/traditional accessories as souvenirs. He was told that the price will depend on the percentage of silver. Part 2They will go to a pretty Dong minority village called Zhaoxing. they will see the drum towers and the wind and rain bridges. They may also see a performance of the Grand Song of the Dong people.Step 3 Post-listening---TalkingWork in groups. Imagine Justin is telling some friends about his trip to Guizhou. One of you is Justin and the rest of you are his friends. Ask Justin questions about his trip and experience. The following expressions may help you.
生2:每逢清明,或其他一些死者的纪念日,人们总要为死去的亲人烧纸钱。这幅漫画由烧纸钱演变为烧“家电”,说明随着社会环境的变化,人们根深蒂固的一些封建思想,还在影响着人们的生活。要花大力气去破除封建迷信活动。师:说到底,算命、烧纸钱是封建迷信活动,从文化角度来说,是落后文化。我们一起来看看在现实生活中,还有哪些落后文化在影响着人们的生活。生1:在一些边远落后地区,大人小孩生了病,不是看医生,而是让巫婆神汉来治,结果往往耽误了诊疗时间,有的甚至还丢掉了性命。生2:“重男轻女”“多子多福”,红白事大操大办现象在有些地方还很严重。师:这些落后文化都有哪些共同特征?在你看来,这些现象有哪些危害?生3:这些落后文化,在内容上带有迷信、愚昧、颓废、庸俗等色彩,在形式上常常以传统习俗的形式表现出来,如人们常见的看相、算命、测字、看风水等。它会麻痹人的意志,使人消极、悲观、绝望,对理想、前途、信念丧失信心;破坏社会的风气。
三、下一步工作举措一是抓招商,提升项目建设质效:建立健全新的招商引资工作机制,开展重大项目招商和重大产业项目建设攻坚行动,推行“五个一”项目推进机制,管委会一周一调度,一月一讲评。二是抓服务,提升营商环境品位:首先提升干部职工的服务水平;其次强化要素保障,抓好闲置土地和僵尸企业清理,储备土地300亩、建标准化厂房x万平方米,盘活资产提高土地利用率;再次,完成机构改革和赋权改革,实现园区事园区办。三是抓创新,提升产业发展水平:围绕电子陶瓷产业园等专业园区发展建设和产业承载情况,培育一批科技创新项目;扶持企业科技创新,提高产品科技含量和附加值。四是抓转型,提升园区发展动力:围绕打造园区孵化、科技创新、金融服务、人才培养、共建共享等x大平台发力;进一步完善路网等基础设施;开启梅苑工业园产城融合建设;严守安全生产和环境保护两条底线。
由此引导学生的深思,学生通过合作探究,帮助学生认识到不注重思想道德修养,即使掌握了丰富的科学知识,也难以避免人格上的缺失,甚至危害社会。进而总结出关系二:加强思想道德修养,能够促进科学文化修养。科学文化修养的意义播放感动中国人物徐本禹先进事迹短片。学生观看完视频后,思考:从徐本禹的事迹中,我们可以了解到我们加强科学文化修养的根本意义是什么?引导学生结合自身体会,发表各自见解,在此基础上帮助学生总结出,要使自己的思想道德境界不断升华,为人民服务的本领不断提高,成为一个真正有知识文化涵养的人,成为一个脱离低级趣味的人、有益于人民的人。知识点三:追求更高的思想道德目标根据教材110探究活动(思想道德的差异、反应人们世界观、人生观、价值观的差异)思考:用公民的基本道德规范来衡量这些观点,你赞成哪些观点?反对哪些观点?小组进行合作探究,引导学生根据公民基本道德规范对这些价值观进行评析。
1.做学问之前首先学会做人2.知识文化修养和思想道德修养的关系三.追求更高的思想道德目标㈤ 说教学评价和反思:1.这节课主要是以学生为主体,老师为主导,让学生充分发表自己的看法,把理论的知识结合在实际的日常生活中,鼓励学生充分发表自己的意见,能调动学生学习的积极性,达到教学目的。这节课学生讨论,发言的机会很多,但由于我校的学生的基础薄弱,在发言时难免偏离老师引导的方向,甚至出现毫不相干的说法,由于本人经验不够此时如何去引导他们可能做的还不够好。2.新课程的教学,如何突破书本知识的局限,延伸更深层次的内容是一个难题。本节课在知识的处理上,把道德的重要性与道德的层次两个知识点补充了进去,目的是让学生在学习之前有一个情感的铺垫,从而更好地达到教学目标。
反思感悟用基底表示空间向量的解题策略1.空间中,任一向量都可以用一个基底表示,且只要基底确定,则表示形式是唯一的.2.用基底表示空间向量时,一般要结合图形,运用向量加法、减法的平行四边形法则、三角形法则,以及数乘向量的运算法则,逐步向基向量过渡,直至全部用基向量表示.3.在空间几何体中选择基底时,通常选取公共起点最集中的向量或关系最明确的向量作为基底,例如,在正方体、长方体、平行六面体、四面体中,一般选用从同一顶点出发的三条棱所对应的向量作为基底.例2.在棱长为2的正方体ABCD-A1B1C1D1中,E,F分别是DD1,BD的中点,点G在棱CD上,且CG=1/3 CD(1)证明:EF⊥B1C;(2)求EF与C1G所成角的余弦值.思路分析选择一个空间基底,将(EF) ?,(B_1 C) ?,(C_1 G) ?用基向量表示.(1)证明(EF) ?·(B_1 C) ?=0即可;(2)求(EF) ?与(C_1 G) ?夹角的余弦值即可.(1)证明:设(DA) ?=i,(DC) ?=j,(DD_1 ) ?=k,则{i,j,k}构成空间的一个正交基底.
师:在科学发展过程中,前一个理论体系的不完善之处,往往是新的研究和新的发现的突破口。开普勒之后,意大利天文学家伽利略创制了天文望远镜,用更加精确的观察继续发展和验证哥白尼创立的新天文学理论。除了用望远镜进行天文观察以外,伽利略还开始进行自然科学的实验研究,哪位同学能给大家讲一讲伽利略在比萨斜塔上所作的关于物体自由下落的实验?生:(讲述这一实验)师:所以,伽利略在科学方面更加重要的贡献是奠定了近代实验科学的基础。(2)实验科学和唯物主义师:伽利略从实践上开辟了实验科学的方法,而英国唯物主义哲学家培根则从理论上阐述了实验科学的方法——归纳法。培根和伽利略同被称为实验科学之父,培根还有一句影响深刻的名言:“知识就是力量”,表明了他注重知识,尊崇科学的精神。我们再来概括一下意大利哲学家布鲁诺的唯物主义思想,是否有同学可以简述布鲁诺的生平事迹?
The topic of this part is “Discover the reasons for festivals and celebrations.The Listening & Speaking & Talking part aims at talking about the experiences and feelings or emotions about the festivals and celebrations. This section aims at detecting the reason why the people celebrate the festivals, the time, the places, the types and the way of celebrations.
