一、对教材分析1、地位和作用课程标准对本课的基本要求是:阐明科学发展观的涵义和说明全面建设小康社会的经济目标,最根本的是以经济建设为中心,不断解放和发展社会生产力。这一课在新教材中有着重要地位,且对我们的经济生活具有深远的指导意义和教育意义。同时对学生树立科学发展观有着重要的导向作用,对学生树立共同理想和远大理想有着重大的影响作用。因此,本课书是新教材的教育目的和归宿。2、教学目标(1)知识目标:了解总体小康水平的特征和全面建设小康社会的要求;理解科学发展观的科学内涵;运用促进国民经济又好又快发展的措施的基本要求。(2)能力目标 :能准确把握科学发展观科学内涵的理解能力;可以运用所学知识解决现实问题、参与经济生活的能力。(3)情感、态度与价值观目标:通过总体小康社会的建设增强民族自豪感;牢固树立科学发展观;增强节约意识;增强参与经济生活的自觉性。
(三)师生互动、巩固知识、课堂小结为培养学生的抽象思维能力和独立思考的能力,课堂小结让学生来总结,教师要向学生提示本课题主要讲了几个问题。并推荐一位擅长书法的同学书写。一方面可以展现该同学的书法技能,发挥其特长;另一方面对于其他同学也起到了模范带头的作用。(四)板书设计:板书设计准备采用条目式板书,条目式板书的作用是条理清楚、简练,一目了然,并且能够为学生做笔记乃至以后的复习提供方便。二、树立正确的消费观1、为什么要树立正确的消费观?(1)理论依据:生产与消费的辩证关系;(2)现实分析:关系到社会的整体利益;(五)课后作业注意观察自己的家庭消费情况,记录某时期的家庭各项消费支出,根据所学理论,判断自己家庭的消费结构是否合理。这有利于形成学生观察生活和观察身边的经济现象的习惯,培养思维能力和理财能力。又可以增强政治课的兴趣。
一、说教材(一)教材的地位与作用本节内容是本单元知识结构中重要的一环,具有承上启下的作用。由于各种天气现象的产生与大气的热力状况、大气的运动有密切的联系,所以,本课是在综合前两节内容的基础上,阐述常见的天气现象的成因。在实际生活中,天气系统与人们的生产、生活密切相关。本课所讲的内容对于学生了解天气变化的最基本因素,普及天气预报知识具有积极的意义。(二)教学目标(1)知识与技能目标:⑴从图片和简易图中,知道气团(冷气团、暖气团)的概念;锋的概念与分类;低压(气旋)、高压(反气旋)、高压脊、低压槽的概念。 ⑵从气温、气压、湿度、降水、风等几方面分析各种天气系统的形成及其气流特点,并综合出各种天气系统控制下的天气状况。⑶知道低压槽和高压脊概念及在图上的表示方法。(2)过程与方法目标:⑴让学生能阅读和简单分析天气图,解释天气变化现象;⑵用案例说明气象灾害发生的原因和危害;
(一)教材的地位与作用本节主要阐述太阳辐射和太阳活动对地球的影响。太阳辐射对地球的影响主要是从太阳为地球提供能量这个方面来阐述,通过图片的形式从四个方面来分析。不应让学生记忆这四个方面,需要归纳为:(1)直接或间接(化石燃料)为地球提供大部分能量。(2)维持四大圈层物质循环和能量交换,决定地理环境的基本特征。(二)教学目标(1)知识与技能目标:1.阐述太阳对地球的影响。太阳对地球的影响,包括太阳辐射对地球的影响和太阳活动对地球的影响。2.太阳辐射的概念、来源、波长等只作一般了解;太阳活动对地球影像是通过作用气候、地球电离层和磁场而发生的,主要包括磁暴、无线电短波通讯被干扰、极光和气候异常等。3.教材涉及太阳活动的概念、标志和周期需要明确,而太阳大气分层及对应太阳活动现象只作一般了解。
二、说学情学生对自然界中的水循环已具有一定的生活体验和知识基础,主要问题是学生还未上升到理性的层面上进行分析,而且自然界的水循环属于全球尺度和大尺度的地理现象,学生难以理解,需要教师创设适当的情境引导学生进行新知的建构。三、说教法(1)创设情景:教学实践证明,合理有趣的情境创设,可以引导学生快速进入角色,提高课堂效率(2)讨论法:通过组织学生讨论,给学生提供自主学习、合作学习、探究学习的机会。(3)多媒体演示法:利用多媒体播放一些直观的图片、动画和数字资料,把学生轻松得引入本课,通过形象生动直观地展现相关地理事物和现象,提高学生的感性认识,激发兴奋点,帮助他们理解课本内容。四、说学法(1)学会用图:让学生仔细观察图3.2和图3.3理解水循环的相关性(2)学会探究:学生思考分析总结水循环的地理意义及黄河断流的原因。
谈到这,如果有人会说这仅仅是在于我个人与战场之上,战场之下另当别论,那么,他完全错了。在我小学四年级的语文课上有两个人发言积极,一个姓黄,一个姓康,黄同学发言比康同学更积极,班上的同学常以为黄同学是个了不得的人物,后来,教语文的吴老师曾悄悄地告诉我:班上真正厉害的是康x,那黄x没什么,说的全是“一点通”上的,照搬不误。说到这,我还得厚着脸皮自夸一下,在四年级时,我和康同学是同坐,一次,老师叫我们对一片课文(好象是写黄继光舍身炸暗堡)的一个段落提问题时,我悄悄地对康同学说了一个问题,康同学对我说:“你站起来说嘛。”内向的我遥遥头,康同学便站举手,并起来将我的问题大声地说了出来,结果老师说:“恩,康x的问题提得很好。”
共享实验收集的信息,分享实验探究的结论,体验收获的乐趣。 小结拓展 这节课由大家感兴趣的球类运动和弹弓游戏,提出了功与速度变化关系的问题,利用倍增思想解决测量对物体做功的问题,使用我们熟悉的器材设计了探究方案,并进行实验探究,采用图像法进行数据处理,初步得出W∝V2的关系。在我们这节课探究以前,科学家就通过试验和理论的方法,已经总结出了功与速度变化的定量关系。人类社会也在社会生活和生产的各个领域予以利用。比如,古代的战争武器抛石器、大型弓弩,以及现代飞机弹射系统、还有机器人行走等等,希望同学在今后的学习中注意留心生活中的物理和社会中的物理。 领会总结。培养概括总结的能力,进一步巩固、感悟、提升实验探究中获得的思维能力及动手能力。感悟社会中的物理,认识物理学对科技进步以及文化和社会发展的影响。 列举学生知道的社会中做功使物体速度变化的例子,增强学生将物理知识应用于生活和生产的意识,培养学生的社会参与意识和对社会负责任的态度。
7.让学生阅读基因控制蛋白质合成的过程(转录,翻译)13分钟 动画演示“转录,翻译”过程两次,让学生有个整体印象。 培养学生自学习惯,突出教学过程中的学生为主体的教学思想。 8.配合动画引导学生根据预习逐段讲解。 注意问题(1)转录,翻译的地点,模板,生成物不同。因为这是一个极其复杂的过程,避免学生在学习过程中相混肴.(2)这个问题的阐明能为后面“密码子”的概念做好铺垫,避免学生搞不清“遗传密码”和“遗传信息”两个概念。 9.打出板书。 通过动画演示,加深学生的理解和掌握,提高学习效率。 10.重播全过程动画,引导学生讲述。7分钟 _x0007_加深认识,完成从量变到质变的飞跃。 11.过渡:就这样,以DNA为模板合成信使RNA,再以信使RNA为模板,以转运RNA为运载工具,使氨基酸在核糖体中按照一定的顺序排列起来,合成了与亲代一样的蛋白质,从而显现出与亲代同样的性状。从而引出“中心法则”。

3、重要语句的理解“可是一个人并不是生来要给打败的,你尽可把它消灭掉,可就是打不败他。”解析:这是老人第一次回合之后的内心独白,也是此小说的核心精神,充分体现了老人桑地亚哥的生命理念。整句话可以分为两部分来理解,前句告诉我们,人生活在自然与社会当中,必不可少要面临一些坎坷、磨难,这些磨难、坎坷完全可以造成躯体的消灭、消亡,这是人生命的脆弱性。后句,面对挫折,只要保持一种乐观的精神,拥有一颗坚强的心灵,那么,人类执着奋斗的精神将永不磨灭。4、象征主义题目是《老人与海》,而表明上,小说是写一位老人及其在海上的经历,但实际上,老人的形象极具概括性,他已经超越了一个人的存在,而成为了人生的一种象征。老人桑地亚哥就是“硬汉子”的代表,大海则是生命旅途的象征,鲨鱼则是我们行走中的“强物”,厄运的象征。人的一生不可能一帆风顺,不经历风雨,怎能见彩虹,走在人生路途中,不可避免我们都要遇到挫折,被厄运所阻挠,只有经历与“鲨鱼”的较量,才能成为强者,唱出最美的歌。

在学生活动的基础上,教师总结归纳:要坚持从群众中来到群众中去的工作方法。要求:政府要通过各种途径,利用各种群众组织、社会团体广泛收集群众意见和建议,认真对待群众的来信来访。还要为群众诚心诚意办实事,尽心竭力解难事,坚持不懈。通过合作探究,以此来培养学生的分析能力,探究能力以及透过现象看本质的能力,培养学生获取信息的能力,自主学习的能力以及全面看问题的能力,再结合教师的讲授,给学生一种茅塞顿开的感觉。环节四 回归生活 提升情感我将引导学生阅读课本,通过设置活动探究课,结合生活实际从时效,便利,实效等方面请学生评述公民求助或投诉的四种方式的特点和优点。在这一过程中,我还会用多媒体展示常用的热线电话,政府网站上有关信访、政务公开及其他便民利民的栏目,丰富课堂资源。让学生阅读课本,自行归纳知识点,有助于培养学生自主学习能力。
(明确:“寡人之于国也,尽心焉耳矣”,但“寡人之民不加多,何也?”)②他认为自己对国家政务尽心尽力了,他有哪些具体做法?(明确:移民移粟)③第2—4节中孟子是怎样说明梁惠王移民移粟的措施与“邻国之政”并无本质区别的?(明确:孟子不直接回答“民不加多”的问题,而是用梁惠王熟悉的“战”设喻——设圈套,诱使对方在不知不觉中说出“不可,直不百步耳,是亦走也。”)④孟子认为怎样才能做到“王道之始”?要想“王道之成”还需采取哪些措施?(明确:“不违农时,谷不可胜食也。数罟不入氵夸池,鱼鳖不可胜食也。斧斤以时入山林,材木不可胜用也。谷与鱼鳖不可胜食,材木不可胜用五亩之宅,树之以桑,五十者可以衣帛矣。鸡豚狗彘之畜,无失其时,七十者可以食肉矣。百亩之田,勿夺其时,数口之家,可以无饥矣。谨库序之教,申之以孝涕之义,颁白者不负戴于道路矣。)这一小步的目的是想让学生通过这些问题的解答,可以进一步理清思路,掌握文的大概内容。
