  • 人教版高中政治必修3在文化生活中选择说课稿

    一、教材分析文化市场和大众传媒的发展,给我们的文化生活带来了许多可喜的变化。但是,文化市场的自发性和传媒的商业性也引发了令人忧虑的现象。文化生活有“喜”也有“忧”,让我们欢喜让我们忧。面对形式多样的文化生活,置身于文化生活的海洋之中,在文化生活中如何选择、怎样作出正确的选择是亟待向学生解决的问题。二、学情分析高二学生处于世界观、人生观和价值观形成的关键时期,身心迅速发展,自我意识和独立性较强,社会公共生活空间范围越来越大,并且开始理性地思考社会和人生的重大问题,他们可塑性强,但情绪仍然不稳定,有多变性,容易冲动或偏激,迫切需要提升思想意识,加强方法论的指导,使其在纷繁复杂的文化生活中能够进行正确的判断与选择。如果我们的学生不能把握正确的航向,是非观念模糊,良莠不分,就会陷入落后文化和腐朽文化的泥沼而不能自拔,甚至造成无法挽回的恶果。

  • 人教版高中政治必修2中国走和平发展道路说课稿

    教师点评:根据小论文的写作情况对小论文给予肯定,同时指出其有待修改的地方。学生在写小论文的时候是根据教材中的提示来写的,所以对于教材中的这些提示,可以作一个说明。如“在发展的过程中,我们面对怎样的挑战和困难”,对于这点,学生可能会出现片面看问题的不足,一旦这种情况出现,我们就要及时进行说明:我们面临的挑战和困难既有来自国内的,也有来自国际的,引导学生学会用全面的观点分析问题。教师引导学生明确作为中学生可以从以下方面去作准备:第一,要有国家观念、民族意识,不断增强民族自豪感、自尊心和自信心;第二,关注国家大事;第三,自自觉履行维护国家统一和民族团结的义务,维护国家安全、荣誉和利益;第四,努力学好科学文化知识,提高自己的科学文化素质和思想道德素质,增强各个方面的能力,掌握振兴中华民族的本领,这也是中学生最需要做到的。通过探究活动,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。

  • 高中历史人教版必修一《第2课秦朝中央集权制度的形成》说课稿

    【课件展示】《秦朝中央集权制度的建立》《教材简析》《教学目标》《教法简介》《教学过程设计及特色简述》【师】本节内容以秦代政治体制和官僚系统的建立为核心内容,主要包括秦朝中央集权制的建立的背景、建立过程及影响。本节内容在整个单元中起到承前启后的作用,在整个模块中也有相当重要的地位。让学生了解中国古代中央集权政治体制的初建对于理解我国古代政治制度的发展乃至我们今天的政治体制是十分必要的。 本堂课我采用多媒体和讲授法及历史辩论法相结合,通过巧妙设计问题情境,调动学生的学习积极性,使学生主动学习,探究思考。教师引导和组织学生采取小组讨论、情景体验等方式,达到教学目标。 本节内容分三个部分,下面首先看秦朝中央集权制度建立的前提即秦的统一

  • 人教版高中政治必修4认识运动把握规律说课稿(二)

    归纳:第一句正确。承认运动的绝对性。第二句错误。否认相对静止的存在。3.课堂小结,强化认识(2—3分钟)课堂小结,可以把课堂传授的知识尽快地转化为学生的素质;简单扼要的课堂小结,可使学生更深刻地理解政治理论在实际生活中的应用,并且逐渐地培养学生具有良好的个性。人类社会是物质世界长期发展的产物,世界的本质是物质,世界的真正统一性就在于它的物质性,物质又是运动的,运动的形式多种多样,运动又是物质的运动,物质和运动是不可分割的,运动和静止既有区别又有联系,物质的运动是绝对的、无条件的和永恒的,而静止是相对的、有条件的和暂时的。4.板书设计我比较注重直观,系统的板书设计,还及时地体现教材中的知识点,以便于学生能够理解掌握。

    (7)精讲即精讲点拨,释疑解难。现代教育理论一方面强调学生学习的主动性;另一方面也重视发挥教师的积极性。课堂活动的主动性、合理性、有效性的实现还有赖于教师的讲。精讲就要求教师的讲授内容精要,分析精辟,语言精彩、节奏精练、点拨精当。从内容上看,本节课精讲主要有三处:一、运动的含义;二、运动是物质的根本属性;三、静止是运动的特殊状态。2、教学手段多媒体辅助教学。六、教学过程第一步:创设情景,用“谜语”导入新课。使学生置身于教学内容的情景之中,产生继续探究的强烈愿望。第二步:运用直观、形象的画面将教学目标问题,唤起学生参与欲望,驱使学生去思考,去自读。第三步:引导学生相互讨论,实现学生之间的横向交流。第四步:教师依据反馈信息,给予重点讲授、提示点拨、搭桥铺路。第五步:设置故事型的模拟法庭,开展讨论,在高潮中结束新课。第六步:总结概括,深化知识,形成网络。

He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner.

  • 人教版高中数学选择性必修二等比数列的概念 (2) 教学设计

    二、典例解析例4. 用 10 000元购买某个理财产品一年.(1)若以月利率0.400%的复利计息,12个月能获得多少利息(精确到1元)?(2)若以季度复利计息,存4个季度,则当每季度利率为多少时,按季结算的利息不少于按月结算的利息(精确到10^(-5))?分析:复利是指把前一期的利息与本金之和算作本金,再计算下一期的利息.所以若原始本金为a元,每期的利率为r ,则从第一期开始,各期的本利和a , a(1+r),a(1+r)^2…构成等比数列.解:(1)设这笔钱存 n 个月以后的本利和组成一个数列{a_n },则{a_n }是等比数列,首项a_1=10^4 (1+0.400%),公比 q=1+0.400%,所以a_12=a_1 q^11 〖=10〗^4 (1+0.400%)^12≈10 490.7.所以,12个月后的利息为10 490.7-10^4≈491(元).解:(2)设季度利率为 r ,这笔钱存 n 个季度以后的本利和组成一个数列{b_n },则{b_n }也是一个等比数列,首项 b_1=10^4 (1+r),公比为1+r,于是 b_4=10^4 (1+r)^4.

    二、典例解析例3.某公司购置了一台价值为220万元的设备,随着设备在使用过程中老化,其价值会逐年减少.经验表明,每经过一年其价值会减少d(d为正常数)万元.已知这台设备的使用年限为10年,超过10年 ,它的价值将低于购进价值的5%,设备将报废.请确定d的范围.分析:该设备使用n年后的价值构成数列{an},由题意可知,an=an-1-d (n≥2). 即:an-an-1=-d.所以{an}为公差为-d的等差数列.10年之内(含10年),该设备的价值不小于(220×5%=)11万元;10年后,该设备的价值需小于11万元.利用{an}的通项公式列不等式求解.解:设使用n年后,这台设备的价值为an万元,则可得数列{an}.由已知条件,得an=an-1-d(n≥2).所以数列{an}是一个公差为-d的等差数列.因为a1=220-d,所以an=220-d+(n-1)(-d)=220-nd. 由题意,得a10≥11,a11<11. 即:{█("220-10d≥11" @"220-11d<11" )┤解得19<d≤20.9所以,d的求值范围为19<d≤20.9

(1) 求从正方形ABCD 开始,连续10个正方形的面积之和;(2) 如果这个作图过程可以一直继续下去,那么所有这些正方形的面积之和将趋近于多少?分析:可以利用数列表示各正方形的面积,根据条件可知,这是一个等比数列。解:设正方形的面积为a_1,后续各正方形的面积依次为a_2, a_(3, ) 〖…,a〗_n,…,则a_1=25,由于第k+1个正方形的顶点分别是第k个正方形各边的中点,所以a_(k+1)=〖1/2 a〗_k,因此{a_n},是以25为首项,1/2为公比的等比数列.设{a_n}的前项和为S_n(1)S_10=(25×[1-(1/2)^10 ] )/("1 " -1/2)=50×[1-(1/2)^10 ]=25575/512所以,前10个正方形的面积之和为25575/512cm^2.(2)当无限增大时,无限趋近于所有正方形的面积和
