  • 人教版新课标小学数学二年级下册求一个数是另一个数几倍的除法应用题说课稿2篇

    一、说教材表内除法二单元主要内容有:7.8.9的乘法口诀求商,解决用除法计算的简单的实际问题,综合应用乘,除法计算的稍复杂的实际问题。本单元的目标是着重让学生在熟练掌握用口诀求商一般方法的基础上,综合应用表内乘除法的计算技能解决一些简单和稍复杂的涉及乘,除运算的实际问题。今天所教学的内容是解决问题中的第一个内容,求一个数是另一个数的几倍是多少,这课时的主要目标是:1、联系实际问题理解"一个数是另一个数的几倍"的含义,体会数量之间的相互关系;会用自己的语言表达解决问题的大致过程和结果。2、根据"倍"的概念和除法的含义,分析、推理、探究"求一个数是另一个数的几倍"的实际问题的一般方法;经历将"求一个数是另一个数的几倍是多少"的实际问题转化成"求一个数里面有几个另一个数"的数学问题的过程,初步学会用转化的方法来解决简单的实际问题。

  • 人教版新课标小学数学四年级下册将较大数改写成用万或亿作单位的数说课稿2篇

    一、说教材该内容是人教版小学数学四年级第八册第四单元的最后一个内容,是在学生已经掌握了把整万、整亿数改写成用万或亿作单位的数的基础上进行教学的。通过本节课的学习,要使学生能通过独立思考、合作交流,掌握把大数目改写成用“万”或“亿”作单位的数的方法,为以后能准确、恰当地运用数目描述生活现象打下良好的基础。根据本课的内容和学生已有的知识和心理特征,我制订如下教学目标:1、掌握把较大数改写成用“万”或“亿”作单位的数的方法,并能根据要求保留一定的小数位数。2、经历将一个数改写成用“万”或“亿”作单位的数的过程,体验数据记法的多样性。3、感受数学知识的应用性。理解和掌握把较大的数改写成用“万”或“亿”作单位的小数的方法是本课的教学重点。位数不够用0补足是本节课的难点。

  • 人教版新课标小学数学六年级下册比例的意义和基本性质说课稿2篇

    4.教学比例的各部分名称这部分的教学,我采用了阅读自学法。实施素质教育,使学生由“学会”变“会学”,这里我注重培养学生的自学能力,师生的双边关系亦实现从扶到放的转变。在学生自学课本时,老师写出比例的两种形式,引导学生注意内项和外项的位置。5.教学比例的基本性质观察80:2=200:5中的两个内项的积与两个外项的积的关系,引导学生把两个外项与两个内项分别相乘,比较结果,然后引导他们回答:2:3 = 0.4:0.6。两个内项的积与两个外项的积有什么关系?再让学生归纳出比例的基本性质,探讨写分数形式,归纳“交叉相乘”积相等。小结:比例的基本性质可以检验组成的比例对不对?并提问:4:9=5:10成立吗?比例的基本性质是本课的第二个重点。为了突出重点,我引导学生通过计算几个比例式的内项积和外项积,也从特殊到一般的推理方式,引导学生发现规律,总结概括性质。同时也渗透了实践第一的观点。

  • 人教版新课标小学数学三年级下册两位数乘两位数的乘法(不进位)说课稿2篇

    得出这样便于口算的道理,也为帮助学生探索“两位数乘两位数”的竖式计算方法埋下了伏笔。与此同时也允许学生把12用他们认为更便于计算的方法进行计算。另一种是直接用竖式计算。竖式的摆法学生肯定没问题,对于第一步如何计算也难不倒学生,关键是第二步、第三步,通过学生自己探索算法,让学生弄清第二步、第三步为什么这样写?根据学生的汇报,强调书写格式并板书,用个位上的2去乘24,乘得的积是表示48个一,积的末尾要和个位对齐;用十位上的1去乘24,乘得的积表示24个十,乘得积的末尾要和十位对齐(个位上的0省略不写);最后把两次乘得的积相加。(这样利用迁移原理,使学生一步一步地加深对算理和算法的认识和理解,不但突出了教学重点,而且突破了教学难点。)3、教师点拨:笔算乘法时:(1)从个位乘起,先用第二个因数的个位上的数依次去乘第一个因数的每一位上的数,得数末位和第一个因数的个位对齐;

  • 人教版新课标小学数学六年级上册百分数和分数、小数的互化说课稿2篇

    二、以人为本,说策略。《数学课程标准》指出:“数学教学要紧密联系学生的生活实际,从学生的生活经验和已有的知识出发……”因此,结合本课教材特点、学生实际情况,我采取小组合作学习,引导学生应用学过的分数、小数互化的知识进行迁移、类推,学习新知识。同时,让学生在尝试探究的积极活动中获取新知,发展能力。三、以探为主,说流程。课堂教学是学生数学知识的获得、技能技巧的形成、智力、能力的发展以及思想品德的养成的主要途径。为了达到预期的教学目标,我对整个教学过程进行了系统地规划,遵循目标性、整体性、启发性、主体性等一系列原则进行教学设计。设计了以下几个主要的教学程序:(一)设疑激趣,引入课题。“兴趣是最好的老师”,为了激发学生的学习兴趣,课一开始,我设计了一个童话故事,在故事中设计了帮助主人公比较2/5、42%、0.45的问题,然后引出课题。

  • 人教版高中历史必修2从“战时共产主义”到“斯大林模式”教案

    5、弊端:(1)经济发展不均衡,片面发展重工业,使轻工业和农业长期处于落后状态;(2)对农民的剥夺太重,挫伤了农民的生产积极性;(3)长期执行指令性计划严重削弱了企业的生产自主权,不利于发挥企业的生产积极性,制约了苏联经济的可持续发展。(4)计划经济体制确立后,没有随着社会的变化进行调整,二战后逐渐僵化,丧失了自我完善的功能,成为苏联解体的重要因素。【合作探究】斯大林模式的评价及经验教训:积极:①使苏联迅速实现了 工业化②苏联经济实力的迅速增长,为反法西斯战争的胜利奠定了 物质基础 。消极:①政治:高度集权,破坏了 民主与法制 ; ②经济:优先发展重工业使 农业和轻工业长期处于落后状态,农民生产积极性不高;计划指令,压制了地方和企业的积极性,阻碍苏联经济的发展高度集中的计划经济体制,成为东欧剧变和苏联解体的重要原因。

  • 人教版高中历史必修3从“师夷长技”到维新变法教案

    4、维新思想推动下的变法运动虽然失败了。但这是中国近代真正意义上的一次思想解放潮流,为什么?展开:维新派提倡西学,兴民权,对封建专制制度和传统观念进行了冲击,促进了中国人民的觉醒,为资产阶级民主思想的传播奠定了基础,具有思想解放的启蒙作用。是一次救亡图存的爱国运动,也是一次发展资本主义的改革运动;他们提倡资产阶级新学,批判封建主义旧学,引导人们重新认识世界,他们痛感民族危机的严重,号召人们奋起救国,谋求国家的独立富强;给古老的中国社会注入的活力是不可低估的,站在历史长河的高度看,由传统农耕社会向近代工业社会转变是一股不可抗拒的历史潮流,尽管它在19世纪末的中国遭到了暂时挫折,但对清朝的封建专制统治却是一次巨大的强烈的冲击波,它留下的痕迹是永不磨灭的,是永远鼓舞与启迪后人的。

  • 人教版高中语文必修2《亲近自然写景要抓住特征》教案2篇

    一、教学目标1.指导学生以一颗真挚的童心、爱心面对大自然,促使学生的心灵与大自然亲切交流。2.使学生明确写景文章的写作范围、写作重点、构思技巧。二、教学重难点明确话题,写景抓住特征,注重感情。三、教学方法多重对话法四、教学过程1.导入语:自然是人类生活的环境,是人类赖以生存的基础。人类不仅在物质上需要大地母亲的哺育,而且在精神上也需要向自然寻求依托。当知时节的春雨飘落大地时,当秋风吹来诱人的果香时,感到喜悦、幸福的决不仅是农民;过去的政治家、文学家,每当失意的时候,就会寄情山林;就是我们中学生,当不堪学习重负,感到身心疲惫的时候,去野外踏青,不也能愉悦身心吗?可以说人对自然的情怀是与生俱来的。但不同的人,对自然的感悟有深浅不同,情趣有高下之分。“万类霜天竞自由”的感悟,“大漠孤烟直”的审美不是人人都能有的。2.面对大自然,通过什么样的手段来促使我们的感悟、审美向高深方向发展呢?哪位同学说说。

  • 人教版高中语文必修2《想象世界学习虚构》教案2篇

    虚构不等于说假话。它是一种源于生活,但高于生活的艺术真实。我们可以举个例子:我国公认的最权威最真实的史书是——《史记》,那么,大家认为《史记》里有没有虚构呢?有。必修一的《鸿门宴》里就有虚构。大家想:司马迁是哪个朝代的人?西汉汉武帝时。刘邦项羽是哪个朝代的?秦末时期。那司马迁不可能坐时光穿梭机到秦末去参加鸿门宴吧?既然他没不在场,那课文《鸿门宴》里人物的语言、动作、甚至是表情从何而来呢?对,是司马迁根据有限的史料加以补充,想象、虚构出来的。那么,同学们在写作文时,也可以不必拘泥于亲身经历的事情,毕竟生活是平淡的,毕竟大家的生活阅历也有限,有时候,我们发挥想象、虚构一个故事来反映生活的真实,也许更生动、也更典型。所以,近年来高考试卷中都提示考生:作文可以大胆想象,编写故事。按照编故事的方式不同,我们的虚构性作文又可以写哪些类型呢:小说,散文,童话,寓言,科幻,故事新编……

  • 新人教版高中英语必修3Unit 1 Festivals and Celebrations-Listening &Speaking&Talking教学设计

    The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.
