    In this step, give students a few minutes to read the passage . While they are reading, I will write some key words of the text on the blackboard. Then ask students to retell the passage according to the key words.By retelling, students can improve their ability of language organization and have an overall understanding of the article.Step 4 Group discussionIn this step, students will be divided into groups of 4 to discussion the following question: What qualities make a great person?After their discussion, invite a few groups to make a report to the class.This group discussion can practice students’ oral English and cultivate their abilities of cooperation and communication.Step 5.

    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.

  • XX中小学生安全教育日国旗下讲话稿:安全在我心中

    XX中小学生安全教育日国旗下讲话稿:安全在我心中

    老师们、同学们:大家早上好!每年三月最后一周的星期一定为全国中小学生“安全教育日”。XX年安全教育日主题:强化安全意识,提升安全素养。今天我国旗下讲话的题目是《安全在我心中》。中外古今,多少文人墨客用优美的文笔唱出了对生命的歌颂。人们歌颂生命,是因为生命的宝贵,人们热爱生命,是因为生命的美好。然而,生命又是脆弱的。当生命遭到灾难或伤害时,它就会转眼消逝,那些鲜血写成的教训,使我们感悟到了生命的可贵,感悟到了安全的重要。据有关部门调查统计,全国每年约有1.6万名中小学生非正常死亡,平均每天有40多人。其中,交通事故已成为中小学生安全事故中的主要事故,食物中毒和意外伤害也一个个触目惊心、血泪交织的悲剧不能不叫人扼腕叹息、心有余悸,也更对我们敲响了安全的警钟。安全与我们每个师生密切相关,它关系到同学们是否健康成长,能否顺利完成学业。由于小学生年龄比较小,有时无法应对随时可能出现的各种危险,所以我们要加强教育,让学生远离危险,认识生活中的各种安全问题,学会正确处置意外,做好防范、树立起自我保护意识,提高自我保护的能力。

  • 小学数学人教版三年级下册《两位数乘两位数》整理与复习 说课稿

    小学数学人教版三年级下册《两位数乘两位数》整理与复习 说课稿

    单分析。一、说教材的地位和作用本节课的内容是人教版小学数学三年级下册第五单元的内容。在此之前,学生已经学习了两位数乘一位数笔算和两位数乘整十数的口算,估算和笔算。本节课学习的内容就是对以上知识点的梳理与巩固复习。二、说教学目标根据本教材的结构和内容分析,结合三年级学生的认知结构及其心理特征,我制定了以下的教学目标:1、通过复习,把“两位数乘两位数”这一单元的有关知识系统化、条理化。2、通过自主探索与合作学习,在系统复习的基础上理清知识脉络并进行分析归纳,掌握有序整理的方法,提高学习能力。3、经历独立整理、相互交流、综合应用的过程,感受学习的快乐。 三、说教学的重、难点本着《小学数学新课程标准》,在吃透教材基础上,我确定了以下的教学重点和难点。教学重点:用两位数乘两位数解决问题。 教学难点:笔算乘法积的定位。为了讲清教材的重、难点,使学生能够达到本节课设定的教学目标,我再从教法和学法上谈谈。

  • 小学数学人教版二年级下册《表内除法(二)——解决问题》说课稿

    小学数学人教版二年级下册《表内除法(二)——解决问题》说课稿

    一、教学内容本节课是九年义务教育六年制小学数学教科书(新人教版)二年级下册第42页的例3的内容。二、教材分析例3是用除法解决问题的内容,和“表内乘法(二)”中的解决问题相对应。这个题目中所涉及的数量已由离散量扩展到连续量,由实物个数扩展到了取自于量的数量,它所反映的数量关系是除法现实模型的拓展,渗透了单价、数量、总价的数量关系,需要学生根据除法的含义来解决。“想一想”是继续深化学生对除法意义的理解,并培养了学生发现问题,提出问题的能力。三、教学目标1、根据除法的意义,初步理解数量、单价、总价的数量关系,会用除法解决生活中与此数量有关的实际问题。2、将处罚扩展到连续量中去,深化学生对除法含义的理解。3、培养学生从具体生活情境中发现问题,根据问题筛选有用的信息从而培养解决问题的能力。

  • 小学数学人教版五年级上册《实际问题与方程 》说课稿

    小学数学人教版五年级上册《实际问题与方程 》说课稿

    2. 教材分析这节课的教学是学生在掌握行程问题基本数量关系的基础上进行的,本课教材给学生提供了“骑车”的情境,通过简单的路线图等方式呈现了速度路程等信息。然后要求学生根据这些信息去解决2个问题:①让学生根据两辆车的速度信息进行估计,在哪个地方相遇。②用方程解决相遇问题中求相遇时间的问题。3. 学情分析学生已经在三年级接触了简单的行程问题,四年级上册,学生就真正的开始学习速度、时间、路程之间的关系,并用三者的数量关系来解决行程问题。而本节课正是运用这些学生已有的知识基础和生活经验进行相遇问题的探究。4、教学目标从知识与技能、过程与方法、情感态度价值观的三维目标出发,制定了以下的目标:①使学生理解相遇问题的意义及特点。②经历解决问题的过程,提高收集信息、处理信息和建立模型的能力。③会分析简单实际问题中的数量关系,提高用方程解决简单的实际问题的能力。

  • 小学数学人教版一年级下册《20以内退位减法》说课稿

    小学数学人教版一年级下册《20以内退位减法》说课稿

    一、说教材(一) 教材内容分析1、地位作用本节内容在人教版小学数学一年级下册第二单元。本单元内容是在第一册集中教学20以内的进位加法的基础上,集中教学20以内的退位减法,“十几减9”是20以内退位减法教学的第一课时,第二课时是“十几减几”,它是在学生学习10以内加减法、20以内的进位加法的基础上进行的教学,它既是为学生学习退位减法铺路,也为学生学习四则计算奠定基础。2、教材分析20以内退位减法在本册尤为重要,对进一步学习多位数计算和其他数学知识非常重要,必须在理解算理的基础之上学会计算方法。在已学过的仅为加法和10以内的减法的基础上展开,巩固20以内的进位加法,进一步渗透加减法之间的互逆关系。让学生结合情境图解理解题意,进行计算等等,解决现实问题。引导学生从不同角度观察,通过操作后的讨论,用不同的思路思考,引出“想加算减”和“破十法”两种比较方便的计算方法。使学生在理解掌握“想加算减”的计算方法同时,还要理解“破十法”,并引导学生学会选择适合自己的计算方法,体现算法的多样化。

  • 小学数学人教版二年级下册《同级混合运算》说课稿

    小学数学人教版二年级下册《同级混合运算》说课稿

    一、说教材1.教材分析《同级混合运算》是九年义务教育人教版二年级下册第五单元的教学内容。教材创设了“图书阅览室”问题情境,目的是为了让学生了解脱式运算,了解没有括号的算式里,只有加减法或只有乘除法,都要从左往右按顺序计算。使他们树立学习数学的信心,逐步提高他们的计算能力。 2.教学目标知识目标:借助解决问题的过程让学生明白“在同级的混合运算中,应从左往右依次计算”的道理。能力目标:在经历探索和交流的过程中,理解并掌握同级运算的运算顺序,能正确运用运算顺序进行计算,并能正确进行脱式计算的书写。情感目标:培养学生养成先看运算顺序,再进行计算的良好习惯,同时提高学生的计算能力。3.教学重难点教学重点:理解并掌握同级运算的运算顺序,并能正确地进行脱式计算。教学难点:能正确进行脱式计算,掌握脱式计算的书写格式。二、说教法根据新课程理念,学生已有的知识、生活经验,结合教材的特点,我采用了以下教法:1、情景教学法:新课开始,让学生通过图书馆这一情景,理解运算顺序。2、发现、讨论法:利用我们小组合作座位优势,让小组间讨论、说计算过程,从而掌握计算方法。三、说学法运用书本为载体,以观察、比较、小组讨论、推理和应用及口算为主线,目的是为了使学生对学习有兴趣和留给学生学习思考的空间。

  • 小学数学人教版二年级下册《数据收集整理》说课稿

    小学数学人教版二年级下册《数据收集整理》说课稿

    2、教材分析本单元是在学生已经学习了比较、分类等知识的基础上学习统计的基本知识。为了让学生能了解学习统计的必要性,教材选择了与学生生活有密切联系的生活情景,通过参与有趣的调查活动,使学生经历收集信息、处理信息的过程,了解调查的方法,学习收集、整理、描述和分析数据,认识统计的意义和作用。本单元学生学习的内容主要是调查、记录和整理结果,意在使学生体会抽样调查的合理性和记录方法的多样性。学会用画“正字”法记录数据,使结果易于整理。3、学情分析学生已经学习了比较、分类等与统计相关的初步知识,为本单元进一步学习调查、记录和整理,简单分析数据奠定了基础。在日常生活中有许多与统计相关的生活场景,只是学生没有发现,需要教师在课堂上引导学生研究和体会:“生活中处处有数学”“数学来源于生活”。4、教学重点本着2011年版数学课程标准,在充分研究了新教材的基础上,我把这节课教学重点确定为让学生掌握如何收集数据并整理数据,同时能够进行简单的分析。
