部编人教版五年级上册《将相和》说课稿
鉴于《将相和》这篇课文的脉络和主题都很清晰，结合语文课程标准所提出的“课程目标应根据知识和能力、过程和方法、情感态度和价值观三个维度设计。”这一理论，我决定将本课的教学目标确定为：知识与能力：认识16个生字，会写12个字；理解课文主要内容。过程与方法：通过用小标题概括文中的三个小故事的方式，训练学生的概括能力并理解故事情节；通过师生间的交流与探索，帮助学生理清三个故事间的联系。情感态度价值观：学生通过将相之间由和到不和再到和的转变过程，感受人物形象，体会人物的爱国思想，品悟“和”在生活中的重要性，并以此为跳板，了解中国的“和”文化。教学的重点和难点放在引导学生充分感受文中的人物形象，并且体会到“和”的意义。
部编人教版五年级上册《白鹭》说课稿
一、说教材《白鹭》是人教版五年级上册第一单元的第一篇文章。这篇文质兼美的散文生动地描写了白鹭颜色、身段的精巧以及觅食、栖息、飞行时的韵味，给人以美的享受，表达了作者对白鹭的喜爱。全文条理清楚，主要写了白鹭的外形和活动之美，语言流畅而传神，营造出自然清新而又浓郁悠远的意韵。因此教学本文除了带领学生学会生字词并练习正确、流利地朗读课文外，更重要的是引导学生凭借具体的语言材料，体会“白鹭实在是一首诗，一首韵味无穷的诗”的内涵，从而感受白鹭的美，感受文章描绘的意境的美。二、说目标基于对教材的理解，结合本组课文的训练意图和学生的实际情况，我制定了以下教学目标。
部编人教版五年级上册《搭石》说课稿
一、说教材《搭石》这篇课文中，一幅幅生动的画面映入眼帘：秋凉在即，人们精心挑选平整方正的石头摆放在小溪中，几番精心踩踏；急着赶路的老人，发现搭石不稳，及时调整，满意才肯离去；一行人走搭石，动作协调有致，声音踏踏，清波漾漾，人影绰绰，充满了诗情画意；如果两个人同时过溪，招手礼让，闲话家常；若是谁偶遇老人，蹲身下伏，背负过溪……课文语言质朴，意境秀美，字里行间洋溢着浓郁的生活气息乡亲们无私奉献的精神和一心为他人着想的传统美德一定会强烈地感染着学生的心，激发他们善良的人性美，使他们充满为他人奉献的热望这也正是“搭石”于默默无闻中凸现出的精神
部编人教版五年级上册《太阳》说课稿
三、 说教法这是一篇说明文，它不是借助艺术形象传授知识的，而是在观察某些事物的基础上用准确、通俗的语言来说明事物传授知识的。所以我侧重以下几个方面来教的：1.抓住说明文的构段特点进行教学。教给学生学习方法，找出说明文在结构上注重一段一意，段首概括的规律，注重帮助学生理清文章的结构层次。2.抓住文中的语言，了解说明事物的方法。课文第一自然段为了讲清楚太阳的三个特点，运用了大量的数字来说明，给学生的感觉一目了然。但是为什么要引用传说，就是为了增加文章的生动性，这样教学既使学生了解了学法，又激发了学生学习兴趣。这样做的目的是，既教了课文，又学会了作者的写作方法。3.利用多媒体手段，激发学生的学习兴趣。说明文同记叙文相比，语言比较枯燥，形象性不强。在教学过程中，我制作了课件，变抽象为具体，激发学生主动学习的积极性，调动学生多种感官去接受知识，从而增强学习效果，是一举多得的方法。
部编人教版六年级上册《花之歌》说课稿
一、说教材： 《花之歌》是纪伯伦的散文诗集《泪与笑》中的一首，诗人用花的语言来叙述大自然的话语，文中尽显“纪伯伦风格”中的轻柔、凝练、隽秀与清新。诗人通过花语的倾心流露，构建了一幅大自然活生生的图画，图画中有诗意的浪漫，也有现实的真实，如：“我是诸元素之女:冬将我孕育，春使我开放，夏让我成长，秋令我昏昏睡去”写出了花的成长与芬芳。而“我是亲友之间交往的礼品，我是婚礼的冠冕，我是生者赠予死者最后的祭献”就袒露出了花的凋谢命运，都说纪伯伦的诗有着哲理，寓意深邃，从这就可以看出，诗人是用诗意的叙述和思考的敏锐来书写人生的。 二、说教学目标 1.知识目标： （1）理解、积累本课出现的重点词语。 （2）了解纪伯伦和其艺术风格。 （3）了解课文内容，领悟诗中拟人形象的情感内涵。
部编人教版五年级上册《 松鼠》说课稿
一、说教材 1.教材简析：本单元是说明文单元，我认为教材编者的目的是通过本单元的学习，让学生了解动物的外形、特点、习性，从而呼唤我们人类关注动物世界的生存状态，激发我们人类关爱动物、保护动物的热情。《松鼠》是法国作家、博物学家布封写的一篇科学小品文。科学小品文，它是说明文的一种，它与其他说明文不同之处，是采用某些文学的表现手法来说明事物。《松鼠》这篇课文作者就抓住了松鼠漂亮、生活习性的特点，采用拟人手法把松鼠写得活灵活现。所以这是一篇学生喜欢读的介绍小动物的文章。2.教学目标：鉴于以上分析，我把这课的教学目标定为：知识目标：1.认识生字。2.能用“先……再……然后”造句。能力目标：理解课文，能够有感情地朗读课文。情感目标：感受小动物的可爱，培养健康的生活情趣。
人教A版高中数学必修一充分条件与必要条件教学设计（2）
【例3】本例中“p是q的充分不必要条件”改为“p是q的必要不充分条件”，其他条件不变，试求m的取值范围．【答案】见解析【解析】由x2－8x－20≤0得－2≤x≤10，由x2－2x＋1－m2≤0(m>0)得1－m≤x≤1＋m(m>0)因为p是q的必要不充分条件，所以q?p，且p?/q.则{x|1－m≤x≤1＋m，m>0}?{x|－2≤x≤10}所以m>01－m≥－21＋m≤10，解得0<m≤3.即m的取值范围是(0,3]．解题技巧：（利用充分、必要、充分必要条件的关系求参数范围）(1)化简p、q两命题，(2)根据p与q的关系(充分、必要、充要条件)转化为集合间的关系，(3)利用集合间的关系建立不等关系，(4)求解参数范围．跟踪训练三3．已知P＝{x|a－4<x<a＋4}，Q＝{x|1<x<3}，“x∈P”是“x∈Q”的必要条件，求实数a的取值范围．【答案】见解析【解析】因为“x∈P”是x∈Q的必要条件，所以Q?P.所以a－4≤1a＋4≥3解得－1≤a≤5即a的取值范围是[－1,5]．五、课堂小结让学生总结本节课所学主要知识及解题技巧
人教A版高中数学必修一充分条件与必要条件教学设计（1）
本课是高中数学第一章第4节，充要条件是中学数学中最重要的数学概念之一， 它主要讨论了命题的条件与结论之间的逻辑关系,目的是为今后的数学学习特别是数学推理的学习打下基础。从学生学习的角度看，与旧教材相比，教学时间的前置，造成学生在学习充要条件这一概念时的知识储备不够丰富，逻辑思维能力的训练不够充分，这也为教师的教学带来一定的困难．“充要条件”这一节介绍了充分条件,必要条件和充要条件三个概念,由于这些概念比较抽象,中学生不易理解,用它们去解决具体问题则更为困难,因此”充要条件”的教学成为中学数学的难点之一,而必要条件的定义又是本节内容的难点.A.正确理解充分不必要条件、必要不充分条件、充要条件的概念；B.会判断命题的充分条件、必要条件、充要条件．C.通过学习，使学生明白对条件的判定应该归结为判断命题的真假.D.在观察和思考中，在解题和证明题中，培养学生思维能力的严密性品质．
人教A版高中数学必修一函数y=Asin(ωχ+φ)教学设计（1）
本节课选自《普通高中课程标准实验教科书数学必修1》5.6.2节 函数y=Asin(ωx+φ)的图象通过图象变换,揭示参数φ、ω、A变化时对函数图象的形状和位置的影响。通过引导学生对函数y＝sinx到y＝Asin(ωx+φ)的图象变换规律的探索,让学生体会到由简单到复杂、由特殊到一般的化归思想；并通过对周期变换、相位变换先后顺序调整后,将影响图象变换这一难点的突破,让学生学会抓住问题的主要矛盾来解决问题的基本思想方法;通过对参数φ、ω、A的分类讨论,让学生深刻认识图象变换与函数解析式变换的内在联系。通过图象变换和“五点”作图法,正确找出函数y＝sinx到y＝Asin(ωx+φ)的图象变换规律,这也是本节课的重点所在。提高学生的推理能力。让学生感受数形结合及转化的思想方法。发展学生数学直观、数学抽象、逻辑推理、数学建模的核心素养。
人教A版高中数学必修一全称量词与存在量词教学设计（2）
(4)“不论m取何实数,方程x2+2x-m=0都有实数根”是全称量词命题,其否定为“存在实数m0,使得方程x2+2x-m0=0没有实数根”,它是真命题.解题技巧：（含有一个量词的命题的否定方法）(1)一般地,写含有一个量词的命题的否定,首先要明确这个命题是全称量词命题还是存在量词命题,并找到其量词的位置及相应结论,然后把命题中的全称量词改成存在量词,存在量词改成全称量词,同时否定结论.(2)对于省略量词的命题,应先挖掘命题中隐含的量词,改写成含量词的完整形式,再依据规则来写出命题的否定.跟踪训练三3．写出下列命题的否定,并判断其真假:(1)p:?x∈R,x2-x+ ≥0;(2)q:所有的正方形都是矩形;(3)r:?x∈R,x2+3x+7≤0;(4)s:至少有一个实数x,使x3+1=0.【答案】见解析【解析】(1) p:?x∈R,x2-x+1/4<0.∵?x∈R,x2-x+1/4=(x"-" 1/2)^2≥0恒成立,∴ p是假命题.
人教A版高中数学必修一等式性质与不等式性质教学设计（2）
等式性质与不等式性质是高中数学的主要内容之一，在高中数学中占有重要地位，它是刻画现实世界中量与量之间关系的有效数学模型，在现实生活中有着广泛的应，有着重要的实际意义.同时等式性质与不等式性质也为学生以后顺利学习基本不等式起到重要的铺垫.课程目标1. 掌握等式性质与不等式性质以及推论，能够运用其解决简单的问题．2. 进一步掌握作差、作商、综合法等比较法比较实数的大小． 3. 通过教学培养学生合作交流的意识和大胆猜测、乐于探究的良好思维品质。数学学科素养1.数学抽象：不等式的基本性质；2.逻辑推理：不等式的证明；3.数学运算：比较多项式的大小及重要不等式的应用；4.数据分析：多项式的取值范围，许将单项式的范围之一求出，然后相加或相乘.（将减法转化为加法，将除法转化为乘法）；5.数学建模：运用类比的思想有等式的基本性质猜测不等式的基本性质。
空间向量基本定理教学设计人教A版高中数学选择性必修第一册
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.
倾斜角与斜率教学设计人教A版高中数学选择性必修第一册
(2)l的倾斜角为90°,即l平行于y轴,所以m+1=2m,得m=1.延伸探究1 本例条件不变,试求直线l的倾斜角为锐角时实数m的取值范围.解:由题意知(m"-" 1"-" 1)/(m+1"-" 2m)>0,解得1<m<2.延伸探究2 若将本例中的“N(2m,1)”改为“N(3m,2m)”,其他条件不变,结果如何?解:(1)由题意知(m"-" 1"-" 2m)/(m+1"-" 3m)=1,解得m=2.(2)由题意知m+1=3m,解得m=1/2.直线斜率的计算方法(1)判断两点的横坐标是否相等,若相等,则直线的斜率不存在.(2)若两点的横坐标不相等,则可以用斜率公式k=(y_2 "-" y_1)/(x_2 "-" x_1 )(其中x1≠x2)进行计算.金题典例 光线从点A(2,1)射到y轴上的点Q,经y轴反射后过点B(4,3),试求点Q的坐标及入射光线的斜率.解:(方法1)设Q(0,y),则由题意得kQA=-kQB.∵kQA=(1"-" y)/2,kQB=(3"-" y)/4,∴(1"-" y)/2=-(3"-" y)/4.解得y=5/3,即点Q的坐标为 0,5/3 ,∴k入=kQA=(1"-" y)/2=-1/3.(方法2)设Q(0,y),如图,点B(4,3)关于y轴的对称点为B'(-4,3), kAB'=(1"-" 3)/(2+4)=-1/3,由题意得,A、Q、B'三点共线.从而入射光线的斜率为kAQ=kAB'=-1/3.所以,有(1"-" y)/2=(1"-" 3)/(2+4),解得y=5/3,点Q的坐标为(0,5/3).

新人教版高中英语必修3Unit 5 The Value of Money-Reading and Thinking教学设计一
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
