    人教部编版七年级语文上册热爱生活,热爱写作教案

    三、实战演练1.明确题干要求师:阅读教材P18的写作实践三,读读题干和“提示”,然后集中讨论一下,你是如何理解这个写作实践暗含的要求的。预设(1)这个题目可以简单概括为成长中的事件,范围比较宽广,类似于经常碰到的《难忘的一件事》一类的作文题。(2)一定要注意“成长”这个关键词,在描述这个事件时,一定要写出自己人生体悟的变化。(3)要选择一件有意义的、使“我”成长的事来写,在文末还应升华主题,写出自己在经历这件事后得到的人生启示。2.补充写作提示师:为了帮助大家完成好这次习作,老师在教材的基础上,还另外补充了三条“提示”。课件出示:提示:1.选材要小。选取生活中的一两个片段来刻画人物、表达感情。从小事入手,于细微处见精神,以小见大,突出“难忘”“印象深刻”。2.叙事要详略得当。叙事要围绕中心,抓住重点,把最能体现事件意义、最能展示人物形象的言行、心理描写得真实而详细。同时,要讲究剪裁,选取典型的、能揭示事物本质的、有说服力的材料表达中心思想,做到详略得当,主次分明。

    【设计意图】本环节是为了突破难点而设计,以名篇佳作为范例,引导学生理解什么叫作合理而大胆的想象,示范作用明显。另外,本环节也是为下一环节——学生自由想象自己十年后的生活做铺垫。三、写作实践师:同学们,让我们拿起笔,徜徉于联想和想象的世界。1.学生写作课件出示:题目:你有没有憧憬过未来的生活?你觉得,十年以后的你是什么样子的呢?在做什么?又有着怎样的精神面貌呢?请以《十年后的我》为题,发挥想象,写一篇作文。不少于500字。思路点拨:发挥大胆而丰富的想象,可从十年后的生活变化、社会发展变化等方面着手,塑造人物的变化,如人物的相貌、心态及性格等,但性格的发展一定要符合逻辑。写法指导:选择一件事或几件事,通过语言、动作等描写来展现人物的性格。写作中也可采用前后对比的手法,如现在的“我”性格暴躁,十年后的“我”性格温顺等,通过人物的变化来反映社会的变化。

  • 人教版新课标小学数学一年级下册两位数加一位数和整十数 说课稿

    人教版新课标小学数学一年级下册两位数加一位数和整十数 说课稿

    教材分析:本课内容是人教版一年级下册第六单元的第二课时“两位数加一位数和整十数”中的内容,包括两位数加一位数(不进位)、两位数加整十数;两位数加一位数(进位)。有两个例题,共用3节课完成。本节课是第一节,主要让学生理解算理,掌握算法。教材把加一位数与整十数对比集中编排,其目的是让学生加深对相同单位的数才能直接加减的算理认识,为后面学习两位数加减两位数打基础。教材的设计遵循了从具体到抽象的原则。先让学生在计算问题的情境中,动手操作、动脑想、讨论交流探讨不同的计算方法,再让学生运用获得的方法进行口算,体现了知识的形成过程,有利于培养学生抽象思维能力。练习设计注意专项与综合训练相结合,注意变换形式,突出正确率。这些都是我们教学中值得借鉴的。

    2,解决三个圆片能摆出的数。小精灵聪聪也给大家提问题了:(课件出示:你能用三个圆片表示不同的数吗?)你们回答他,能不能?(1)现在请小朋友们自己动手摆一摆,并且不自己摆出来的数写在老师发给你们的纸上,看谁摆的又快又对。(2)汇报结果:你摆了几个数?分别是什么?是怎么摆的 ?这个活动的设计是为了培养学生的动手操作能力,提高学生学习数学的热情。利用自己总结出来的方法来进行操作,让学生体会到成就感。通过学生的汇报,培养学生的语言表达能力,让学生的手,脑,口的能力同时得到了锻炼。3,小朋友们真棒,现在我们不摆圆片,你能不能在脑子里想着摆圆片的方法,在纸上写出四个圆片都能表示那些数字呢 ?这个活动的设计,是让学生从操作走向有序的思维,让学生有条理的思考问题,将数学抽象化。

    大班数学《二次分类》说课稿

    人是一个能动的个体,学习是学习者主动建构的过程。社会的发展也强烈需要发展幼儿的主动性和创造性。而数学是一门抽象性、逻辑性很强的学科。在我选择的“二次分类”这个数学活动时,我是考虑到,老师们习惯于仅以幼儿认识事物是从具体到抽象这一特点为依据,只强调直观性,在活动中教师常运用教具演示,并以此为基础讲解基本的数学概念,而实际上,幼儿数学概念的形成不是通过听老师讲、看老师演示所能解决得了的,必须通过幼儿自己主动活动的过程。“图形的二次分类”我希望提供给幼儿充分的操作材料,再加以引导,一步一步深入,使幼儿真正在操作过程中去发现、归纳“图形的二次分类”的特征。

    广场为开放式,从四面都可进入,但在东北和西南各有一个木制长廊,上面缠络着紫藤萝,每到夜晚,这里点亮一盏盏小彩灯,与紫藤萝相辉映,煞是好看。广场正北对着的是公园管理处,共2层。南面是万福园芙蓉广场富强店,面积有4000多平方米,是一个超大型的商场。这就是我们的芙蓉广场,怎么样,很漂亮吧,有空来玩玩吧!生点评:何秀同学写芙蓉广场采用“总—分—总”的结构,开篇先点明广场的位置、特征,然后介绍得名原因、广场的规模地势,再按照游踪介绍,最后总结。全文采用多种说明方法,且融入情感,既让读者了解了芙蓉广场的有关知识,又表达了自己的喜爱之情。师点评:文章介绍群体建筑——广场,抓住芙蓉广场秀美、雅致的特点,重点介绍第一层主题广场,略写周边草坪及建筑,详略得当,层次分明。另外,作品采用“总—分—总”的结构,以游览的方式引导读者了解广场建筑,让文章生动亲切,也是作品的亮点。

    水的性质水是液体。石块和木块有一定的形状,无论放在桌子上或者盒子里,它们都不会改变自己的形状,都是固体。水就不同,放在圆杯子里就成为圆形,放在方盒子里就成了方形,它没有一定的形状。水是无色透明的。有人说水是白色的,这话错了。拿水同牛奶比较一下就会明白,牛奶才是白色的,水是什么颜色也没有的。如果把一根筷子插入牛奶里,我们就看不见它。而把一根筷子插入清水中,我们能够透过清水看见插入的筷子。水是无嗅、无味的。怎样来区分无色透明的烧酒和水呢?光凭肉眼是毫无办法的。只要闻一闻,尝一尝就能正确无误地区分了。烧酒有酒的气味和味道,而水却什么气味、什么味道也没有。因此,在正常的情况下,水是无色、无嗅、无味的液体。

    读数时,先读十位上的数,再读个位上的数,十位上是几就读几十,个位是几就写读几,这个数读作“二十四”。设计意图:(由用小棒表示数过渡到用计数器上的珠子来表示,使学生初步理解数位的意义,会利用计数器正确读数、写数。)(4)教师出示4捆和2根小棒(即42根小棒),用同样的方法完成以上过程。当学生写出并读出42以后,让学生对比24与42中的“4”、“2”的意义,加深对不同数位上的数所表示的意义的理解。(设计意图:通过42与24的对比,加深对不同数位上的数所表示的意义的理解。)2.教学例5(1)第一行3题让学生独立完成,读给同桌的同学听,最后集体订正。(2)第二行第1题教师引导学生观察,十位上有4颗珠子,个位上一个也没有,试问:这个数该怎么写呢?学生回答后,教师板书“40”,并强调“当个位上一个也没有时,要用0占位”。

    2、教材分析整十数加、减整十数的计算是在10以内加、减法的基础上进行的,只是计数单位不同,这里以十为计数单位。教学内容的编排,分三个层次:一、以实际情景——花卉展提供计算题,并呈现算法的多样化;二、让学生动手操作(如摆小棒)理解算理、掌握算法;三、脱离直观手段,让学生思考算法。通过让学生在生动具体的情境中学习计算,引导学生独立思考与合作交流多种不同的算法,进一步培养计算能力。这样安排,有助于学生加深对相同单位的数可以直接相加、减的认识,为后面学习任意两个数相加、减打基础。整十数加、减整十数属于计算教学中的重点内容之一,应给予足够的重视。教材的编排是由直观操作等依靠实物思考到脱离实物思考,遵循由具体到抽象的原则,有利于学生抽象思维的培养,为进一步提高计算速度、培养计算能力,解决实际问题打基础。

    一、说教材分析教材分析:本部分内容是在学生认识了认数的第一阶段—20以内各数认识的基础上,扩展到认数的第二阶段—100以内各数的认识。本阶段的数概念不仅是学习100以内数计算的基础,也是认识更大的自然数的基础。它在日常生活中有着广泛的应用,因此必须使学生切实学好。在分析教材的基础上,灵活的运用教材,我认为开始的主题图,如果10只一群地出示,虽然有利于学生估数,但这样学生能很快地10只10只地数出羊群只数是100,在后面数100个物体的个数时,就会受其影响而10个10个地数,这样的数法,要在学生会逐个数数的基础上自然生成,其实,它比一个一个地数要高一个层次,数数单位由“一”变成了“十”,不利于学生把100以内的数逐个数出来,因此,我把主题图的出示放在了一个一个数物体之后。

    1. First, ... then, ... next, ... finally, ...首先,……然后,……接着,……最后,……这是英语中表达做某事的步骤的一种说法。如果步骤较多,还可以说:first-next-after that-later on-finally/at last通常你会听到说英语国家的人在说 first, next, then, finally 和后面的内容时,他们会做一些停顿。这样就能提前告诉听者接下来讲的是一系列的步骤。这一点在朗读和听力中应特别注意。2. how many, how much均为疑问词,同是“多少”,但用法不同。请看:how many修饰可数名词复数,how much修饰不可数名词。但在用法上,同学们常犯如下错误:1) [误] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容词,常修饰名词作定语,故后面跟名词。2) [误]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修饰不可数名词时,谓语动词用单数。how many与how much的区别可简记为:前how many:问“多少”,复数名词后面跑;how much问“多少”,不可数名词单数好。前者答语用基数词,后者答语用数量关系。

    “Go for it!” is based on “Task-Based Language Teaching”. It adheres to “The authenticity principle”, “The form-function principle”, “The task dependency principle” and “The principle of learning by doing”. These principles all accord with the demands of curriculum focus.In and of Grade Seven (II), “Go for it!”, students have learned “The Simple Past Tense”. And it appears again in of Grade Eight (I). teaches students more about how to talk about events in the past. In addition, it gives affirmative and negative statements in the past tense, such as the sentence patterns “Did you see …?” “Were there …?” “Did you go …?” As the first part of Unit 8, Section A opens with a picture presenting the last school trip in the aquarium and continues with several step-by-step practice activities, which are all good for students to master “The Simple Past Tense”. Doing well in Section A will help students integrate the new target language with that in Section B. Thus, they can describe the events in the past freely and foster their own ability of reflecting and practicing. II. Teaching ObjectivesTeaching objective is the beginning and aim of teaching activities. According to the overall goal of the English elementary course--- improve students' synthetic ability of language application, which should be based on the development of students’ “Language knowledge”, “Language skills”, “Character building”, “Learning strategies” and “Cross-cultural awareness”. The teaching objectives are described as follows(I). Knowledge objectivesi. Master the simple past tense of regular and irregular verbsii.
