3、拓展延伸,启迪心智,创设课堂训练营。三、说学法1、纸上得来终觉浅,圈点、勾画、批注法,学好文言基本功。2、自主合作加探究,眼耳口脑手并用,破疑解难在其中。四、说课时安排《鸿门宴》篇幅较长,文言知识较丰富,文章内涵丰厚,因此我设计用五课时教学本文。第一课时:了解作家作品,积累文言知识,感受作者隐忍发愤的著书精神(初读)第二课时:理清故事情节,概括人物形象,学习客观地评论历史人物,(熟读)第三课时:进一步梳理文言知识,精读课文,要求读透。(精读)第四课时:通过对人物、事件的赏析,加深学生对人物的理解,锻炼学生的开放性思维,由学生自主认识到人物的性格,悲剧的原因等问题。(赏读)第五课时:补充课本教学内容:同学生一起阅读古今关于刘邦项羽的一些篇章:让学生投入进来,把握自己眼中的项羽。(展读)在文言文学习的过程中,采取五步学习法:初读-熟读-精读-赏读-展读(板书)
一.教材理解教材地位与作用:本单元“阅读与鉴赏”部分,本单元要求学生能在了解诗歌创作的时代背景的情况下通过反复诵读诗歌,把握其中丰富的意象,领悟诗歌独特的意境和诗人所要表达的情感。《雨巷》是现代派大师戴望舒的成名作和前期的代表作,他曾因此而赢得了“雨巷诗人”的雅号。本单元以《雨巷》为例子给学生展示了象征主义诗歌的特点,《雨巷》运用了象征性的抒情手法。诗中那狭窄阴沉的雨巷,在雨巷中徘徊的独行者,以及那个像丁香一样结着愁怨的姑娘,都是象征性的意象。这些意象又共同构成了一种象征性的意境,含蓄地暗示出作者即迷惘感伤又有期待的情怀,并给人一种朦胧而又幽深的美感。富于音乐性是《雨巷》的另一个突出的艺术特色。诗中运用了复沓、叠句、重唱等手法,造成了回环往复的旋律和宛转悦耳的乐感。因此我把本课的教学重点和难点确定为:教学重点:通过反复诵读,领略诗歌的音乐美以及分析其成因教学难点:分析意象以及其象征意义初步掌握鉴赏诗歌的方法
请一位朗诵水平较好的学生,有感情的朗读课文12自然段,其他同学完成一项任务:这一段可否去掉?为什么?学生思考、圈画、交流、讨论,然后小组发言,其他小组补充,教师从旁予以点拨,引导学生进一步明确作者的思想情感。明确:作者要创造一种文化氛围,于自然气息之外再添一重文化气息,与“故都”题旨暗合。从行文章法上看,这里是宕开文笔,纵横议论,显出深厚的文化底蕴和开阔的思路。这一段采用议论,通过古今中外的引证,说明感秋处处有,中国文人最突出,而秋“深味”非在中国北方莫属,这其实还是为了突出故都之秋。(设计意图:提高学生探究的能力,充分把握本文的教学内容,深刻体悟作者的情感,了解作者对秋的礼赞情感,从而突破教学难点。)
学法指导:高一学生对文言文阅读已具备了一些基础知识和积累,但对如何学习文言文,还是一个新课题,因此教师应引导学生掌握学习方法,运用已有的知识框架同化新信息,建立新的智能,逐步走向独立学习的境界。一、引导学生利用课文注释,使用工具书自己翻译,必要时教师进行点拨、解难,培养自学能力。二、告诉学生翻译文言文要遵循的原则。三、调动学生思考、讨论、交流的积极性,教师适时点拨,培养学生发现问题、解决问题的能力。四、提示学生反复诵读课文,体会文章所阐述的道理。五、鼓励学生及时归纳学习文言文的方法,注意积累文言文知识。教学程序:教学本课可安排2课时。第一课时:1、导入新课:首先给学生介绍毛泽东的七绝诗《为李进同志题所摄庐山仙人洞照》:“暮色苍茫看劲松,乱云飞渡仍从容。天生一个仙人洞,无限风光在险峰。”学生通过诵读领会了“无限风光在险峰”一句的含义。随后因势利导,引出课题,指出今天我们要学习的王安石的《游褒禅山记》,就含有类似的深邃哲理。
一. 教材分析1. 本单元的中心话题是“计算机(Computers)”,内容涉及计算机的发展历史,计算机的应用等。本节课是该单元的第一课时,我将Warming up, Pre-reading and Comprehending这四部分整合为一节精读课。其中。Reading部分是题为WHO AM I?的文章,以第一人称的拟人手法介绍了计算机发长演变的历史和计算机在各个领域的应用,其主旨是表达计算机的发展变化之快以及在生活中用途之广。而Warming up部分以图片的形式展现了计算机的发展历程;Pre-reading中的问题和排序分别是为了预测语篇的内容和测试学生对计算机历史了解的情况;Comprehending则通过各项练习训练学生的阅读技能,从而加深对文章的理解。可见这几部分是一个有机的整体。2. 教学目标:1) 语言目标:重点词汇及短语:abacus, calculate, calculator, PC, laptop, PDA, robot, analytical, technological, universal, mathematical, artificial, intelligent, network, explore, in common, as a result.重点句子:a. My real father was Alan Turing, who in 1963 wrote a book to describe how computers could be made to work, and build a “universal machine” to solve any mathematical problem.
When it comes to the students’ studying methods, I'd like to introduce my Ss first. The Ss have a good command of basic language points. They’re interested in learning English, and they take an active part in English class, so they will have fun in autonomous, cooperative and inquiry learning. I will just serve as a guide, showing them the way to explore how to make more progress in their English learning.Now it’s time for the most important stage of this lesson. My teaching procedures are arranged as follows:Step1.Leading-in (3 minute)Play a video of a wide variety of wildlife to introduce my topic. Step2. Speaking (12 minutes)We will use our textbook Page25. Let the Ss fast read the short paragraph to warm up. Ask them to talk about the report on some endangered wildlife in China with the dialogue patterns on the screen. Lastly, I will invite some groups to demonstrate their dialogues about saving wildlife in China.Step3.English play (3 minutes)Watch another video in praise of their excellent performance just now. It’s about Jack Chen’s(成龙)and Yang Ziqiong’s wildlife protection.Step4. Listening (twice 13 minutes)This time, I’ll ask the Ss to fill in the blanks of the monologue of the 2 movie stars above. Step5.Discussion (3 minutes)Which would you like to choose to wear, clothes made of cotton, artificial leather or animal skins? Why ?Step6. Summary (3 minutes)1. If there were no wildlife, there wouldn’t exist human beings. If the buying stops, the killing can, too.2. Animals are our friends. To love animals is to love ourselves. Stop hunting, killing and destroying wildlife.3. Let’s live in harmony with all the living things in the world. Step7. Music appreciation (3 minutes)Let the Ss appreciate the song Earth Song by Michael Jackson. Last but not the least, I will show you my blackboard design.
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

(三)教学重、难点1、教学重点:结合课文,了解演讲辞针对性强、条理清楚、通俗易懂、适当的感情色彩等特点。2、教学难点:深入理解文章内涵,联系现实,体会本文的现实意义二、说学情高中学生在初中阶段已经接触过演讲辞了,对演讲词的特点已经有了一些基本的知识,因此本轮的教学应该让他们在此基础上有所提高。本文是学生在高中阶段第一次接触演讲辞,有必要让他们了解演讲辞的特点及课文如何体现这些特点的。随着年龄的增长,生活阅历的增加,高中学生正逐渐形成自己对世界、对人生的看法,蔡元培先生的这篇文章能很好地激发他们对当前的高中学习和未来的大学生活进行思考。此外,学生对北大的历史及蔡元培先生作这番演讲的时代背景了解不深,应作出补充说明。
得到13-8=这个算式后,我让小朋友们想办法,“13-8怎么算?你是怎样想的?把你的想法告诉你小组的同学们。”由于我是用讲故事的形式引出这一问题的,因此在计算13-8时,小朋友们就被迫要自己想办法去计算,而不能光借助情境图去直接数出得数。这并不阻碍算法的多样化,相反更好地实现了算法多样化的目的,真正让学生成为了数学学习的主人。为了增加这堂课的趣味性,我有意将学生说出来的各种算法分别以他们的名字来命名,这样一来,学生兴趣盎然,都积极投入到了寻找算法的思考活动中来了。在寻求多样化的过程中,充分发挥了学生学习的主体性,培养了学生的创新精神,让每一个学生都能体验学习的成功。学生们在思考、讨论中可能会出现这样几种算法:
一.创设情境,解决问题。(一)直观认识1.请每个同学举起手中的毛线。说说你的毛线和其他同学有什么不一样。(学生会观察到有长短,颜色,粗细的不一样。)设计这个环节是为了让学生先找出线段的非本质特征。只有去掉了非本质特征,学生才能更明确到记住线段的本质特征。)2.请每个同学在认真观察,说说你的毛线和其他同学的有什么是一样的。这个环节学生最基本能发现手中的毛线是直的。(二).讲解概念1.通过直观的认识后,由教师讲解线段这个概念:像我们刚才手中这一条直直的毛线,就可以看做是线段。(这句话的讲解中,教师要突出直直的,这是线段的最基本特征,还有一个词是是看做是,数学的是严谨的,不能说这条毛线是线段,并让学生也举起毛线和老师一起说说这句话。)
前后是一年级下册第1单元位置中的内容,包括了上下、前后、左右、位置的知识。《数学课程标准》要求老师应该充分利用学生已有的生活经验,随时引导学生将所学的数学知识应用到生活中去,解决身边的数学问题,了解数学在现实生活中的作用,体会学习数学的重要性。对于这一内容的学习,学生有丰富的生活经验积累,在教学中想努力激活学生的相关经验,安排了让学生在多个实践活动观察、操作、想像、思考、游戏、说说等活动中体验前后顺序。考虑到一年级小朋友的年龄特点,我对教材作了比较大的调整,利用跟着笑笑去动物园看运动会把各个教学环节各项活动串联起来,使小朋友在体验探索前后的知识时有更大的动力和积极性,同时,采用漂亮的画面和动物来增强小朋友的兴趣好奇心和探索的积极性。
我说的第二个内容是:比较大小。这节内容的编写意图是先让学生利用实物的多少比较相应数的大小,在利用计数器比较所表示数的大小,接着在直接比较数的大小。以上过程体现了儿童从具体到抽象的认知特点,便于学生掌握比较两个数大小的一般方法。另外,教材提供了充分的并且贴近学生生活实际的教学资源,我们应尽量利用好它,并积极地动手制作学具,以便提高教学效果。以下是教学流程及说明。第一大环节出示例8鸡蛋图,观察比较。这幅图的情景非常贴近农村孩子的生活,学生一看就会感到很亲切,教师可以用兴奋的语言介绍画面,使画面生动起来,同时也明确了学习任务,比如可以这样说:“明明家养了两只母鸡,小鸡下蛋了,明明真高兴,他每天都帮着妈妈捡鸡蛋,而且明明是个细心的孩子,他把两只鸡下的蛋放在各自的盘里,让两只鸡比比赛,看谁下得蛋多。小朋友,你们知道哪只鸡下的蛋多吗?我们快来数一数吧!
二、说教法从教学内容来看,统计教学以探究研讨法为主。如设计中进行下个月进货的决策时,对已有的销售数据进行统计学上的分析外,其结果能对下一步的科学决策提供依据,体现统计在实际生活中的作用。从教学对象来看,小学中年级多用引导发现法、尝试教学法。随着年龄的增长,学生对社会问题也会越来越好奇和关心,因此素材的选择加强了联系社会生活实际,如设计垃圾调查与研究等题材,潜移默化地对学生进行保护环境等社会问题任何一节数学课都是多种教学方法的综合运用,如谈话法、讲解法等的有机结合!三、说学法在教学互动过程中,引导学生探索、、交流、观察、猜测、归纳等方法,培养学生的观察能力、分析能力及合作能力。因为是统计课,课前要去收集、整理实例,为课内互相交流积累素材。四、说教学过程(一)情境创设,复习旧知学校要购买一批体育器材,现在要调查同学们对体育运动的爱好。出示402班学生的纵向单式统计图情况。之后收集、整理、绘制本班学生的统计情况。
① 实验设计将学生分组,利用桌上的器材进行探究(幻灯片展示)这个实验难度较大,为了降低难度,为实验探究铺下第二台阶,要求学生先分小组讨论以下问题(幻灯片展示)有些学生可能不知如何下手,我会要求学生先阅读课本中的实验描述从中得到一点提示,再让一两个小组同学回答,这样既体现了学生学习的主体性又可提高学生自主思考和语言表达能力,之后我再进行补充完善(幻灯片展示答案),并用幻灯片把实验步骤展示出来,在学生实验过程一直保留,使学生能朝正确的方向进行猜想和操作,为实验探究铺下第三个台阶。② 实施探究在学生分组进行探究过程,教师巡视解惑,随时观察学生情况,解答学生提出的问题,还可用自言自语方式提示应注意的一些问题,如仪器的正确使用,操作的规范等,帮助学生尽量在规定时间内顺利完成实验。
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。
统计是一种数学思想,也是认识客观事物常用的一种方法。让学生学习统计,要引导他们经历收集、整理数据的过程,精力把整理出来的数据用图表形式表现出来的过程,经历对统计的数据进行分析、判断的过程,从中理解并掌握一些有关统计的基础知识和基本技能,学习解决实际问题。(一)新的课程标准要求我们的数学课程应体现基础性、普及性和发展性。要强调从学生已有的生活经验出发,要使学生学有价值的数学,这些内容要有利于学生主动地进行观察、实验、猜测、验证、理解与交流等数学活动。(二)本课的教学通过学生积极参与数学活动,合作交流,力求体现人人学有价值的数学,体现数学就在我们的身边,与我们的学习生活紧密相联,体会统计的目的和意义,掌握统计的方法,体验数学学习的乐趣。
三、制作统计图教师:事先我们一起搜集了这几年中我们班同学家庭拥有计算机的情况,并制成了统计表,请谁来介绍一下。(学生利用事先制成的统计表介绍数据)如果请你将它制作一份折线统计图,你有信心完成吗?小组讨论:你认为在制图时应做哪些工作?有什么注意点?(学生小组讨论后交流)在交流中,教师顺应学生回答,并相应介绍折线统计图各部分名称:(1)横轴:一般用于标明日期的前后;(2)纵轴:标明数据,反映单位长度表示的数据大小,一般最高数据比统计到的最高数据稍高一些;(3)制表日期和单位。学生独立在练习之上尝试练习。教师指名演示,同学互相评价并改正。统计分析:从这张统计图上你可以获得哪些信息?学生相互交流,也可以提问请同学回答。
第三板块:夯实基础 发展技能检测是实施课堂优化教学的重要手段。因此,本节课的第三板块我设计了课堂目标检测,检测中以闯关形式设计了五个活动:即第一关:快乐填一填。第二关:动手剪一剪。第三关:用心拼一拼。第四关:仔细数一数。第五关:神奇拼一拼。检测中前三关,重抓基础知识的落实,后两关注重学生技能的培养,以及用数学的能力,符合低年级儿童年龄特点,我充分利用了学生争强好胜,乐于竞争的心理,以争夺智慧星的小组合作赛形式进行检测。既提升了学生自主强化知识的兴趣,又培养了学生集体主义观念。以上是我对《平面图形的拼组》一课设计理念的剖析与阐述,当然,教学是一门缺憾的艺术。所以,不足之处还请各位前辈提出宝贵意见!谢谢大家!
