一.教材理解教材地位與作用:本單元“閱讀與鑒賞”部分,本單元要求學(xué)生能在了解詩歌創(chuàng)作的時代背景的情況下通過反復(fù)誦讀詩歌,把握其中豐富的意象,領(lǐng)悟詩歌獨(dú)特的意境和詩人所要表達(dá)的情感?!队晗铩肥乾F(xiàn)代派大師戴望舒的成名作和前期的代表作,他曾因此而贏得了“雨巷詩人”的雅號。本單元以《雨巷》為例子給學(xué)生展示了象征主義詩歌的特點(diǎn),《雨巷》運(yùn)用了象征性的抒情手法。詩中那狹窄陰沉的雨巷,在雨巷中徘徊的獨(dú)行者,以及那個像丁香一樣結(jié)著愁怨的姑娘,都是象征性的意象。這些意象又共同構(gòu)成了一種象征性的意境,含蓄地暗示出作者即迷惘感傷又有期待的情懷,并給人一種朦朧而又幽深的美感。富于音樂性是《雨巷》的另一個突出的藝術(shù)特色。詩中運(yùn)用了復(fù)沓、疊句、重唱等手法,造成了回環(huán)往復(fù)的旋律和宛轉(zhuǎn)悅耳的樂感。因此我把本課的教學(xué)重點(diǎn)和難點(diǎn)確定為:教學(xué)重點(diǎn):通過反復(fù)誦讀,領(lǐng)略詩歌的音樂美以及分析其成因教學(xué)難點(diǎn):分析意象以及其象征意義初步掌握鑒賞詩歌的方法
[教學(xué)反思]人教版高中語文必修二第三單元安排了《蘭亭集序》《赤壁賦》《游褒禪山記》三篇古代山水游記散文,它們借游賞之事,探索生命的意義、治學(xué)的道理。師者,所以傳道、授業(yè)、解惑也。高中的教材選用的都是歷史經(jīng)典名篇,每一篇都閃爍著儒道釋等百家光輝的思想。編者要老師傳道的意圖很明顯。即非如此,看著這些影響歷代、影響世界的如日月之耀眼光華的偉大思想就躺在我們的教科書里,又如何能不講呢?所以,我將本課的教學(xué)重難點(diǎn)擬定為:幫助學(xué)生建立積極的生死觀,掌握多角度看問題的正確的思想方法。當(dāng)然,也讓學(xué)生領(lǐng)會了融寫景、抒情、說理于一爐的大家手法。整堂課各教學(xué)環(huán)節(jié),環(huán)環(huán)相扣,過渡自然,讀、思、議、寫訓(xùn)練到位,而且全部圍繞“生死觀”展開,如一篇形散神不散的散文。
學(xué)法指導(dǎo):高一學(xué)生對文言文閱讀已具備了一些基礎(chǔ)知識和積累,但對如何學(xué)習(xí)文言文,還是一個新課題,因此教師應(yīng)引導(dǎo)學(xué)生掌握學(xué)習(xí)方法,運(yùn)用已有的知識框架同化新信息,建立新的智能,逐步走向獨(dú)立學(xué)習(xí)的境界。一、引導(dǎo)學(xué)生利用課文注釋,使用工具書自己翻譯,必要時教師進(jìn)行點(diǎn)撥、解難,培養(yǎng)自學(xué)能力。二、告訴學(xué)生翻譯文言文要遵循的原則。三、調(diào)動學(xué)生思考、討論、交流的積極性,教師適時點(diǎn)撥,培養(yǎng)學(xué)生發(fā)現(xiàn)問題、解決問題的能力。四、提示學(xué)生反復(fù)誦讀課文,體會文章所闡述的道理。五、鼓勵學(xué)生及時歸納學(xué)習(xí)文言文的方法,注意積累文言文知識。教學(xué)程序:教學(xué)本課可安排2課時。第一課時:1、導(dǎo)入新課:首先給學(xué)生介紹毛澤東的七絕詩《為李進(jìn)同志題所攝廬山仙人洞照》:“暮色蒼??磩潘桑瑏y云飛渡仍從容。天生一個仙人洞,無限風(fēng)光在險峰?!睂W(xué)生通過誦讀領(lǐng)會了“無限風(fēng)光在險峰”一句的含義。隨后因勢利導(dǎo),引出課題,指出今天我們要學(xué)習(xí)的王安石的《游褒禪山記》,就含有類似的深邃哲理。
一. 教材分析1. 本單元的中心話題是“計算機(jī)(Computers)”,內(nèi)容涉及計算機(jī)的發(fā)展歷史,計算機(jī)的應(yīng)用等。本節(jié)課是該單元的第一課時,我將Warming up, Pre-reading and Comprehending這四部分整合為一節(jié)精讀課。其中。Reading部分是題為WHO AM I?的文章,以第一人稱的擬人手法介紹了計算機(jī)發(fā)長演變的歷史和計算機(jī)在各個領(lǐng)域的應(yīng)用,其主旨是表達(dá)計算機(jī)的發(fā)展變化之快以及在生活中用途之廣。而Warming up部分以圖片的形式展現(xiàn)了計算機(jī)的發(fā)展歷程;Pre-reading中的問題和排序分別是為了預(yù)測語篇的內(nèi)容和測試學(xué)生對計算機(jī)歷史了解的情況;Comprehending則通過各項練習(xí)訓(xùn)練學(xué)生的閱讀技能,從而加深對文章的理解。可見這幾部分是一個有機(jī)的整體。2. 教學(xué)目標(biāo):1) 語言目標(biāo):重點(diǎn)詞匯及短語:abacus, calculate, calculator, PC, laptop, PDA, robot, analytical, technological, universal, mathematical, artificial, intelligent, network, explore, in common, as a result.重點(diǎn)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(成龍)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

一、教學(xué)要求1、會寫7個生字。2、會認(rèn)13個字。3、正確、流利、有感情地朗讀課文。通過朗讀課文,知道鴨子和公雞的不同習(xí)性,懂得小伙伴之間要互相幫助。二、教材說明本課是一篇童話。講的是小公雞跟小鴨子一起玩,小公雞給小鴨子捉蟲子吃,小鴨子給小公雞捉魚吃。小公雞下河后差點(diǎn)被淹死,幸虧小鴨子救了它。課文饒有趣味地講了小雞和小鴨的不同習(xí)性,以及它們團(tuán)結(jié)友愛、互相幫助的美德。三、教學(xué)建議(一)教學(xué)準(zhǔn)備準(zhǔn)備本課的生字詞語卡片、放大的課文插圖、多媒體課件及朗讀課文的錄音帶。(二)識字、寫字教學(xué)學(xué)習(xí)生字。重點(diǎn)指導(dǎo)讀準(zhǔn)“他、河、說”和要求會認(rèn)的字“塊、捉”的音。
三、依據(jù)理念說教學(xué)目標(biāo)和教學(xué)重難點(diǎn)根據(jù)《語文新課程標(biāo)準(zhǔn)》對低年級閱讀教學(xué)的要求,本課時三維教學(xué)目標(biāo)分別為:1.是認(rèn)識12個生字,在學(xué)習(xí)生字過程中積累識字方法。2.是正確、流利、有感情地朗讀課文,培養(yǎng)學(xué)生初步的閱讀能力,學(xué)習(xí)語言的能力及自主學(xué)習(xí)的能力。3.鞏固識字的方法,體會朗讀的方法。4.從課文中受到要團(tuán)結(jié)友愛、互相幫助的教育四、說說學(xué)生一年級學(xué)生具有天真活潑,好奇好問,好模仿易感染的心理特點(diǎn),容易被直觀形象、新鮮活動的事物所吸引,并能在教師創(chuàng)設(shè)的情境中獲得體驗,達(dá)到情感共鳴、因此在教學(xué)中,我根據(jù)學(xué)生的身心特點(diǎn)設(shè)計情境,設(shè)計游戲,分解朗讀要求,分散識字難點(diǎn),讓學(xué)生在一堂課中能始終學(xué)得輕松,學(xué)得愉快。五、說說教學(xué)策略方法1、 創(chuàng)設(shè)情境法。創(chuàng)設(shè)故事情境,讓學(xué)生切身投入到情境中去。2、 趣味識字法。用賽讀排火車等方法鞏固識字。3、 以讀促悟法。指導(dǎo)朗讀,邊讀邊悟。
三、教學(xué)目標(biāo)根據(jù)素質(zhì)教育的要求以及本單元的訓(xùn)練重點(diǎn),結(jié)合聾生認(rèn)知、情感、思維等方面的實際情況,我制定了如下教學(xué)目標(biāo):1.理解課文內(nèi)容,正確、流利地朗讀課文。2.培養(yǎng)觀察能力、自主探究能力和語言表達(dá)能力。3.教育學(xué)生懂得小猴子見新扔舊的行為是不好的,明白做什么事都要專一才能有所收獲的道理。四、教學(xué)重、難點(diǎn)本課的關(guān)鍵是必須處理好形象的圖和抽象的文字之間的關(guān)系,因為只有圖文緊密結(jié)合了,才能使學(xué)生了解小猴子活動的順序和事物之間的聯(lián)系,從而有效的發(fā)展學(xué)生的語言和思維。五、說教法、學(xué)法1.教法結(jié)合學(xué)生的個體差異和不同的學(xué)習(xí)需求,依據(jù)本課故事性強(qiáng),畫面豐富,結(jié)構(gòu)類似的特點(diǎn),我主要采取了以下教學(xué)方法:(1)圖文結(jié)合的情景教學(xué)法。(2)以扶為主的扶放教學(xué)法。(3)讀思結(jié)合的品讀感悟法。
二、學(xué)生情況分析從學(xué)生的知識掌握和能力體系來看,這些學(xué)生經(jīng)過低段一學(xué)期的學(xué)習(xí)及本期前兩個單元的活動,有了一定的語言積累和口語表達(dá)能力,學(xué)習(xí)了圖文結(jié)合理解課文內(nèi)容的方法,初步學(xué)習(xí)了結(jié)合詞句的理解來理解課文內(nèi)容的一些方法,具有初步的思維理解能力和口頭表達(dá)能力。從年齡結(jié)構(gòu)和心理特點(diǎn)來分析,此時的學(xué)生大多五、六歲,還處于一個好動的階段,他們的有意注意維持不了多久,只有在老師的指導(dǎo)下,通過師生間民主、協(xié)作、自主、活動的實踐激起學(xué)生的興趣,發(fā)揮其主動性,學(xué)習(xí)效率才高。三、教學(xué)目標(biāo)設(shè)定根據(jù)教材分析,學(xué)情分析,以及語文教學(xué)跟其他學(xué)科的共同目的(也就是教學(xué)要立足于促進(jìn)學(xué)生的發(fā)展,為他們的終身學(xué)生、生活和工作奠定基礎(chǔ)這一目的)我將本課時的教學(xué)目標(biāo)定為四個方面:第一是德育目標(biāo),就是通過理解課文內(nèi)容,懂得我們從小做事應(yīng)該一心一意和不要亂摘別人的東西等道理。第二是智能目標(biāo):培養(yǎng)學(xué)生根據(jù)對課文重點(diǎn)詞句的理解和自己分析、推斷、想象、表演的能力。第三是知識目標(biāo),就是能理解重點(diǎn)詞“又大又多”、“又大又紅”、“又大又圓”、“可愛”、“掰、找、扔、摘、捧、扔、抱、追”以及相關(guān)的句子。第四是美育目標(biāo),通過理解重點(diǎn)詞語,體會到小猴的可愛;同時培養(yǎng)學(xué)生的語言表達(dá)形式和想象能力。
一、說教材小青蛙是小學(xué)一年級語文下冊第一單元識字課中的第三課,這是一首兒歌形式的字族文識字課,讀起來朗朗上口,音韻和諧,講述了小青蛙的外形和本領(lǐng),號召大家要保護(hù)小青蛙。本課共有12個生字,其中母體字“青”和不同的形旁搭配,構(gòu)成五個新字,形成了以“青”為基礎(chǔ)的一組音近、形近的形聲字,而這些字的意思在這首兒歌的情景中有具體體現(xiàn),于是這些字的音形義在語境中便巧妙的聯(lián)系起來,很有特點(diǎn)。二、說學(xué)情低年級孩子由于受年齡特點(diǎn)和認(rèn)知發(fā)展特點(diǎn)的限制,愛玩好動,思維活躍,表現(xiàn)欲強(qiáng),但持久性差。只有尊重孩子的天性,才能收到理想的學(xué)習(xí)效果,那么讓課堂充滿樂趣,不僅是低年級孩子的心理需求,也是語文教學(xué)、識字教學(xué)本身內(nèi)在的要求。另外,雖然孩子們已經(jīng)有半年的語文學(xué)習(xí)經(jīng)驗,但識字能力尚在形成過程中,教師仍需指導(dǎo)識字方法,讓學(xué)生跟著老師一起感悟。
2.教學(xué)目標(biāo)根據(jù)教學(xué)大綱的要求,本課教材的特點(diǎn),結(jié)合學(xué)生實際情況制定如下教學(xué)目標(biāo):(1)學(xué)會本課13個生字和由生字組成的新詞。(2)通過看圖,學(xué)習(xí)課文,理解詞句和每段的意思,了解小魚、黃牛、燕子、壁虎尾巴用處,及壁虎尾巴可以再生的特點(diǎn)。(3)能正確、流利的朗讀課文,了解其敘述方法。3.教學(xué)重難點(diǎn)教學(xué)重點(diǎn):學(xué)習(xí)小壁虎借尾巴的經(jīng)過,懂得魚、牛、燕子、壁虎尾巴的用處,接受禮貌教育。教學(xué)難點(diǎn):理解小壁虎尾巴的用處和特點(diǎn)。4.教具準(zhǔn)備小壁虎剪圖、課文錄音、課文幻燈片4框、CAI課件、魚模型。5.課時安排整課計劃3課時完成,第1課時初讀課文,認(rèn)識生字,學(xué)習(xí)課文1、2自然段,第2課時講讀三至七自然段并指導(dǎo)朗讀,總結(jié)全文,激發(fā)學(xué)生閱讀課外讀物的興趣。第3課時,識記生字的形,指導(dǎo)書寫,完成課后練習(xí)。
一、說教材《小青蛙》是一篇孩子們喜歡的兒歌。本組教材充分體現(xiàn)了工具性和人文性的統(tǒng)一。本文要求掌握的生字7 個,要求會認(rèn)的字12個。由于面對的是低年級學(xué)生。我盡量把識字和閱讀結(jié)合起來,以識字為主,閱讀為輔,以多種游戲的形式,使枯燥的識字教學(xué)”活“起來。二、說教法學(xué)法教法:新課標(biāo)倡導(dǎo)學(xué)生是學(xué)習(xí)和發(fā)展的主體,語文教學(xué)要關(guān)注學(xué)生的個體差異和不同的學(xué)習(xí)需求,愛護(hù)學(xué)生的好奇心、求知欲,充分激發(fā)學(xué)生的主動意識和進(jìn)取精神。因此,將教學(xué)方法確定為促進(jìn)學(xué)生自主、合作、探究性學(xué)習(xí)的“情境教學(xué)法”和“自主識字法?!苯虒W(xué)中要充分利用多媒體直觀教學(xué)手段,創(chuàng)設(shè)情境,開展活動,有張有弛,引導(dǎo)學(xué)生積極主動地投入到學(xué)習(xí)活動中去。
1、說教材:本節(jié)課是北師大版小學(xué)數(shù)學(xué)四年級下冊第94-95頁。猜數(shù)游戲是在學(xué)生已經(jīng)學(xué)習(xí)了用字母表示數(shù)、方程、等式的性質(zhì)等知識的基礎(chǔ)上進(jìn)行學(xué)習(xí)的。本節(jié)課主要學(xué)會用等式的性質(zhì)解“ax±b=c”這樣的方程,并能用方程解決簡單的實際問題。教材通過笑笑和淘氣猜數(shù)游戲,利用等量關(guān)系列出方程,重點(diǎn)是利用等式的性質(zhì)解方程,能口頭檢驗,形成檢驗的意識。本節(jié)課我通過游戲激發(fā)學(xué)生的興趣,使學(xué)生體會方程的作用,并產(chǎn)生學(xué)習(xí)方程解法的愿望,為以后學(xué)習(xí)解方程、用方程思想解決問題打下重要基礎(chǔ)。2、說教學(xué)目標(biāo):通過猜數(shù)游戲的這個情景,讓學(xué)生會解形如“ax±b=c”的方程,并會簡單應(yīng)用,讓學(xué)生在此過程中,體驗解方程的思路,并掌握方法。在情感、態(tài)度、價值觀方面,通過游戲,訓(xùn)練學(xué)生的數(shù)學(xué)思維能力,養(yǎng)成善于思考的習(xí)慣。3、說重、難點(diǎn):本節(jié)課的重點(diǎn)是會解形如“ax±b=c”的方程,并會簡單應(yīng)用;難點(diǎn)是利用等式的性質(zhì)解方程
教學(xué)目標(biāo):1、引導(dǎo)學(xué)生通過計算、比較、觀察、等實踐活動,使學(xué)生理解倒數(shù)的意義,掌握求倒數(shù)的方法,并能正確熟練的求出倒數(shù)。2、通過自主探究、合作交流的方式培養(yǎng)學(xué)生與人合作的能力。3、提高學(xué)生學(xué)習(xí)數(shù)學(xué)的興趣,發(fā)展學(xué)生質(zhì)疑的習(xí)慣。教學(xué)重點(diǎn):知道倒數(shù)的意義和會求一個數(shù)的倒數(shù)教學(xué)難點(diǎn):1、0的倒數(shù)的求法。二、說教法基于教材內(nèi)容比較單調(diào),那么只有在教法上體現(xiàn)新、奇、特,才能讓學(xué)生想學(xué)、要學(xué)。在教學(xué)過程中,我將始終扮演一個組織者、引導(dǎo)者、合作者的角色,根據(jù)小學(xué)生從具體的形象思維逐步向抽象的邏輯思維發(fā)展的思維特點(diǎn),聯(lián)系小學(xué)生熟悉的身邊實際,使抽象的內(nèi)容直觀化,激發(fā)學(xué)生的學(xué)習(xí)興趣,引導(dǎo)學(xué)生去發(fā)現(xiàn)問題、討論問題,放手讓他們自主探究和合作交流,幫助他們在自主探究、合作交流中真正理解并掌握本節(jié)課的數(shù)學(xué)知識、技能、思想和方法。
二、教學(xué)目標(biāo)的確立教學(xué)目標(biāo)根據(jù)學(xué)生的年齡特點(diǎn)、教學(xué)內(nèi)容,我確定了如下的教學(xué)目標(biāo):1.結(jié)合解決問題的過程,初步理解同分母分?jǐn)?shù)加減法算理,并能正確計算。2.能用同分母分?jǐn)?shù)的加減運(yùn)算,解決一些簡單的實際問題。3.在動手操作中,激發(fā)學(xué)生學(xué)習(xí)興趣,培養(yǎng)學(xué)生合作意識和勇于探索、自主學(xué)習(xí)的精神。三、教材處理本節(jié)課我充分尊重教材,將整節(jié)課至于生動的情境中,以觀察思考、動手實踐、合作交流為主要形式,使學(xué)生完成對知識的建構(gòu),同時感知數(shù)學(xué)與生活的聯(lián)系。根據(jù)教學(xué)目標(biāo)及學(xué)生的認(rèn)識規(guī)律我確定了:教學(xué)重點(diǎn):理解并掌握同分母分?jǐn)?shù)加減法的計算方法,并能通過運(yùn)算解決一些簡單的實際問題。教學(xué)難點(diǎn):解決“1減幾分之幾”的問題。四、教法學(xué)法教學(xué)中我采取“創(chuàng)設(shè)情境,自主探索,合作交流”開放式探究模式的教法,引導(dǎo)學(xué)生想學(xué)、樂學(xué)。創(chuàng)造主動參與,積極探究的氛圍,讓學(xué)生以動手操作,動眼觀察、動腦思考、同桌互學(xué),小組研討、集體評論的學(xué)法,讓學(xué)生全程參與到每個教學(xué)環(huán)節(jié)中來。
一、說教學(xué)內(nèi)容及目標(biāo)?!顿I電器》是北師大版二年級數(shù)學(xué)下冊第六單元“加與減(一)”的一課時。本科教材通過創(chuàng)設(shè)學(xué)生熟悉的買電器的生活情境,請學(xué)生提出相關(guān)的數(shù)學(xué)問題,學(xué)習(xí)整百、整十?dāng)?shù)相加減的口算。本節(jié)課是在學(xué)生掌握了100以內(nèi)加減法及萬以內(nèi)數(shù)的認(rèn)識的基礎(chǔ)上進(jìn)行的,學(xué)好本節(jié)課為今后進(jìn)一步學(xué)習(xí)整數(shù)加減法打下了堅實的基礎(chǔ)。對學(xué)生來說,對各種電器非常熟悉,并且有逛家電商場的經(jīng)歷,能根據(jù)情境提出相應(yīng)的加減法問題。孩子們能正確迅速地口算20以內(nèi)的加減法,部分學(xué)生能口算整百、整十?dāng)?shù)的加減法,但對于算理的理解比較欠缺。為此我確定以下教學(xué)目標(biāo)及重難點(diǎn)。教學(xué)目標(biāo):1、引導(dǎo)學(xué)生探索并掌握整十?dāng)?shù)、整百的加減計算方法,經(jīng)歷與他人交流計算方法的過程,并能正確計算。2、結(jié)合具體情境,提出用整十?dāng)?shù)、整百數(shù)解決的問題,發(fā)展提出問題和解決問題的意識和能力。
二、學(xué)情分析對于學(xué)生來說,在認(rèn)識角之前,已經(jīng)具備了有關(guān)角的感性經(jīng)驗。但是,低年級學(xué)生的認(rèn)知規(guī)律是以具體的形象思維為主,抽象思維能力較低。這部分內(nèi)容對于二年級學(xué)生來說比較抽象,接受起來較為困難。為了幫助學(xué)生更好的認(rèn)識角,形成角的表象。我設(shè)計了一些貼近學(xué)生生活的數(shù)學(xué)活動,讓孩子在實踐活動中經(jīng)過獨(dú)立思考,合作探究去認(rèn)識角,發(fā)現(xiàn)角,從而感受到生活中處處有角。三、教學(xué)目標(biāo)及重難點(diǎn)依據(jù)《課標(biāo)》的要求和教材的特點(diǎn),結(jié)合學(xué)生的生活實際及年齡特征,我確定了如下的教學(xué)目標(biāo):1、結(jié)合生活情境,感受生活中處處有角,體會數(shù)學(xué)與生活的密切聯(lián)系。2、通過摸一摸、找一找、搭一搭、畫一畫、比一比等活動讓學(xué)生直觀地認(rèn)識角,感受角的大小。
