    人教版新課標(biāo)高中物理必修2行星的運(yùn)動(dòng)說(shuō)課稿

    一、教材分析行星的運(yùn)動(dòng)選自人教版普通高中物理必修2第六章第1節(jié)。本節(jié)教學(xué)既是前面《運(yùn)動(dòng)的描述》和《曲線運(yùn)動(dòng)》內(nèi)容的進(jìn)一步的延伸和拓展,又能為后面學(xué)習(xí)萬(wàn)有引力定律做鋪墊。在本章中占有較為重要的地位,具有承前啟后的作用。同時(shí)該節(jié)內(nèi)容也涉及大量物理史實(shí)、貼近學(xué)生生活和聯(lián)系社會(huì)實(shí)際的事實(shí),可進(jìn)一步培育學(xué)生的科學(xué)情感、精神和發(fā)展觀。(一)教學(xué)目標(biāo) 1.知識(shí)與技能(1)知道地心說(shuō)和日心說(shuō)的基本內(nèi)容。(2.)掌握理解開(kāi)普勒三大定律的內(nèi)容,并能應(yīng)用。(3)理解人們對(duì)行星運(yùn)動(dòng)的認(rèn)識(shí)過(guò)程是漫長(zhǎng)復(fù)雜的,真理是來(lái)之不易的。2.過(guò)程與方法通過(guò)托勒密、哥白尼、第谷·布拉赫、開(kāi)普勒等幾位科學(xué)家對(duì)行星運(yùn)動(dòng)的不同認(rèn)識(shí),了解人類認(rèn)識(shí)事物本質(zhì)的曲折性并加深對(duì)行星運(yùn)動(dòng)的理解。3.情感、態(tài)度與價(jià)值觀(1)澄清對(duì)天體運(yùn)動(dòng)神秘、模糊的認(rèn)識(shí),掌握人類認(rèn)識(shí)自然規(guī)律的科學(xué)方法。(2)感悟科學(xué)是人類進(jìn)步不竭的動(dòng)力。

    人教版新課標(biāo)高中物理必修2圓周運(yùn)動(dòng)說(shuō)課稿3篇

    設(shè)計(jì)意圖:通過(guò)設(shè)疑、討論及學(xué)生的親身體驗(yàn)與教師的引導(dǎo),得到描述圓周運(yùn)動(dòng)快慢的兩個(gè)物理量,也就成功的打破了學(xué)生在認(rèn)識(shí)上的思維障礙,突破了物理概念教學(xué)的難點(diǎn)。在解決線速度和角速度的問(wèn)題之后,我將引領(lǐng)學(xué)生學(xué)習(xí)勻速圓周運(yùn)動(dòng)的概念以及勻速圓周運(yùn)動(dòng)中線速度、角速度的特點(diǎn)。并引出勻速圓周運(yùn)動(dòng)中周期、轉(zhuǎn)速的知識(shí)。為了加深學(xué)生對(duì)線速度、角速度與半徑關(guān)系的認(rèn)識(shí),我設(shè)計(jì)了第三個(gè)學(xué)生體驗(yàn)活動(dòng):四名學(xué)生以我為圓心做圓周運(yùn)動(dòng),四名學(xué)生始終并列,這時(shí)里圈同學(xué)走動(dòng)不急不慢,而外圈同學(xué)則要小跑。通過(guò)學(xué)生的活動(dòng),不難發(fā)現(xiàn)在角速度相同的情況下,半徑越大的線速度也越大。定性的得到了線速度、角速度與半徑的關(guān)系。接下來(lái)讓學(xué)生利用所學(xué)知識(shí)推導(dǎo)線速度、角速度與半徑的關(guān)系。設(shè)計(jì)意圖:這樣就通過(guò)設(shè)疑、學(xué)生猜想、體驗(yàn)、推導(dǎo)的方式得到了結(jié)論,突破了本節(jié)課的難點(diǎn)即線速度、角速度與半徑的關(guān)系。

    人教版新課標(biāo)高中物理必修1時(shí)間和位移說(shuō)課稿2篇

    研究一種物理現(xiàn)象,總是要先從現(xiàn)象的描述入手。機(jī)械運(yùn)動(dòng)作為自然界最簡(jiǎn)單和最基本的運(yùn)動(dòng)形態(tài),它所描述的是物體空間位置隨時(shí)間變化的情況。因此,本節(jié)學(xué)習(xí)描述質(zhì)點(diǎn)做機(jī)械運(yùn)動(dòng)需要時(shí)刻、時(shí)間間隔和位移等概念。相當(dāng)一部分高一學(xué)生在具體過(guò)程中難以區(qū)別時(shí)刻和時(shí)間間隔。另外,由于思維的定式,在第一次接觸既要考慮大小又要考慮方向的問(wèn)題時(shí),會(huì)因不適應(yīng)造成學(xué)習(xí)困難。所以,區(qū)別“路程與位移”“時(shí)刻和時(shí)間間隔”是教學(xué)的重難點(diǎn)所在。學(xué)習(xí)這些內(nèi)容的過(guò)程與方法對(duì)學(xué)習(xí)速度和加速度可以起到奠定基礎(chǔ)的作用。教學(xué)的對(duì)象是高一的學(xué)生,這一時(shí)期的學(xué)生處在好奇善問(wèn)、創(chuàng)新意識(shí)強(qiáng)烈的青少年期。對(duì)于生活中出現(xiàn)的各種現(xiàn)象具有濃厚的興趣。但他們的思維還停留在簡(jiǎn)單的代數(shù)運(yùn)算階段,對(duì)于矢量和矢量運(yùn)算的理性認(rèn)識(shí)幾乎沒(méi)有。且對(duì)生活中出現(xiàn)的時(shí)間、時(shí)刻、時(shí)間間隔等不能做出很好的區(qū)分,對(duì)時(shí)常提及的路程、距離等形成了模糊的前概念。

    人教版高中生物必修1細(xì)胞中的無(wú)機(jī)物說(shuō)課稿

    為了加強(qiáng)學(xué)生的理解,讓學(xué)生討論以下問(wèn)題。由師生共同總結(jié)。播放一個(gè)短時(shí)視頻,讓學(xué)生認(rèn)識(shí)到水的重要性后,展示節(jié)水標(biāo)識(shí),說(shuō)明由來(lái)。細(xì)胞中的無(wú)機(jī)鹽這部分,我將展示圖表,并列出問(wèn)題:表中哪些成分屬于無(wú)機(jī)鹽?為什么要在運(yùn)動(dòng)員喝的飲料中添加無(wú)機(jī)鹽?無(wú)機(jī)鹽在細(xì)胞的生活中起什么作用?然后展示廣告語(yǔ),讓學(xué)生思考和討論以下問(wèn)題,并得到答案。再閱讀課本,驗(yàn)證自己的答案是否正確。關(guān)于無(wú)機(jī)鹽的作用較難理解,通過(guò)列舉人體生活與健康中的各種實(shí)例來(lái)加深感性認(rèn)識(shí),加強(qiáng)對(duì)理論知識(shí)的理解3、課堂小結(jié),強(qiáng)化認(rèn)識(shí)。(3—5分鐘)課堂小結(jié),可以把課堂傳授的知識(shí)盡快地轉(zhuǎn)化為學(xué)生的素質(zhì);簡(jiǎn)單扼要的課堂小結(jié),可使學(xué)生更深刻地理解理論知識(shí)在實(shí)際生活中的應(yīng)用,并且逐漸地培養(yǎng)學(xué)生具有良好的個(gè)性。4、板書設(shè)計(jì)我比較注重直觀、系統(tǒng)的板書設(shè)計(jì),還及時(shí)地體現(xiàn)教材中的知識(shí)點(diǎn),以便于學(xué)生能夠理解掌握。5、布置作業(yè)。

    3.甲午中日戰(zhàn)爭(zhēng)中國(guó)戰(zhàn)敗的原因 對(duì)于“中國(guó)戰(zhàn)敗的原因”這一難點(diǎn)的突破,主要通過(guò)設(shè)置問(wèn)題“中國(guó)之?dāng)≡趯?shí)力遜于日本嗎?”通過(guò)幻燈片全方位分析其實(shí)中國(guó)的綜合國(guó)力當(dāng)時(shí)是強(qiáng)于日本的。并且在戰(zhàn)前,日本毫無(wú)取勝的把握。讓學(xué)生結(jié)合剛學(xué)習(xí)過(guò)的戰(zhàn)爭(zhēng)原因和經(jīng)過(guò)進(jìn)行討論,從多方面分析中國(guó)戰(zhàn)敗的原因。經(jīng)過(guò)討論,學(xué)生可以得出以下結(jié)論:避戰(zhàn)自保方針,沒(méi)有積極備戰(zhàn),將領(lǐng)臨陣脫逃,教師肯定并總結(jié)答案進(jìn)行補(bǔ)充。中日對(duì)比:中國(guó)士兵出身農(nóng)民,軍事訓(xùn)練落后,散兵游勇;日本士兵出身武士,訓(xùn)練有素;中國(guó)將領(lǐng)大多臨陣脫逃,并相互猜忌,受當(dāng)時(shí)惡劣的官風(fēng)影響;李鴻章深知北洋海軍實(shí)情,缺乏軍費(fèi),軍備廢弛。為政治資本奉行避戰(zhàn)自保政策,慈禧太后挪用海軍軍費(fèi)過(guò)壽,支持李鴻章。使中方處于被動(dòng)的局面,一再貽誤戰(zhàn)機(jī)。而日本在天皇的帶動(dòng)下,全民備戰(zhàn),做了充分的戰(zhàn)爭(zhēng)準(zhǔn)備。

    人教版高中語(yǔ)文必修3《祝福》說(shuō)課稿3篇

    各位評(píng)委老師,大家好。我說(shuō)課的題目是《祝?!?。一、說(shuō)教材(一)教材所處的位置和地位高中語(yǔ)文新課程教材必修五本書,共有2個(gè)單元中外小說(shuō)單元。一個(gè)必修3的第一單元,一個(gè)是必修5的第一單元,共六篇文章。(《林黛玉進(jìn)賈府》《祝?!贰独先伺c?!贰读纸填^風(fēng)雪山神廟》《裝在套子里的人》《邊城》)《祝福》是屬于前者。小說(shuō)是擁有眾多讀者的一種文體,它可以多方面刻畫人物性格,描摹人物心理,完整地表現(xiàn)人物之間的沖突,還可以具體生動(dòng)地再現(xiàn)人物生活的環(huán)境,因此在反映復(fù)雜的社會(huì)生活方面具有獨(dú)特優(yōu)勢(shì)。所以學(xué)習(xí)小說(shuō)這種文學(xué)樣式,也是有助于學(xué)生學(xué)會(huì)鑒賞小說(shuō)的基本方法,為將來(lái)的小說(shuō)閱讀打下基礎(chǔ)。魯迅的《祝福》是中國(guó)現(xiàn)代小說(shuō)的精品,當(dāng)中的人物祥林嫂也是魯迅小說(shuō)中與阿Q、孔乙己三個(gè)最為出名的人物之一。研讀好這篇文章,對(duì)將來(lái)小說(shuō)的閱讀,小說(shuō)中人物的理解,甚至小說(shuō)的寫作都有深廣意義。

    二、學(xué)生情況分析(說(shuō)學(xué)法)1、學(xué)生學(xué)習(xí)基礎(chǔ)分析:學(xué)生通過(guò)對(duì)《生活與哲學(xué)》前面三個(gè)單元的學(xué)習(xí),初步掌握了運(yùn)用唯物論、辯證法、認(rèn)識(shí)論的觀點(diǎn)去認(rèn)識(shí)問(wèn)題、分析問(wèn)題的能力;再通過(guò)對(duì)第十一課的學(xué)習(xí),學(xué)生對(duì)馬克思主義的歷史觀有了初步的理解,初步樹(shù)立了正確的理想信念,這為本課教學(xué)目標(biāo)的落實(shí)奠定了知識(shí)基礎(chǔ)。 2、學(xué)生能力分析 :高二學(xué)生擁有一定生活體驗(yàn),具備一定的信息收集和篩選能力、閱讀能力、語(yǔ)言表達(dá)能力、對(duì)問(wèn)題的一定的探究能力,同伴合作能力和具備初步邏輯思維能力。3、學(xué)生心理分析:在我國(guó)現(xiàn)階段,以為人民服務(wù)為核心的社會(huì)主義道德建設(shè)過(guò)程中涌現(xiàn)了大批的先進(jìn)人物和道德典范,但同時(shí)由于社會(huì)價(jià)值的多元化,個(gè)人主義、享樂(lè)主義、拜金主義等資本主義腐朽思想也同樣在影響著當(dāng)代的中學(xué)生。
