人教版新課標(biāo)高中物理必修2圓周運(yùn)動說課稿3篇
設(shè)計意圖：通過設(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)動快慢的兩個物理量，也就成功的打破了學(xué)生在認(rèn)識上的思維障礙，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題之后，我將引領(lǐng)學(xué)生學(xué)習(xí)勻速圓周運(yùn)動的概念以及勻速圓周運(yùn)動中線速度、角速度的特點(diǎn)。并引出勻速圓周運(yùn)動中周期、轉(zhuǎn)速的知識。為了加深學(xué)生對線速度、角速度與半徑關(guān)系的認(rèn)識，我設(shè)計了第三個學(xué)生體驗(yàn)活動：四名學(xué)生以我為圓心做圓周運(yùn)動，四名學(xué)生始終并列，這時里圈同學(xué)走動不急不慢，而外圈同學(xué)則要小跑。通過學(xué)生的活動，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。接下來讓學(xué)生利用所學(xué)知識推導(dǎo)線速度、角速度與半徑的關(guān)系。設(shè)計意圖：這樣就通過設(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2探究彈性勢能的表達(dá)式說課稿4篇
設(shè)疑自探：一個壓縮或拉伸的彈簧就是一個“儲能器”，怎樣衡量形變彈簧蘊(yùn)含能量的多少呢？彈簧的彈性勢能的表達(dá)式可能與那幾個物理量有關(guān)？類比：物體的重力勢能與物體所受的重力和高度有關(guān)。那么彈簧的彈性勢能可能與所受彈力的大小和在彈力方向上的位置變化有關(guān)，而由F=kl知彈簧所受彈力等于彈簧的勁度系數(shù)與形變量的乘積。預(yù)測：彈簧的彈性勢能與彈簧的勁度系數(shù)和形變量有關(guān)。學(xué)生討論如何設(shè)計實(shí)驗(yàn)： ①、用同一根彈簧在幾次被壓縮量不同時釋放（勁度系數(shù)相同，改變形變量），觀察小車被彈開的情況。②、分別用兩根彈簧在被壓縮量相同時釋放（形變量相同，勁度系數(shù)不同），觀察小車被彈開的情況。交流探究結(jié)果：彈性勢能隨彈簧形變量增大而增大。隨彈簧的勁度系數(shù)的增大而增大。

2、學(xué)生分析 九十年代初期出生的孩子，生活在一個充滿活力的時代，張揚(yáng)個性成為他（她）們的主旋律。面對這一時代的學(xué)生，溝通需要用心、用技巧，那也是一門藝術(shù)。高中學(xué)生的心理日趨成熟,有一定的知識積累,且比較豐富;語言邏輯性強(qiáng),有較強(qiáng)的參與意識,求知欲望及表現(xiàn)欲望。學(xué)生主體參與的充分，表現(xiàn)在其主動性，積極性得到極大的調(diào)動。這與教師的主導(dǎo)作用是分不開的。本課教案就是要引導(dǎo)學(xué)生自己先閱讀書本、獨(dú)立思考、激發(fā)學(xué)生思維，引導(dǎo)學(xué)生各抒己見，讓學(xué)生自己得出解答問題的結(jié)論，不追求答案的唯一。充分體現(xiàn)了讀書是一種個體行為，每個學(xué)生有不同的體驗(yàn)。教師應(yīng)跳出教案的問題模式，和學(xué)生一道去創(chuàng)造地發(fā)現(xiàn)問題、分析問題、解決問題，在成功中尋找快樂、在快樂中更加成功。同時特別注重創(chuàng)設(shè)的情景的選擇性，有針對性和實(shí)效性，引導(dǎo)學(xué)生們積極、主動參與，使他們的潛能、智慧得出充分挖掘、展示。只有當(dāng)學(xué)生們在課堂上表現(xiàn)出來的獨(dú)特的、有創(chuàng)意的設(shè)計見解，學(xué)生主體參與和教師主導(dǎo)二者完美結(jié)合，才能表明該課的設(shè)計卓有成效。
人教版高中政治必修3文化在交流中傳播說課稿2篇
師：同學(xué)們這個暑假過得真不錯呀，都有自己最開心的日子。同學(xué)們經(jīng)歷的這些活動，讓你們自己長了知識，豐富了閱歷，你們今天的介紹，也讓我和更多的同學(xué)大開了眼界。由此可見，在今天，通過親身參與、實(shí)踐，通過網(wǎng)絡(luò)、電影，通過交流發(fā)言，大家獲得了許多新的信息、知識，增強(qiáng)了對祖國美好河山的熱愛、對科技的向往和異國的友誼。同學(xué)們信息交流的過程，實(shí)際上也是文化傳播的過程。板書課題:第二課時文化在交流中傳播話題導(dǎo)入討論話題：如何建設(shè)文明校園?（課前準(zhǔn)備：要求同學(xué)們仔細(xì)觀察、了解關(guān)于校園文明現(xiàn)象的問題，并就如何建設(shè)文明校園提出自己的建議。教師可按自然組，讓學(xué)生推選一名代表發(fā)言，就校園文明方面談?wù)劥嬖诘膯栴}和不足，或提出一些中肯的改進(jìn)意見）（學(xué)生交流）生1：建設(shè)文明校園，首先要凈化語言環(huán)境，我們學(xué)校不少同學(xué)愛說臟話，與文明校園很不相稱。

師：在科學(xué)發(fā)展過程中，前一個理論體系的不完善之處，往往是新的研究和新的發(fā)現(xiàn)的突破口。開普勒之后，意大利天文學(xué)家伽利略創(chuàng)制了天文望遠(yuǎn)鏡，用更加精確的觀察繼續(xù)發(fā)展和驗(yàn)證哥白尼創(chuàng)立的新天文學(xué)理論。除了用望遠(yuǎn)鏡進(jìn)行天文觀察以外，伽利略還開始進(jìn)行自然科學(xué)的實(shí)驗(yàn)研究，哪位同學(xué)能給大家講一講伽利略在比薩斜塔上所作的關(guān)于物體自由下落的實(shí)驗(yàn)？生：（講述這一實(shí)驗(yàn)）師：所以，伽利略在科學(xué)方面更加重要的貢獻(xiàn)是奠定了近代實(shí)驗(yàn)科學(xué)的基礎(chǔ)。（2）實(shí)驗(yàn)科學(xué)和唯物主義師：伽利略從實(shí)踐上開辟了實(shí)驗(yàn)科學(xué)的方法，而英國唯物主義哲學(xué)家培根則從理論上闡述了實(shí)驗(yàn)科學(xué)的方法——?dú)w納法。培根和伽利略同被稱為實(shí)驗(yàn)科學(xué)之父，培根還有一句影響深刻的名言：“知識就是力量”，表明了他注重知識，尊崇科學(xué)的精神。我們再來概括一下意大利哲學(xué)家布魯諾的唯物主義思想，是否有同學(xué)可以簡述布魯諾的生平事跡？

人教版高中歷史必修1辛亥革命教案2篇
①從政府人員組成看，南京政府是一個以資產(chǎn)階級革命派為主體的政府。②從政府頒發(fā)的法令和措施看，這些法令體現(xiàn)了資產(chǎn)階級民主革命的要求，對于發(fā)展民族資本主義經(jīng)濟(jì)、資產(chǎn)階級民主政治和文化教育以及改革社會風(fēng)氣，都起了積極作用。③從頒布的《中華民國臨時約法》看，憲法體現(xiàn)了三權(quán)分立的政治體制，體現(xiàn)了資產(chǎn)階級民主主義的要求，是中國歷史上第一部資產(chǎn)階級民主憲法，具有反封建專制制度的進(jìn)步意義。（2）從南京臨時政府的內(nèi)外政策分析南京政府的根本弱點(diǎn)①未徹底地反封建。它沒有采取比較徹底的反對封建主義的措施，特別是對封建統(tǒng)治的基礎(chǔ)——地主階級土地所有制沒有觸動，這樣，南京臨時政府也就不能真正地把廣大人民群眾動員起來，因而缺乏真正的群眾基礎(chǔ)。

This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2. Instruct students to write essays using the proper relative pronouns and adverbs of attributive clauses.本節(jié)語法思考：定語從句在復(fù)合句中的作用是什么？ 關(guān)系詞有哪些？定語從句在復(fù)合句中的作用相當(dāng)于形容詞，它在句中作定語修飾名詞或代詞。他們在先行詞和定語從句之間起到聯(lián)系作用，同時在意義上代表先行詞并在定語從句中擔(dān)任一個成分。被定語從句所修飾的詞稱先行詞，定語從句一般放在先行詞的后面。
