活動一:課本第三頁的活動題,把學(xué)生分成幾組然后讓他們讀圖討論,思考書上的幾個問題,最后派個代表回答問題.最后教師做適當(dāng)?shù)难a(bǔ)充:人口的自然增長不僅與人口自然增長率有關(guān)，而且還與人口基數(shù)有關(guān).活動二:課本第七頁的活動,先讓兩位學(xué)生閱讀第六頁的案例結(jié)合活動題思考問題,讓幾個組學(xué)生討論所給的幾個問題.讓學(xué)生歸納最后教師做適當(dāng)?shù)难a(bǔ)充.時間安排:由于本節(jié)內(nèi)容不難因此整個教學(xué)過程是一節(jié)課的時間來完成的因此在教學(xué)過程中注意時間的把握,在做活動和討論時注意把握時間,自己盡量少說廢話.課堂小結(jié)通過這一節(jié)的學(xué)習(xí)，同學(xué)們正確理解和認(rèn)識人口增長,增長模式和人口增長模式的轉(zhuǎn)變。我們可以利用比較法、分析法來掌握，并聯(lián)系現(xiàn)實(shí)生活，進(jìn)行分析、判斷，化理論知識于實(shí)踐之中。

1.兩圓x2+y2-1=0和x2+y2-4x+2y-4=0的位置關(guān)系是( )A.內(nèi)切 B.相交 C.外切 D.外離解析:圓x2+y2-1=0表示以O(shè)1(0,0)點(diǎn)為圓心,以R1=1為半徑的圓.圓x2+y2-4x+2y-4=0表示以O(shè)2(2,-1)點(diǎn)為圓心,以R2=3為半徑的圓.∵|O1O2|=√5,∴R2-R1<|O1O2|<R2+R1,∴圓x2+y2-1=0和圓x2+y2-4x+2y-4=0相交.答案:B2.圓C1:x2+y2-12x-2y-13=0和圓C2:x2+y2+12x+16y-25=0的公共弦所在的直線方程是 . 解析:兩圓的方程相減得公共弦所在的直線方程為4x+3y-2=0.答案:4x+3y-2=03.半徑為6的圓與x軸相切,且與圓x2+(y-3)2=1內(nèi)切,則此圓的方程為( )A.(x-4)2+(y-6)2=16 B.(x±4)2+(y-6)2=16C.(x-4)2+(y-6)2=36 D.(x±4)2+(y-6)2=36解析:設(shè)所求圓心坐標(biāo)為(a,b),則|b|=6.由題意,得a2+(b-3)2=(6-1)2=25.若b=6,則a=±4;若b=-6,則a無解.故所求圓方程為(x±4)2+(y-6)2=36.答案:D4.若圓C1:x2+y2=4與圓C2:x2+y2-2ax+a2-1=0內(nèi)切,則a等于 . 解析:圓C1的圓心C1(0,0),半徑r1=2.圓C2可化為(x-a)2+y2=1,即圓心C2(a,0),半徑r2=1,若兩圓內(nèi)切,需|C1C2|=√(a^2+0^2 )=2-1=1.解得a=±1. 答案:±1 5. 已知兩個圓C1:x2+y2=4,C2:x2+y2-2x-4y+4=0,直線l:x+2y=0,求經(jīng)過C1和C2的交點(diǎn)且和l相切的圓的方程.解:設(shè)所求圓的方程為x2+y2+4-2x-4y+λ(x2+y2-4)=0,即(1+λ)x2+(1+λ)y2-2x-4y+4(1-λ)=0.所以圓心為 1/(1+λ),2/(1+λ) ,半徑為1/2 √((("-" 2)/(1+λ)) ^2+(("-" 4)/(1+λ)) ^2 "-" 16((1"-" λ)/(1+λ))),即|1/(1+λ)+4/(1+λ)|/√5=1/2 √((4+16"-" 16"(" 1"-" λ^2 ")" )/("(" 1+λ")" ^2 )).解得λ=±1,舍去λ=-1,圓x2+y2=4顯然不符合題意,故所求圓的方程為x2+y2-x-2y=0.

1.探究：根據(jù)基本事實(shí)的推論2,3，過兩條平行直線或兩條相交直線，有且只有一個平面，由此可以想到，如果一個平面內(nèi)有兩條相交或平行直線都與另一個平面平行，是否就能使這兩個平面平行？如圖（1），a和b分別是矩形硬紙板的兩條對邊所在直線，它們都和桌面平行，那么硬紙板和桌面平行嗎？如圖（2），c和d分別是三角尺相鄰兩邊所在直線，它們都和桌面平行，那么三角尺與桌面平行嗎？2.如果一個平面內(nèi)有兩條平行直線與另一個平面平行，這兩個平面不一定平行。我們借助長方體模型來說明。如圖，在平面A’ADD’內(nèi)畫一條與AA’平行的直線EF,顯然AA’與EF都平行于平面DD’CC’,但這兩條平行直線所在平面AA’DD’與平面DD’CC’相交。3.如果一個平面內(nèi)有兩條相交直線與另一個平面平行，這兩個平面是平行的，如圖，平面ABCD內(nèi)兩條相交直線A’C’,B’D’平行。

人教版高中歷史必修3宋明理學(xué)說課稿3篇
陸王心學(xué)與程朱理學(xué)相比有何異同？生 不同點(diǎn)：在理的內(nèi)涵上不同，程朱理學(xué)認(rèn)為“理”是貫通于宇宙、人倫的客觀存在，是一種普遍的規(guī)律準(zhǔn)則；陸王心學(xué)認(rèn)為心即理，是“良知”，認(rèn)為人心便是世界萬物的本原。方法上也有不同：前者向外追究，“格物致知”；后者向內(nèi)探求，“發(fā)明本心”以求理，克服私欲、回復(fù)良知。生 相同點(diǎn)：都提出了一個宇宙、社會、人生遵循的“理”。師 對。程朱理學(xué)是客觀唯心主義，陽明心學(xué)是主觀唯心主義。這兩者的分歧是理學(xué)范圍內(nèi)的分歧，其基本思想是一致的。師 宋明理學(xué)與漢唐以前的儒學(xué)比較，最大的特點(diǎn)在于批判地吸收了佛教哲學(xué)的思辨結(jié)構(gòu)和道教的宇宙生成論，將儒家的倫理學(xué)說概括升華為哲學(xué)基本問題。其實(shí)質(zhì)是把佛、道“養(yǎng)性”“修身”引向儒家的“齊家”“治國”“平天下”，對儒家的綱常道德給予哲學(xué)論證，使之神圣化、絕對化、普遍化，以便深入人心，做到人人遵而行之。

（二）組織學(xué)生探究知識并形成新的知識。我從學(xué)生的生活體驗(yàn)入手，運(yùn)用案例等形式創(chuàng)設(shè)情境呈現(xiàn)問題，使學(xué)生在自主探索、合作交流的過程中，發(fā)現(xiàn)問題、分析問題、解決問題，在問題的分析與解決中主動構(gòu)建知識。主要通過幾幅漫畫讓學(xué)生思考其中的哲學(xué)道理，開始接觸哲學(xué)。漫畫一：種瓜得瓜，種豆得豆，種雞蛋得??漫畫二：甲：下雨好極啦！乙：下雨糟透了！漫畫三：——狂妄之徒，你竟然壞了祖上規(guī)矩！在引導(dǎo)學(xué)生思考、體驗(yàn)問題的過程中，可以使學(xué)生逐步學(xué)會分析、解決問題的方法。這樣做既有利于發(fā)展學(xué)生的理解、分析、概括、想象等創(chuàng)新思維能力，又有利于學(xué)生表達(dá)、動手、協(xié)作等實(shí)踐能力的提高，促進(jìn)學(xué)生全面發(fā)展，力求實(shí)現(xiàn)教學(xué)過程與教學(xué)結(jié)果并重，知識與能力并重的目標(biāo)。
人教版高中語文必修3《勸學(xué)》說課稿3篇
《勸學(xué)》是普通高中課程標(biāo)準(zhǔn)試驗(yàn)教科書語文必修三第三單元的重點(diǎn)篇目，該文集中反映著名思想家荀子在學(xué)習(xí)問題上的觀點(diǎn)和精彩斐然的論證藝術(shù)。該單元所選課文都是古代的議論性散文。通過本單元的學(xué)習(xí)在于讓學(xué)生感受我國傳統(tǒng)文化的精神，掌握基礎(chǔ)的文言語法知識，學(xué)習(xí)如何清晰有力的表達(dá)自己的思想和見解。本文安排在單元的第一篇，如何指導(dǎo)學(xué)生學(xué)好這篇課文，是實(shí)現(xiàn)“授之以漁”，樹立學(xué)生學(xué)好文言文的信心，掌握文言學(xué)習(xí)方法的關(guān)鍵。根據(jù)新課標(biāo)倡導(dǎo)從“知識與能力”、“過程與方法”、“情感態(tài)度與價值觀”三方面出發(fā)設(shè)計課程目標(biāo)的要求和高一的學(xué)生對于文言文的知識還在積累的階段，應(yīng)該注重基礎(chǔ)知識的積累和一定量的誦讀的實(shí)際情況。我擬確定以下教學(xué)目標(biāo)：1，了解荀子論述學(xué)習(xí)的思想，明確學(xué)習(xí)要靠積累、堅持不懈、專心致志的道理。2，掌握積累文言實(shí)詞、虛詞，活用、古今異議等現(xiàn)象和固定句式。
傾斜角與斜率教學(xué)設(shè)計人教A版高中數(shù)學(xué)選擇性必修第一冊
(2)l的傾斜角為90°,即l平行于y軸,所以m+1=2m,得m=1.延伸探究1 本例條件不變,試求直線l的傾斜角為銳角時實(shí)數(shù)m的取值范圍.解:由題意知(m"-" 1"-" 1)/(m+1"-" 2m)>0,解得1<m<2.延伸探究2 若將本例中的“N(2m,1)”改為“N(3m,2m)”,其他條件不變,結(jié)果如何?解:(1)由題意知(m"-" 1"-" 2m)/(m+1"-" 3m)=1,解得m=2.(2)由題意知m+1=3m,解得m=1/2.直線斜率的計算方法(1)判斷兩點(diǎn)的橫坐標(biāo)是否相等,若相等,則直線的斜率不存在.(2)若兩點(diǎn)的橫坐標(biāo)不相等,則可以用斜率公式k=(y_2 "-" y_1)/(x_2 "-" x_1 )(其中x1≠x2)進(jìn)行計算.金題典例 光線從點(diǎn)A(2,1)射到y(tǒng)軸上的點(diǎn)Q,經(jīng)y軸反射后過點(diǎn)B(4,3),試求點(diǎn)Q的坐標(biāo)及入射光線的斜率.解:(方法1)設(shè)Q(0,y),則由題意得kQA=-kQB.∵kQA=(1"-" y)/2,kQB=(3"-" y)/4,∴(1"-" y)/2=-(3"-" y)/4.解得y=5/3,即點(diǎn)Q的坐標(biāo)為 0,5/3 ,∴k入=kQA=(1"-" y)/2=-1/3.(方法2)設(shè)Q(0,y),如圖,點(diǎn)B(4,3)關(guān)于y軸的對稱點(diǎn)為B'(-4,3), kAB'=(1"-" 3)/(2+4)=-1/3,由題意得,A、Q、B'三點(diǎn)共線.從而入射光線的斜率為kAQ=kAB'=-1/3.所以,有(1"-" y)/2=(1"-" 3)/(2+4),解得y=5/3,點(diǎn)Q的坐標(biāo)為(0,5/3).
