人教版高中地理必修2煤城焦作出路何在說(shuō)課稿
分析過(guò)焦作市的地理概況和產(chǎn)業(yè)優(yōu)勢(shì)后，就需要針對(duì)由于資源枯竭所帶來(lái)的問(wèn)題提出合理化的建議。既然是談經(jīng)濟(jì)轉(zhuǎn)型，就應(yīng)該將話題的范圍明確在這一領(lǐng)域內(nèi)。通過(guò)材料3的相關(guān)內(nèi)容，我們了解到焦作市需要在產(chǎn)業(yè)結(jié)構(gòu)調(diào)整、培育新的優(yōu)勢(shì)產(chǎn)業(yè)、增強(qiáng)綜合競(jìng)爭(zhēng)力等三個(gè)整改方針上下功夫。因而引導(dǎo)學(xué)生針對(duì)優(yōu)勢(shì)與不足提出建議，以三個(gè)整改方針為基準(zhǔn)，衡量建議的可行性是鍛煉學(xué)生解決此類(lèi)問(wèn)題的有效途徑。在此我將教會(huì)學(xué)生的是解決問(wèn)題方法而非案例的內(nèi)容，正所謂“授之以魚(yú)，不如授之以漁”。接下來(lái)針對(duì)學(xué)生的建議和教材資料分析所羅列的10點(diǎn)整改思路，由學(xué)生自由發(fā)言提出看法，通過(guò)教師的指導(dǎo)和學(xué)生的討論，進(jìn)而確定經(jīng)濟(jì)轉(zhuǎn)型建議的具體方案。最后注意將建議與產(chǎn)業(yè)優(yōu)勢(shì)相對(duì)照，看建議是否都是圍繞著產(chǎn)業(yè)優(yōu)勢(shì)而提出的，這樣做會(huì)加深學(xué)生的印象，通過(guò)建議和優(yōu)勢(shì)的對(duì)應(yīng)關(guān)系，將不難找出此類(lèi)問(wèn)題的解題思路。

[設(shè)計(jì)說(shuō)明]：只給出情景故事，感知了一個(gè)大數(shù)，這樣還不能引起學(xué)生對(duì)大數(shù)的深刻認(rèn)識(shí)，所以再給出宇宙星空中的這些大數(shù)，讓學(xué)生讀讀、看看這些數(shù)，引起學(xué)生強(qiáng)烈的認(rèn)知上的沖突，形成一種心理上的想讀、想寫(xiě)的求知欲望。(二)、引出問(wèn)題、探索新知在上面的例子中，我們遇到了幾個(gè)很大的數(shù)，看起來(lái)、讀起來(lái)、寫(xiě)起來(lái)都不方便，有沒(méi)有簡(jiǎn)單的表示法呢?分以下步驟完成。1、回憶100 ，1000，10000，能寫(xiě)成10( )2、300=3×100=3×10( )3000=3×1000=3×10()30000=3×10000=3×10()3、再由學(xué)生完成上面4個(gè)例子中的數(shù)的表示。(學(xué)生對(duì)160 000 000 000這個(gè)數(shù)可能表示為、16×1010，教師要利用學(xué)生這種錯(cuò)誤，強(qiáng)調(diào)a的范圍)4、教師給出科學(xué)記數(shù)法表示：a×10( )(1≤a<10)。[設(shè)計(jì)說(shuō)明]：通過(guò)層層遞進(jìn)的探究設(shè)計(jì)，啟發(fā)學(xué)生成功地發(fā)現(xiàn)“科學(xué)記數(shù)法”的表示方法，同時(shí)又通過(guò)學(xué)生示錯(cuò)，讓學(xué)生記住a的范圍，體現(xiàn)了以學(xué)生為主的探究式教學(xué)。

五、課堂設(shè)計(jì)理念本節(jié)課著力體現(xiàn)以下幾個(gè)方面：1、突出問(wèn)題的應(yīng)用意識(shí)。在各個(gè)環(huán)節(jié)的安排上都設(shè)計(jì)成一個(gè)個(gè)問(wèn)題，使學(xué)生能?chē)@問(wèn)題展開(kāi)討思考、討論，進(jìn)行學(xué)習(xí)。2、體現(xiàn)學(xué)生的主體意識(shí)。讓學(xué)生通過(guò)列算式與列方程的比較，分別歸納出它們的特點(diǎn)，從而感受到從算術(shù)方法到代數(shù)方法是數(shù)學(xué)的進(jìn)步；讓學(xué)生通過(guò)合作交流，得出問(wèn)題的不同解法；讓學(xué)生對(duì)一節(jié)課的學(xué)習(xí)內(nèi)容、方法、注意點(diǎn)等進(jìn)行歸納。3、體現(xiàn)學(xué)生思維的層次性。教師首先引導(dǎo)學(xué)生嘗試用算術(shù)方法解決問(wèn)題，然后再引導(dǎo)學(xué)生列出含未知數(shù)的式了，尋找相等關(guān)系列出方程，在尋找相等關(guān)系、設(shè)未知數(shù)及作業(yè)的布置等環(huán)節(jié)中都注意了學(xué)生思維的層次性。4、滲透建模思想。把實(shí)際問(wèn)題中的數(shù)量關(guān)系用方程形式表示出來(lái)，就是建立一種數(shù)學(xué)模型，教師有意識(shí)地按設(shè)未知數(shù)、列方程等步驟組織學(xué)生學(xué)習(xí)，就是培養(yǎng)學(xué)生由實(shí)際問(wèn)題抽象出方程模型的能力。
北師大初中數(shù)學(xué)七年級(jí)上冊(cè)有理數(shù)說(shuō)課稿
1、 教材的地位和作用本課教材所處位置，是小學(xué)所學(xué)算術(shù)數(shù)之后數(shù)的范圍的第一次擴(kuò)充，是算術(shù)數(shù)到有理數(shù)的銜接與過(guò)渡，并且是以后學(xué)習(xí)數(shù)軸、相反數(shù)、絕對(duì)值以及有理數(shù)運(yùn)算的基礎(chǔ).2、 教學(xué)目標(biāo)①理解有理數(shù)產(chǎn)生的必然性、合理性及有理數(shù)的分類(lèi)；②能辨別正、負(fù)數(shù)，感受規(guī)定正、負(fù)的相對(duì)性；③體驗(yàn)中國(guó)古代在數(shù)的發(fā)展方面的貢獻(xiàn).3、 教學(xué)重點(diǎn)和難點(diǎn)教學(xué)重點(diǎn)：理解正數(shù)和負(fù)數(shù)的概念和有理數(shù)概念.教學(xué)難點(diǎn)：對(duì)負(fù)數(shù)概念的理解和有理數(shù)的分類(lèi).二、 教學(xué)分析鑒于初一年級(jí)學(xué)生的年齡特點(diǎn)，他們對(duì)概念的理解能力不強(qiáng)，精神不能長(zhǎng)時(shí)間集中，但思維比較活躍。我決定采取啟發(fā)式教學(xué)法及情感教學(xué)，創(chuàng)設(shè)問(wèn)題情境，引導(dǎo)學(xué)生主動(dòng)思考，用大量的實(shí)例和生動(dòng)的語(yǔ)言激發(fā)學(xué)生學(xué)習(xí)興趣，調(diào)節(jié)學(xué)習(xí)情緒。

（五）、反饋矯正，注重參與： 為鞏固本節(jié)的教學(xué)重點(diǎn)讓學(xué)生獨(dú)立完成： 1、課本23頁(yè)練習(xí)1、2 2、課本23頁(yè)3題的（給全體學(xué)生以示范性讓一個(gè)同學(xué)板書(shū)） 為向?qū)W生進(jìn)一步滲透數(shù)形結(jié)合的思想讓學(xué)生討論： 3、數(shù)軸上的點(diǎn)P與表示有理數(shù)3的點(diǎn)A距離是2， （1）試確定點(diǎn)P表示的有理數(shù)； （2）將A向右移動(dòng)2個(gè)單位到B點(diǎn)，點(diǎn)B表示的有理數(shù)是多少？ （3）再由B點(diǎn)向左移動(dòng)9個(gè)單位到C點(diǎn)，則C點(diǎn)表示的有理數(shù)是多少？ 先讓學(xué)生通過(guò)小組討論得出結(jié)果，通過(guò)以上練習(xí)使學(xué)生在掌握知識(shí)的基礎(chǔ)上達(dá)到靈活運(yùn)用，形成一定的能力。 （六）、歸納小結(jié)，強(qiáng)化思想： 根據(jù)學(xué)生的特點(diǎn)，師生共同小結(jié)： 1、為了鞏固本節(jié)課的教學(xué)重點(diǎn)提問(wèn):你知道什么是數(shù)軸嗎？你會(huì)畫(huà)數(shù)軸嗎？這節(jié)課你學(xué)會(huì)了用什么來(lái)表示有理數(shù)？ 2、數(shù)軸上，會(huì)不會(huì)有兩個(gè)點(diǎn)表示同一個(gè)有理數(shù)？會(huì)不會(huì)有一個(gè)點(diǎn)表示兩個(gè)不同的有理數(shù)？ 讓學(xué)生牢固掌握一個(gè)有理數(shù)只對(duì)應(yīng)數(shù)軸上的一個(gè)點(diǎn)，并能說(shuō)出數(shù)軸上已知點(diǎn)所表示的有理數(shù)。

一、教材分析：本節(jié)課選自北京師范大學(xué)教育出版社七年級(jí)上冊(cè)第五章第三節(jié)，是學(xué)生學(xué)習(xí)一元一次方程的含義，并掌握了解法后，通過(guò)分析圖形問(wèn)題中的數(shù)量關(guān)系，建立一元一次方程并用之解決實(shí)際問(wèn)題，是學(xué)生運(yùn)用數(shù)學(xué)知識(shí)解決生活中實(shí)際問(wèn)題中的典型素材，可提高學(xué)生解決問(wèn)題的能力，提高學(xué)習(xí)數(shù)學(xué)的興趣，形成學(xué)以致用的思想，認(rèn)識(shí)方程運(yùn)用模型的重要環(huán)節(jié)。二、學(xué)情分析：通過(guò)前幾節(jié)解方程的學(xué)習(xí)，學(xué)生已經(jīng)掌握了解、列方程的基本方法，在此過(guò)程中也初步掌握了運(yùn)用方程解決實(shí)際問(wèn)題的一般過(guò)程，基本會(huì)通過(guò)分析簡(jiǎn)單問(wèn)題中已知量與未知量的關(guān)系列出方程解應(yīng)用題，但學(xué)生在列方程解應(yīng)用題時(shí)常常會(huì)遇到從題設(shè)條件中找不到所依據(jù)的等量關(guān)系，或雖能找到等量關(guān)系，但不能列出方程這樣的問(wèn)題，因此，在教師的引導(dǎo)下，通過(guò)學(xué)生親自動(dòng)手制作模型，自主探索在模型變化過(guò)程中的等量關(guān)系，建立方程，從而將圖形問(wèn)題代數(shù)化。

按此規(guī)律，第n個(gè)式子是 。師生活動(dòng)：學(xué)生通過(guò)觀察，分析，歸納發(fā)現(xiàn)規(guī)律，并用含字母的式子表示一般結(jié)論。設(shè)計(jì)意圖：進(jìn)一步理解字母表示數(shù)的意義，理解用含有字母的數(shù)學(xué)式子表示實(shí)際問(wèn)題中的數(shù)量關(guān)系的簡(jiǎn)潔性、必要性和一般性。（四）鞏固提升問(wèn)題：你能給以上這些式子賦予新的含義嗎？師生活動(dòng)：教師舉例說(shuō)明比如：如果p表示我們班的人數(shù)，我們班80%的同學(xué)喜歡上數(shù)學(xué)課，那么0.8p 就可以表示我們班喜歡數(shù)學(xué)課的人數(shù)。學(xué)生思考、交流后發(fā)言五、練習(xí)檢測(cè)（1）5箱蘋(píng)果重m kg，每箱重 kg ；（2）一個(gè)數(shù)比a的 倍小5，則這個(gè)數(shù)為 ；（3）全校學(xué)生總數(shù)是x，其中女生占總數(shù)52%，則女生人數(shù)是 ，男生人數(shù)是 ；（4）某校前年購(gòu)買(mǎi)計(jì)算機(jī) x 臺(tái)，去年購(gòu)買(mǎi)數(shù)量是前年的2倍，今年購(gòu)買(mǎi)數(shù)量又是去年的2倍，則學(xué)校三年共購(gòu)買(mǎi)計(jì)算機(jī) 臺(tái)；（5）某班有a名學(xué)生，現(xiàn)把一批圖書(shū)分給全班學(xué)生閱讀，如果每人分4本，還缺25本，則這批圖書(shū)共 本；（6）一個(gè)兩位數(shù)，十位上的數(shù)字為a，個(gè)位上的數(shù)字b，則這個(gè)兩位數(shù)為 .師生活動(dòng)：學(xué)生板演，師生共同評(píng)價(jià)總結(jié)注意（5）帶分?jǐn)?shù)化假分?jǐn)?shù)設(shè)計(jì)意圖：進(jìn)一步提高用含有字母的式子表示實(shí)際問(wèn)題中的數(shù)量關(guān)系的能力。
北師大版初中七年級(jí)數(shù)學(xué)下冊(cè)用尺規(guī)作角說(shuō)課稿
活動(dòng)目的：通過(guò)兩個(gè)圖案設(shè)計(jì)，一個(gè)是讓學(xué)生獨(dú)立思考，借助于已經(jīng)學(xué)習(xí)的用尺規(guī)作線段和角來(lái)完成，對(duì)本節(jié)課的知識(shí)進(jìn)一步鞏固應(yīng)用；另一個(gè)是讓學(xué)生根據(jù)作圖步驟借助于尺規(guī)完成圖案，進(jìn)一步培養(yǎng)學(xué)生幾何語(yǔ)言表達(dá)能力，并積累尺規(guī)作圖的活動(dòng)經(jīng)驗(yàn)?；顒?dòng)注意事項(xiàng)：根據(jù)課堂時(shí)間安排，可靈活進(jìn)行處理，既可以作為本節(jié)課的實(shí)際應(yīng)用，也可以作為課下的聯(lián)系拓廣，從而使得不同層次的學(xué)生都學(xué)到有價(jià)值的數(shù)學(xué)。四、 教學(xué)設(shè)計(jì)反思1．利用現(xiàn)實(shí)情景引入新課，既能體現(xiàn)數(shù)學(xué)知識(shí)與客觀世界的良好結(jié)合，又能喚起學(xué)生的求知欲望和探求意識(shí)。而在了解基礎(chǔ)知識(shí)以后，將其進(jìn)行一定的升華，也能使學(xué)生明白學(xué)以致用的道理、體會(huì)知識(shí)的漸進(jìn)發(fā)展過(guò)程，增強(qiáng)思維能力的培養(yǎng)。同時(shí)，在整個(gè)探究過(guò)程中，怎樣團(tuán)結(jié)協(xié)作、如何共同尋找解題的突破口，也是學(xué)生逐步提高的一個(gè)途徑。

接下來(lái)學(xué)生類(lèi)比有理數(shù)中相關(guān)概念，體會(huì)到了實(shí)數(shù)范圍內(nèi)的相反數(shù)、倒數(shù)、絕對(duì)值的意義，并進(jìn)一步掌握了實(shí)數(shù)的相反數(shù)、倒數(shù)、絕對(duì)值等知識(shí)。學(xué)生類(lèi)比有理數(shù)中相關(guān)運(yùn)算，體會(huì)到了實(shí)數(shù)范圍內(nèi)的運(yùn)算及運(yùn)算律。并探討用數(shù)軸上的點(diǎn)來(lái)表示實(shí)數(shù)，將數(shù)和圖形聯(lián)系在一起，讓學(xué)生進(jìn)一步領(lǐng)會(huì)數(shù)形結(jié)合的思想，利用數(shù)軸也可以直觀地比較兩個(gè)實(shí)數(shù)的大小。然后通過(guò)相關(guān)練習(xí)，檢測(cè)學(xué)生對(duì)實(shí)數(shù)相關(guān)知識(shí)的掌握情況。最后學(xué)生交流，互相補(bǔ)充，完成本節(jié)知識(shí)的梳理。布置作業(yè)：所布置作業(yè)都是緊緊圍繞著“實(shí)數(shù)”的概念及運(yùn)用。設(shè)計(jì)選作題是為了給學(xué)有余力的學(xué)生留出自由發(fā)展的空間。五、關(guān)于板書(shū)設(shè)計(jì)我將板書(shū)設(shè)計(jì)為“提綱式”。這樣設(shè)計(jì)主要是力求重點(diǎn)突出，能加深學(xué)生對(duì)重點(diǎn)知識(shí)的理解和掌握，便于記憶。
