人教版高中歷史必修2開辟新航路教案
材料五航路開辟后，東方香料輸入歐洲的總量較中古之時(shí)猛增30倍，而胡椒、丁香等在印度購入和在英國賣出的差價(jià)亦高達(dá)10至29倍，其他貨物的獲利同樣驚人。這一時(shí)期，新的商品不斷涌現(xiàn)，特別值得注意的是美洲的特產(chǎn)——玉米、馬鈴薯、煙草、可可等——被傳播到歐亞大陸。這時(shí)，世界性的對外貿(mào)易主要通過大西洋，地中海與意大利皆告衰落，而沿大洋的英、荷等漸居中心。到17世紀(jì)時(shí)，英國的倫敦與荷蘭的阿姆斯特丹成為世界貿(mào)易中心。問題4：材料五表明，新航路開辟后對世界貿(mào)易產(chǎn)生了哪些重大影響？答案4：結(jié)束了世界相對孤立狀態(tài)；各地文明開始會(huì)合交流，日益連成一個(gè)整體；歐洲商人直接同世界各地建立商業(yè)聯(lián)系；促進(jìn)不同國家和貿(mào)易的發(fā)展，促進(jìn)世界市場雛形開始出現(xiàn)。
人教版高中歷史必修2羅斯福新政教案
【教學(xué)參考】對“新政”作用的評價(jià)史學(xué)界對“新政”作用的評價(jià)是仁者見仁、智者見智，但基本上有三種觀點(diǎn)，即“功大于過論”、“過大于功論”和“功過參半論”。持“功大于過論”者認(rèn)為“新政”在美國歷史上基本上是一種進(jìn)步現(xiàn)象，首先，“新政”挽救了危機(jī)，使美國人民擺脫了危機(jī)的困苦局面；其次，在缺少足夠的宏觀經(jīng)濟(jì)政策知識(shí)的時(shí)代，羅斯福所做的努力確實(shí)是開創(chuàng)性的；再次，羅斯福“新政”開啟了美國以后歷屆政府實(shí)施國家干預(yù)政策的大門，成為緩解自由主義經(jīng)濟(jì)制度之弊病的一劑良方，并在實(shí)質(zhì)上加強(qiáng)了美國聯(lián)邦政府的權(quán)威；最后，在30年代資本主義世界經(jīng)濟(jì)危機(jī)的背景下，同日本、德國為轉(zhuǎn)嫁危機(jī)而發(fā)動(dòng)戰(zhàn)爭的策略相比，“新政”無疑代表了一種進(jìn)步、民主的解救危機(jī)方式。持“過大于功論”者認(rèn)為“新政”未能使美國走出蕭條、步入繁榮。

師：希望大家開動(dòng)腦筋，大膽猜想，看誰能根據(jù)自己已有的生活經(jīng)驗(yàn)和知識(shí)經(jīng)驗(yàn)，發(fā)現(xiàn)小數(shù)加減法計(jì)算的方法，并說明其中的道理。出示圖片。師：從圖中了解到什么信息？（學(xué)生自由介紹）師：這些小數(shù)都認(rèn)識(shí)嗎？誰來談?wù)剬@些小數(shù)的認(rèn)識(shí)。提問：小數(shù)點(diǎn)后面的“5”表示什么？小數(shù)點(diǎn)前面的2表示什么意思？3.師：根據(jù)這些信息你能提出哪些數(shù)學(xué)問題？根據(jù)學(xué)生回答教師板書解決問題的算式。選擇一個(gè)問題研究。（三）探究算理1.嘗試計(jì)算并說明理由。（選擇12.5+3.6＝板書）學(xué)生先嘗試用自己的方法解決，把不同的方法板演在黑板上。2.學(xué)生反饋、組織評價(jià)。先讓生自己說計(jì)算過程和想法，并給予點(diǎn)評，再重點(diǎn)講解筆算的方法和算理。3.探究小數(shù)的減法。師：根據(jù)小數(shù)加法的經(jīng)驗(yàn)，減法能獨(dú)立解決嗎？學(xué)生獨(dú)立解決問題。反饋時(shí)展示學(xué)生不同的計(jì)算方法。評價(jià)時(shí)注重引導(dǎo)學(xué)生說說是怎樣想的，引導(dǎo)學(xué)生說清算理。強(qiáng)調(diào)整數(shù)部分“0”的處理。

一、說教材：本節(jié)課是在理解和掌握了五條運(yùn)算定律的基礎(chǔ)上進(jìn)一步學(xué)習(xí)整數(shù)運(yùn)算中的一些簡便計(jì)算。這部分內(nèi)容主要安排了五道例題。我主要教學(xué)的是例1和例2，討論加減法運(yùn)算中常用的簡便計(jì)算。例1主要著眼于通過不同解法的比較，使學(xué)生認(rèn)識(shí)一個(gè)數(shù)連續(xù)減去兩個(gè)數(shù)可以改為減去這兩個(gè)數(shù)的和。例2主要是加減計(jì)算的靈活應(yīng)用，通過典型的、緊密聯(lián)系生活，引導(dǎo)學(xué)生根據(jù)運(yùn)算特點(diǎn)和數(shù)據(jù)特點(diǎn)，靈活選用合理簡便的計(jì)算方法。本節(jié)教材最大的特點(diǎn)是：將簡便計(jì)算的討論與實(shí)際問題的解決有機(jī)地結(jié)合起來，使問題解決策略的多樣化與計(jì)算方法的多樣化融為一體。根據(jù)這一特點(diǎn)，我制定本節(jié)課的教學(xué)目標(biāo)有以下幾點(diǎn)：1、讓學(xué)生在解決問題中理解連減的簡便計(jì)算方法，體驗(yàn)計(jì)算方法的多樣化。2、使學(xué)生感受數(shù)學(xué)與現(xiàn)實(shí)生活中的聯(lián)系，培養(yǎng)學(xué)生根據(jù)具體情況選擇算法的意識(shí)與能力，發(fā)展思維性。
