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”作用的評價史學(xué)界對“新政”作用的評價是仁者見仁、智者見智，但基本上有三種觀點，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，使美國人民擺脫了危機的困苦局面；其次，在缺少足夠的宏觀經(jīng)濟政策知識的時代，羅斯福所做的努力確實是開創(chuàng)性的；再次，羅斯?！靶抡遍_啟了美國以后歷屆政府實施國家干預(yù)政策的大門，成為緩解自由主義經(jīng)濟制度之弊病的一劑良方，并在實質(zhì)上加強了美國聯(lián)邦政府的權(quán)威；最后，在30年代資本主義世界經(jīng)濟危機的背景下，同日本、德國為轉(zhuǎn)嫁危機而發(fā)動戰(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。
