人教版高中歷史必修2戰(zhàn)后資本主義的新變化說課稿2篇
2.“里根經(jīng)濟(jì)學(xué)”和“撒切爾主義”20世紀(jì)70年代，世界資本主義經(jīng)濟(jì)發(fā)展進(jìn)入“滯脹”狀態(tài)后，各國政府紛紛尋找醫(yī)治這一新疾病的藥方，其中影響最大的是供應(yīng)學(xué)派和貨幣學(xué)派。1979年，撒切爾夫人上臺擔(dān)任英國首相，率先采納了貨幣學(xué)派的主張。1981年，里根擔(dān)任美國總統(tǒng)后，以供應(yīng)學(xué)派為依據(jù)，確立了自己政府的經(jīng)濟(jì)政策。由于兩人的經(jīng)濟(jì)政策都在一定程度上緩解了本國的經(jīng)濟(jì)危機(jī)，并有一套理論體系支撐，因此經(jīng)濟(jì)學(xué)家們分別稱之為“里根經(jīng)濟(jì)學(xué)”和“撒切爾主義”。實(shí)際上，“里根經(jīng)濟(jì)學(xué)”和“撒切爾主義”有許多相同之處，二者都提倡自由放任，強(qiáng)調(diào)市場調(diào)節(jié)作用，反對國家干預(yù)；二者都實(shí)行有利于富人的減稅政策，因此都曾被攻擊為“劫貧濟(jì)富”；二者都大力增加軍費(fèi)開支，用加大政府消費(fèi)來緩解危機(jī)。3.美國“新經(jīng)濟(jì)”戰(zhàn)后西方國家在凱恩斯主義指導(dǎo)下，暫時(shí)擺脫了三十年代那種嚴(yán)重的大蕭條局面，但由于長期實(shí)行擴(kuò)張性財(cái)政貨幣政策和對社會(huì)需求進(jìn)行管理的政策，各資本主義國家經(jīng)濟(jì)又出現(xiàn)新的危機(jī)，即“滯脹”（生產(chǎn)停滯和通貨膨脹），凱恩斯主義由此走向沒落。

共享實(shí)驗(yàn)收集的信息，分享實(shí)驗(yàn)探究的結(jié)論，體驗(yàn)收獲的樂趣。 小結(jié)拓展 這節(jié)課由大家感興趣的球類運(yùn)動(dòng)和彈弓游戲，提出了功與速度變化關(guān)系的問題，利用倍增思想解決測量對物體做功的問題，使用我們熟悉的器材設(shè)計(jì)了探究方案，并進(jìn)行實(shí)驗(yàn)探究，采用圖像法進(jìn)行數(shù)據(jù)處理，初步得出W∝V2的關(guān)系。在我們這節(jié)課探究以前，科學(xué)家就通過試驗(yàn)和理論的方法，已經(jīng)總結(jié)出了功與速度變化的定量關(guān)系。人類社會(huì)也在社會(huì)生活和生產(chǎn)的各個(gè)領(lǐng)域予以利用。比如，古代的戰(zhàn)爭武器拋石器、大型弓弩，以及現(xiàn)代飛機(jī)彈射系統(tǒng)、還有機(jī)器人行走等等，希望同學(xué)在今后的學(xué)習(xí)中注意留心生活中的物理和社會(huì)中的物理。 領(lǐng)會(huì)總結(jié)。培養(yǎng)概括總結(jié)的能力，進(jìn)一步鞏固、感悟、提升實(shí)驗(yàn)探究中獲得的思維能力及動(dòng)手能力。感悟社會(huì)中的物理，認(rèn)識物理學(xué)對科技進(jìn)步以及文化和社會(huì)發(fā)展的影響。 列舉學(xué)生知道的社會(huì)中做功使物體速度變化的例子，增強(qiáng)學(xué)生將物理知識應(yīng)用于生活和生產(chǎn)的意識，培養(yǎng)學(xué)生的社會(huì)參與意識和對社會(huì)負(fù)責(zé)任的態(tài)度。

什么因素可以阻止種群間基因交流呢？由此可引出隔離的概念。學(xué)生初步理解隔離的概念之后，可以安排學(xué)生討論隔離的各種可能的方式，教師歸納出隔離的類型。然后組織學(xué)生閱讀分析教材中的“資料分析”，組織討論“資料分析”中提出的幾個(gè)問題。最后教師應(yīng)強(qiáng)調(diào)，一般情況下，地理隔離是生殖隔離的先決條件，生殖隔離一旦形成，原來屬于一個(gè)物種的兩個(gè)種群，就成了兩個(gè)物種。關(guān)于“共同進(jìn)化與生物多樣性的形成”內(nèi)容的教學(xué)，可以學(xué)生自學(xué)為基礎(chǔ)，教師提出一些具有啟發(fā)性的問題，師生共同歸納總結(jié)的方式推進(jìn)教學(xué)過程。使學(xué)生理解共同進(jìn)化的含義，無機(jī)環(huán)境的變化、無機(jī)環(huán)境的復(fù)雜化和多樣化、有性生殖的出現(xiàn)和生態(tài)系統(tǒng)結(jié)構(gòu)的復(fù)雜化和多樣化對生物多樣性形成的作用。最后，組織學(xué)生討論生物進(jìn)化理論在發(fā)展。

新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學(xué)設(shè)計(jì)
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.
