    人教版高中生物必修3第四章第二節(jié)《種群數(shù)量的變化》說課稿

    4、種群數(shù)量變化的其他類型我結(jié)合“種群數(shù)量下降”這個知識點對學(xué)生進行寓教?,F(xiàn)今的自然界,許多野生生物種群的數(shù)量都在下降,為什么呢?我提供了世界人口近2000年的種群增長曲線,一切都在不言而喻中?,F(xiàn)今社會的主題是呼吁建立和諧社會,作為生物老師,我想它不應(yīng)該僅僅指人與人之間的和諧,也不應(yīng)該僅僅指人與社會之間的和諧,它更應(yīng)該昭示著人與自然之間的和諧,人類只有學(xué)會與自然和諧相處,才能在生物圈中享受最大的幸福。6、小結(jié)課程在實驗的大背景下展開,也在實驗的背景中結(jié)束,這里可以呈現(xiàn)出一個完整的探究思路。同時,學(xué)生思考如何實現(xiàn)多種預(yù)期過程,相當(dāng)于對本課進行小結(jié)。五、效果預(yù)測課堂上選取的內(nèi)容基于學(xué)生的生活體驗,創(chuàng)設(shè)的情境能激發(fā)學(xué)生的興趣,設(shè)置的問題符合學(xué)生的認(rèn)知水平,有助于學(xué)生能力的提高,教學(xué)目標(biāo)可以基本實現(xiàn)。

    二、君主專制的演進(即中央政治制度的演變)通過地方政治制度演變的學(xué)習(xí),掌握方法以后,以學(xué)生歸納整理基本線索為主,教師適當(dāng)點撥,注意糾錯。1. 漢承秦制,又有所變化。教師點撥強調(diào)繼承與發(fā)展兩個方面。創(chuàng)設(shè)情景:同學(xué)們看了電視連續(xù)劇《漢武大帝》后,知道漢武帝劉徹在繼位之后,就急于對西漢王朝的政治制度進行改革。那么,西漢初期中央政治制度的基本框架是怎樣的呢?漢武帝為什么要對它進行改革呢?改革后的西漢中央集權(quán)制度又是怎樣的呢?請大家議一議,想一想。主干知識:西漢初期的中央政治制度的最大特點是“漢承秦制”。具體表現(xiàn)在兩個方面:一是繼續(xù)實行皇帝制度,維護皇權(quán),這一做法也為后來各王朝所沿用;二是在中央設(shè)立三公,分別掌管行政、監(jiān)察和軍事。到漢武帝時,“中朝”成為西漢重要的中央決策機構(gòu),尚書令的權(quán)力日益重要,以丞相為首的三公九卿的權(quán)力被削弱,演化為執(zhí)行機構(gòu)。到了東漢光武帝時,進一步剝奪三公權(quán)限,擴大尚書的權(quán)力。

    談到這,如果有人會說這僅僅是在于我個人與戰(zhàn)場之上,戰(zhàn)場之下另當(dāng)別論,那么,他完全錯了。在我小學(xué)四年級的語文課上有兩個人發(fā)言積極,一個姓黃,一個姓康,黃同學(xué)發(fā)言比康同學(xué)更積極,班上的同學(xué)常以為黃同學(xué)是個了不得的人物,后來,教語文的吳老師曾悄悄地告訴我:班上真正厲害的是康x,那黃x沒什么,說的全是“一點通”上的,照搬不誤。說到這,我還得厚著臉皮自夸一下,在四年級時,我和康同學(xué)是同坐,一次,老師叫我們對一片課文(好象是寫黃繼光舍身炸暗堡)的一個段落提問題時,我悄悄地對康同學(xué)說了一個問題,康同學(xué)對我說:“你站起來說嘛?!眱?nèi)向的我遙遙頭,康同學(xué)便站舉手,并起來將我的問題大聲地說了出來,結(jié)果老師說:“恩,康x的問題提得很好?!?/p>

    Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times. The first and listening is extensive listening and the second and third listening is intensive listening. In the first time, They are required to listen a material including Part 1 and Part 2 and choose the best summary of the listening text. After they choose the right answer, They also need work in group to explain what is wrong with the others. Then I will make a conclusion that we should pay attention to the first paragraph and last paragraph and some keys to get the main idea. By doing this, their capacity of generalization will have a great improvement.Before the second listening, I will ask students to scan the blank on the power point quickly and ask them to note down some key words .Then ask them to listen to the Part 1again and fill the first column of the chart. Maybe some students just show the ideas of these three scientists an still can’t catch their development of gravity. Therefore, I will ask them to listen to Part 2 again and fill in the rest. After finish the listening, I will give them ten minutes to discuss with their partner. I will also guidethem to improve their answers when they discuss with others.

    陸王心學(xué)與程朱理學(xué)相比有何異同?生 不同點: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: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。
