    人教版高中歷史必修3“罷黜百家獨尊儒術(shù)”說課稿2篇

    1、漢武帝尊儒的措施:(1)政治方面:起用很多儒學(xué)家參與國家大政。他規(guī)定,地方定期選出孝子、廉吏當(dāng)中央任官,甚至還擢升平民、儒士為相。這明顯擴大了官員的隊伍,提高了官員的文化素質(zhì),鞏固了封建統(tǒng)治基礎(chǔ),成為漢武帝文治武功的重要組成部分。也給后世封建王朝在用人方式方法上面提供了寶貴的借鑒和啟迪。(2)思想方面:采納董仲舒的建議,“罷黜百家 獨尊儒術(shù)”(3)教育方面:儒家經(jīng)典“五經(jīng)”為國家規(guī)定的教科書。興辦太學(xué)和設(shè)立地方學(xué)校進行儒學(xué)教育。公元前136年,漢武帝正式規(guī)定《詩》、《書》、《禮》、《易》、《春秋》為“五經(jīng)”;前124年,又在長安興辦太學(xué),規(guī)定太學(xué)生員為博士弟子,一律由儒家五經(jīng)博士負責(zé)教授,學(xué)完經(jīng)考試合格后即可到政府任官。這是封建國家利用政權(quán)的力量興辦教育、提倡儒學(xué),其必然對整個社會的教育事業(yè)有一定的導(dǎo)向作用。

    一、教材地位《音樂與影視藝術(shù)》是人教版高中歷史必修(III)第八專題中的第三節(jié)內(nèi)容。音樂、影視藝術(shù)屬于意識形態(tài)范疇,是當(dāng)時政治、經(jīng)濟的反映,是社會進步的產(chǎn)物。19世紀(jì)以來的音樂與影視藝術(shù)糅合了近代科學(xué)技術(shù)的元素,直接引領(lǐng)著文明發(fā)展趨勢和社會風(fēng)尚,滿足人們不同層次的審美需要和精神追求。音樂、影視藝術(shù)在人類日常生活中無處不在,已經(jīng)成為人們?nèi)粘I钪械闹匾M成部分,所以具有重要地位。本課分三個部分介紹了19世紀(jì)和20世紀(jì)音樂的發(fā)展與變化以及影視藝術(shù)的產(chǎn)生發(fā)展。下面我就談?wù)剬@節(jié)課的教學(xué)思路。二、教材分析1、課標(biāo)要求課標(biāo)的要求是:列舉19世紀(jì)以來有代表性的音樂作品,理解這些音樂作品的時代性和民族性。了解影視藝術(shù)產(chǎn)生與發(fā)展的歷程,認識其對社會生活的影響。2、教學(xué)目標(biāo)根據(jù)新課標(biāo)、教材內(nèi)容、學(xué)生實際,確定教學(xué)目標(biāo)如下:(1)知識與能力:①列舉19世紀(jì)以來有代表性的音樂作品,理解這些音樂作品的時代性和民族性。
