人教版高中歷史必修2大眾傳媒的變遷說課稿
教學(xué)內(nèi)容與分析本課內(nèi)容是大眾傳媒的變遷，首先解題，了解什么是大眾傳媒。大眾傳媒就是傳播大眾信息的媒體，進(jìn)入近代社會(huì)以來，人與人之間的聯(lián)系變得越來越密切，社會(huì)化程度大大加深，需要有一種大眾化、傳播速度快、傳播范圍廣的媒介作為人與人之間進(jìn)行信息溝通的渠道，人類社會(huì)的傳媒手段應(yīng)運(yùn)而生，可由學(xué)生總結(jié)出有哪些主要的方式。報(bào)刊、影視、廣播，這三種大眾傳播媒體的依次出現(xiàn)，給人們的生活方式帶來了巨大的變化，被稱為三大媒介。由于互聯(lián)網(wǎng)同報(bào)紙、廣播和電視三大媒介一樣，具有傳播信息的功能，所以被稱為“第四媒介”，即“網(wǎng)絡(luò)媒介”。通過本節(jié)課的學(xué)習(xí)使學(xué)生了解中國近代社會(huì)生活的變化，體會(huì)歷史和時(shí)代發(fā)展的必然性，能夠站在發(fā)展的角度、用歷史的眼光思考問題。
人教版高中生物必修2染色體變異說課稿
四、說教學(xué)程序（一）.溫故知新、導(dǎo)入新課復(fù)習(xí)提問:基因突變導(dǎo)致生物變異的原因是什么?回答:基因突變是基因結(jié)構(gòu)發(fā)生改變，從而使遺傳信息改變，使蛋白質(zhì)結(jié)構(gòu)改變、生物性狀改變，即生物發(fā)生了變異。那么，基因是什么?它和染色體又有何關(guān)系?回答:基因是有遺傳效應(yīng)的DNA片斷，染色體是DNA的載體，基因在染色體上呈線形排列。引出新知:對(duì)于一個(gè)生物體來說，正常情況下，其染色體的結(jié)構(gòu)和數(shù)量都是穩(wěn)定的。但在自然條件或人為因素的影響下，染色體的結(jié)構(gòu)和數(shù)量均會(huì)發(fā)生改變，從而導(dǎo)致生物性狀的改變，這就屬于染色體變異。（二）.把握重點(diǎn)、突破難點(diǎn)重點(diǎn)的把握：1、染色體結(jié)構(gòu)的變異播放影片:貓叫綜合征幼兒。讓學(xué)生觀察: 患兒哭聲輕、音調(diào)高，很像貓叫。教師補(bǔ)充: 患兒的征狀---兩眼較低、耳位低下，存在著嚴(yán)重的智力障礙。闡述病因---染色體片段缺失

一 減數(shù)分裂高一生物減數(shù)分裂說課稿各位評(píng)委、老師：大家好，我今天說課的題目是高中生物必修2第二章第一節(jié)〈〈減數(shù)分裂與受精作用〉〉第一部分減數(shù)分裂第一課時(shí)精子形成過程。接下來我就從以下幾個(gè)方面來說說這一節(jié)課。一、說教材1．教材地位和作用《減數(shù)分裂》這一部分內(nèi)容不僅是第二章的重點(diǎn)內(nèi)容，也是整本書的重點(diǎn)內(nèi)容之一。它以必修一學(xué)過的細(xì)胞學(xué)知識(shí)、染色體知識(shí)、有絲分裂知識(shí)和初中生殖種類知識(shí)為基礎(chǔ)。通過學(xué)習(xí)，使學(xué)生全面認(rèn)識(shí)細(xì)胞分裂的種類、實(shí)質(zhì)和意義，為后面學(xué)習(xí)遺傳和變異，生物的進(jìn)化奠定細(xì)胞學(xué)基礎(chǔ)。2．教學(xué)目標(biāo)（1）知識(shí)目標(biāo)：掌握減數(shù)分裂的概念和精子的形成過程；理解減數(shù)分裂和受精作用的意義。（2）能力目標(biāo)：通過觀察減數(shù)分裂過程中染色體的行為變化，培養(yǎng)學(xué)生識(shí)圖、繪圖能力以及比較分析和歸納總結(jié)的能力。
人教版高中歷史必修3現(xiàn)代中國教育的發(fā)展說課稿
一、教材分析下面我來談一談對(duì)教材的認(rèn)識(shí)：主要從教材的地位和作用、以及在此基礎(chǔ)上確立的教學(xué)目標(biāo)、教學(xué)重難點(diǎn)這三個(gè)方面來談。首先，來談教材的地位和作用：本課教材內(nèi)容主要從三個(gè)方面向?qū)W生介紹了現(xiàn)代中國教育的發(fā)展?fàn)顩r和趨勢(shì)：人民教育的奠基、動(dòng)亂中的教育和教育的復(fù)興，全面講述了新中國教育的三個(gè)階段。本課是文化史中中國史部分的最后一課， 也是必修三冊(cè)書中唯一涉及教育的一課。而教育是思想文化史中的重要組成部分，江澤民同志在談到教育的時(shí)候曾經(jīng)說過，“百年大計(jì)，教育為本。教育為本，在于育人”。教育是關(guān)系國計(jì)民生的大事。學(xué)生通過學(xué)習(xí)新中國教育發(fā)展的史實(shí)，理解“科教興國”、“國運(yùn)興衰，系于教育”的深刻含義。最終由此激發(fā)學(xué)生樹立“知識(shí)改變命運(yùn)、讀書成就人生”的信念，樹立勤奮學(xué)習(xí)、成人成才、報(bào)效祖國、服務(wù)社會(huì)的崇高理想。故本課的教學(xué)有極大的現(xiàn)實(shí)意義。談完了教材的地位和作用，我再分析一下教學(xué)目標(biāo)：
