一、 教材分析1、 教材地位和作用《當(dāng)今世界的經(jīng)濟(jì)區(qū)域集團(tuán)化》是人教版《歷史②》(必修)第八單元第二課的內(nèi)容。主要圍繞戰(zhàn)后世界經(jīng)濟(jì)中出現(xiàn)的經(jīng)濟(jì)區(qū)域集團(tuán)化的趨勢(shì),重點(diǎn)介紹了對(duì)世界經(jīng)濟(jì)影響最大的三大區(qū)域集團(tuán):歐洲聯(lián)盟、北美自由貿(mào)易區(qū)和亞太經(jīng)濟(jì)合作組織。從內(nèi)容上既銜接了70年代布雷頓森林體系瓦解后80年代出現(xiàn)的經(jīng)濟(jì)區(qū)域集團(tuán)化的趨勢(shì),又啟示了這種趨勢(shì)是經(jīng)濟(jì)全球化趨勢(shì)的一部分,提出了下節(jié)課的主題。具有承上啟下的作用。2、 教學(xué)目標(biāo)根據(jù)高中新課程標(biāo)準(zhǔn)和知識(shí)與能力、過程與方法、情感態(tài)度價(jià)值觀三者統(tǒng)一的要求,我將本節(jié)課的教學(xué)目標(biāo)定為以下的三大方面:1) 知識(shí)與能力:能夠讓學(xué)生理解三大區(qū)域經(jīng)濟(jì)集團(tuán)建立的史實(shí),認(rèn)識(shí)三大區(qū)域經(jīng)濟(jì)組織在世界經(jīng)濟(jì)全球化進(jìn)程中的影響和作用,增強(qiáng)學(xué)生辨證地觀察、分析歷史問題的能力。

一、說教材《質(zhì)點(diǎn) 參考系和坐標(biāo)系》是人教版普通高中物理必修一第一章第一課的內(nèi)容。本節(jié)課主要介紹了質(zhì)點(diǎn)、參考系、坐標(biāo)系的基本概念。通過本節(jié)課的學(xué)習(xí)為進(jìn)一步學(xué)習(xí)后續(xù)課程起到了鋪墊的作用。根據(jù)上述教材的結(jié)構(gòu)和內(nèi)容分析,又考慮到高一年級(jí)學(xué)生的認(rèn)知結(jié)構(gòu)及其心理特征,我制定了以下三維教學(xué)目標(biāo):1、知識(shí)與技能:知道質(zhì)點(diǎn)的概念及條件;知道參考系的概念及作用;掌握坐標(biāo)系的簡(jiǎn)單應(yīng)用。2、過程與方法:促進(jìn)學(xué)生自主學(xué)習(xí),讓學(xué)生積極參與、樂于探究、勇于實(shí)驗(yàn)、勤于思考,培養(yǎng)學(xué)生的科學(xué)探究能力。3、情感態(tài)度與價(jià)值觀:通過質(zhì)點(diǎn) 參考系和坐標(biāo)系的學(xué)習(xí),使學(xué)生了解生活與物理的關(guān)系,讓學(xué)生學(xué)會(huì)用科學(xué)的思維去看待事物。根據(jù)普通高中物理課程標(biāo)準(zhǔn),并在吃透教材的基礎(chǔ)上,我確定了以下教學(xué)重點(diǎn)和難點(diǎn):教學(xué)重點(diǎn):質(zhì)點(diǎn)概念的建立。只有掌握了這一點(diǎn)才能更加準(zhǔn)確的理解和掌握后續(xù)教材的相關(guān)內(nèi)容。

一、說教材的地位和作用《細(xì)胞中的元素和化合物》是人教版教材生物必修一第二章第1節(jié)內(nèi)容。《細(xì)胞中的元素和化合物》這一節(jié),首先在節(jié)的引言中,明確指出自然界的生物體中的元素是生物有選擇地從無機(jī)自然界中獲得的,沒有一種元素是細(xì)胞特有的。但細(xì)胞與非生物相比,各元素的含量又大不相同。說明生物界與非生物界具有統(tǒng)一性和差異性。這部分內(nèi)容較為淺顯,但是結(jié)論非常重要,對(duì)于學(xué)生了解生物的物質(zhì)性具有重要意義二、說教學(xué)目標(biāo)根據(jù)本教材的結(jié)構(gòu)和內(nèi)容分析,結(jié)合著高一年級(jí)學(xué)生的認(rèn)知結(jié)構(gòu)及心理特征,我制定了以下的教學(xué)目標(biāo):1、知識(shí)目標(biāo):知道組成細(xì)胞的主要元素;知道為什么碳元素是構(gòu)成細(xì)胞的基本元素2、能力目標(biāo):學(xué)會(huì)檢測(cè)生物組織中的糖類、脂肪和蛋白質(zhì)的方法。(1)通過對(duì)C元素的分析,說明有機(jī)化合物形成的可能性及必然性,初步培養(yǎng)學(xué)生跨學(xué)科綜合分析問題的能力。(2)通過對(duì)組成細(xì)胞中的元素的百分比的分析,通過對(duì)不同化合物的質(zhì)量分?jǐn)?shù)的學(xué)習(xí),培養(yǎng)學(xué)生理解、思考和分析問題的能力。

(一)教材的地位與作用該節(jié)教材以水資源作為案例,說明在不同的生產(chǎn)力條件下,水資源的數(shù)量和質(zhì)量對(duì)人類生存和發(fā)展的意義。教材首先從水資源的概念入手,介紹世界和我國(guó)的水資源的狀況,接著辨證論述水資源與人類社會(huì)之間的相互影響,緊扣水資源的數(shù)量和質(zhì)量隨時(shí)空變換,對(duì)人類生存與發(fā)展的影響,科技對(duì)水資源的利用也發(fā)揮了一定作用,但是隨著人口持續(xù)增長(zhǎng)、經(jīng)濟(jì)高速發(fā)展,不能從根本上解決水資源的短缺,因此必須要從開源和節(jié)流兩方面合理利用水資源。此部分內(nèi)容穿插圖片和實(shí)例,特別是通過以色列水資源的利用和咸海面積縮小的兩個(gè)案例,讓學(xué)生明確和鞏固以上觀點(diǎn)。(二)教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo):1.通過讀圖分析數(shù)據(jù)明了水資源的概念。2.結(jié)合事例了解水資源對(duì)人類發(fā)展的意義。3.通過分析圖表資料認(rèn)識(shí)全球和我國(guó)的水資源狀況,提高讀圖分析能力。4.以我國(guó)為例,針對(duì)我國(guó)的水資源利用狀況,結(jié)合所學(xué),學(xué)生合作探究我國(guó)水資源合理利用方案,進(jìn)而歸納基本的水資源可持續(xù)利用策略和措施。

① 實(shí)驗(yàn)設(shè)計(jì)將學(xué)生分組,利用桌上的器材進(jìn)行探究(幻燈片展示)這個(gè)實(shí)驗(yàn)難度較大,為了降低難度,為實(shí)驗(yàn)探究鋪下第二臺(tái)階,要求學(xué)生先分小組討論以下問題(幻燈片展示)有些學(xué)生可能不知如何下手,我會(huì)要求學(xué)生先閱讀課本中的實(shí)驗(yàn)描述從中得到一點(diǎn)提示,再讓一兩個(gè)小組同學(xué)回答,這樣既體現(xiàn)了學(xué)生學(xué)習(xí)的主體性又可提高學(xué)生自主思考和語言表達(dá)能力,之后我再進(jìn)行補(bǔ)充完善(幻燈片展示答案),并用幻燈片把實(shí)驗(yàn)步驟展示出來,在學(xué)生實(shí)驗(yàn)過程一直保留,使學(xué)生能朝正確的方向進(jìn)行猜想和操作,為實(shí)驗(yàn)探究鋪下第三個(gè)臺(tái)階。② 實(shí)施探究在學(xué)生分組進(jìn)行探究過程,教師巡視解惑,隨時(shí)觀察學(xué)生情況,解答學(xué)生提出的問題,還可用自言自語方式提示應(yīng)注意的一些問題,如儀器的正確使用,操作的規(guī)范等,幫助學(xué)生盡量在規(guī)定時(shí)間內(nèi)順利完成實(shí)驗(yàn)。

四、教學(xué)過程1.導(dǎo)入新課(2分鐘)出示中非合作論壇暨第3屆部長(zhǎng)級(jí)會(huì)議圖片。用時(shí)事引起學(xué)生注意,設(shè)問,“55年前,亞洲與非洲有哪一次跨越印度洋的握手”,提示答案“萬隆亞非會(huì)議”,給出答案導(dǎo)入新課2.外交環(huán)境:學(xué)生閱讀,教師分析。(3分鐘)3.外交方針之一:獨(dú)立自主的和平外交方針(5分鐘) 出示材料:《共同綱領(lǐng)》引文。學(xué)生、閱讀、提煉除新中國(guó)奉行獨(dú)立自主的外交政策。進(jìn)而由學(xué)生分析另起爐灶、打掃干凈屋子再請(qǐng)客和一邊倒。培養(yǎng)學(xué)生分析材料、利用材料的能力過度:新中國(guó)作出一邊倒大的積極主動(dòng)態(tài)勢(shì),社會(huì)主義陣營(yíng)的兄弟們也立刻作出了積極回應(yīng)。1949年10月2日,中蘇建立了外交關(guān)系。4.外交建樹之一:同蘇聯(lián)等17個(gè)國(guó)家建立外交關(guān)系(3分鐘)出示毛澤東訪問蘇聯(lián)等圖片和第一批建交的17個(gè)國(guó)家名字

(設(shè)計(jì)意圖: 通過這兩個(gè)問題探究的形式可以了解學(xué)生對(duì)二、干旱為主的自然特征這一知識(shí)點(diǎn)的掌握情況,隨堂練習(xí)有利于鞏固強(qiáng)化學(xué)生的條例性知識(shí)。)三、荒漠化的成因1、自然因素:干旱、氣候異常2、人為因素:(是荒漠化發(fā)生、發(fā)展的決定因素)自然原因啟發(fā)學(xué)生利用已經(jīng)學(xué)過的知識(shí)(干旱為主的自然特征)和給出的PPT資料來進(jìn)行分析。人為原因以其危害結(jié)果用圖表和圖片的形式展示,使學(xué)生認(rèn)識(shí)到人為因素是導(dǎo)致荒漠化最主要的因素。(設(shè)計(jì)意圖:通過分析自然因素提供學(xué)生分析一區(qū)域環(huán)境建設(shè)的自然基礎(chǔ)條件,而這也是較難的一點(diǎn),再者,通過分析人為原因,是學(xué)生樹立區(qū)域生態(tài)環(huán)境保護(hù)意識(shí)。)四、布置作業(yè):書本課本20—22的活動(dòng)—— 非洲薩赫勒地區(qū)荒漠化的自然、社會(huì)經(jīng)濟(jì)

師我國(guó)河流眾多,長(zhǎng)江流域、黃河流域、珠江流域等正在繼續(xù)開發(fā),出示“長(zhǎng)江流域示意圖”,請(qǐng)同學(xué)們借鑒今天所學(xué)的分析方法,分析長(zhǎng)江流域發(fā)展的自然地理?xiàng)l件。(學(xué)生相互交流、討論)生略。師長(zhǎng)江干流全長(zhǎng)6300余千米,發(fā)源于青藏高原,流經(jīng)青、藏、滇、川、渝、鄂、湘、贛、皖、蘇、滬,奔入東海。水域遼闊,總面積達(dá)180萬平方千米,流經(jīng)我國(guó)半壁河山。水量汪洋壯闊,多年平均入海近10000億立方米。流域內(nèi)總?cè)丝凇⒏馗骷s占全國(guó)的35%,工農(nóng)業(yè)總產(chǎn)值占全國(guó)的40%~50%,歷來是中華民族繁衍的沃土。流域經(jīng)過我國(guó)三大階梯,流經(jīng)青藏高原、橫斷山脈、四川盆地、云貴高原、長(zhǎng)江中下游平原等地形區(qū)。流域內(nèi)水系發(fā)達(dá)、眾多,以亞熱帶季風(fēng)氣候?yàn)橹?,氣候溫暖濕?rùn),降水量豐富,河流水量大,水能資源、森林資源、礦產(chǎn)資源豐富,長(zhǎng)江干流自古以來就是我國(guó)東西航運(yùn)的大動(dòng)脈,溝通內(nèi)地和沿海的廣大地區(qū),干支流通航里程約占全國(guó)內(nèi)河航道總里程的2/3,形成了一個(gè)縱橫廣闊的水運(yùn)網(wǎng),被譽(yù)為“黃金水道”。

Let them understand the attitudes of Wu Yue and Justin in the conversation.How does Wu Yue feel about Chinese minority cultures?What does Justin think of the Miao and Dong cultures?How do you know that?2.learn functional items that express concerns.Ask students to focus on the expressions listed in activity. 3.And try to analyze the meaning they convey, including praise (Super!).Agree (Exactly!)"(You're kidding.!)Tell me more about it. Tell me more about it.For example, "Yeah Sure." "Definitely!" "Certainly!" "No kidding!" "No wonder!" and so on.4.Ask the students to have conversations in small groups, acting as Jsim and his friends.Justin shares his travels in Guizhou with friends and his thoughts;Justin's friends should give appropriate feedback, express their interest in relevant information, and ask for information when necessary.In order to enrich the dialogue, teachers can expand and supplement the introduction of Miao, dong, Lusheng and Dong Dage.After the group practice, the teacher can choose several groups of students to show, and let the rest of the students listen carefully, after listening to the best performance of the group, and give at least two reasons.

一、人類遺傳病1.概念2.分類(1)單基因遺傳病(2)多基因遺傳病(3)染色體異常遺傳?、僭颌陬愋?遺傳病的特點(diǎn)4.遺傳病對(duì)人類的危害八、說布置作業(yè)在作業(yè)的布置中,我嚴(yán)格遵循“重質(zhì)量、輕負(fù)擔(dān)”的指導(dǎo)思想。第一題主要是為了幫助學(xué)生及時(shí)糾正原有的對(duì)知識(shí)的錯(cuò)誤理解或片面認(rèn)識(shí),培養(yǎng)學(xué)生的解題技巧和技能。所以我選用了該題。同時(shí)想借助該題培養(yǎng)學(xué)生對(duì)問題的科學(xué)的思維方法和探究的精神。幫助學(xué)生提高對(duì)信息技術(shù)運(yùn)用的熟練程度,發(fā)展學(xué)生的信息素養(yǎng)。附作業(yè):1、連線題,請(qǐng)同學(xué)們連線指出下列遺傳各屬于何種類型?(1)苯丙酮尿病 A、單基因遺傳?。?)21三體綜合征(3)抗維生素D佝僂病 B、多基因遺傳病(4)軟骨發(fā)育不全(5)青少年型糖尿病 C、常染色體病2、以生物小組為單位進(jìn)行人類遺傳病的調(diào)查。

“深入探究,把握主旨”這一步則是解決教學(xué)的重點(diǎn)難點(diǎn),這里涉及到課文的深層意蘊(yùn),學(xué)生理解有難度,教師在通過問題引領(lǐng)學(xué)生探討的基礎(chǔ)上,還要適時(shí)啟發(fā)、點(diǎn)撥,因?yàn)榻虒W(xué)時(shí)間有限,讓學(xué)生漫無邊際的討論,可能難以完成預(yù)定的教學(xué)任務(wù),會(huì)使教學(xué)過程不完整。至于本文的寫作特點(diǎn)的教學(xué)視時(shí)間而定,有時(shí)間可以讓學(xué)生說一說,沒有時(shí)間用小黑板出示一下,讓學(xué)生了解就行,如果時(shí)間不夠,甚至可以不講。第三階段是“延伸練習(xí),鞏固提高”。

(2).教學(xué)手段為了使我根據(jù)教材而設(shè)計(jì)的三個(gè)教學(xué)目標(biāo)以及重點(diǎn)難點(diǎn)得以的突出和突破,達(dá)到最大化的展示境界,同時(shí)也為了配合以上我選擇的四種教法得以完滿實(shí)現(xiàn),我決定采用“多媒體”教學(xué)手段進(jìn)行全程教學(xué)。利用電腦的信息容量大,操作簡(jiǎn)便等優(yōu)點(diǎn),形象生動(dòng)的直觀展示教學(xué)內(nèi)容,不但提高學(xué)習(xí)效率和質(zhì)量,而且容易激發(fā)學(xué)生的學(xué)習(xí)興趣和調(diào)動(dòng)學(xué)習(xí)的積極性。四、說學(xué)法我為學(xué)生設(shè)計(jì)了三個(gè)學(xué)習(xí)方法:1.讓學(xué)生學(xué)會(huì)在探究中學(xué)。通過“對(duì)黑人嚴(yán)酷處境的探究”和對(duì)文中重點(diǎn)語句的探究,培養(yǎng)學(xué)生在探究中學(xué)習(xí)的能力。2.讓學(xué)生學(xué)會(huì)在讀中學(xué)。通過“誦讀法”指導(dǎo)學(xué)生在誦讀過程中感受演講詞內(nèi)在的魅力,學(xué)會(huì)在讀中學(xué)。3.讓學(xué)生學(xué)會(huì)在練習(xí)中學(xué)。通過“課外延伸練習(xí)法”,對(duì)所學(xué)的知識(shí)進(jìn)行運(yùn)用,培養(yǎng)學(xué)生的創(chuàng)新和自學(xué)能力。
