    《蜀道難》說(shuō)課稿(一) 2021-2022學(xué)年統(tǒng)編版高中語(yǔ)文選擇性必修下冊(cè)

    (3)夸張到極致的技巧: (學(xué)生尋找出詩(shī)歌中的夸張語(yǔ)句,談出感受)(4)多樣的詩(shī)歌意境: 為了表達(dá)主觀感受與目的的需要,詩(shī)歌中構(gòu)織不同的意境:高峻、宏偉、神奇、凄清、恐怖等各種意境均有描繪,而這些意境又統(tǒng)統(tǒng)表現(xiàn)一個(gè)“難”字。(5)神秘的傳說(shuō): “五丁開(kāi)山”“太陽(yáng)神回車(chē)”“子規(guī)哀啼”等傳說(shuō)的出現(xiàn),使全詩(shī)籠罩一種神秘氣氛,也從另一個(gè)角度表現(xiàn)出了一個(gè)“難”字。九.課后探討本文主旨?xì)v來(lái)爭(zhēng)議不定,明確詩(shī)歌的主旨和情感。 我首先指導(dǎo)方法, “知人論世” 是評(píng)論文學(xué)作品的一種原則 。知人,就是了解作者其人及作者與作品的關(guān)系。論世,就是要了解作者所處的時(shí)代、環(huán)境。接著打出李白在長(zhǎng)安的介紹。說(shuō)明李白躊躇滿(mǎn)志而來(lái),卻受到權(quán)貴的忌恨,被放還鄉(xiāng)。接著打出唐玄宗時(shí)期的介紹,說(shuō)明太平景象背后潛伏的危機(jī)。然后讓學(xué)生分組討論,本課的寫(xiě)作意圖是什么?

    《蜀相》說(shuō)課稿(一) 2021-2022學(xué)年統(tǒng)編版高中語(yǔ)文選擇性必修下冊(cè)

    我將本節(jié)課分為三個(gè)部分:1.情境導(dǎo)入先運(yùn)用多媒體,展示電影《赤壁》的幾張圖片,通過(guò)“赤壁之戰(zhàn)”將三國(guó)時(shí)期這場(chǎng)經(jīng)典戰(zhàn)爭(zhēng)諸葛亮的智謀呈現(xiàn)給學(xué)生,吸引學(xué)生走進(jìn)歷史,激發(fā)想象力和趣味性,提高學(xué)生的學(xué)習(xí)主動(dòng)性。在成功吸引學(xué)生注意力過(guò)后,再向他們說(shuō),這只是歷史中的一部分,在“赤壁之戰(zhàn)”前后,諸葛亮一生的故事是怎樣的呢?下面我們來(lái)看看唐代大詩(shī)人杜甫的《蜀相》,他是怎樣用精辟的詩(shī)句概括的。2.講授新課在成功吸引學(xué)生注意力后,迅速將他們帶入課文講授階段。第一,進(jìn)行作者介紹,其目的是為了使學(xué)生在整體上把握詩(shī)人的經(jīng)歷、寫(xiě)作技巧、藝術(shù)風(fēng)格及寫(xiě)作背景。第二,多誦讀,多推敲,理解詩(shī)中的言外之意。第三,把握重點(diǎn)詞語(yǔ),分析景物意象,體味作者的思想感情和作品的深層意蘊(yùn)。感受詩(shī)人憂(yōu)國(guó)憂(yōu)民強(qiáng)烈的愛(ài)國(guó)主義感情。

    8、板書(shū)裝在套子里的人別里科夫的形象——有形的套子套己——無(wú)形的套子套人第二課時(shí)合作探究:目標(biāo)挖掘主題及現(xiàn)實(shí)意義。問(wèn)題設(shè)置,銜接上節(jié)課內(nèi)容,層層深入。1、結(jié)合上節(jié)課別里科夫的形象分析:他的思想被什么套住,其悲劇原因在哪?(根據(jù)人物形象的分析與社會(huì)背景的了解,直擊主題。)沙皇腐朽的專(zhuān)制統(tǒng)治套住了他的思想,沙皇的清規(guī)戒律使他不敢越雷池一步,所以他是受害者,但他的身份性格以及特定的社會(huì)環(huán)境,又讓他成為沙皇統(tǒng)治的捍衛(wèi)者。2、他戀愛(ài)的情節(jié)以及科瓦連科這兩個(gè)人物的塑造的意義?(從人物以及主題入手,推翻沙皇的腐朽反動(dòng)的統(tǒng)治,必須是每一個(gè)人都敢于打破套子,喚醒革新,更新觀念,拒絕腐朽。)別里科夫渴望打破束縛,也想革新,而科瓦連科兩個(gè)人物體現(xiàn)朝氣活潑,以及勇于打破常規(guī)束縛的勇氣,為革新升起了一片曙光。3、塑造別里科夫的手法,除了一般刻畫(huà)人物方法外,還有什么方法?

    (六)說(shuō)教學(xué)策略1.專(zhuān)題性海量的媒介信息必須加以選擇或者整合,以項(xiàng)目為依據(jù),進(jìn)行信息篩選,形成專(zhuān)題性閱讀與交流;培養(yǎng)學(xué)生對(duì)文本信息“化零為整”的能力,提升跨媒介閱讀與交流學(xué)習(xí)的充實(shí)感。2.情境化情境教學(xué)應(yīng)指向?qū)W生的應(yīng)用,建構(gòu)富有符合時(shí)代氣息的內(nèi)容,與生活經(jīng)驗(yàn)更加貼合,對(duì)學(xué)生的語(yǔ)言建構(gòu)與運(yùn)用有所提升,在情境中能夠有效地進(jìn)行交流。3.任務(wù)化以任務(wù)為導(dǎo)向的序列化學(xué)習(xí),可以為學(xué)生構(gòu)建學(xué)習(xí)路線圖、學(xué)習(xí)框架等具體任務(wù)引導(dǎo);或以跨媒介的認(rèn)識(shí)與應(yīng)用為任務(wù)的設(shè)置引導(dǎo);甚至以閱讀和交流作為序列化安排的實(shí)踐引導(dǎo)。4.整合性跨媒介閱讀與交流是結(jié)合線上線下的資源,形成新的“超媒介”,也能實(shí)現(xiàn)對(duì)信息進(jìn)行“深加工”,多種媒介的信息整合只為一個(gè)核心教學(xué)內(nèi)容服務(wù)。5.互文性語(yǔ)言文字是語(yǔ)文之生命,我們是立足于語(yǔ)言文字的探討,音樂(lè)、圖像、視頻等文本與傳統(tǒng)語(yǔ)言文字文本形成互文,觸發(fā)學(xué)生對(duì)學(xué)習(xí)內(nèi)容立體化和具體化的感悟,提升學(xué)生的審美能力。

Because…。這也是本單元的教學(xué)重點(diǎn)。通過(guò)本單元的學(xué)習(xí),學(xué)生應(yīng)能較流利地運(yùn)用所學(xué)詞匯和句型描述動(dòng)物,表達(dá)個(gè)人喜好。(二)單元知識(shí)結(jié)構(gòu)1.詞匯動(dòng)物名稱(chēng) tiger, elephant, koala, dolphin, etc.詞匯描述性形容詞: smart, cute, ugly, clever, shy, etc.國(guó)家名: Australia, South Africa2.句型Why do you like koala hears? Because they are cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(三)單元整體目標(biāo)1.Master the vocabulary2.Master and use: Why do you like koalas? Because they am cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(四)單元教學(xué)重難點(diǎn)一覽(五)單元學(xué)情分析學(xué)生此前已經(jīng)學(xué)過(guò)由why, where, what 引導(dǎo)的特殊疑問(wèn)句句型,具有了學(xué)習(xí)本單元知識(shí)的認(rèn)知前提。形形色色的動(dòng)物能激發(fā)學(xué)生的好奇心,產(chǎn)生了解它們的欲望,這有利于本單元知識(shí)的教學(xué)和學(xué)生學(xué)習(xí)興趣的培養(yǎng)。

    (3)分解因式:1+x+x(x+1)+x(x+1)2+…+x(x+1)n(n為正整數(shù)).解析:(1)根據(jù)已知計(jì)算過(guò)程直接得出因式分解的方法即可;(2)根據(jù)已知分解因式的方法可以得出答案;(3)由(1)中計(jì)算發(fā)現(xiàn)規(guī)律進(jìn)而得出答案.解:(1)因式分解的方法是提公因式法,共應(yīng)用了3次;(2)分解因式1+x+x(x+1)+x(x+1)2+…+x(x+1)2015,需應(yīng)用上述方法2016次,結(jié)果是(1+x)2015;(3)1+x+x(x+1)+x(x+1)2+…+x(x+1)n=(1+x)n+1.方法總結(jié):解決此類(lèi)問(wèn)題需要認(rèn)真閱讀,理解題意,根據(jù)已知得出分解因式的規(guī)律是解題關(guān)鍵.三、板書(shū)設(shè)計(jì)1.提公因式分解因式的一般步驟:(1)觀察;(2)適當(dāng)變形;(3)確定公因式;(4)提取公因式.2.提公因式法因式分解的應(yīng)用本課時(shí)是在上一課時(shí)的基礎(chǔ)上進(jìn)行的拓展延伸,在教學(xué)時(shí)要給學(xué)生足夠主動(dòng)權(quán)和思考空間,突出學(xué)生在課堂上的主體地位,引導(dǎo)和鼓勵(lì)學(xué)生自主探究,在培養(yǎng)學(xué)生創(chuàng)新能力的同時(shí)提高學(xué)生的邏輯思維能力.

    北師大初中八年級(jí)數(shù)學(xué)下冊(cè)等腰三角形的判定與反證法教案

    方法總結(jié):本題結(jié)合三角形內(nèi)角和定理考查反證法,解此題關(guān)鍵要懂得反證法的意義及步驟.反證法的步驟是:(1)假設(shè)結(jié)論不成立;(2)從假設(shè)出發(fā)推出矛盾;(3)假設(shè)不成立,則結(jié)論成立.在假設(shè)結(jié)論不成立時(shí)要注意考慮結(jié)論的反面所有可能的情況.如果只有一種,那么否定一種就可以了,如果有多種情況,則必須一一否定.三、板書(shū)設(shè)計(jì)1.等腰三角形的判定定理:有兩個(gè)角相等的三角形是等腰三角形(等角對(duì)等邊).2.反證法(1)假設(shè)結(jié)論不成立;(2)從假設(shè)出發(fā)推出矛盾;(3)假設(shè)不成立,則結(jié)論成立.解決幾何證明題時(shí),應(yīng)結(jié)合圖形,聯(lián)想我們已學(xué)過(guò)的定義、公理、定理等知識(shí),尋找結(jié)論成立所需要的條件.要特別注意的是,不要遺漏題目中的已知條件.解題時(shí)學(xué)會(huì)分析,可以采用執(zhí)果索因(從結(jié)論出發(fā),探尋結(jié)論成立所需的條件)的方法.

    【類(lèi)型二】 根據(jù)不等式的變形確定字母的取值范圍如果不等式(a+1)x<a+1可變形為x>1,那么a必須滿(mǎn)足________.解析:根據(jù)不等式的基本性質(zhì)可判斷a+1為負(fù)數(shù),即a+1<0,可得a<-1.方法總結(jié):只有當(dāng)不等式的兩邊都乘(或除以)一個(gè)負(fù)數(shù)時(shí),不等號(hào)的方向才改變.三、板書(shū)設(shè)計(jì)1.不等式的基本性質(zhì)性質(zhì)1:不等式的兩邊都加上(或減去)同一個(gè)整式,不等號(hào)的方向不變;性質(zhì)2:不等式的兩邊都乘(或除以)同一個(gè)正數(shù),不等號(hào)的方向不變;性質(zhì)3:不等式的兩邊都乘(或除以)同一個(gè)負(fù)數(shù),不等號(hào)方向改變.2.把不等式化成“x>a”或“x<a”的形式“移項(xiàng)”依據(jù):不等式的基本性質(zhì)1;“將未知數(shù)系數(shù)化為1”的依據(jù):不等式的基本性質(zhì)2、3.本節(jié)課學(xué)習(xí)不等式的基本性質(zhì),在學(xué)習(xí)過(guò)程中,可與等式的基本性質(zhì)進(jìn)行類(lèi)比,在運(yùn)用性質(zhì)進(jìn)行變形時(shí),要注意不等號(hào)的方向是否發(fā)生改變;課堂教學(xué)時(shí),鼓勵(lì)學(xué)生大膽質(zhì)疑,通過(guò)練習(xí)中易出現(xiàn)的錯(cuò)誤,引導(dǎo)學(xué)生歸納總結(jié),提升學(xué)生的自主探究能力.

    方法總結(jié):解題的關(guān)鍵是由題意列出不等式求出這個(gè)少算的內(nèi)角的取值范圍.探究點(diǎn)二:多邊形的外角和定理【類(lèi)型一】 已知各相等外角的度數(shù),求多邊形的邊數(shù)正多邊形的一個(gè)外角等于36°,則該多邊形是正()A.八邊形 B.九邊形C.十邊形 D.十一邊形解析:正多邊形的邊數(shù)為360°÷36°=10,則這個(gè)多邊形是正十邊形.故選C.方法總結(jié):如果已知正多邊形的一個(gè)外角,求邊數(shù)可直接利用外角和除以這個(gè)角即可.【類(lèi)型二】 多邊形內(nèi)角和與外角和的綜合運(yùn)用一個(gè)多邊形的內(nèi)角和與外角和的和為540°,則它是()A.五邊形 B.四邊形C.三角形 D.不能確定解析:設(shè)這個(gè)多邊形的邊數(shù)為n,則依題意可得(n-2)×180°+360°=540°,解得n=3,∴這個(gè)多邊形是三角形.故選C.方法總結(jié):熟練掌握多邊形的內(nèi)角和定理及外角和定理,解題的關(guān)鍵是由已知等量關(guān)系列出方程從而解決問(wèn)題.

    北師大初中八年級(jí)數(shù)學(xué)下冊(cè)分式方程的應(yīng)用教案

    解:(1)設(shè)第一次購(gòu)買(mǎi)的單價(jià)為x元,則第二次的單價(jià)為1.1x元,根據(jù)題意得14521.1x-1200x=20,解得x=6.經(jīng)檢驗(yàn),x=6是原方程的解.(2)第一次購(gòu)買(mǎi)水果1200÷6=200(千克).第二次購(gòu)買(mǎi)水果200+20=220(千克).第一次賺錢(qián)為200×(8-6)=400(元),第二次賺錢(qián)為100×(9-6.6)+120×(9×0.5-6.6)=-12(元).所以?xún)纱喂操嶅X(qián)400-12=388(元).答:第一次水果的進(jìn)價(jià)為每千克6元;該老板兩次賣(mài)水果總體上是賺錢(qián)了,共賺了388元.方法總結(jié):本題具有一定的綜合性,應(yīng)該把問(wèn)題分解成購(gòu)買(mǎi)水果和賣(mài)水果兩部分分別考慮,掌握這次活動(dòng)的流程.三、板書(shū)設(shè)計(jì)列分式方程解應(yīng)用題的一般步驟是:第一步,審清題意;第二步,根據(jù)題意設(shè)未知數(shù);第三步,根據(jù)題目中的數(shù)量關(guān)系列出式子,并找準(zhǔn)等量關(guān)系,列出方程;第四步,解方程,并驗(yàn)根,還要看方程的解是否符合題意;最后作答.
