函數(shù)在高中數(shù)學(xué)中占有很重要的比重,因而作為函數(shù)的第一節(jié)內(nèi)容,主要從三個(gè)實(shí)例出發(fā),引出函數(shù)的概念.從而就函數(shù)概念的分析判斷函數(shù),求定義域和函數(shù)值,再結(jié)合三要素判斷函數(shù)相等.課程目標(biāo)1.理解函數(shù)的定義、函數(shù)的定義域、值域及對(duì)應(yīng)法則。2.掌握判定函數(shù)和函數(shù)相等的方法。3.學(xué)會(huì)求函數(shù)的定義域與函數(shù)值。數(shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象:通過教材中四個(gè)實(shí)例總結(jié)函數(shù)定義;2.邏輯推理:相等函數(shù)的判斷;3.數(shù)學(xué)運(yùn)算:求函數(shù)定義域和求函數(shù)值;4.數(shù)據(jù)分析:運(yùn)用分離常數(shù)法和換元法求值域;5.數(shù)學(xué)建模:通過從實(shí)際問題中抽象概括出函數(shù)概念的活動(dòng),培養(yǎng)學(xué)生從“特殊到一般”的分析問題的能力,提高學(xué)生的抽象概括能力。重點(diǎn):函數(shù)的概念,函數(shù)的三要素。難點(diǎn):函數(shù)概念及符號(hào)y=f(x)的理解。

本節(jié)課是新版教材人教A版普通高中課程標(biāo)準(zhǔn)實(shí)驗(yàn)教科書數(shù)學(xué)必修1第四章第4.3.2節(jié)《對(duì)數(shù)的運(yùn)算》。其核心是弄清楚對(duì)數(shù)的定義,掌握對(duì)數(shù)的運(yùn)算性質(zhì),理解它的關(guān)鍵就是通過實(shí)例使學(xué)生認(rèn)識(shí)對(duì)數(shù)式與指數(shù)式的關(guān)系,分析得出對(duì)數(shù)的概念及對(duì)數(shù)式與指數(shù)式的 互化,通過實(shí)例推導(dǎo)對(duì)數(shù)的運(yùn)算性質(zhì)。由于它還與后續(xù)很多內(nèi)容,比如對(duì)數(shù)函數(shù)及其性質(zhì),這也是高考必考內(nèi)容之一,所以在本學(xué)科有著很重要的地位。解決重點(diǎn)的關(guān)鍵是抓住對(duì)數(shù)的概念、并讓學(xué)生掌握對(duì)數(shù)式與指數(shù)式的互化;通過實(shí)例推導(dǎo)對(duì)數(shù)的運(yùn)算性質(zhì),讓學(xué)生準(zhǔn)確地運(yùn)用對(duì)數(shù)運(yùn)算性質(zhì)進(jìn)行運(yùn)算,學(xué)會(huì)運(yùn)用換底公式。培養(yǎng)學(xué)生數(shù)學(xué)運(yùn)算、數(shù)學(xué)抽象、邏輯推理和數(shù)學(xué)建模的核心素養(yǎng)。1、理解對(duì)數(shù)的概念,能進(jìn)行指數(shù)式與對(duì)數(shù)式的互化;2、了解常用對(duì)數(shù)與自然對(duì)數(shù)的意義,理解對(duì)數(shù)恒等式并能運(yùn)用于有關(guān)對(duì)數(shù)計(jì)算。

對(duì)數(shù)與指數(shù)是相通的,本節(jié)在已經(jīng)學(xué)習(xí)指數(shù)的基礎(chǔ)上通過實(shí)例總結(jié)歸納對(duì)數(shù)的概念,通過對(duì)數(shù)的性質(zhì)和恒等式解決一些與對(duì)數(shù)有關(guān)的問題.課程目標(biāo)1、理解對(duì)數(shù)的概念以及對(duì)數(shù)的基本性質(zhì);2、掌握對(duì)數(shù)式與指數(shù)式的相互轉(zhuǎn)化;數(shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象:對(duì)數(shù)的概念;2.邏輯推理:推導(dǎo)對(duì)數(shù)性質(zhì);3.數(shù)學(xué)運(yùn)算:用對(duì)數(shù)的基本性質(zhì)與對(duì)數(shù)恒等式求值;4.數(shù)學(xué)建模:通過與指數(shù)式的比較,引出對(duì)數(shù)定義與性質(zhì).重點(diǎn):對(duì)數(shù)式與指數(shù)式的互化以及對(duì)數(shù)性質(zhì);難點(diǎn):推導(dǎo)對(duì)數(shù)性質(zhì).教學(xué)方法:以學(xué)生為主體,采用誘思探究式教學(xué),精講多練。教學(xué)工具:多媒體。一、 情景導(dǎo)入已知中國(guó)的人口數(shù)y和年頭x滿足關(guān)系 中,若知年頭數(shù)則能算出相應(yīng)的人口總數(shù)。反之,如果問“哪一年的人口數(shù)可達(dá)到18億,20億,30億......”,該如何解決?要求:讓學(xué)生自由發(fā)言,教師不做判斷。而是引導(dǎo)學(xué)生進(jìn)一步觀察.研探.

例7 用描述法表示拋物線y=x2+1上的點(diǎn)構(gòu)成的集合.【答案】見解析 【解析】 拋物線y=x2+1上的點(diǎn)構(gòu)成的集合可表示為:{(x,y)|y=x2+1}.變式1.[變條件,變?cè)O(shè)問]本題中點(diǎn)的集合若改為“{x|y=x2+1}”,則集合中的元素是什么?【答案】見解析 【解析】集合{x|y=x2+1}的代表元素是x,且x∈R,所以{x|y=x2+1}中的元素是全體實(shí)數(shù).變式2.[變條件,變?cè)O(shè)問]本題中點(diǎn)的集合若改為“{y|y=x2+1}”,則集合中的元素是什么?【答案】見解析 【解析】集合{ y| y=x2+1}的代表元素是y,滿足條件y=x2+1的y的取值范圍是y≥1,所以{ y| y=x2+1}={ y| y≥1},所以集合中的元素是大于等于1的全體實(shí)數(shù).解題技巧(認(rèn)識(shí)集合含義的2個(gè)步驟)一看代表元素,是數(shù)集還是點(diǎn)集,二看元素滿足什么條件即有什么公共特性。

內(nèi)容:分式方程的解法及應(yīng)用——初三中考數(shù)學(xué)第一輪復(fù)習(xí)學(xué)習(xí)目標(biāo):1、熟練利用去分母化分式方程為整式方程2、熟練利用分式方程的解法解決含參數(shù)的分式方程的問題重點(diǎn):分式方程的解法(尤其要理解“驗(yàn)”的重要性)難點(diǎn):含參數(shù)的分式方程問題預(yù)習(xí)內(nèi)容:1、觀看《分式方程的解法》《含參數(shù)分式方程增根問題》《解含參分式方程》視頻2、完成預(yù)習(xí)檢測(cè)

問題二:上述問題中,甲、乙的平均數(shù)、中位數(shù)、眾數(shù)相同,但二者的射擊成績(jī)存在差異,那么,如何度量這種差異呢?我們可以利用極差進(jìn)行度量。根據(jù)上述數(shù)據(jù)計(jì)算得:甲的極差=10-4=6 乙的極差=9-5=4極差在一定程度上刻畫了數(shù)據(jù)的離散程度。由極差發(fā)現(xiàn)甲的成績(jī)波動(dòng)范圍比乙的大。但由于極差只使用了數(shù)據(jù)中最大、最小兩個(gè)值的信息,所含的信息量很少。也就是說,極差度量出的差異誤差較大。問題三:你還能想出其他刻畫數(shù)據(jù)離散程度的辦法嗎?我們知道,如果射擊的成績(jī)很穩(wěn)定,那么大多數(shù)的射擊成績(jī)離平均成績(jī)不會(huì)太遠(yuǎn);相反,如果射擊的成績(jī)波動(dòng)幅度很大,那么大多數(shù)的射擊成績(jī)離平均成績(jī)會(huì)比較遠(yuǎn)。因此,我們可以通過這兩組射擊成績(jī)與它們的平均成績(jī)的“平均距離”來度量成績(jī)的波動(dòng)幅度。

(2)平均數(shù)受數(shù)據(jù)中的極端值(2個(gè)95)影響較大,使平均數(shù)在估計(jì)總體時(shí)可靠性降低,10天的用水量有8天都在平均值以下。故用中位數(shù)來估計(jì)每天的用水量更合適。1、樣本的數(shù)字特征:眾數(shù)、中位數(shù)和平均數(shù);2、用樣本頻率分布直方圖估計(jì)樣本的眾數(shù)、中位數(shù)、平均數(shù)。(1)眾數(shù)規(guī)定為頻率分布直方圖中最高矩形下端的中點(diǎn);(2)中位數(shù)兩邊的直方圖的面積相等;(3)頻率分布直方圖中每個(gè)小矩形的面積與小矩形底邊中點(diǎn)的橫坐標(biāo)之積相加,就是樣本數(shù)據(jù)的估值平均數(shù)。學(xué)生回顧本節(jié)課知識(shí)點(diǎn),教師補(bǔ)充。 讓學(xué)生掌握本節(jié)課知識(shí)點(diǎn),并能夠靈活運(yùn)用。

可以通過下面的步驟計(jì)算一組n個(gè)數(shù)據(jù)的第p百分位數(shù):第一步:按從小到大排列原始數(shù)據(jù);第二步:計(jì)算i=n×p%;第三步:若i不是整數(shù),而大于i的比鄰整數(shù)位j,則第p百分位數(shù)為第j項(xiàng)數(shù)據(jù);若i是整數(shù),則第p百分位數(shù)為第i項(xiàng)與第i+1項(xiàng)的平均數(shù)。我們?cè)诔踔袑W(xué)過的中位數(shù),相當(dāng)于是第50百分位數(shù)。在實(shí)際應(yīng)用中,除了中位數(shù)外,常用的分位數(shù)還有第25百分位數(shù),第75百分位數(shù)。這三個(gè)分位數(shù)把一組由小到大排列后的數(shù)據(jù)分成四等份,因此稱為四分位數(shù)。其中第25百分位數(shù)也稱為第一四分位數(shù)或下四分位數(shù)等,第75百分位數(shù)也稱為第三四分位數(shù)或上四分位數(shù)等。另外,像第1百分位數(shù),第5百分位數(shù),第95百分位數(shù),和第99百分位數(shù)在統(tǒng)計(jì)中也經(jīng)常被使用。例2、根據(jù)下列樣本數(shù)據(jù),估計(jì)樹人中學(xué)高一年級(jí)女生第25,50,75百分位數(shù)。

四、說教學(xué)過程課前預(yù)習(xí)我在教學(xué)《不懂就要問》前布置學(xué)生做以下預(yù)備工作:讀一讀,想一想課文主要寫誰的一件什么事?再讀一讀,數(shù)一數(shù)這一篇課文有幾個(gè)自然段,想一想每個(gè)自然段講什么?我之所以要求學(xué)生在課前做到這兩點(diǎn),是因?yàn)闉榱伺囵B(yǎng)學(xué)生有預(yù)習(xí)的一般意義而且在教學(xué)中提高質(zhì)量、增強(qiáng)密度。在教學(xué)過程中,為了能達(dá)到教學(xué)目標(biāo),突出重點(diǎn),突破難點(diǎn),我從以下幾點(diǎn)進(jìn)行設(shè)計(jì)?!镆郧榧に?。運(yùn)用情感教學(xué),不但能加深學(xué)生對(duì)課文的理解,而且能有效地激發(fā)學(xué)生學(xué)習(xí)的興趣的求知欲,調(diào)動(dòng)學(xué)生學(xué)習(xí)的積極性和主動(dòng)性,以提高課堂教學(xué)效果。因此,在教學(xué)中處處注意激發(fā)學(xué)生的興趣,調(diào)動(dòng)積極主動(dòng)性。

一、說教材《贈(zèng)劉景文》這首古詩(shī)的作者是蘇軾。這首古詩(shī)是寫秋末的景色,第一句以荷敗、菊殘,寫出了秋末的特征。接下來詩(shī)人以橙子的金黃與橘子的青綠,把深秋的景色點(diǎn)綴得色彩鮮明而富有生氣。詩(shī)人在此一反悲秋的調(diào)子,突出了秋天是收獲的季節(jié)。第二行詩(shī)贊頌了菊花的殘枝有傲霜凌寒的氣概。二、說教學(xué)目標(biāo)1.學(xué)會(huì)本課生字,重點(diǎn)理解詩(shī)句中“擎、殘、猶”的意思。了解詩(shī)句的含義。2.能正確、流利、有感情地朗讀古詩(shī)和背誦古詩(shī)。3.通過對(duì)詩(shī)句的誦讀感悟,培養(yǎng)學(xué)生豐富的想象力和語(yǔ)言表達(dá)能力。體會(huì)詩(shī)中描繪的濃濃秋色,感受詩(shī)歌美的意境和深刻的哲理。4.通過學(xué)習(xí)課文,喚起學(xué)生面對(duì)生活要樂觀向上,不泄氣,珍惜現(xiàn)在的大好時(shí)光。三、教學(xué)重、難點(diǎn)1.通過“欣賞意境”的訓(xùn)練和利用畫面再現(xiàn),從詞義理解到理解全句、全篇,來幫助學(xué)生領(lǐng)悟、感受全文。(重點(diǎn))2.通過對(duì)詩(shī)句的誦讀感悟,培養(yǎng)學(xué)生豐富的想象力和語(yǔ)言表達(dá)能力。體會(huì)詩(shī)中描繪的濃濃秋色,感受詩(shī)歌美的意境和深刻的哲理。(難點(diǎn))

一、說教材(一)教材分析這部分教材是在新課標(biāo)理念下新增加的一節(jié)實(shí)踐活動(dòng)課,重要是向?qū)W生滲透數(shù)字編碼的數(shù)學(xué)思想。本節(jié)課是通過日常生活中的一些事例,如:學(xué)號(hào)、門牌號(hào)、身份證號(hào)等使學(xué)生進(jìn)一步體會(huì)數(shù)字編碼在日常生活中的應(yīng)用,并通過實(shí)踐活動(dòng)進(jìn)行簡(jiǎn)單的數(shù)字編碼,培養(yǎng)學(xué)生的抽象、概括能力。(二)學(xué)生分析學(xué)生在第一學(xué)段已經(jīng)對(duì)數(shù)字編碼有了簡(jiǎn)單的了解,如:運(yùn)動(dòng)員的號(hào)牌、車牌號(hào)、郵編、門牌號(hào)等。學(xué)生也簡(jiǎn)單的知道數(shù)不僅可以用來表示數(shù)量和順序,還可以用來編碼。這節(jié)課就是在學(xué)生的生活經(jīng)驗(yàn)和已有知識(shí)的基礎(chǔ)上,進(jìn)一步體會(huì)數(shù)字編碼在日常生活中的應(yīng)用,并通過實(shí)踐活動(dòng)進(jìn)行簡(jiǎn)單的數(shù)字編碼,培養(yǎng)學(xué)生的抽象、概括能力。(三)教學(xué)目標(biāo)根據(jù)教材的特點(diǎn)和課標(biāo)要求,從學(xué)生的實(shí)際出發(fā),我確定了一下教學(xué)目標(biāo): 1、經(jīng)歷嘗試編寫本學(xué)校獨(dú)一無二學(xué)號(hào)的過程,使學(xué)生體會(huì)數(shù)字編碼在生活中的應(yīng)用,探索數(shù)字編碼的簡(jiǎn)單方法。 2.初步培養(yǎng)學(xué)生抽象概括的能力,提高應(yīng)用意識(shí)和實(shí)踐活動(dòng)能力。 3.體會(huì)數(shù)字應(yīng)用的廣泛性,提高學(xué)習(xí)數(shù)學(xué)的興趣和積極性。

一、說教材這篇童話通過擬人的手法,敘述的是一只小狗學(xué)叫的故事。構(gòu)思新穎,想象豐富,作者的情思寄寓在形象的描寫中,耐人尋味。 故事看起來,仿佛有點(diǎn)荒誕無稽,但細(xì)讀起來誰也不會(huì)去懷疑和談?wù)摴适碌恼鎸?shí)性,而是深刻地思考品評(píng)故事所暗示的“小狗終于做成真正的狗,找回迷失的自我”的主題。作者曾經(jīng)說過:“在每一件事物中都有一個(gè)故事,這些故事在桌子的木頭中,在玻璃中,在玫瑰中……” 《小狗學(xué)叫》正是以現(xiàn)實(shí)生活為基礎(chǔ),在每一件事中挖掘故事,把現(xiàn)實(shí)世界的偶然現(xiàn)象和必然因素統(tǒng)一起來,把故事情節(jié)的曲折變化和人物性格的邏輯發(fā)展結(jié)合起來,通過這一高超的藝術(shù)辯證法,幽默地展示出現(xiàn)實(shí)社會(huì)中的某些現(xiàn)象,使人們?cè)谛β曋惺艿浇逃蛦l(fā)。我們可用多媒體課件等形象的教學(xué)手段,拉近學(xué)生與文本之間的距離。
