本節(jié)課是三角函數(shù)的繼續(xù),三角函數(shù)包含正弦函數(shù)、余弦函數(shù)、正切函數(shù).而本課內(nèi)容是正切函數(shù)的性質(zhì)與圖像.首先根據(jù)單位圓中正切函數(shù)的定義探究其圖像,然后通過圖像研究正切函數(shù)的性質(zhì). 課程目標(biāo)1、掌握利用單位圓中正切函數(shù)定義得到圖象的方法;2、能夠利用正切函數(shù)圖象準(zhǔn)確歸納其性質(zhì)并能簡(jiǎn)單地應(yīng)用.數(shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象:借助單位圓理解正切函數(shù)的圖像; 2.邏輯推理: 求正切函數(shù)的單調(diào)區(qū)間;3.數(shù)學(xué)運(yùn)算:利用性質(zhì)求周期、比較大小及判斷奇偶性.4.直觀想象:正切函數(shù)的圖像; 5.數(shù)學(xué)建模:讓學(xué)生借助數(shù)形結(jié)合的思想,通過圖像探究正切函數(shù)的性質(zhì). 重點(diǎn):能夠利用正切函數(shù)圖象準(zhǔn)確歸納其性質(zhì)并能簡(jiǎn)單地應(yīng)用; 難點(diǎn):掌握利用單位圓中正切函數(shù)定義得到其圖象.
1.圓柱、圓錐、圓臺(tái)的表面積與多面體的表面積一樣,圓柱、圓錐、圓臺(tái)的表面積也是圍成它的各個(gè)面的面積和。利用圓柱、圓錐、圓臺(tái)的展開圖如圖,可以得到它們的表面積公式:2.思考1:圓柱、圓錐、圓臺(tái)的表面積之間有什么關(guān)系?你能用圓柱、圓錐、圓臺(tái)的結(jié)構(gòu)特征來解釋這種關(guān)系嗎?3.練習(xí)一圓柱的一個(gè)底面積是S,側(cè)面展開圖是一個(gè)正方體,那么這個(gè)圓柱的側(cè)面積是( )A 4πS B 2πS C πS D 4.練習(xí)二:如圖所示,在邊長(zhǎng)為4的正三角形ABC中,E,F(xiàn)分別是AB,AC的中點(diǎn),D為BC的中點(diǎn),H,G分別是BD,CD的中點(diǎn),若將正三角形ABC繞AD旋轉(zhuǎn)180°,求陰影部分形成的幾何體的表面積.5. 圓柱、圓錐、圓臺(tái)的體積對(duì)于柱體、錐體、臺(tái)體的體積公式的認(rèn)識(shí)(1)等底、等高的兩個(gè)柱體的體積相同.(2)等底、等高的圓錐和圓柱的體積之間的關(guān)系可以通過實(shí)驗(yàn)得出,等底、等高的圓柱的體積是圓錐的體積的3倍.
② 命題的含義:判斷一件事情的句子,叫做命題,如果一個(gè)句子沒有對(duì)某一件事情作出任何判斷,那么它就不是命題.活動(dòng)目的:通過課后的總結(jié),使學(xué)生對(duì)定義、命題等概念有更清楚的認(rèn)識(shí),讓學(xué)生在頭腦中對(duì)本節(jié)課進(jìn)行系統(tǒng)的歸納與整理.教學(xué)效果:學(xué)生在有了前面對(duì)定義、特別是命題概念的學(xué)習(xí)后,能了解命題的結(jié)構(gòu),以及哪些是命題,使學(xué)生對(duì)命題的學(xué)習(xí)有了清楚的認(rèn)識(shí)。第五環(huán)節(jié) 課后練習(xí)學(xué)習(xí)小組搜集八年級(jí)數(shù)學(xué)課本中的新學(xué)的部分定義、命題,看誰(shuí)找得多.四、教學(xué)反思本節(jié)課的設(shè)計(jì)具有如下特點(diǎn):(1)采用了“小品表演”的形式引入新課,意在激起學(xué)生對(duì)數(shù)學(xué)的興趣,讓學(xué)生知道,數(shù)學(xué)不是枯燥無味的。并能從表演中不同的人對(duì)“黑客”這個(gè)名詞的不同理解更好地悟出“定義”的含義。
各位老師、同學(xué)們:大家上午好!今天我說課的題目是《世說新語(yǔ)》二則之《期行》。我將從教材分析、說教法學(xué)法、說教學(xué)過程、說板書設(shè)計(jì)等幾個(gè)方面來進(jìn)行我的說課。一、教材分析(一)說教材的地位和作用《世說新語(yǔ)》二則是語(yǔ)文出版社七年級(jí)上冊(cè)的文言課文。《陳太丘與友期》是《世說新語(yǔ)》“方正”門中的,主要是寫陳太丘之子元方聰穎機(jī)智,懂禮識(shí)儀。文中 “無信”“無禮”二詞為全篇核心,可見作者的寫作目的是借“陳元方責(zé)客”來說明“信”和“禮”的重要性。告訴學(xué)生一個(gè)道理——人必須明禮誠(chéng)信。(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)合學(xué)生的認(rèn)知結(jié)構(gòu)及其心理特征,我制定了以下的教學(xué)目標(biāo):A:積累文言詞語(yǔ),疏通文意B:培養(yǎng)語(yǔ)感,培養(yǎng)閱讀淺易文言文的能力。
明確:示例:①我讀出了富春江的山是高峻、連綿、充滿生機(jī)的,從“夾岸高山,皆生寒樹,負(fù)勢(shì)競(jìng)上,互相軒邈,爭(zhēng)高直指,千百成峰”一句可以體現(xiàn)。②我讀出了富春江的水是清澈、湍急的,從“水皆縹碧,千丈見底。游魚細(xì)石,直視無礙。急湍甚箭,猛浪若奔”一句可以體現(xiàn)。要點(diǎn):水的特征:清澈、湍急。山的特征:高峻、連綿、充滿生機(jī)。目標(biāo)導(dǎo)學(xué)四:修辭品析,寫作借鑒1.本文綜合運(yùn)用了夸張、比喻、擬人、對(duì)偶等修辭手法,請(qǐng)舉例并賞析其作用。明確:夸張:“千丈見底”“直視無礙”用夸張手法描寫水的澄澈透明;比喻:“急湍甚箭,猛浪若奔”連用兩個(gè)比喻,生動(dòng)形象地描寫水的湍急;擬人:“負(fù)勢(shì)競(jìng)上,互相軒邈”把山擬人化,形象地寫出了山的高峻和綿延不斷;對(duì)偶:“泉水激石,泠泠作響;好鳥相鳴,嚶嚶成韻”運(yùn)用對(duì)偶,句式整齊,極具音韻美。
第一環(huán)節(jié):回顧引入活動(dòng)內(nèi)容:①什么叫做定義?舉例說明.②什么叫命題?舉例說明. 活動(dòng)目的:回顧上節(jié)知識(shí),為本節(jié)課的展開打好基礎(chǔ).教學(xué)效果:學(xué)生舉手發(fā)言,提問個(gè)別學(xué)生.第二環(huán)節(jié):探索命題的結(jié)構(gòu)活動(dòng)內(nèi)容:① 探討命題的結(jié)構(gòu)特征觀察下列命題,發(fā)現(xiàn)它們的結(jié)構(gòu)有什么共同特征?(1)如果兩個(gè)三角形的三條邊對(duì)應(yīng)相等,那么這兩個(gè)三角形全等.(2)如果一個(gè)三角形是等腰三角形,那么這個(gè)三角形的兩個(gè)底角相等.(3)如果一個(gè)四邊形的一組對(duì)邊平行且相等,那么這個(gè)四邊形是平行四邊形.(4)如果一個(gè)四邊的對(duì)角線相等,那么這個(gè)四邊形是矩形.(5)如果一個(gè)四邊形的兩條對(duì)角線互相垂直,那么這個(gè)四邊形是菱形.② 總結(jié)命題的結(jié)構(gòu)特征(1)上述命題都是“如果……,那么……”的形式.(2)“如果……”是已知的事項(xiàng),“那么……”是由已知事項(xiàng)推斷出的結(jié)論.
一、情境導(dǎo)入神舟十號(hào)是中國(guó)神舟號(hào)系列飛船之一,主要由推進(jìn)艙(服務(wù)艙)、返回艙、軌道艙組成.神舟十號(hào)在酒泉衛(wèi)星發(fā)射中心“921工位”,于2013年6月11日17時(shí)38分02.666秒發(fā)射,由長(zhǎng)征二號(hào)F改進(jìn)型運(yùn)載火箭(遙十)“神箭”成功發(fā)射.在軌飛行十五天左右,加上發(fā)射與返回,其中停留天宮一號(hào)十二天,共搭載三位航天員——聶海勝、張曉光、王亞平.6月13日與天宮一號(hào)進(jìn)行對(duì)接.6月26日回歸地球.要讀懂這段報(bào)導(dǎo),你認(rèn)為要知道哪些名稱和術(shù)語(yǔ)的含義?二、合作探究探究點(diǎn)一:定義 下列語(yǔ)句屬于定義的是()A.明天是晴天B.長(zhǎng)方形的四個(gè)角都是直角C.等角的補(bǔ)角相等D.平行四邊形是兩組對(duì)邊分別平行的四邊形解析:作出正確選擇的關(guān)鍵是理解定義的含義.A是對(duì)天氣的預(yù)測(cè),B是描述長(zhǎng)方形的性質(zhì),C是描述補(bǔ)角的性質(zhì).只有D符合定義的概念.故選D.方法總結(jié):定義指的是對(duì)術(shù)語(yǔ)和名稱的含義的描述,是對(duì)一個(gè)事物區(qū)分于其他事物的本質(zhì)特征的描述,而不是對(duì)其性質(zhì)的判斷.
求證:直角三角形的兩個(gè)銳角互余.解析:分析這個(gè)命題的條件和結(jié)論,根據(jù)已知條件和結(jié)論畫出圖形,寫出已知、求證,并寫出證明過程.已知:如圖所示,在△ABC中,∠C=90°.求證:∠A與∠B互余.證明:∵∠A+∠B+∠C=180°(三角形內(nèi)角和等于180°),又∠C=90°,∴∠A+∠B=180°-∠C=90°.∴∠A與∠B互余.方法總結(jié):解此類題首先根據(jù)題意將文字語(yǔ)言變成符號(hào)語(yǔ)言,畫出圖形,最后再經(jīng)過分析論證,并寫出證明的過程.三、板書設(shè)計(jì)命題分類公理:公認(rèn)的真命題定理:經(jīng)過證明的真命題證明:推理的過程經(jīng)歷實(shí)際情境,初步體會(huì)公理化思想和方法,了解本教材所采用的公理,讓學(xué)生對(duì)真假命題有一個(gè)清楚的認(rèn)識(shí),從而進(jìn)一步了解定理、公理的概念.培養(yǎng)學(xué)生的語(yǔ)言表達(dá)能力.
吳均是一位善寫山水的大家,他自小好學(xué)而又才智出眾,但“家世寒賤”,性格耿直。在門閥制度相當(dāng)嚴(yán)格的南朝梁,出身于庶族寒門的人,想要在政治上得到重用,著實(shí)不易,再加上他性格直來直去,口無遮攔,更是會(huì)四處碰壁。所幸的是,起先著名文史學(xué)家沈約看中了吳均的文章,“頗相稱賞”。接著,吳均得到了刺史柳惲的賞識(shí),提拔他當(dāng)了郡主簿,常在一起賦詩(shī)答對(duì)。他的詩(shī)文“清拔有古氣”,自成一家,時(shí)人紛紛效仿,稱為“吳均體”。書信內(nèi)容為何是山水游記魏晉六朝是中國(guó)歷史上政治最混亂、社會(huì)最痛苦的時(shí)代,然而卻是精神上極自由、極富智慧和藝術(shù)精神的時(shí)代。大自然成了情趣高雅之士審美活動(dòng)的重要背景和舞臺(tái),移情山水成了當(dāng)時(shí)的社會(huì)風(fēng)尚。在書信中描畫山水,寄托情志,成為好友間交流的一種流行方式,文人們通過書信內(nèi)斂地表露自己的人生取向,他們的文學(xué)經(jīng)歷給后世留下了寶貴的文化遺產(chǎn)。吳均的《與朱元思書》《與施從事書》和《與顧章書》,以及陶弘景的《答謝中書書》皆是如此。
The price is the same as(the price was)before the war.價(jià)格與戰(zhàn)前相同。(4)定語(yǔ)從句中的“關(guān)系代詞+助動(dòng)詞be”可以省略。The ticket(that/which was)booked by his sister has been sent to him.他妹妹訂的那張票已送到了他那里。Step 5 PracticeActivity 3(1) Guide students to complete the four activities in the Using Structures part of exercise book, in which activities 1 and 2 focus on ellipsis in dialogue answers, activity 3 focus on signs and headlines, two typical situations where ellipsis is used, and activity 4 focus on ellipsis in diary, an informal style.(2) Combine the examples in the above activities, ask students to summarize the omitted situations in groups, and make their own summary into a poster, and post it on the class wall after class to share with the class.(This step should give full play to the subjectivity of students, and teachers should encourage students to conclude different ellipsis phenomena according to their own understanding, they can conclude according to the different parts omitted in the sentence.)Step 6 Homework1. Understand and master the usages of ellipsis;2. Finish the other exercises in Using structures of Workbook.1、通過本節(jié)內(nèi)容學(xué)習(xí),學(xué)生是否理解和掌握省略的用法;2、通過本節(jié)內(nèi)容學(xué)習(xí),學(xué)生能否根據(jù)上下文語(yǔ)境或情景恢復(fù)句子中省略的成分,體會(huì)使用省略的效果;3、通過本節(jié)內(nèi)容學(xué)習(xí),學(xué)生能否獨(dú)立完成練習(xí)冊(cè)和導(dǎo)學(xué)案中的相關(guān)練習(xí)。
