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,主要從三個實例出發(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:通過教材中四個實例總結(jié)函數(shù)定義;2.邏輯推理:相等函數(shù)的判斷;3.數(shù)學(xué)運算:求函數(shù)定義域和求函數(shù)值;4.數(shù)據(jù)分析:運用分離常數(shù)法和換元法求值域;5.數(shù)學(xué)建模:通過從實際問題中抽象概括出函數(shù)概念的活動,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:函數(shù)的概念,函數(shù)的三要素。難點:函數(shù)概念及符號y=f(x)的理解。

例7 用描述法表示拋物線y=x2+1上的點構(gòu)成的集合.【答案】見解析 【解析】 拋物線y=x2+1上的點構(gòu)成的集合可表示為:{(x,y)|y=x2+1}.變式1.[變條件,變設(shè)問]本題中點的集合若改為“{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}中的元素是全體實數(shù).變式2.[變條件,變設(shè)問]本題中點的集合若改為“{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的全體實數(shù).解題技巧(認(rèn)識集合含義的2個步驟)一看代表元素,是數(shù)集還是點集,二看元素滿足什么條件即有什么公共特性。

(4)寫第三間小屋時作者為什么說“在我們的小屋里,住著所有我們認(rèn)識的人,唯獨沒有我們自己”?明確:這是一個信息高度發(fā)達的社會,我們能從不同渠道接受各種紛繁復(fù)雜的信息,漸漸,有的人就被這個信息社會所同化了,常常隨波逐流,用他人的觀點來肯定事物的價值,常常以為眾人所追求的就是他們自己想要的。于是別人的思想、外在的信息代替了他們自己的思想,使自己成為缺乏思想和思考的人,所以說“唯獨沒有我們自己”。(5)你認(rèn)為在第三間精神小屋中應(yīng)該怎樣“安放我們自身”呢?明確:安放自身需要思考,擁有獨立的思想。(6)請你結(jié)合日常生活,說說你是否嘗試過如此構(gòu)建“精神的三間小屋”。【教學(xué)提示】引導(dǎo)學(xué)生在對“精神的三間小屋”的理解基礎(chǔ)上來審視生活,從而達到反思生活,審視自我精神世界,建構(gòu)自我精神世界的目的。

一、說教材《我不能失信》是統(tǒng)編小學(xué)語文三年級下冊第六單元的一篇略讀課文,講述的是一個星期天,宋慶齡全家準(zhǔn)備到父親的一個朋友家去,可是宋慶齡想起要在當(dāng)天教朋友小珍疊花籃,雖然父親和母親都勸她改天再教,可是宋慶齡還是留下來,履行了自己的諾言,贊美了宋慶齡誠實守信的可貴品質(zhì)。選編這篇課文的意圖,一是讓學(xué)生感受宋慶齡誠實守信的可貴品質(zhì),在思想上受到熏陶和感染,在做人做事上面獲得啟示;二是讓學(xué)生初步體會通過人物語言、動作、表情來表現(xiàn)人物的寫作手法,為本單元的習(xí)作奠定基礎(chǔ);三是培養(yǎng)學(xué)生獨立閱讀的能力。二、說教學(xué)目標(biāo)1.認(rèn)識5個生字,正確、流利地朗讀課文,有感情地朗讀人物對話。 2.把握文章的主要內(nèi)容,感受宋慶齡誠實守信的可貴品質(zhì),使自己在做人做事方面獲得啟示。 3.培養(yǎng)獨立閱讀能力,通過人物對話來領(lǐng)會人物的內(nèi)心世界和性格特點。三、說教學(xué)重難點1.理解宋慶齡拒絕父母的建議,堅持留在家里的原因。(重點)2.引導(dǎo)學(xué)生透過人物對話和動作來領(lǐng)會人物的內(nèi)心世界和性格特點。(難點)

一、說教材《夜書所見》是統(tǒng)編教材三年級語文上冊第二組課文中的古詩。這是南宋詩人葉紹翁寫的客游在外,因秋風(fēng)落葉,感到孤獨郁悶,由看到遠處籬笆下的燈火,料想是小孩在捉蟋蟀,不禁回憶起自己的故鄉(xiāng)和童年的生活,于是那種郁悶之情又被一種親切之感所代替。二、說教學(xué)目標(biāo) 1.會認(rèn)會寫本課生字。2.引導(dǎo)學(xué)生理解詩意體會詩人所描繪的情景。3.學(xué)習(xí)借助注釋理解詩意,體會詩歌的感情。4.有感情的朗讀古詩,背誦古詩。 激發(fā)和培養(yǎng)學(xué)習(xí)古詩的興趣。三、說教學(xué)重難點1.學(xué)習(xí)借助注釋理解詩意,體會詩歌的感情。(重點)2.感受詩中的秋意和詩情,激發(fā)學(xué)習(xí)古詩的興趣。(難點)

一、說教材《贈劉景文》這首古詩的作者是蘇軾。這首古詩是寫秋末的景色,第一句以荷敗、菊殘,寫出了秋末的特征。接下來詩人以橙子的金黃與橘子的青綠,把深秋的景色點綴得色彩鮮明而富有生氣。詩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)會本課生字,重點理解詩句中“擎、殘、猶”的意思。了解詩句的含義。2.能正確、流利、有感情地朗讀古詩和背誦古詩。3.通過對詩句的誦讀感悟,培養(yǎng)學(xué)生豐富的想象力和語言表達能力。體會詩中描繪的濃濃秋色,感受詩歌美的意境和深刻的哲理。4.通過學(xué)習(xí)課文,喚起學(xué)生面對生活要樂觀向上,不泄氣,珍惜現(xiàn)在的大好時光。三、教學(xué)重、難點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)2.通過對詩句的誦讀感悟,培養(yǎng)學(xué)生豐富的想象力和語言表達能力。體會詩中描繪的濃濃秋色,感受詩歌美的意境和深刻的哲理。(難點)

三、說教學(xué)重難點1.能帶著問題默讀課文,說說這個“粗瓷大碗”的故事。。(重點)2.抓住重點語句,借助關(guān)鍵字詞,感悟趙一曼的品質(zhì)。(難點)四、說教法學(xué)法創(chuàng)設(shè)情境在教學(xué)本課中必不可少,多媒體在此時的作用顯而易見。而在閱讀過程中,老師只需引領(lǐng)學(xué)生深入、有效地開展有層次的閱讀,盡量留出空間,讓學(xué)生自主學(xué)習(xí),并注意鼓勵創(chuàng)新性的理解和表達。 略課文不像精讀課文那么嚴(yán)格細(xì)致,只要求粗知文章大意,因此,在課上可以教給學(xué)生掃讀和跳讀的方法。但這并不意味著就可以馬馬虎虎,草草了事。粗知是相對精讀課文而言的,略讀課文少了識字、學(xué)詞學(xué)句等許多頭緒,教學(xué)目標(biāo)更為集中。但在閱讀的方法上,也不排斥精讀,文章的重點、精彩之處還是要引導(dǎo)學(xué)生品讀,感受到人物的心情、品質(zhì)。

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)實踐活動課,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、門牌號、身份證號等使學(xué)生進一步體會數(shù)字編碼在日常生活中的應(yīng)用,并通過實踐活動進行簡單的數(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)對數(shù)字編碼有了簡單的了解,如:運動員的號牌、車牌號、郵編、門牌號等。學(xué)生也簡單的知道數(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)驗和已有知識的基礎(chǔ)上,進一步體會數(shù)字編碼在日常生活中的應(yīng)用,并通過實踐活動進行簡單的數(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)教材的特點和課標(biāo)要求,從學(xué)生的實際出發(fā),我確定了一下教學(xué)目標(biāo): 1、經(jīng)歷嘗試編寫本學(xué)校獨一無二學(xué)號的過程,使學(xué)生體會數(shù)字編碼在生活中的應(yīng)用,探索數(shù)字編碼的簡單方法。 2.初步培養(yǎng)學(xué)生抽象概括的能力,提高應(yīng)用意識和實踐活動能力。 3.體會數(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,仿佛有點荒誕無稽,但細(xì)讀起來誰也不會去懷疑和談?wù)摴适碌恼鎸嵭裕巧羁痰厮伎计吩u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)實生活為基礎(chǔ),在每一件事中挖掘故事,把現(xiàn)實世界的偶然現(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)實社會中的某些現(xiàn)象,使人們在笑聲中受到教育和啟發(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。

本板塊的活動主題是“談?wù)摴?jié)日活動”(Talk about festival activities),主要是從貼近學(xué)生日常生活的角度來切入“節(jié)日”主題。學(xué)生會聽到發(fā)生在三個國家不同節(jié)日場景下的簡短對話,對話中的人們正在參與或?qū)⒁H歷不同的慶?;顒?。隨著全球化的進程加速,國際交流日益頻繁,無論是國人走出國門還是外國友人訪問中國,都已成為司空見慣的事情。因此,該板塊所選取的三個典型節(jié)日場景都是屬于跨文化交際語境,不僅每組對話中的人物來自不同的文化背景,對話者的身份和關(guān)系也不盡相同。1.
