教學(xué)目標(biāo):知識(shí)與能力目標(biāo):1.能夠借助三角函數(shù)的定義及單位圓推導(dǎo)出三角函數(shù)的誘導(dǎo)公式 2.能夠運(yùn)用誘導(dǎo)公式,把任意角的三角函數(shù)的化簡(jiǎn)、求值問題轉(zhuǎn)化為銳角的三角函數(shù)的化簡(jiǎn)、求值問題情感目標(biāo):1.通過誘導(dǎo)公式的探求,培養(yǎng)學(xué)生的探索能力、鉆研精神和科學(xué)態(tài)度 2.通過誘導(dǎo)公式探求工程中的合作學(xué)習(xí),培養(yǎng)學(xué)生團(tuán)結(jié)協(xié)作的精神; 3. 通過誘導(dǎo)公式的運(yùn)用,培養(yǎng)學(xué)生的劃歸能力,提高學(xué)生分析問題和解決問題的能力。 一導(dǎo)入:二、自學(xué)(閱讀教材第110---112頁(yè),回答下列問題) 在直角坐標(biāo)系下,角的終邊與圓心在原點(diǎn)的單位圓相交于,則,(一)終邊相同的角:終邊相同的角的 公式一:_______ ________________(二)關(guān)于軸的對(duì)稱點(diǎn)的特征: 。對(duì)于角而言:角關(guān)于軸對(duì)稱的角為_______公式二:__________ _________ _________
5.發(fā)揮想象。兩段文字都運(yùn)用了想象的手法。“閉了眼,樹上仿佛已經(jīng)滿是桃兒、杏兒、梨兒”“看著看著,這件花衣好像被風(fēng)兒吹動(dòng),叫你希望看見一點(diǎn)更美的山的肌膚”“那點(diǎn)兒薄雪好像忽然害了羞”,這些想象,既突出了景物的特點(diǎn),又融入了作者的情感,可謂是一舉兩得。6.講究描寫的順序。兩段文字都采用空間順序展開描寫,景物的層次清晰。要注意觀察的順序,是由近及遠(yuǎn),還是由遠(yuǎn)及近?是由上到下,還是由下到上?這是指空間的變換。還可以以時(shí)間的變化或游覽的先后為順序。這樣,所描寫的景物才不會(huì)雜亂無(wú)章。7.寫景還要融入情感。“一切景語(yǔ)皆情語(yǔ)”。寫景貴有情,在描繪客觀景物的同時(shí),要把自己的喜怒哀樂等思想感情融注到作品中去,使讀者產(chǎn)生共鳴,進(jìn)而給讀者帶來愉悅之情、陶醉之情,將讀者帶入特定的情景之中,受到美的熏陶,獲得美的享受。如《從百草園到三味書屋》中“夏天百草園”一段“油蛉在這里低唱,蟋蟀們?cè)谶@里彈琴”,在作者小時(shí)候聽來,油蛉、蟋蟀的叫聲猶如人在悠揚(yáng)的琴聲伴奏下婉轉(zhuǎn)地低唱,其間傳遞著作者愉快、喜悅的心聲,表達(dá)作者對(duì)大自然的喜愛和向往之情。目標(biāo)導(dǎo)學(xué)三:實(shí)戰(zhàn)演練描寫你家鄉(xiāng)一處有特色的景物,包括自然景物和社會(huì)景物,要求描寫細(xì)致、生動(dòng),表達(dá)你對(duì)家鄉(xiāng)的熱愛之情。例文展示:
a.第127頁(yè)隨堂練習(xí)1第(1)題。b.一個(gè)多邊形的邊都相等,這是一個(gè)正多邊形嗎?c.一個(gè)多邊形的內(nèi)角都相等,這是一個(gè)正多邊形嗎?d.所以,一個(gè)相等,也都相等的多邊形才是。(此檢測(cè)主要是讓學(xué)說出多邊形和正多邊形的定義,因?yàn)槭窃谌切巍⑺倪呅蔚幕A(chǔ)上,定義是一致的,所以不深究。在教材的處理上,把正多邊形放在了前面,兩個(gè)較為簡(jiǎn)單的概念放在一起,便于學(xué)生理解和掌握。)2.各組展示四邊形的內(nèi)角和的計(jì)算方法。3.各組展示五邊形的內(nèi)角和的計(jì)算方法。(由各組派代表上臺(tái)板演,其它組補(bǔ)充,真正讓學(xué)生動(dòng)起來)4.各組選擇前面最優(yōu)的方法,口述六邊形、七邊形的內(nèi)角和的算法。(以此上,學(xué)生可以利用對(duì)比的方法,選擇作出過三角形的一個(gè)頂點(diǎn)的對(duì)角線的方法,讓學(xué)生探索發(fā)現(xiàn)規(guī)律。)5.據(jù)此,你們認(rèn)為n邊形的內(nèi)角和應(yīng)該怎樣計(jì)算。(注意n的條件)五、當(dāng)堂訓(xùn)練。

2、內(nèi)容結(jié)構(gòu)本單元由導(dǎo)語(yǔ)、第七課“中華一家親”、第八課“中國(guó)人中國(guó)夢(mèng)”組成。每 課各設(shè)兩框。單元導(dǎo)語(yǔ)首先對(duì)“和諧”的內(nèi)涵作了分析。其次,導(dǎo)語(yǔ)闡明中華民 族是一個(gè)大家庭,我們要像愛護(hù)自己的眼睛一樣愛護(hù)民族團(tuán)結(jié),要加快民族地區(qū) 經(jīng)濟(jì)社會(huì)文化發(fā)展,促進(jìn)民族團(tuán)結(jié)。我們要堅(jiān)持“和平統(tǒng)一、一國(guó)兩制”基本方 針,實(shí)現(xiàn)祖國(guó)統(tǒng)一。再次,導(dǎo)語(yǔ)揭示了中國(guó)夢(mèng)的意義和價(jià)值,提出實(shí)現(xiàn)中國(guó)夢(mèng)的 客觀要求。最后,導(dǎo)語(yǔ)將中國(guó)夢(mèng)的實(shí)現(xiàn)與當(dāng)今時(shí)代相關(guān)聯(lián),闡明了實(shí)現(xiàn)中國(guó)夢(mèng)與 做自信中國(guó)人的內(nèi)在聯(lián)系,提出青少年要與祖國(guó)和時(shí)代共成長(zhǎng)的現(xiàn)實(shí)命題。第一框“促進(jìn)民族團(tuán)結(jié)”。第一 目介紹了我國(guó)多民族的基本國(guó)情和我國(guó)的民 族政策,重點(diǎn)落在“加強(qiáng)和鞏固民族團(tuán)結(jié),維護(hù)祖國(guó)統(tǒng)一,是中華民族的最高利 空。第二目通過事實(shí)描述、原因分析,闡述民族地區(qū)經(jīng)濟(jì)社會(huì)文化建設(shè)取得重大 成就、人民生活不斷改善的事實(shí),引導(dǎo)學(xué)生分析取得這些成就的原因,重點(diǎn)落在 “維護(hù)和促進(jìn)民族團(tuán)結(jié),是每個(gè)公民的辨圣職責(zé)和光榮義務(wù)”。本框從我國(guó)多民 族的國(guó)情以及民族地區(qū)經(jīng)濟(jì)、社會(huì)和文化發(fā)展的角度談民族團(tuán)結(jié)的重要意義,為 下一框講述“維護(hù)祖國(guó)統(tǒng)一”打下基礎(chǔ)。
