課 題.d樹葉貼畫
課題:樹葉的聯(lián)想
教學(xué)目標(biāo):
1、認識常見的葉子,發(fā)現(xiàn)葉子的形狀、大小、顏色各有不同。2、能大膽想象利用不同的葉子拼貼樹葉畫。3、培養(yǎng)學(xué)生想象能力和動手創(chuàng)造能力。教學(xué)重點與難點:
根據(jù)樹葉的形狀和顏色,組合成適宜的樹葉粘貼畫;顒訙(zhǔn)備:
1、在平時散步時已認識多種不同形狀的樹葉2、收集大小不一、形狀和顏色各異的樹葉3、事先請同學(xué)們收集一些樹葉活動流程:介紹樹葉粘貼的方法
欣賞各種樹葉欣賞范畫介紹樹葉粘貼的方法學(xué)生創(chuàng)意學(xué)生作品欣賞一、欣賞各種樹葉
1、知道它們有大有小,形狀不一,可以組成有趣的圖案2、請同學(xué)們看看老師展示的這些葉子像什么呢?”(觀察討論)教師小結(jié):它們形狀都是不一樣的,有大的,有小的,有長的,短的。二、欣賞范畫
1、你們想看嗎?老師把樹葉放在一起變成了一幅什么畫?(金魚)觀察金魚的身體是用什么形狀組合的?(橢圓形葉子)那它的尾巴又是什么樣子的葉子變出來的呢?(有點像花的葉子變出來的)
2、再讓學(xué)生看看這是什么?(出示孔雀)讓學(xué)生欣賞
教師小結(jié):原來每一片樹葉和不同的樹葉組合就會變出不同的圖形。
三、介紹樹葉粘貼的方法
擺的時候要先想好它的位置,不要擠在一起,這樣才好看!物體拼好后,再一片片地在樹葉的背后均勻地抹上漿糊,貼在畫紙上,再用手輕輕壓一壓。四、創(chuàng)意
教師邊巡視,并對個別學(xué)生適當(dāng)指導(dǎo),重點幫助正確地挑選樹葉的形狀拼圖來布局畫面。五、作品欣賞
請完成的同學(xué)把圖畫貼在黑板上,互相看一看,說你最喜歡哪幅畫?為什么喜歡它?
教師可以挑出幾幅好的畫稍作講評!斑@幾幅畫呀,構(gòu)圖較好,畫面很滿,添加的裝飾不多,拼的很像。(最主要的是樹葉的形狀找的好)

樹葉貼畫(美術(shù)資源的開發(fā)課例)
《樹葉貼畫》是一堂典型的鄉(xiāng)土課程,就地取材,利用鄉(xiāng)村隨處可見的樹葉,根據(jù)其豐富多彩的顏色、形態(tài),引導(dǎo)啟發(fā)學(xué)生的聯(lián)想思維和創(chuàng)造能力。該課非常貼近學(xué)生的實際生活,親切質(zhì)樸的鄉(xiāng)土內(nèi)容、通過輕松活躍的課堂氣氛、合作探究的學(xué)習(xí)方式大大激發(fā)了學(xué)生們的學(xué)習(xí)興趣,能夠使學(xué)生體會到了“生活中不是缺少美,而是缺少發(fā)現(xiàn)”的美學(xué)理念,達到了很教學(xué)對象:三年級教學(xué)時間:一課時
《美術(shù)課程標(biāo)準(zhǔn)》指出“盡可能運用自然環(huán)境(如自然景觀、自然材料等)以及校園和社會生活中的資源(如活動、事件和環(huán)境等)進行美術(shù)教學(xué)!鞭r(nóng)村小學(xué)的美術(shù)課,最令教師患難的就是學(xué)生的學(xué)具材料很齊全。因此,我們只好因地制宜、就地取材來拓寬美術(shù)課程資源,選擇本地容易收集的各種樹葉作為材料,進行樹葉貼畫、樹葉拓印、樹葉添畫、樹葉剪紙、樹葉書簽的系列活動,讓學(xué)生建立“變廢為寶”的思想,體會運用自然材料創(chuàng)作的樂趣,培養(yǎng)學(xué)生的審美情趣與創(chuàng)造能力。本課為“樹葉畫”系列課程中的第一課,通過簡單的樹葉拼擺造型,激發(fā)學(xué)生興趣,為以后的樹葉畫打下基礎(chǔ)。教學(xué)目標(biāo):情感、態(tài)度與價值觀:感受自然材質(zhì)樹葉獨特的美,產(chǎn)生利用廢舊物品、自然材料進行創(chuàng)作的興趣。
知識與技能:提升學(xué)生對造型藝術(shù)語言的廣義認識,訓(xùn)練學(xué)生概括、夸張的表現(xiàn)能力,通過聯(lián)想、想象開啟學(xué)生的創(chuàng)新思維。
過程與方法:通過選葉、拼擺、粘貼訓(xùn)練學(xué)生的動手能力,通過合作拼貼培養(yǎng)學(xué)生的合作意識,養(yǎng)成愛整潔、講衛(wèi)生的行為習(xí)慣。教學(xué)重點:
1.材料的選擇運用;2.樹葉貼畫的技巧。教學(xué)難點:
形象特征表現(xiàn)、創(chuàng)新。教學(xué)準(zhǔn)備:
教師:選擇大小不同、形狀各異、顏色豐富的樹葉,壓平、涼干、裝與6個紙盒內(nèi)(供6個小組學(xué)生使用);樹葉畫作品若干,樹葉范畫2幅;獎品(樹葉書簽)若干。
學(xué)生:糨糊、卡紙教學(xué)過程:
(一)激趣導(dǎo)入、引出課題
教師提問:同學(xué)們喜歡畫畫嗎?請大家說說什么叫做畫(板書)?
教師對學(xué)生的回答給予一定的肯定(態(tài)度、情感方面),暫不判斷正誤。出示一幅樹葉粘貼畫作品:這是不是畫?這是什么做成的畫?板書課題:樹葉貼畫。(二)樹葉欣賞
教師給同學(xué)們帶來了禮物,請各位小組長打開桌上的紙盒,讓每位學(xué)生拿上一片樹葉,仔細觀察、欣賞、聯(lián)想、討論。
請各組派代表說說自己的樹葉的形狀、色彩與紋理。教師小結(jié):
樹葉是大自然的杰作,每一片樹葉都帶著大自然的靈氣,有自己獨特的形狀、大小、紋理,呈現(xiàn)出獨特的美,引發(fā)人們美的遐想。
樹葉有很多用途(如綠化、凈化空氣、燃料、肥料、藥用等)。用樹葉代替彩筆和顏料,就可以制作美術(shù)作品。(三)欣賞樹葉美術(shù)作品
教師展示本校學(xué)生用樹葉制作的樹葉貼畫、樹葉添畫、樹葉剪紙、樹葉書簽、樹葉拓印等,介紹本校美術(shù)課開展樹葉制作的情況。
小結(jié):利用樹葉,對樹葉進行加工,可以制成許多美麗的作品,其中樹葉貼畫是最基本、最簡單的方法。(四)探究制作方法
1、教師出示樹葉貼畫范作,旁邊貼上空白卡紙,示范制作過程。2、抽2個學(xué)生對《!愤M行“變形創(chuàng)作”,并簡述自己的粘貼方法。
3、教師介紹如何表現(xiàn)事物的形象特征,如何利用樹葉概括、夸張事物的特征。
板書制作過程:選葉聯(lián)想拼擺粘貼
4、學(xué)生按照由易到難的順序完成樹葉動物樹葉人物樹葉風(fēng)景樹葉添畫樹葉拓印樹葉剪紙樹葉書簽等拼貼畫制作。兒歌小結(jié):片片樹葉真有趣,
我來把它巧設(shè)計。選葉聯(lián)想再拼擺,粘貼成畫真美麗。
(五)學(xué)生作業(yè)
1、同學(xué)合作制作一幅樹葉貼畫。2、給作品命名,寫上作者姓名。3、主意整潔,保持良好環(huán)境。(六)評價、交流
1、生評:自評說說我的創(chuàng)意,說說我的方法,說說我的收獲。他評夸夸他的特色,找找他的問題。
2、師評:肯定學(xué)生的創(chuàng)造精神,從構(gòu)圖、色彩搭配、材料使用等方面提出具體建議。
教師小結(jié):今天同學(xué)們的美術(shù)學(xué)習(xí)又有了不少的收獲,我們用自己靈巧的雙手,把一片片尋常的樹葉變成了一幅幅精美的圖畫樹葉貼畫。同學(xué)們可以把這些畫貼到教室或家里,讓你時時都能感受到大自然的氣息。為了讓我們生活的世界更美麗,讓我們一起來努力吧!
