課 題.d樹葉貼畫

課題：樹葉的聯(lián)想

教學目標：

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)學生想象能力和動手創(chuàng)造能力。教學重點與難點:

根據(jù)樹葉的形狀和顏色，組合成適宜的樹葉粘貼畫�；顒訙蕚�:

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生創(chuàng)意學生作品欣賞一、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、請同學們看看老師展示的這些葉子像什么呢？”（觀察討論）教師小結：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、再讓學生看看這是什么？（出示孔雀）讓學生欣賞

教師小結：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，并對個別學生適當指導，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。“這幾幅畫呀，構圖較好，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)，引導啟發(fā)學生的聯(lián)想思維和創(chuàng)造能力。該課非常貼近學生的實際生活，親切質樸的鄉(xiāng)土內容、通過輕松活躍的課堂氣氛、合作探究的學習方式大大激發(fā)了學生們的學習興趣，能夠使學生體會到了“生活中不是缺少美，而是缺少發(fā)現(xiàn)”的美學理念，達到了很教學對象:三年級教學時間：一課時

《美術課程標準》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）進行美術教學。”農村小學的美術課，最令教師患難的就是學生的學具材料很齊全。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)學生興趣，為以后的樹葉畫打下基礎。教學目標：情感、態(tài)度與價值觀：感受自然材質樹葉獨特的美，產生利用廢舊物品、自然材料進行創(chuàng)作的興趣。

知識與技能：提升學生對造型藝術語言的廣義認識，訓練學生概括、夸張的表現(xiàn)能力，通過聯(lián)想、想象開啟學生的創(chuàng)新思維。

過程與方法:通過選葉、拼擺、粘貼訓練學生的動手能力，通過合作拼貼培養(yǎng)學生的合作意識，養(yǎng)成愛整潔、講衛(wèi)生的行為習慣。教學重點：

1.材料的選擇運用；2.樹葉貼畫的技巧。教學難點：

形象特征表現(xiàn)、創(chuàng)新。教學準備：

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（供6個小組學生使用）；樹葉畫作品若干，樹葉范畫2幅；獎品（樹葉書簽）若干。

學生:糨糊、卡紙教學過程：

（一）激趣導入、引出課題

教師提問：同學們喜歡畫畫嗎？請大家說說什么叫做畫（板書）？

教師對學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

教師給同學們帶來了禮物，請各位小組長打開桌上的紙盒，讓每位學生拿上一片樹葉，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：

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，就可以制作美術作品。（三）欣賞樹葉美術作品

教師展示本校學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，介紹本校美術課開展樹葉制作的情況。

小結：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個學生對《牛》進行“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、學生按照由易到難的順序完成樹葉動物樹葉人物樹葉風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：片片樹葉真有趣，

我來把它巧設計。選葉聯(lián)想再拼擺，粘貼成畫真美麗。

（五）學生作業(yè)

1、同學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：肯定學生的創(chuàng)造精神，從構圖、色彩搭配、材料使用等方面提出具體建議。

教師小結：今天同學們的美術學習又有了不少的收獲，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！
