      摘要:抽象的數學概念和知識對于幼兒來說是十分枯燥、乏味的。為了便于幼兒感知理解,幼兒園里往往會利用一定的情景、人物等融入到數學的教學活動中,激發幼兒的興趣,但繁多的教學材料準備也對教師造成了一定的壓力。對此,教師可對多媒體在數學活動中運用的優勢進行探究,并提出多媒體課件在數學活動中的實際應用策略。

    幼兒教育

      一、多媒體在數學活動中運用的優勢

      (一)增加活動趣味性,讓數學活動不再枯燥《綱要》指出:教育活動內容的組織應充分考慮幼兒的學習方式和特點,注重綜合性、趣味性,寓教育于生活、游戲之中。相對于其他教學手段來說,多媒體課件的運用融入了各種卡通的圖片、音樂、動畫等,都是幼兒喜愛的元素,豐富多樣的表現形式,總能吸引幼兒的目光。對于幼兒來說,數學活動變得好玩了,學起來便不再覺得枯燥乏味。

      (二)大屏展示畫面,便于幼兒觀察、發現PPT、電子白板、flash等都是幼兒園中常用的多媒體教學手段,區別于傳統教學,多媒體課件往往需要大屏展示,其中電子白板課件更是可以直接在屏幕上加以操作,幼兒可以直接在屏幕上操作展示,既擺脫了一味的教師示范,讓幼兒參與到示范過程中,同時也避免了其他幼兒的消極等待,讓幼兒能夠更好地集中注意力進行觀察。

      (三)材料準備課件化,減少教師準備在幼兒園五大領域課程中,數學活動往往是需要準備材料最多的,除了幼兒的操作材料以外,還需要教師自己制作一些用于導入、情景、示范等步驟的材料。多媒體課件的運用不僅讓活動更富趣味性,同時原本教師所需的材料亦可以在課件中利用圖片、動畫進行展示、示范,配合課件中的音效,不僅減少了教室的各種手工材料,還能更好的調動幼兒的視聽感官。

      二、多媒體課件在數學活動中的實際應用

      (一)多媒體動畫滲透,讓幼兒融入情景受限于3-6歲幼兒的能力發展,我們在多媒體課件的制作中,往往會用一些音樂、語言、故事情景等集中幼兒的注意力,導入到將要學習的新知識當中。例如,在大班數學活動《對稱公主歷險記》中,直接以Flash制作的故事動畫進行導入,讓幼兒在動畫、音效的雙重作用下,了解故事情節,自愿成為協助對稱公主闖關的“勇士”,讓原本“認識對稱”的數學活動因為這個動畫導入而變成了一次關于對稱的闖關游戲。

      (二)多種功能齊用,讓知識與幼兒互動

      1.拖放功能,進行示范操作。

      拖放功能是電子白板中最為常見的。在進行數學活動時,可以請幼兒將畫面上的圖案、數字等物件利用白板筆隨意拖放、匹配,便于其他幼兒觀察驗證。例如,在大班數學活動《春天去派對》中,小蝴蝶遇到了河流,利用小喇叭吹出了一艘小船。活動中需要幼兒利用各種圖形根據小船的影子進行匹配、拼搭,但是幼兒的操作板相對來說比較小,在集體驗證的過程中,不適宜全體幼兒進行觀察、驗證。而電子白板的拖放功能則可以讓個別幼兒根據自己的拼搭結果,利用白板筆拖動各種圖形至小船的影子里,便于其他幼兒觀察驗證,同時也更好地集中了幼兒的注意力。

      2.容器功能,自動判斷對錯。

      容器功能是根據教師前期制作的對于答案正確與否的劃分,讓幼兒在活動中操作,由課件自主判斷,讓幼兒自己跟知識點進行互動,判斷對錯。例如,在中班數學《智多星大挑戰》中,其中有一關是“找找好朋友”。有5張數量1-5的5種不同的小動物,需要幼兒根據動物的數量匹配對應的數字。

      幼兒在操作時,將自己選擇的數字拖到與動物匹配的框里,如果正確,則會自動的發出掌聲;如果錯誤,拖進去的數字則會自動彈出回到原來的位置。在實際上課的過程中發現,幼兒都非常期待能得到掌聲的一刻,而當數字被彈出,幼兒往往立刻開始反思并尋找正確答案。整個環節中,教師的作用僅僅是宣布游戲規則以及最后的活動小結,幼兒在課件操作中就已經鞏固了數量與數字匹配的關系。

      3.透視功能,趣味驗證結果

      隱形墨水同樣是白板中比較常見的功能,而在數學活動中,隱形墨水的運用也會讓數學活動別有趣味。在大班數學活動《好奇的鱷魚王》中,當幼兒初步了解如何繪制統計圖后,利用鱷魚王巡視牛奶房的情景,引導幼兒根據不同奶牛產的牛奶的數量繪制統計圖。而在驗證幼兒操作結果的環節,原本空白的統計圖利用隱形墨水進行擦除,逐漸展現出正確的操作結果,引導幼兒進行驗證。雖然只是簡單的擦除動作,但是幼兒在“擦出”正確統計的過程中卻一個個的十分專注,這也讓幼兒對于自己的統計結果更具成功感。

      4.照相機功能,總結幼兒的答案

      拍照功能在白板課件中相對比較冷僻,它是白板課件自帶的一個截屏功能。在大班數學《讓誰先吃好呢》活動中,引導幼兒根據動物的不同特征為他們排隊,分別是“比嘴巴”“比尾巴”和“比耳朵”,幼兒利用操作材料自由進行操作,并集體驗證,在大屏幕上最終確認答案。這時候利用白板的照相機功能,將幼兒的排隊答案進行截屏放入統計表中。三次排隊過后,三個答案同時展現在一張統計表里,而每個答案都是幼兒自己集體驗證并拍照記錄下來的,對于幼兒來說,這是他們的答案,使自主性在游戲中得到了更好的發揮。

      幼師評職稱論文范文幼兒園的外在環境構建對幼兒成長教育的影響

      幼兒是我們每個人成長的重要時期,也是獨立人格的形成時期,這一時期的一些行為舉動可能會對人的性格產生極大的影響。幼兒園教育水平的高低直接影響兒童的健康成長,幼兒園的教育環境也是重要的教育資源,對我們每個人都產生了深刻的影響,想要培養學生全面發展的素質就必須擁有一個良好的教育環境,因此,環境教育在幼兒園教育中占據重要地位,下面文章通過教育環境的構建和幼兒教育的關系展開分析,強調環境對幼兒教育起到的作用,提升我國整體的幼兒教育水平。
