一、導入要新穎.
俗話說：“良好的開端是成功的一半”。上課也一樣。教師的循循誘導，能讓學生產生強烈的求知慾和好奇心，從而更積極主動地參加課堂教學，爲整節課的成功作準備。可以採用以下幾種導入：⒈歌曲導入。⒉設置懸念。當然導入很多，教學中不能單一的用一種導入，也許這種導入剛開始學生覺得很有勁，但天天用學生就會厭倦了。所以教師設計時要多多新穎，多多改變，儘量多樣性。
二、創設情景，多用直觀教學.
由於國小生年齡較小，生活經驗不豐富，知識範圍有限，決定了他們對直觀、新穎、有趣的材料容易理解和接受。比如學生學習“good morning ﹑good afternoon ﹑good evening”這三個問候詞時很容易混淆，我就用道具設置情景：畫了三幅圖，有從東面初升的太陽表示上午，有正在上方 的太陽表示中午，有明亮的月亮表示晚上。再叫學生用“good morning ﹑good afternoon ﹑good evening”來說，加深了學生的印象。作爲一個國小英語教師表情要豐富，如果表情呆滯，語言平淡，學生就不能全身心投入學習中。所以在課堂上，老師需要生動地表演，豐富的.表情，使學生進入一個童話世界。在製作教具時可讓學生自己動手畫、動手做。在教學中要用到的圖片，可以提早幾天佈置下去，當他們的作品被運用在課堂上時，孩子們都很興奮。這樣使學生體會到成功的喜悅也激發了學英語的興趣。此外畫圖片，也培養了學生的繪畫能力，也可讓他們熟悉一下將要學的新知識，真是一舉多得啊!
三、運用多種教學方式使學生“玩學結合”.
愛玩是孩子的天性。教師在課前充分利用
