本研究之目的在探討於國小英語教學中實施合作學習對於學生的英語學習會產生哪些影響。本研究採用合作行動研究。研究期間將近一學期，以國小五年級的一個班級共35位學生為觀察對象。在研究過程中以質性方法進行資料的蒐集，包括：參與觀察紀錄、問卷、訪談、檔案文件以及研究者省思札記。資料分析顯示合作學習對學生有幾項正面之影響： 一、學生在合作學習情境下使用英語的機會增加，對於英語學習也更有興趣。 二、實施合作學習之後，學生的學習態度顯得較為主動、積極。在課堂上發言或發問的情形增加；而且不僅能體認自己的學習責任，也會關心同儕學習情況。 三、合作學習能增進同儕彼此良性互動之機會；本研究之合作學習採取異質分組之方式，使學生有機會與平常較少互動的同儕相處，有助於學生人際關係的拓展。
