本研究主要探討大學部學生的批判性思考及創造力，及與主修科系，性別，文化背景和學習態度的關聯性。本研究方法是質量合併，利用質性分析學生在討論區的意見，在使用敘述統計探討研究結果。 本研究共有一百四十六位大學生參與，其中包含五十七位國際企業學系主修學生，四十六位財務金融學系主修學生及四十三位大眾傳播學系主修學生。本研究者在討論區開設三個不同的討論主題，其討論主題分別與日常生活，學生目前生活及未來生活相關。在研究期間，本研究者與英語教學領域人員們依照學生上課情形與討論區的意見，分析並分類參與學生的上課態度及討論區意見的批判性思考與創造力的等級。 本研究結果顯示大學部學生的主修科系，性別，文化背景和學習態度會影響學生展現不同程度的的批判性思考及創造力。換言之，不同主修科系，不同性別，不同文化背景及不同上課態度的學生會導致學生有不同程度及面向的批判性思考及創造力。本研究的研究結果與先前的研究結果一致。 有鑑於本研究的研究結果與討論，若有意於在課堂中使用小組或大班性討論的老師，必須先考慮學生的科系，性別，文化背景或上課態度。若能依照學生的不同的特性來設計教材與內容，老師就可以更有效設計適合的討論主題並有效的培養學生的批判性思考與創意。 This study is aimed to investigate college student’s critical thinking and creativity and the relation between academic background, gender, cultural background, learning attitude and information process in terms of critical thinking and creativity.
