寫作，是集結個人的邏輯思考、創意想像、組織表達的綜合體。本研究旨在探討WebQuest英文寫作課程的實施，對國中九年級學生在英文寫作的學習成效與態度之影響。以WebQuest融入英文寫作課程，藉由教學活動來蒐集與整合寫作素材，透過分組合作幫助學生完成寫作任務。 本行動研究以研究者所任教之國中九年級學生共34位為研究對象，以環保為主題在Moodle平台上建置WebQuest英文寫作教學網頁，進行為期十二週的課程。本研究透過分析教師的觀察記錄、學生半結構性訪談內容、問卷填答及文件蒐集等質性資料，並輔以英文短文前後測、英文寫作態度量表等量化資料進行資料之交互分析與討論，以深入了解學生在英文寫作教學活動的其他表現。研究結果發現： WebQuest英文寫作課程能提升學生整體的英文寫作成效。此外，WebQuest英文寫作課程有助於提升學生的英文寫作態度，尤其增強學生在「寫作策略」及「興趣與動機」兩個面向的表現。研究者也發現在學習歷程中，大部分學生能透過主動探索和合作學習方式來完成任務，訓練自我表達能力並培養自主學習的能力。而透過本行動研究歷程能促進教師的教學思維，提升專業知能。 最後，研究者針對研究限制進行說明，並依據研究結果提出建議，做為未來教學與研究實施之參考。 The purpose of the action research is to design and develop a WebQuest curriculum to improve ninth-grade students’ English writing. 34 ninth graders were recruited from a junior high school. Students worked in pairs and used Moodle to complete 3 WebQuest activities within 12 weeks.
