本研究旨在設計賽德克族文化融入國小四年級數學課程，並將此學習課程轉化成電子書。研究者從電子書開發過程中，蒐集6位參與成員進行會議討論的語料、參與成員個人撰寫的反思紀錄、研究者觀察反思札記及對參與成員的晤談語料等相關資料，以行動研究的方式探究此電子書製作過程的行動、反思與再行動歷程。研究結果發現，繪本電子書製作過程分為研究發生期、課程設計期、電子書轉化期、成果評估期等四個時期；故事情境以賽德克族祖先發源的《白石傳說》與族群間爭奪獵場的歷史典故為脈絡，以「概數」、「角度」與「三角形、四邊形性質」等數學概念為內涵。教師均肯定本研究所開發的繪本電子書，認為此媒材能提升學生的數學學習興趣。最後，透過研究結果與相關文獻對話，進而提出電子書教學與後續研究之建議。

This paper aimed at integrating Seediq culture and mathematical course design of fourth-grade in elementary school, and transforming this mathematical course into electronic book. During the process of electronic book development, researchers collected the meeting conversation video of six participants, took part in review minutes written by the six participants after meeting, collected researchers’ observation and review journals, and conversations with participants. Then, researchers utilized content analysis to explore the try, review and retry steps of electronic book making process. The results reveal that there are 4 periods of electronic book making process, paper occurrence, course design, electronic book transform, and result evaluation. At last, with the paper result, this article presents the corroboration of related works, and then proposes suggestions of electronic book teaching and follow-up studies.
