近年來，資訊科技的發展帶來了生活的便利，也促使教學教材和教學媒體多樣化。教師使用數學電子教科書進行教學輔助，其內容包含靜態文件、聲音、影像和互動式遊戲等。電子教科書的使用，使教學上能更吸引小學生的注意力且為教師帶來教學上的便利性。然而過去並無數學電子教科書品質衡量參考指標提供廠商與使用者參考。因此本研究目的在探究數學電子教科書品質要素，採用Kano二維品質模式做二維品質屬性分類，分析數學電子教科書品質改善項目。研究結果顯示數學電子教科書23個品質要素可歸類為17項線性品質、5項魅力品質、1項當然品質，並提出品質改善指標以增加使用者滿意及減少其不滿，擬可供國小教師或數學電子教科書編輯者做為參考，提升數學教科書評選方面的專業知能。

In recent years, the development of information technology has engendered convenience to life, and this has thus diversified teaching materials and media. Many teachers use mathematics electronic textbooks for teaching. Mathematics electronic textbooks include the following content: static texts, audios, videos, and interactive games. Such content can effectively attract the attention of elementary school children and can lead to teaching convenience for teachers. However, quality reference guidelines for mathematics electronic textbooks are not available for manufacturers and users. Therefore, this study explored the quality attributes of mathematics electronic textbooks by using the Kano two-dimensional quality model. According to the results, 17 quality attributes were classified as ＂one-dimensional quality,＂ 5 attributes were classified as ＂attractive quality,＂ and 1 attribute was ＂must-be quality.＂ The results of this study can serve as a reference for mathematics electronic textbook and electronic textbook researchers and for enhancing the professional knowledge of mathematics textbook selection.
