　　本研究目的有二，其一是發展數學科數位教科書設計原則，據以評估數位教科書單元教材設計；其二為研發及產出國民中學數學科數位教科書之單元教材。數位教科書之研發人員，將包含數位科技業者、教科書業者、數學教育專家與國中數學教師等，主要研究方法包括內容分析法、訪談法與可用性測試。透過內容分析，整理國內外相關理論與研究，發展數學科數位教科書設計原則；透過訪談法，蒐集國中數學科教師意見，共同參與數學單元數位教科書之研發；透過可用性測試，蒐集國中數學教師與學生之使用意見，據以修改數位教科書之設計。期望本研究對未來數學教學、數位教科書研發與研究等，具重要參考價值。

　　This study has two purposes: one is the development of digital textbook design principles in mathematics; the other is to develop a unit of digital textbook in mathematics. The developers of mathematics digital textbook include the persons of digital technology industry, of the textbook industry, the mathematics education experts, and the junior high school math teachers. The main research methods include content analysis, interviews and usability testing. Through content analysis, we can organize the relevant theories and researches to develop the principles of mathematics digital textbook design. Through interviews, we can collect the opinions of junior high school mathematics teachers, and design the mathematics digital textbook with them. Through usability testing, we can gather the views of teachers and students, and modify the design of digital textbook according to their opinions. We hope that this study can provide some suggestions upon the mathematics education and the development and research of digital textbooks, and help teaching and learning mathematics in junior high schools.
