「子由數學 e 學堂」為針對國小數學所設計的師生互動式學習平臺，老師可透過此平臺的自動出題系統來協助學生學習數學。原有 e 學堂是以滑鼠操作方式為設計的主要考量，但以觸控式平版已漸漸成為數位教室的主要學習工具。為因應此趨勢，本論文將以手指觸控為主的方式來重新設計此學習平臺，筆者除了重新設計 e 學堂的幾個主要功能外，也特別使用Bootstrap 軟體工具使得對不同尺寸的觸控平臺仍會有一致的輸出畫面與統一的操作步驟。;「ziyou emathschool」is an interactive mathematics learning platform designed specifically for the elementary school children in Taiwan. Inside the platform, teachers can utilize mathematic problems generated by automatic problem generator to help students to learn mathematics. The original webpage of emathschool are designed with assuming that users use mouse to interact with the platform. However, it is gradually out-of-date due to the sudden rise of touching-screen mobile device. The thesis will discuss how to redesign the emathschool so that it would be possible to use fingers to operate between webpages. Besides the redesign some major functions of emathschool, we also use the Bootstrap in our platform so that users will still have the same user interface on their screen even using different screen size of mobile device.
