「子由數學小學堂」是一個依據臺灣國小數學課程綱要所設計的數學學習網站,使用者可以透過此網站在線上即時產生符合需求的數學練習卷。為了提昇功能,小學堂的核心出題引擎在民國 102 年全面改寫,本論文探討如何配合這些更動來重新設計後端的題型編輯系統與前端的使用者出題介面,使得小學堂得以更順利的運作。;"Ziyou Emathschool" is an elementary mathematics-learning website in which the mathematics problems can be generated online by various computer programs. All mathematics problems in the website are designed to follow the offical mathematical curriculum for Taiwan elementary school closely. On the year of 2013, to enhance its functionalities, the mathematics problem generator behind the website was redesigned from the start. With response to the changes of problem engine, the thesis discusses how to redesign the rear-end interface of mathematical problem editor system and front-end user interface used to generate the mathematics problems in order to get smoother operations for the new website engine.
