本篇論文是在敘述如何建置針對台灣國小學童使用數學題庫的網站平台, 並提供使用者註冊帳號及記錄使用題庫的成績, 附加使用者互動的站內簡訊, 討論版等各項功能。網站的建置方法是使用PHP網頁程式並搭配xajax函式庫產生javascript完成整個網站的網頁製作, 以及使用MySQL資料庫來儲存網站使用者資料。國小數學題庫的優點在於家長及老師可對學生出題, 學生作答完畢可記錄作答的成績, 提供家長及老師監督與輔導的依據, 題庫中的線上測驗亦不同於傳統紙本測驗, 更能提升學生的學習興趣, 藉此期望能達到提升國小學童的數學計算能力與加強基礎數學觀念的目的。 In the paper, we design a mathematical test bank website for elementary school. In the design, the users are divided into three categories as students, parents and teachers. Each student can select one or more teachers or parents as their mathematical advisors. The teacher/parents can generate the mathematical problems provided by the website in the form of either carbon copy or online interacting webpage. All the mathematical activities of students are recorded in the website. The teacher/parents can closely watch the mathematical status of the students. The mathematical test bank is the core of our website. The test bank are a set of many C++ programs. We design the programs in such a way that all the digits in the mathematical problems are generated randomly. If the problems are generated repeatly, the users won't find the same set of digits or diagrams in the problems.
