全球資訊網線上測驗系統之設計與製作

Abstract

目前全球資訊網(WWW)的資訊應用形式，已超越單純資訊檢 索( information retrieval)的階段，在各種應用中，線上 學習系統的發展 已非常普及，但線上學習系統仍未有完善的 線上測驗系統與之相配合。 針對這個缺失，本研究的目的乃 是在WWW環境中設計一模組化且功能完 整的線上測驗系統， 並針對系統中教師選題製成試卷的功能設計一個選 擇機制。 當題庫中試題之各屬性以及教師對其所欲安排的目標試卷之 描述方法都具備模糊特性時，傳統明確比對的選擇機制在這 樣一個具備 多項不明確屬性的環境中仍要有效的運作，將會 受到極大的挑戰。因此 ，提出一套能夠適用於上述具備模糊 屬性的項目集合和目標描述方式的 一般化選擇機制並評估其 效果，也是本研究的重要焦點。 Present WWW applications have already proceeded over the stage of simple information retrieval. Among all sorts of applications, on-line learning is evolved in all aspects. However, there is no sound on-line test- ing system compatible with on-line learning systems. Aiming at such a drawback, our research is focused on designing a modularized and complete on-line testing system in the WWW and a question-selection mechanism for teachers to create testing samples in the system. When all attributes of sample questions in the data- base and teachers' description of their desired test- ing sample selection, based on character of fuzzi- ness, traditional sample selection, based on crisp selection mechanisms, might face its shortcomings. Therefore proposing a general selection mechanism, capable of applying to fuzzy samples and goal descrip- tion and evaluating the mechanism are the foci of our research.
