最後進行了一個實驗，以問卷方式獲得使用者回饋的寶貴意見，並以統計數據驗證了使用者對系統的滿意程度，也為未來的線上測驗系統，提供一些改進或是發展的方向。 Assessment plays an important role in the distance-learning research. Generally, assessment can be used in the process of instruction to evaluate learners’ learning efficiency, skills and knowledge. With the evaluation of assessment results, instructors can judge learners’ learning efficiency and ability; besides, students can find out whether they acquire the learning material completely or partially. In order to provide a rich internet application with AJAX, the purpose of this research is to construct an adaptive, reusable and sharable assessment system. AJAX is a novel technology used in rich-client web applications recently. It employs an asynchronous communication way and provides users with better experiences. Thus, we propose an on-line adaptive testing system, which provides the QTI standardized items and adaptive assessment mechanism, and combines the Web 2.0 concept. The system integrates the Question and Test Interoperability (QTI) Version 2.0 proposed by IMS Global Learning Consortium.
