非同步遠距教學已成為重要的教學趨勢，但教師在實施非同步遠距教學時，無 法確切的掌握學習者的學習狀態，且網路上的誘惑很多，使學習者無法專心於學習課程。開 發一個能實際了解學習者學習狀態的追蹤系統便成為網際網路非同步遠距教學系統中管理與 評估學習效果的重要課題。但由於目前的非同步追蹤系統均架構在瀏覽器之內，無法跳脫視 窗的囹圄，來記錄其他視窗的學習狀態，以致不能反應出學習歷程的真實性。再者，目前的 追蹤系統只限於自行開發的網站上，對於廣大的網際網路來說，作用相當有限。因此，本論 文旨在發展一套較適切的追蹤系統，並利用本系統記錄學童們在網頁課程上的學習歷程，我 們以144名國小高年級學生為研究對象，採相關研究法進行研究。研究發現：網路學習歷程 記錄中的網路學習時間、相關網頁數且及滑鼠移動次數均與網路學習效果有非常顯著的正相 關；狀態列改變次數與網路學習效果也有顯著的正相關。但在網路學習效果的預測方面，只 有網路學習時間具有非常顯著的預測效果。

　　　　　Although distance learning becomes a tendency, teachers usually fail to take good control of the learning situations of students Meanwhile other attractions on Internet usually keep students from being concentrated on their learning Therefore, to establish a tracking system that can actually catch on students' situation has become a subject matter for distance learning Such a tracking system that can actually catch on students' situation has become a subject matter for distance learning Such a tracking system plays an important role of controlling and evaluating the effect on distance learning However, current tracking systems, which are constructed inside browsers and confined to window systems, are unable to monitor the learning situation in other windows Therefore, the actual learning process cannot be revealed Moreover, current tracking systems are confined to their self-developed websites; as to the vast Internet, the functions of the tracking systems become rather limited Therefore, in this paper, we develop a more efficient and useful tracking system and also study the effect of learning achievement by learning histories of the 144 sixth/fifth graders of primary school. It is found that the effect on internet learning is significantly and directly correlated to time spent on learning, quantity of related homepages, and numbers of times for moving mouse etc, which are all recorded in trainees' learning history Besides, it is also noteworthy that the effect on learning has an important correlation with the number of times for changing the status bar.
