線上多媒體英文寫作與即時批改系統

近年來各式線上英文作文批改系統不斷地推陳出新；但大部分的系統都無法提供教師及學生即時互動的功能。為解決這個問題，我們發展一套新的英文作文批改系統，當教師批改學生的作文時，學生可以遠端即時地看見教師批改的情況，並且可以與教師討論問題。如此一來，學生可以在批改的過程中即時地提出問題；本系統也能把批改過程中教師的講解與批改的註解完整地保存下來，便於學生日後複習。此外，本系統亦提供一對多的教學形式，可以讓一個老師同時對多個學生教學。我們的系統提供了一個可以同步語音與批改事件的平台，由於這個系統注重學生端與老師端的互動，所以對於網路流量及系統反應速度的要求較為嚴苛，希望可以讓使用本系統的學生能夠有教師在身旁指導寫作般的即時互動。

並列摘要

In recent years, although many kinds of online English compositions correcting systems have been constructed, most of them do not provide live lecture function. To solve this problem, we design a system in which students can immediately watch the compositions correcting process and directly propose their own questions for obtaining teachers’ instruction while they are confused in writing. Our system also provides a broadcast model in which one teacher can deliver a live lecture for several students at the same time. It not only provides students with a live lecture function but also provides a review function. By this review function, students can review the whole correcting process after the live lecture. Our system provides a platform which can synchronize the voice and correction events. Because this system is a real-time network application, we have to face the challenge in network bandwidth.
