應用互動式隨選系統於遠距教學之研究

Abstract

本研究為建立一互動式隨選視訊遠距教學系統之雛型，模擬從教學者編製 教材到 使用者經由有線電視進行遠距離教學之整個流程。系統包含 兩個主要部份：教材編輯系統與教學展示系統，教材編輯系統負責將課程 與教學影帶所提供的參考資訊作一些記錄 ，供教學展示系統在執行時的 參考，而教學展示系統則是模擬電視畫面，展示學生使用此系統時教學的 過程。在論文中我們詳細介紹以互動式隨選視訊（Interactive Video On Demand）環境下的遠距教學(Distance Learning)，並利用互動式隨選視 訊應用於遠距教學的理論與方法，設計了一套雛型系統，輔以視訊按鍵( VideoBoard Click)的作法，提高VOD的互動性，期使學生在經由有線電視 學習遠距教學課程時，不但能保有傳 統教學的特性：老師講課、學生 隨堂疑問及解答、課後練習及測驗等優點，又能依自己的生活及工作習慣 決定上課時間、方式及地點。 This thesis presents a application based on Interactive Video On Demand( IVOD)for distance learning. To simulate the whole progress from the editor of coursematerials to students learn through cable TV. The system includes two main components: It's course editor system and teaching demo system, course editor system take the reposes for data recording from course resource, video tape.Teaching demo system demos students run system to learn course through TV screen. In this thesis , We introduce Distance Learning under Interactive Video On Demand in detail, By the way we design a new system of pplication modal which is based on Videoboard Click by using the methodology of distance learning in IVOD, to improve the interactive efficiency. We expect the students( users) would obtain the merit of distance learning through cable TV. Not only users can get original benefit from classical traditional teaching style but also create the merit and characteristics, which consist of 1. Lecture, 2.Questionand answer, 3. Homework, 4. Exam test.. etc., 5. Flexiblelesson time place.
