摘要


本研究旨在探討擬真遠距學習模式及系統的設計。本研究進行了三個研究實驗來研究這個課題:(1)即時課程錄影及線上同步廣播系統在遠距教學上之應用,本系統結合了Windows Media Services的技術和搭配Moodle學習管理平台應用在遠距教學上,讓學習者能透過本系統學習錄影課程或是即時觀看遠端教室的授課內容。透過錄影課程,讓學習者能反覆的觀看授課內容,增加對授課內容之理解與記憶。(2)利用視訊會議技術於遠距互動學習,旨在利用視訊會議技術讓教導者與學習者能透過此系統,進行遠距互動輔助學習。此研究主要藉由多媒體學習,探討老師在授課中非語言成分的行為是否能增加學習效果的方法。其中非語言的行為包含了老師的眼神與肢體行為的表現。而研究的結果發現在課程錄影畫面中增加老師非語言成分的行為對於學生的學習有顯著的結果。(3)建構線上讀書會結合社群網站系統,透過小組學習,以提高學生的閱讀能力和學習成效。學生可以在線上與小組成員立即分享閱讀的經驗,或是與其他學生透過社群網站進行知識交流。此研究透過問卷施測方式發現,利用線上讀書會結合社群網站系統不但可以增加學生閱讀的技巧,也能增進團隊合作的默契。 本研究希望藉由上述三個研究實驗去模擬真實教學環境,讓學習者可以在任何地點都能進行學習,也可透過互動視訊會議平台,去和指導者探討學習過程中之疑惑,最後利用多媒體教材設計系統,重整所學的知識,在語意的表達和內在知識的轉換中建立出一套屬於自己本身的長期記憶(long-term memory),讓知識經過重整的活動真正吸收而達到學習目的。

The purposes of this thesis are to explore the system analysis and design of Virtual Reality Model for distance learning. The study conducted three experiments to study the issue: (a) e-Broadcasting system with application in distant learning. The system is proposed to combine the technique of Windows Media Services with Moodle in order to apply in distance learning for learners to learn pre-recorded course or watch the live teaching content of remote classroom; and further, it is increased the understanding and memory of the content in class by watching repeatedly. (b) The primary goal in this experiment was to find out a method to increasing the effect of multimedia learning in the classroom. The nonverbal components of teacher in the classroom were the instrumentality in this experiment to accompany with multimedia. The video capturing device captured the image of teacher especially in teacher’s facial expression and eye-contact as the nonverbal components transformed in multimedia signal. The system integrated the signals including learning content and teachers’ image and projected in the large classroom for every student in the lecture class. The outcome of this study reflected the significant progress in students’ achievement as compared to lecture class with PowerPoint only. (c) The experiment proposes an online reading system that incorporates group study, called the OGS system, to enhance student reading ability and learning effectiveness. With the OGS system, a student can immediately share the experience of reading e-books with other group study students. Students can also use an online social network for the exchange of knowledge with other students. Teachers can provide guidance before students read or during the reading process. After the conclusion of group study, teachers and students can review their portfolios during this online social network meeting to discover deficiencies in their activities. The results revealed that the OGS system is helpful to students in terms of reading skills, cooperative learning, and friendship. This research hopes to imitate the true teaching environment with three experiments described above and enable learners to study in any place. With the platform of video conference, students and teacher probe into the doubt in the learning process. Utilized system that the multimedia teaching material is designed finally, students can restructure the knowledge they learned and achieve the purpose of studying.
