摘要

近年來隨著網際網路與數位學習的興起，學習型態也隨之轉變。學習教材整合文字、圖片、聲音與影像動態的呈現出來，促使知識的加速傳播，學習者不再只是被動的接受知識，也可以主動地相互分享知識；學習的過程中透過「做筆記」、「寫註解」、「標記重點」等方式，可以增進思考、加深學習的記憶，因此在數位學習上做學習的註解也是相當必要的。學習者在影片內容中的某些時間區段或特定的畫面內容加入適當的註解並將之分享是很重要的，不但讓整個影片的瀏覽更有效率，知識的分享也能讓學習者間清楚地了解影片內容的重點所在。本研究將影片註解結合知識迴旋模式，建構一個針對影片內容的編輯註解與分享系統，支援學習者在影片的學習過程中能隨時對影片內容做畫面的標記與註解，並且讓學習者間的註解知識能分享與傳遞，藉由影片的註解功能與學習知識的獲取、分享、創新、擴散等知識的轉換過程，為以影片為學習型態的數位學習帶來更高的學習效益。

An increasing number of users are turning to the Internet to make their learning. Dynamical techniques (text, picture, voice, and video) are now embedding in teaching materials to accelerate the sharing of knowledge. This represents that users would no longer play a passive role to receive the knowledge, they share the learned knowledge in an active way. It is important to add the annotation into e-learning since the capability of thinking and memory could be improved by “noting”, “annotating” and “highlighting”. On the other hand, if the user could add annotations into the specific video frame, it would be helpful to browse the video efficiently and further increasing the knowledge sharing. Unfortunately, this emerging concept of video annotation is seldom mentioned in past decade but it will be a trend in the future. Therefore, this research embeds the annotation into video environment followed by the knowledge spiral model. The research to develop a Video Annotation and Knowledge Sharing System and brings several advantages to the user. Users can make annotations anytime they want during playing the video. Realizing the knowledge spiral by video annotation creating, acquiring, sharing and diffusing annotations. Video annotation is a new addition to extend the scope of e-learning and improves the learning efficiency.
