摘要:	在遠距教學的媒體中，雙向視訊會議能使學生與教師進行面對面的溝通，同時也是最接近傳統教室上課的型態，但常因種種系統、教室環境的設計，不能符合教學所需，而失去視訊會議媒體在提供高臨場感上的特性。因此本研究嘗試設計一個數位教室環境，利用系統整合PTZ(pan/tilt/zoom)攝影機及大螢幕，使遠端學生能遙控PTZ攝影機來觀察、掌握教室中的情形，而教室師生能透過大螢幕來觀察遠端學生的情形。希望藉此提高雙向視訊遠距教學中的臨場感，並達成在雙向視訊遠距教學中進行小組合作學習。研究結果顯示，使用PTZ攝影機及大螢幕的數位教室環境，能提升遠端學生感覺像出席在教室的遠距臨場感，而不是只是在遠端盯著螢幕上課而已。亦能提升遠端學生和教室端師生之間，感覺像是在一起上課的社會臨場感，使遠端學生能自然地與教室師生進行互動。 In the media of distance learning, two-way videoconferencing can let students and teachers establish face-to-face communication, at the same time it is the type most close to traditional classroom lecturing. Nevertheless, sometimes due to the design of system and classroom environments cannot fit in with the needs of teaching, it loses the characteristic of videoconferencing in offering high presence. Therefore, this research tried to design a Digital Classroom Environment by integrating PTZ (pan/tilt/zoom) camera and large screen to let the students control the PTZ camera remotely to observe the situation in the classroom. In addition, local teacher and students can observe the situation of the remote students through the large screen. We hope to improve the presence of the two-way videoconferencing distance learning, and achieve group’s collaboration learning in the two-way videoconferencing distance learning. The results of the research show that the Digital Classroom Environment with PTZ camera and large screen can improve the telepresence of the remote student to feel being present at the classroom, and not just watching the screen having lecture at the remote side. In addition, it can improve the social presence of the remote students and the local teacher and the local students to feel being having a class together, and it let the remote student interact naturally with the local teacher and the local students.
