以VNC建置電腦教室廣播系統

本研究使用開放源碼VNC (Virtual NetworkComputing) 遠端控制系統，設計成教學軟體廣播系統。本系統於VNC 伺服器架設互動及只能觀看兩種模式，老師機以互動模式登入進行操作示範；學生機則以只能觀看模式登入觀看老師示範。VNC 客戶端並不會鎖定作業系統的操作，所以老師仍然可以進行其他工作，學生也可以邊看老師示範邊跟著練習。為了提升系統可攜性，本系統同時架設noVNC，VNC 客戶端不需要安裝VNC viewer套件，使用網頁瀏覽器就可以連線VNC 服務進行操作或觀看。本系統已實際使用於朝陽科大E-517 電腦教室多學期，若VNC 伺服器使用實體IP，更可進行遠距教學，讓電腦教室以外的學生一起學習。

This study design the Broadcast Teaching System using open source software VNC (Virtual Network Computing) Remote Control System. The VNC server has two modes, interactive and viewonly, the teacher demonstrates in the interactive mode, and the students view the teacher demonstration in the view-only mode. The VNC client does not lock the operating system, so the teacher can still do other work, and the student can see the teacher and follow the exercises. If the VNC server using fixed IP, this system can also be used distance learning, enable remote students to learn outside the classroom together.
