Recast Common Multimedia Classrooms to Remote Interactive Classrooms//Chen Wangsheng

Abstract In this text, it is briefly presented and discussed that the difficulties to share real-time class-teaching among colleges’ classrooms at present. To achieve the objective of sharing the real-time resources, it is considered to recast common multimedia classrooms to meet the needs of remote interactive classrooms. Then based on the current system of multimedia classrooms, a recast plan is introduced and analyzed through for its feasibility. After putting the classrooms’ recast into practice and test carefully, it is shown that the recast classrooms meet the needs of real-time remote interactions, and the recast is very simple in technique and cheap in budget.

Key words multimedia classroom; networked central controller; real-time resources sharing; remote interaction

1 引言

隨著多媒體教學應用係統的日益普及,一大批優秀的多媒體教學資源在各高校相繼建立,但如何實現課堂資源的實時共享卻始終是資源管理的一個難點。這個問題不但在多校區高校存在,在各校區內部也同樣會有。尤其是在優秀公共課程的設置上,各大高校不僅希望能夠開放課堂以滿足校區內的選修要求,更希望能在跨校區間遠程互動開放,以在更大範圍實現資源共享的目標[1-3]。

考慮到目前教室座位資源配置的緊張狀況,孤立教室的課堂開放基本上難以滿足需求,遑論跨校區的遠程課堂共享。市麵上雖有一些公司提出建設多教室聽課係統方案,但這些專用係統不僅造價高、遠程實時互動能力差,且往往和現有多媒體中控係統不兼容,不太符合高校的實際應用條件。

有鑒於此,綜合各高校與華僑大學實際情況,考慮將網絡中控多媒體教室改造為遠程實時互動教室以滿足需求。改造方案既要充分挖掘現有多媒體教室係統的資源潛力,又要和現有係統兼容,還要滿足低預算、易實現的要求。
