Multimedia access platform for virtual learning environment

摘要

A virtual learning environment (VLE) is a set of integrated teaching and learning tools designed to enhance a student's learning experience. Over the last decade, a number of VLEs have been developed and adopted by universities and even high schools. However, we note that the majority learning materials in VLEs are still text-based and multimedia has not been effectively explored in existing VLEs. In this paper, we propose a multimedia access platform for VLEs. A good multimedia access platform should provide efficient access mechanism, interactive learning environment, and rich and relevant learning material at appropriate time. Based on the proposal, multimedia access platform for virtual conferences (MAPVC) has been implemented. This platform integrates videos, PowerPoint slides, HTML files and other public domain data into structured multimedia learning material, which supports random access and flexible search, and optimizes learning by presenting learning materials in multiple channels and at appropriate time.
