Building Bridges : Combining Webcasting and Videoconferencing in a Multi - Campus University Course

Supporting lifelong learning can be challenging in that participants are often geographically distributed, have significant time constraints, and widely varied skills and preferences with regard to technology. This creates the need for designers to support flexible configurations of systems for delivering content, in ways that still allow for meaningful learning and instruction to take place. In this chapter, the authors present a case study of experience in offering a university course using a novel system that bridges videoconferencing and webcasting technologies. These have historically been separate. Webcasting scales easily to accommodate large audiences, but only supports one-way transmission of audio and video. Videoconferencing allows for two-way interaction in real time, but uses more bandwidth, and does not scale as easily. Our system allowed for increased participation in webcasts, which had benefits for both DOI: 10.4018/978-1-61520-983-5.ch009 Co py ri gh t © 2 01 1. I nf or ma ti on S ci en ce R ef er en ce .
