Google Docs and Skype for a Low bandwidth virtual classroom for developing countries

There has been much attention recently on the use of virtual classrooms to support distance learning. However, the required real-time and high-rate transfers for multimedia contents such as video and audio that comprise most off-the-shelf virtual classrooms make them infeasible for developing countries where bandwidth is typically more restricted. This paper describes the findings of an ongoing investigation to develop a low bandwidth virtual classroom that can provide the necessary functionality to deliver courses to distant students. By combining Google Docs and Skype, we realised a low bandwidth virtual classroom alternative that could provide adequate functionality within our teaching context.
