Motivated by a desire to apply Computer Science and Virtual Reality (VR) technology due to the need for improving secondary school education in Malawi, this paper presents a prototype of a synchronous multi-user cross-platform real-time 3D VR application. This tool can be used by VR application developers in assessing the feasibility of using VR technologies for secondary school teaching in Malawi. The prototype VR application illustrates the capabilities of the proposed development tools, as well as how the proposed technologies can be utilized in a design and implementation that accounts for the context of Malawi, where access to electricity and internet services are a challenge for many.
