Online Virtual Learning Environments: A Review of Two Projects

摘要

This article is an overview of online virtual learning environments for discovery learning. The paper defines Virtual Learning Environments and discusses literature findings on the benefits of using web-based VEs for self-directed learning. It gives an overview of the latest technologies/platforms used to develop online VEs, discusses development and delivery challenges posed by complex, information-rich web-based 3D environments, and describes possible solutions that can be adopted to overcome current limitations. The paper also presents and discusses two 3D web-deliverable virtual learning environments that were recently developed by the authors: the "Virtual Tour of the Muscatatuck State Hospital Historic District (MSHHD)" and the " VELS: Virtual Environment for Learning Surveying ". The "Interactive 3D Tour of MSHHD " is a web-based digital heritage application that uses Virtual Reality as a tool to document and preserve historic sites and educate the public about them; the "VELS" is an online virtual learning environment whose objective is to help undergraduate students learn surveying concepts and practices.
