With the aim to facilitate sharing and uptake of high quality ICT-based learning designs amongst academics in higher education, the Australian Universities Teaching Committee funded project: Information and Communication Technologies (ICTs) and Their Role in Flexible Learning examined a number of existing high quality, ICT-based learning implementations to(More)
Teachers in a range of disciplines are interested in engaging their students in authentic activities that reflect the experiences of real-world practitioners. Adopting this approach requires the design and implementation of learning environments that incorporate and support such activities. This paper describes two real-life cases developed as support(More)
This paper explores the potential learning benefits of 3D Learning Environments (3DLEs). It presents definitions of key terms and analyses the learner-computer interactions facilitated by 3DLEs, in order to identifj! the unique characteristics of such environments It is argued that the most important potential contribution of 3DLEs to conceptual(More)
This paper describes G-Portal, a geospatial digital library of geographical assets, providing an interactive platform to engage students in active manipulation and analysis of information resources and collaborative learning activities. Using a G-Portal application in which students conducted a field study of an environmental problem of beach erosion and(More)
The personalized project space is an important feature in G-Portal that supports individual and group learning activities. Within such a space, its owner can create, delete, and organize metadata referencing learning objects on the Web. Browsing and querying are among the functions provided to access the metadata. In addition, new schemas can be added to(More)
Learner construction of their understanding is one of the basic tenets of a constructivist framework of learning. Technology-supported learning environments have been developed to support construction and allow students to employ resources to express their ideas and arguments. A new product, StageStruck, has been developed to extend the process of knowledge(More)
