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)
With the aim to facilitate sharing and uptake of high quality JCT-based learning designs amongst academics in higher education, the Australian Universities Teaching Committee fimded project: Jnformation and Communication Technologies (leTs) and Their Role in Flexible Learning examined a number of existing high quality, JCT-based learning implementations to(More)
The concept of information landscapes has been a constant theme in the development of interactive multimedia packages. For the interface and access to this information to be effective and efficient, consideration must be given to the cognitive load placed on the user. Improvement in learning outcomes can be supported by allowing students to focus on(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)
This paper presents a quantitative approach to multimodal discourse analysis for analyzing online collaborative learning. The coding framework draws together the fields of systemic functional linguistics and Activity Theory to analyze interactions between collaborative-, contentand technology-related discourse. The approach is used to examine how the task(More)
For educational software to take advantage of contemporary views of learning, instructional designers need to employ design models that incorporate the variety of ideas that are based on constructivist frameworks for developing learning environments. These environments, if well designed, can support learner construction of knowledge, however such frameworks(More)
