Hsu, I-Ching – Educational Technology & Society, 2012
The concept of learning objects has been applied in the e-learning field to promote the accessibility, reusability, and interoperability of learning content. Learning Object Metadata (LOM) was developed to achieve these goals by describing learning objects in order to provide meaningful metadata. Unfortunately, the conventional LOM lacks the…

Schofield, Damian – Journal of Information Technology Education: Research, 2014
Advanced three-dimensional virtual environment technology, similar to that used by the film and computer games industry, can allow educational developers to rapidly create realistic online vir-tual environments. This technology has been used to generate a range of interactive Virtual Real-ity (VR) learning environments across a spectrum of…

Clark, Douglas B.; Sampson, Victor – Journal of Research in Science Teaching, 2008
The national science standards, along with prominent researchers, call for increased focus on scientific argumentation in the classroom. Over the past decade, researchers have developed sophisticated online science learning environments to support these opportunities for scientific argumentation. Assessing the quality of dialogic argumentation,…

Barnard, Philip J.; May, Jon – Human-Computer Interaction, 1999
Interacting cognitive subsystems (ICS) is proposed as a unified cognitive theory that can be used as the basis for representations in human-computer interaction, and two approaches based on the theory are described: one entails the description of cognitive task models, and the other entails the production of less complete diagrammatic notations.…

Hypermedia Representations for Learning: Formal and Informal Observations on Designs and Directions.
Parkes, A. P. – 1994
This paper focuses on issues of representation and interaction styles that are relevant considerations in the design and analysis of hypermedia learning environments. Analysis is supported by examples from the "HUGH" series of studies involving learners in reasoning about formal hypermedia representations. The representational issues include…

Frick, Theodore W. – Journal of Educational Computing Research, 1997
Maccia's epistemology of intelligent natural systems implies that computer systems must develop qualitative intelligence before knowledge representation and natural language understanding can be achieved. Emotion and sensation--capabilities which computers do not currently possess are vital to the growth of the mind (Stanley I. Greenspan).…
