New approaches to emergent learner-directed learning design can be strengthened with a theoretical framework that considers learning as a dynamic process. We propose an approach that models a learning process using a set of spatial concepts: learning space, position of a learner, niche, perspective, step, path, direction of a step and step…

Too often, organizations make the mistake of treating malware infections as a series of independent occurrences. Each time a malicious program is discovered, IT simply cleans up or rebuilds the affected host, and then moves on with routine operational tasks.

Conflicts occur when learners interact with pedagogical agents and virtual characters. Such conflicts--arising from technological limitations, psychosocial perceptions, and pedagogical inadequacies--hinder communication and interaction between virtual characters and learners, and impede successful engagement with learning tasks and experiences. To…

Discussion of information systems methodologies that can contribute to interface design for public access systems covers: the systems life cycle; advantages of adopting information systems methodologies; soft systems methodologies; task-oriented approaches to user interface design; holistic design, the Star model, and prototyping; the…
