The construction and reconstruction of meaning by learners
requires that they actively seek to integrate new knowledge with
their existing cognitive structure.
Our research program has focused on leveraging the convergence
of technologies that underlie current approaches to computer-based
learning, distance learning, performance support systems, WWW
browsers, collaboration tools, and just-in-time training to develop
software tools and methodologies that support and foster meaningful
Using concept mapping and PBL (problem-based learning) as the
underlying methodologies, these new technologies will enhance
learning by novices and experienced workers. Applications cover
a broad spectrum, from pre-school to universities, Navy just-in-time
performance support and training for sailors on a ship to knowledge
dissemination from retiring experts.
