This article presents the design and evaluation of a tool for inspecting conceptual models of system behaviour. The basis for this research is the Garp framework for qualitative simulation. This framework includes modelling primitives, such as entities, quantities and causal dependencies, which are combined into model fragments and scenarios.…

Examines four working steps from an empirical model where an expert abstractor discovers what a paper is about and drafts a topic sentence; a simulation system is developed using this model. Discusses knowledge processing activities of professional summarizing. Results indicate that a small simulation model of professional summarizing is feasible.…

Compares dyads of secondary school physics students working on a collaborative modeling task using a text-based model representation, in which correct equations are required to make the model run, with others using a graphical representation, in which the model is build by qualitatively linking variables.

Advances in computers and multimedia technology have changed traditional methods for learning and skills training. Online learning continues to play a major success of any academic program. Such learning can personalize learning needs for students, it can provide an environment where virtual reality techniques are used to create interactive…
