This article describes the initial development of a qualitative system dynamics model as part of the periodic review of a mathematics course. In an effort to enhance the learning experience of undergraduate computing students (for whom the course is a compulsory part of their curriculum) a small sample of students were interviewed regarding their…

Nondeterminism is an essential concept in mathematics and one of the important concepts in computer science. It is also among the most abstract ones. Thus, many students find it difficult to cope with. In this article, we describe some didactic considerations, which guided the development of a "Computational Models" course for high school…

SIGMA (Simulation Graphical Modeling and Analysis) is a computer graphics environment for building, testing, and experimenting with discrete event simulation models on personal computers. It uses symbolic representations (computer animation) to depict the logic of large, complex discrete event systems for easier understanding and has proven itself…
