Presents two short microcomputer programs which illustrate features of nonlinear dynamics, including steady states, periodic oscillations, period doubling, and chaos. Logistic maps are explained, inclusion in undergraduate chemistry and physics courses to teach nonlinear equations is discussed, and applications in social and biological sciences…

Based on the results of an assessment of 241 teaching-learning programs in biology, chemistry, physics, general science (primary level), and informatics, this article discusses possible criteria for the assessment of educational software. Offers suggestions for potential users, for practitioners of teacher education, and for the developers of…

This first of two articles presents eight examples of what software infusion (SI) looks like in actual practice in elementary, middle, and high school classrooms and learning laboratories. An analysis of SI characteristics demonstrated in the examples is presented to bring the definition of SI into focus. (MBR)
