This article describes a calculus lesson that illustrates the nature of cycles in simple systems of nonlinear differential equations through the use of the Lotka-Volterra predator-prey model as incorporated in the computer software package, Phaser (version 1.0). (JJK)

This review features new examples of using the computer relative to college-level mathematics to enhance pedagogy, solve problems, and model real-life situations. Included is a LOGO program that can be used to create and to stimulate subsequent investigations of spirolaterals, those figures generated by repeatedly drawing basic loops. (JJK)

Presented is a detailed review of eight computer software packages. Strengths, weaknesses, and recommendations for each game are listed. Mathematical and thinking skills, problem solving, drill and practice, procedural activities, decision making, understanding money, and basic skills are emphasized. (KR)
