Abstract: Computer programming is a difficult skill for many students and visualizations may be used to foster learning. This paper presents a program animation system, PlanAni, that is based on the concept of the roles of variables. Roles represent schematic uses of variables that occur in programs over and over again, and a set of nine roles covers practically all variables in novice-level programs. PlanAni has been tested in a teaching experiment comparing traditional teaching with role-based teaching and animation. The results of a semi-structured interview with the teacher indicate that students like to work with the animator and that the system clarifies many concepts in programming.
