摘要：Roles of variables, which describe stereotypic usages of variables, can be exploited to facilitate
teaching introductory programming. This paper describes the evaluation of visual metaphors for
roles used in a role-based program animator. The evaluation is based on several criteria: properties
of the images, metaphor recognition and grading, and effects on learning. The study demonstrates
that as a whole the role metaphors facilitate learning. The results also identify ideas for
further elaboration of the individual metaphors. Furthermore, the study suggests that the evaluation
of animated metaphors may require special measures.
