Effect of using computer graphics animation in programming education

The authors developed a novel lecture style for elementary programming education named program reading practice by using computer graphics animation programs (named WinTK). In this practice, students read the source codes of various kinds of computer graphics animation programs and are challenged to modify or extend these programs instructed by the teacher (program re-write practice). We have done this practice for six years and investigated various kinds of results in order to acquire the effect objectively. The authors describe the investigation technique and several results of our practice.
