A Program Transformation Tool for Visualizing Control Structure in Graphical Representations

Abstract

In this paper, we describe a work-in-progress research to develop a program control structure visualization tool for transforming student programs into graphical representations of control structure, including sequences, selections, and iterations. The tool can be used for assisting novice students in debugging their programs by checking whether the transformed control structure of their programs is consistent with their program plans. In addition, the graphical representation of student programs can be compared to that of a model program to detect errors in program plans.
