Learning Support System Visualizing Relationships Among Classes and Objects Based on Teacher’s Intent of Instruction

Abstract

While several learning support systems that visualize program behaviors for various object-oriented languages have been developed to date, many of them are not sufficient for learners to understand the concepts specific to object-oriented languages. We have developed a program visualization system that supports learners' understanding by visualizing relationships among objects and classes. We evaluated the effectiveness of our system by introducing it into an actual class and measuring the degree of improvement in learners' understanding based on tests. The evaluation results suggest that our system would have a certain degree of effectiveness for learning programming using object-oriented languages.
