GUI Based Environment to Support Writing and Debugging Rules for a Program Visualization Tool

Abstract

TEDViT is a program visualization tool that allows teachers to apply an intention of description (IOD). Using this tool, teachers write a rule set to apply IOD. However, it takes a relatively long time to write the rule set. In this paper, we measure the amount of time required to write rule sets by conventional interface. We determine the reasons why it takes long time and suggest solutions. Thus, we constructed a supporting system that has features corresponding to these solutions. Our experimental results show that the system reduces total writing and debugging time by 41%.
