A Proposal for a Debugging Learning Support Environment for Undergraduate Students Majoring in Computer Science

Abstract: In software development, encountering bugs is inevitable. However, opportunities to learn more about bug removal are limited. When students perform debugging tasks, they often use print statements because students do not know how to use a debugger or have never used one.In this study, among various debugging methods, we focused on debugging using breakpoints. We implemented a function in Scratch, a visual programming language, that allows for self-learning of correct breakpoint placement and systematic debugging procedures.In this paper, we discuss experimental results that clarify the changes that occur in subjects when they learn debugging in Scratch.
