How Do Elementary Students Apply Debugging Strategies in a Block-Based Programming Environment?

Debugging is a growing topic in K-12 computer science (CS) education research. Although some previous studies have examined debugging behaviors, only a few have focused on an in-depth analysis of elementary students’ debugging behaviors in block-based programming environments. This qualitative study explored the debugging behaviors of four students, including their strategies and challenges. The study employed thematic video analysis of students’ computer screens as they engaged in block-based programming activities. The findings reveal five types of debugging strategies and three primary challenges during the debugging process. This study aims to help researchers and educators understand elementary students’ debugging strategies and the challenges they face. Suggestions for teaching debugging strategies to elementary students and the implications for future research are discussed.
