Code quality is a critical aspect of programming education in K-12, as it notably affects students’ understanding of code and their ability to modify code. This poster presents a research project aiming at fostering code quality in K-12 education. As a first step, we explore several activities applied in educational contexts, like refactoring, using a linter, or performing a code review. The findings of this short review implicate that active participation in these activities has the potential to foster good programming habits.
