Zusammenfassung
The increasing importance of programming skills for various professions highlights
the necessity of laying solid foundations for these skills in school. One critical step when learning
programming is code tracing, i.e., the ability to analyze program code to predict the data changes
when the code is executed. Considering the diverse levels of prior knowledge in computer science
classes, it is essential to implement tailored teaching approaches, which can enhance the respective
learning outcomes. To create personalized learning paths, we developed the tutoring system Feedback
Buddy that teaches if-else branches, for loops, and combinations of them using tracing tables. Thereby,
the Feedback Buddy adapts its feedback and task difficulty based on learners’ affective, cognitive, and
metacognitive states. Extending former systems, our approach focuses on school education and uses
𝑡h growth mindset feedback. Evaluation with 10
positive results, affirming the usability and usefullness of the Feedback Buddy in secondary school education.
