Students' Computational Thinking Process in Solving PISA Problems of Change and Relationship Content Reviewed from Students’ Self Efficacy

This research focuses on the stages of students' computational thinking processes in solving PISA questions about change and relationship content terms self-efficacy. The subjects this study were 15-year-old students class X MIPA 3 MAN 1 Semarang City, totaling 22 selected 2 who had high self-efficacy, moderate self-efficacy low method uses a qualitative descriptive approach. Data collection using questionnaires, test instruments interviews. analysis included data collection, reduction presented text form drawing conclusions or verification. results show that have can reach decomposition, pattern recognition, abstraction algorithmic as well thought carrying out plans link real problems into mathematical problems. Whereas are reaching do not connect to but use logic. only decomposition recognition done because logic these provide answers logical steps
