Analysis of students' computational thinking skills in science and mathematics subject in fifth grade of elementary school

Introduction: This study aimed to explore the components of computational thinking skills at the End of Term Summative Assessment (ETSA) and End of Year Summative Assessment (EYSA) questions as well as the profile of computational thinking skills in science and mathematics subjects of fifth-grade students in Surakarta City, Indonesia. Method: This was a qualitative study with a case study approach. Data were collected through analysis of ETSA and EYSA documents, which include test instruments and student answers. Sampling was carried out using purposive sampling by considering the level of cognitive development of students. Results: The results showed that each ETSA question included components of decomposition, pattern recognition, abstraction, and algorithm design. Meanwhile, each EYSA question included different components from one question to another. The profile of students' computational thinking skills showed variation in the success of answering questions, with significant differences between components and types of questions. Conclusions: This study concludes that ETSA questions are more consistent in covering all components of computational thinking skills compared to EYSA. The profile of student skills varies, with some components showing lower results. The implications of these findings include the need for adjustments in the curriculum and teaching methods to emphasize more evenly distributed mastery of computational thinking skills. Further research should explore the causes of variation in mastery of these skills and develop more comprehensive evaluation instruments.
