Analysis of computational thinking ability based on PISA problems viewed from numeracy ability

This study aims to explore and dissect the ability of computational thinking in solving PISA-based problems on the content of change and relationship in terms of numeracy ability. Numeracy ability, which is grouped into high, medium, and low is very efficient to use to analyze the ability of computational thinking. The method used in this study is descriptive research with a qualitative approach, the subject of this research is class VIII students of SMP N 1 Tasikmadu. The analysis technique used is data reduction, data presentation, and drawing conclusions. The instruments used in this research are the numeracy test questions, computational thinking test questions, and interview guidelines. The result of this study show that student with high numeracy ability is able to fulfill aspect of decomposition, pattern recognition, abstraction, and algorithmic thinking. Medium numeracy ability can fulfill aspects of decomposition, pattern recognition, and abstraction, while low numeracy ability can only fulfill aspects of decomposition and pattern recognition.
