Kemampuan Penalaran Matematis dan Computational Thinking Siswa SMP dalam Penerapan Prinsip Pembelajaran PISA

Mathematical reasoning and computational thinking skills are crucial 21st century skills. However, the results of international studies show that these abilities are still low in Indonesian students. This study aims to test the effectiveness of PISA principle-based learning in improving mathematical reasoning and computational thinking skills of junior high school students. This study used a quasi-experimental design with two groups of seventh grade junior high school students as subjects. The experimental group received a PISA principle contextual based learning method, while the control group followed a conventional learning method. The research instrument was a mathematical reasoning and computational thinking ability test. Data were analyzed using the Hotelling T2 test to describe the effect of learning methods on students' mathematical reasoning and computational thinking abilities and the t-test to describe the effectiveness of contextual-based PISA learning methods reviewed from mathematical reasoning and computational thinking abilities. The results showed that there was an effect of learning methods on students' mathematical reasoning and computational thinking abilities, the contextual-based PISA principle learning method was effective in terms of students' mathematical reasoning abilities but not effective in terms of students' computational thinking abilities. This can be a reference for educators and policy makers in designing mathematics learning that is more relevant to the demands of the 21st century.
