Analisis Kemampuan Pemecahan Masalah Matematis Siswa Kelas IX SMP Negeri Oemasi pada Materi Teorema Phytagoras

Abstract

This study aims to describe students' mathematical problem-solving abilities in solving Pythagorean theorem problems. This study was conducted at Oemasi State Junior High School in the 2024/2025 academic year, even semester. The subjects in this study were 19 students. The research instruments used were test questions on conceptual understanding and mathematical problem-solving abilities. The research method used was a qualitative research design. Data were analyzed using data reduction, data presentation and drawing conclusions. Based on the results of the study, it can be concluded that students who have high-level problem-solving abilities are students who can work on and explain what has been done according to the existing problem-solving stages, while students who have moderate problem-solving abilities are students who can solve half of the questions given and can explain them again according to the stages of the questions that have been worked on and for students who have low-level problem-solving abilities are students who can only understand the problem in the question but to carry out the solving process to the final stage or completion have not been able and have not been able to explain what has been done.
