Abstract

This study aims to describe and analyze the mathematical spatial ability of junior high school students in grade 8 in solving Pythagoras questions. This type of research is case study research with qualitative approach and using descriptive qualitative research design. Determination of research subjects using probability sampling and then obtained 1 student from 33 students who were used as research subjects, namely Participant 1 (P1). Research instruments in the form of spatial ability tests that have been validated and meet the rules of instrument writing for research. Data collection in this research is observation, test, interview, and documentation. Data analysis includes data reduction, data presentation, and conclusions. The validity of the data uses triangulation techniques. P1's mathematical spatial ability has fulfilled 5 indicators of spatial ability, with a percentage of spatial ability of 95%. Abstrak: Penelitian ini bertujuan untuk mendeskripsikan dan menganalisis kemampuan spasial matematis siswa SMP kelas 8 dalam menyelesaikan soal-soal Pythagoras. Jenis penelitian ini adalah penelitian studi kasus dengan pendekatan kualitatif dan menggunakan desain penelitian kualitatif deskriptif. Penentuan subjek penelitian menggunakan probability sampling lalu didapat 1 siswa dari 33 siswa yang dijadikan sebagai subyek penelitian yaitu Partisipan 1 (P1). Instrumen penelitian berupa tes kemampuan spasial yang sudah tervalidasi serta memenuhi kaidah penulisan instrumen untuk penelitian. Pengumpulan data dalam penelitian ini yaitu observasi, tes, wawancara, dan dokumentasi. Analisis data meliputi reduksi data, penyajian data, dan kesimpulan. Keabsahan data menggunakan triangulasi teknik. Kemampuan spasial matematis P1 telah memenuhi 5 indikator kemampuan spasial, dengan persentase kemampuan spasial 95%.
