Abstract

Tujuan penelitian adalah untuk menganalisis kemampuan literasi matematika siswa kelas X yang didasarkan pada indikator PISA (Level 1-6) dan kemampuannya memecahkan masalah deret aritmatika. Tujuan penelitian dicapai menggunakan metode penelitian deskriptif kualitatif. Sampel terdiri dari 3 siswa yang dipilih secara cluster random sampling dari populasi siswa dalam satu kelas yang berjumlah 21 siswa. Setiap sampel mewakili kelompok siswa dengan kategori kemampuan matematika tinggi (tinggi (S1); sedang (S2), dan; rendah (S3). Data diambil menggunakan instrumen Tes Kemampuan Literasi Matematis dan melalui wawancara. Indikator untuk mengukur kemampuan literasi matematis siswa mengajc pada indikator dalam PISA. Tahapan penelitian yang dilakukan: (1) proses pembelajaran; (2) tes kemampuan literasi matematis; (3) analisis jawaban tes dan wawancara, dan; (4) analisis data dan penarikan kesimpulan. Analisis data dilakukan mengikuti prosedur dari Milles & Hubberman. Kesimpulan yang didapatkan: siswal (S1) mencapai indikator level 1-6; siswa (S2) memenuhi level 1-4, dan; siswa (S3) hanya mencapai indikator Level 1-2

Abstract

This research aims to examine the mindset of students in solving geometry problems from the perspective of spatial ability. This type of research is descriptive qualitative research. The study is conducted to explore and elaborate on the thought processes of students when solving geometry problems in relation to their spatial abilities. The subjects of this research are twelfth-grade students at Perguruan Nasional Senior High School for the 2024/2025 academic year. The research instrument consists of four validated essay questions. Data collection techniques used include tests, interviews, and documentation. The results of the study indicate that subjects with high ability in solving three-dimensional problems have good visualization skills, can formulate problems, and can independently solve complex geometry problems. Students with moderate ability can use diagrams to solve problems, understand basic concepts, and solve questions well, except in the area of pattern recognition. Meanwhile, students with low ability face difficulties in nearly all aspects of testing, particularly in conceptualization, problem-solving, and pattern recognition. Keywords: Geometry problems, mindset, spatial ability
