Literasi Matematika Siswa dalam Menyelesaikan Soal PISA Ditinjau dari Resiliensi Matematis

Students’ Mathematical Literacy in Solving PISA Questions Viewed from Mathematical Resilience

Literasi matematika merupakan kemampuan seseorang dalam merumuskan, menerapkan, dan menafsirkan matematika di berbagai konteks dunia nyata. Penelitian ini bertujuan untuk mendeskripsikan literasi matematika siswa dengan resiliensi matematis tinggi, sedang, dan rendah dalam menyelesaikan soal PISA. Penelitian ini merupakan penelitian deskriptif dengan pendekatan kualitatif. Subjek penelitian terdiri dari masing-masing 1 subjek resiliensi matematis tinggi, sedang, dan rendah. Teknik pengumpulan data menggunakan metode angket, tes, dan wawancara. Hasil penelitian menunjukkan pada proses formulating situations mathematically ketiga subjek mengidentifikasi aspek matematis dalam permasalahan, menggunakan simbol matematika, membuat model matematika dari masalah, dan menyebutkan konsep matematika yang digunakan. Subjek resiliensi matematis rendah menyebutkan aspek matematis dalam permasalahan secara tidak lengkap dan membuat model matematika yang belum sesuai. Subjek resiliensi matematis tinggi dan sedang mengenali struktur matematis dalam masalah dan menyebutkan batasan serta asumsi sesuai dengan model matematika. Pada proses employing mathematical concepts, facts, procedures and reasoning, ketiga subjek menerapkan strategi untuk menemukan solusi matematis dari suatu masalah. Ketiga subjek menyebutkan simbol, aturan, serta prosedur matematika yang digunakan. Subjek resiliensi matematis sedang dan rendah melakukan prosedur matematika yang belum tepat. Subjek resiliensi matematis tinggi merefleksikan argumen matematis dan menjelaskan serta membenarkan hasil matematis. Pada proses interpreting, applying and evaluating mathematical outcomes, siswa resiliensi matematis tinggi dan sedang menarik kesimpulan sesuai konteks permasalahan serta menjelaskan alasan hasil yang didapatkan masuk akal atau tidak berdasarkan konteks permasalahan.

        Mathematical literacy is a person's ability to formulate, apply, and interpret mathematics in various real-world contexts. This study aims to describe the mathematical literacy of students with high, medium, and low mathematical resilience in solving PISA questions. This research is a descriptive research with a qualitative approach. The research subjects consisted of 1 subject each of high, medium, and low mathematical resilience. Data collection techniques used questionnaires, tests, and interviews. The results showed that in the process of formulating situations mathematically, the three subjects identified mathematical aspects in the problem, used mathematical symbols, made mathematical models of the problem, and mentioned mathematical concepts used. Low mathematical resilience subject mentioned the mathematical aspects in the problem incompletely and made mathematical models that were not appropriate. High and medium mathematical resilience subjects recognized the mathematical structure in the problem and mentioned limitations and assumptions in accordance with mathematical model. In the process of employing mathematical concepts, facts, procedures and reasoning, the three subjects applied strategies to find mathematical solutions to problems. All three subjects mentioned the mathematical symbols, rules and procedures used. Moderate and low mathematical resilience subjects performed mathematical procedures that were not yet correct. High mathematical resilience subjects reflected on mathematical arguments and explained and justified mathematical results. In the process of interpreting, applying and evaluating mathematical outcomes, high and medium mathematical resilience students drew conclusions according to the context of the problem and explained why the results obtained made sense or not based on the context of the problem.
