Abstract
Numerasi merupakan kemampuan untuk berpikir secara matematis dalam merumuskan, menggunakan, serta menerapkan konsep dasar dan proses matematika ke dalam kehidupan sehari-hari. Aljabar merupakan salah satu materi yang membutuhkan numerasi yang baik. Ketika menyelesaikan soal-soal aljabar, siswa masih mengalami berbagai kesalahan. Kesalahan siswa diidentifikasi berdasarkan Teori Newman yaitu, reading error, comprehension error, transformation error, process skill error, dan encoding error. Salah satu faktor yang dapat mempengaruhi numerasi seseorang ialah Adversity Quotient (AQ). Penelitian ini bertujuan untuk mendeskripsikan numerasi dan kesalahan siswa dalam menyelesaikan soal-soal aljabar ditinjau dari AQ yang dikategorikan ke dalam tiga tipe AQ, yaitu quitter, camper, dan climber. Penelitian ini menggunakan metode studi kasus dengan pendekatan kualitatif. Subjek pada penelitian ini yaitu 33 siswa kelas VIII di salah satu SMP di Kota Bandung. Instrumen yang digunakan meliputi tes numerasi berbasis soal aljabar, kuesioner AQ, dan wawancara mendalam. Hasil penelitian menunjukkan bahwa siswa dengan AQ tipe climber memiliki capaian numerasi tertinggi dan frekuensi kesalahan terendah, sedangkan siswa dengan AQ tipe quitter menunjukkan capaian numerasi terendah dan kesalahan terbanyak pada hampir seluruh tahapan Newman. Siswa dengan AQ tipe camper berada di antara kedua kelompok tersebut, baik dari segi capaian maupun jenis kesalahan. Pola kesalahan yang paling dominan terjadi pada tahap transformation error dan process skill error, terutama pada siswa dengan AQ rendah. Numeracy is the ability to think mathematically in formulating, using, and applying basic concepts and mathematical processes in everyday life. Algebra is one of the subjects that requires strong numeracy skills. While working on algebra problems, students still commit various errors. Students’ errors are identified based on Newman’s Theory, namely reading error, comprehension error, transformation error, process skill error, and encoding error. One factor that may influence an individual's numeracy is Adversity Quotient (AQ. This study aims to describe students’ numeracy and errors in solving algebra is problems based on of AQ, which is categorized into three types: quitter, camper, and climber). This research employs a case study method with a qualitative approach. The subjects of this study were 33 eighth-grade students at a junior high school in Bandung. The instruments used included an algebra-based numeracy test, an AQ questionnaire, and in-depth interviews. The results indicate that students with the climber-type AQ achieved the highest numeracy performance and the lowest frequency of errors, while students with the quitter-type AQ demonstrated the lowest numeracy performance and the most errors across nearly all Newman stages. Students with the camper-type AQ were positioned between these two groups in terms of both achievement and types of errors. The most dominant error patterns occurred at the transformation error and process skill error stages, particularly among students with low AQ.
