Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan literasi matematika siswa dalam menafsirkan infografik statistik yang disajikan di media sosial. Penelitian menggunakan pendekatan kualitatif dengan jenis penelitian deskriptif dan dilaksanakan pada siswa kelas X MA Madani Alauddin Makassar. Subjek penelitian terdiri atas tiga siswa yang dipilih melalui teknik purpose sampling untuk mewakili kategori kemampuan matematika tinggi, sedang, dan rendah. Pengumpulan data dilakukan melalui observasi dan pemberian soal literasi matematika berbasis infografik statistik. Analisis data mengacu pada model Miles dan Huberman yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa kemampuan literasi matematika siswa dalam menafsirkan infografik statistik berada pada kategori cukup hingga perlu bimbingan. Siswa umumnya mampu mengidentifikasi informasi dasar, membaca tabel dan diagram, serta menentukan data yang dominan pada infografik. Namun, siswa masih mengalami kesulitan dalam melakukan perhitungan yang tepat, menganalisis hubungan antar data, serta menyusun argumentasi yang didukung oleh bukti matematis. Temuan ini menunjukkan bahwa kemampuan interpretasi dan penalaran matematis siswa masih perlu ditingkatkan melalui pembelajaran yang lebih kontekstual dan berbasis data. Oleh karena itu, penggunaan infografik statistik dalam pembelajaran dapat menjadi salah satu alternatif untuk meningkatkan kemampuan literasi matematika siswa di era digital.

Abstract

This study aims to optimize the use of the Kodular application as a competency testing instrument for students of the Mathematics Education Study Program at UIN Alauddin Makassar. This application is integrated with Google Form as a question platform and is equipped with a login token feature, exam timer, and automatic detection system. The method used is Research and Development (R&D) with the ADDIE development model implemented. The results showed that 97.14% of students stated the exam system was easy to use, 93.5% could understand the exam display clearly, 92.14% successfully installed the application on their respective devices, and 93.57% felt they could work on questions more focused, controlled, and minimizing cheating. The average student competency test score reached 69.14/100 with a median of 68 and a range of 64–76. Thus, Kodular is proven to be optimized as an innovative, transparent, and integrity-based competency testing medium in mathematics education at higher education institutions.

Abstract

Mathematical literacy is an essential skill required for students to solve problems in real-life contexts. However, students still experience difficulties in solving mathematical literacy problems, particularly those based on real-world data. This study aimed to analyze students' errors in solving mathematical literacy problems based on regional public data using Newman’s Procedure. This research employed a descriptive qualitative approach and was conducted at SMP Negeri 2 Sungguminasa. A total of 24 eighth-grade students participated in the test, from which three students representing high, medium, and low ability categories were selected through purposive sampling. Data were collected through mathematical literacy tests developed using official statistical data from South Sulawesi Province, semi-structured interviews, and documentation. The results showed that each ability category exhibited different types of errors. High-ability students made comprehension and encoding errors. Medium-ability students made comprehension, transformation, process skills, and encoding errors. Meanwhile, low-ability students experienced errors at all stages of Newman’s Procedure. These errors were influenced by students’ limited understanding of problem information, unfamiliarity with mathematical literacy problems based on regional public data, and difficulties in interpreting calculation results within the given context.
