Abstract

Mathematical literacy skills are one of the essential aspects that students need to master because, through this ability, they can solve problems in everyday life. Providing Programme for International Student Assessment (PISA) questions is one of the teachers' efforts to develop students' mathematical literacy skills. This study aims to describe the observed mathematical literacy ability of students learning independence and analyze the difficulties experienced by students in solving PISA problems. The study subjects consisted of 20 students of SMPN 02 Siak Hulu. The research method used is descriptive. The research instrument is PISA test questions oriented to quantity content, learning independence questionnaires, and interviewguidelines. The data obtained is analyzed by reducing, presenting, and drawing conclusions. The result of this study is that students doing PISA questions are still experiencing difficulties. This difficulty occurs because students are unfamiliar with PISA model questions. They do not understand the meaning of the problem, do not understand the material in the problem, are confused about determining mathematical concepts, and cannot apply problem-solving strategies.

Abstract

This research is motivated by the low both Mathematical Problem Solving Ability (KPMM) and Mathematical Disposition (DM) in solving problems of grade VII MTs students. This study aims to see an increase in KPMM and DM MTs students in Kuantan Singingi Regency. The form of research was quasi-experimental with pretest-posttest control group design. The population of the study was MTs students in Kuantan Singingi District with the sample being Grade VII students from 3 MTs in Kuansing. Data collection instruments in this study were KPMM tests and DM questionnaires. Data were analyzed using t-test, Mann- Whitney U test, one-way Anova. The results obtained were an increase in KPMM for students who treated with Think Talk Write (TTW) strategies in cooperative learning. They were higher than students who obtained learning with a scientific approach (g_TTW = 0.75> 0.61 = g_PS). So it appears that the increase in KPMM and DM students who get the TTW Strategy in Cooperative Learning is higher than students who get learning with a scientific approach.

Abstract

Penelitian ini bertujuan untuk memberikan gambaran terkait kemampuan penalaran matematis siswa dalam menyelesaikan soal pada materi fungsi eksponensial. Penelitian ini. menggunakan penelitian deskriptif kualitatif. Penelitian ini dilaksanakan di SMA Negeri 4 Pekanbaru dengan subjek siswa kelas X-5 yang berjumlah 19 siswa. Instrumen yang digunakan berupa soal tes kemampuan penalaran matematis sebanyak 4 butir soal dan pedoman wawancara. Hasil penelitian menunjukkan bahwa kemampuan penalaran matematis siswa pada materi fungsi eksponensial tergolong dalam kategori rendah. Siswa mengalami kesulitan dalam memahami materi fungsi eksponensial. Rendahnya kemampuan penalaran matematis subjek terlihat pada  ketidakmampuannya dalam indikator: (1) melakukan manipulasi matematika, (2) menarik kesimpulan berdasarkan data yang teramati (generalisasi), dan (3) menganalisis situasi matematis menggunakan pola dan hubungan. Hal ini disebabkan oleh kurangnya latihan yang dilakukan siswa, terutama ketika soal yang diberikan memiliki bentuk yang berbeda dari contoh yang diajarkan. Selain itu, ditemukan adanya miskonsepsi, di mana beberapa siswa menganggap bahwa persamaan fungsi eksponensial sama dengan persamaan fungsi linear.

Abstract

This research investigates student errors in solving contextual problems involving Systems of Linear Equations in Three Variables (SPLTV) using Newman’s Error Analysis framework. The theory categorizes errors into five cognitive stages: reading, comprehension, transformation, process skills, and encoding. A qualitative descriptive method was applied, involving three 10th-grade vocational school students from different majors in Kampar Regency, selected based on varying ability levels. Data were collected through contextual written tests and interviews. Findings reveal that low-ability students made errors across all stages, medium-ability students primarily struggled with process skills and encoding, while high-ability students demonstrated minimal errors and systematic problem-solving. The highest error rates occurred in the reading and comprehension stages (33% each), followed by transformation, process skills, and encoding (22% each). These results highlight the crucial role of contextual understanding and mathematical modeling in SPLTV. The study recommends differentiated instruction and the integration of contextual problems to reduce errors and enhance students' mathematical thinking.   Penelitian ini mengkaji kesalahan siswa dalam menyelesaikan soal kontekstual Sistem Persamaan Linear Tiga Variabel (SPLTV) dengan menggunakan kerangka Analisis Kesalahan Newman. Teori ini mengelompokkan kesalahan ke dalam lima tahapan kognitif, yaitu membaca, memahami, transformasi, keterampilan proses, dan penulisan jawaban. Metode deskriptif kualitatif diterapkan dengan melibatkan tiga siswa kelas X dari jurusan berbeda di salah satu SMK di Kabupaten Kampar, yang dipilih berdasarkan tingkat kemampuan yang bervariasi. Pengumpulan data dilakukan melalui tes tertulis berbentuk soal kontekstual dan wawancara. Hasil penelitian menunjukkan bahwa siswa berkemampuan rendah melakukan kesalahan pada seluruh tahapan, siswa berkemampuan sedang terutama mengalami kesalahan pada tahap keterampilan proses dan penulisan jawaban, sedangkan siswa berkemampuan tinggi menunjukkan kesalahan minimal dan mampu menyelesaikan soal secara sistematis. Persentase kesalahan tertinggi terjadi pada tahap membaca dan memahami (masing-masing 33%), diikuti oleh tahap transformasi, keterampilan proses, dan penulisan jawaban (masing-masing 22%). Temuan ini menegaskan pentingnya pemahaman konteks dan kemampuan pemodelan matematis dalam menyelesaikan SPLTV. Penelitian ini merekomendasikan penerapan pembelajaran diferensiatif serta integrasi soal kontekstual untuk mengurangi kesalahan dan meningkatkan kemampuan berpikir matematis siswa
