Abstract
Membuat model matematis merupakan faktor penting dalam menyelesaikan masalah. Penelitian ini bertujuan untuk memberikan deskripsi rinci mengenai kesulitan siswa dalam membuat model matematis dalam penyelesaian masalah kontekstual yang berkaitan dengan bilangan. Penelitian ini bersifat kualitatif dengan desain fenomenologi hermeneutik. Subjek penelitian ini adalah 33 siswa kelas delapan dari tiga sekolah di Bandung. Teknik pengumpulan data yang digunakan adalah tes dan wawancara. Sebelum digunakan, instrumen ini divalidasi oleh para ahli, terutama pada konten, konstruk, dan penampilan. Pengecekan keabsahan temuan penelitian telah dilakukan diantaranya melalui prinsip credibility, transferability, dependability, dan confirmability. Terdapat empat kesimpulan dalam penelitian ini. Pertama, kesulitan yang dihadapi oleh siswa dalam membuat model matematis adalah sulit memahami situasi/matematika secara konseptual, sulit mengidentifikasi variabel yang relevan, membuat model matematis tanpa melibatkan konteks, sulit membuat visualisasi yang relevan, sulit menggunakan rumus yang memadai, sulit menjawab pertanyaan dengan bantuan hasil matematika, dan sulit menyesuaikan hasil (sementara) dengan situasi sebenarnya. Faktor utama yang memengaruhi kesulitan siswa dalam membuat model matematis adalah kurangnya pemahaman konsep matematis siswa, ketidakmampuan siswa dalam mengaplikasikan konsep, dan keterbatasan pengalaman praktis dalam pemodelan matematis. Keterbatasan pengalaman praktis dalam pemodelan matematis ini membuat kemampuan model ikonik lebih rendah daripada kemampuan model simbolik. Creating mathematical models is a crucial factor in solving problems. This research aims to provide a detailed description of students' difficulties in creating mathematical models in solving contextual problems related to ratio and linear equations. The study adopts a qualitative approach with a phenomenological hermeneutic design. The research subjects consist of 33 eighth-grade students from three schools in Bandung. Data collection techniques include tests and interviews. Before usage, the instruments were validated by experts, particularly in terms of content, construct, and appearance. Data analysis involves identifying meanings, determining credibility, interpreting data, identifying themes, and compiling the final report. The research draws four conclusions. First, students' difficulties in creating mathematical models include a failure to understand the situation/mathematics conceptually, an inability to identify relevant variables, creating mathematical models without involving context, failing to produce relevant visualizations, failing to use adequate formulas, and failing to answer questions with the assistance of mathematical results. Furthermore, they fail to adjust (temporarily) their results to the actual situation. The main factors influencing students' difficulties in creating mathematical models are their lack of understanding of mathematical concepts, their inability to apply these concepts, and their limited practical experience in mathematical modeling. Their limited practical experience in mathematical modeling made the iconic model ability lower than the symbolic model ability.
