How Do Students Mathematize in Solving Algebra Problems? A Case Study at SMPN 2 Balusu

Abstract

Algebra is an important subject in mathematics learning because it serves as a foundation for understanding higher concepts and as a tool for modeling various problems. However, many students still experience difficulties in connecting contextual problems into mathematical models. This study aims to describe the process of students' mathematization in solving algebraic problems, including the stages of understanding the problem, formulating a model, problem-solving, and reflecting. The type of research used to achieve this goal is qualitative. The research subjects consisted of three students at SMPN 2 Balusu who were selected based on their answer patterns. The results showed that each student had a different approach to solving algebraic problems. Some students were able to work sequentially, starting from understanding the problem, creating a model, and rechecking the results. There were also students who actually understood the core of the problem, but still made mistakes when creating the model, resulting in inconsistent answers. Meanwhile, some chose shortcuts by guessing numbers to get the answer.
