The Analysis of Students’ Mathematical Reasoning Ability in Solving Algebra Problems

This study aims to analyze students’ mathematical reasoning ability in solving algebra problems at Universitas PGRI Pontianak. The research employed a descriptive qualitative approach with 25 students enrolled in Algebra courses as participants. Data were collected through algebra problem tests and analyzed using descriptive statistics and thematic interpretation. The findings reveal that 24% of students demonstrate high reasoning ability, 44% moderate reasoning, and 32% low reasoning. The most common difficulties were found in constructing logical arguments, generalizing solutions, and applying algebraic concepts to novel situations. The results indicate that students’ reasoning ability is still limited, particularly in handling non-routine problems, which may affect their algebraic understanding and problem-solving skills. This study highlights the importance of integrating reasoning-based learning strategies in Algebra courses to enhance students’ conceptual and procedural knowledge.
