Analysis of Class X MAN Surabaya Students' Mistakes in Solving Function Questions Quadratics Based on Learning Styles and Newman Procedures

Abstract

This qualitative descriptive research aims to examine the errors students make when solving quadratic function problems, focusing on their learning styles and the Newman procedure. The study targeted grade X-H students of MAN Surabaya, selected through purposive sampling. The research employed learning style questionnaires, math tests, and interview guidelines as instruments. The findings revealed five stages of errors in solving the test based on Newman's procedural error analysis, with the following contributing factors: (a) Reading errors: Students often rush and are careless when reading questions, a tendency seen in those with auditory and kinesthetics learning styles; (b) Misunderstanding: Students fail to accurately identify what is given and what is asked due to prior mistakes, commonly observed in auditory and kinesthetics learners; (c) Transformation errors: Students struggle to understand the material and misuse formulas, frequently occurring among kinesthetics learners; (d) Process skill errors: Mistakes in applying steps to use formulas correctly, often stemming from earlier errors, observed across auditory, visual, and kinesthetics learners; and (e) Final answer errors: Mistakes in writing results, influenced by prior errors, also affecting auditory, visual, and kinesthetics learners.
