ANALYSIS OF STUDENTS’ MATHEMATICAL PROBLEM-SOLVING ABILITY ON THE CONCEPT OF LIMITS REVIEWED FROM THEIR MATHEMATICAL THINKING STYLES AT MAS PP AMIRUDDINIYAH PURBA SARI, BANDAR TINGGA VILLAGE, BILAH HULU SUBDISTRICT, LABUHANBATU REGENCY

Abstrak

This study aims to explore how students understand and solve problem-solving tasks on the topic of function limits, as well as how their thinking styles influence their performance. The research used a qualitative approach supported by quantitative data. Data were collected through tests, thinking-style questionnaires, and interviews with 30 eleventh-grade students. The results show that students’ abilities vary: some can solve the problems well, some perform moderately but still make mistakes, and some struggle to understand the steps involved. Most students fall into the moderate category. Students with an analytic thinking style tend to be more organized and able to follow problem-solving steps clearly, while those with less systematic thinking styles often stop midway or feel confused about which step to take next. These findings indicate that students’ thinking styles affect how they solve problems. Therefore, teachers need to adjust their teaching strategies to match students’ thinking characteristics so that they can better understand the concepts and improve their problem-solving skills.
