Abstract

This study aims to describe students’ numeracy skills in solving contextual problems on algebraic expressions based on their logical-mathematical intelligence. This research employed a descriptive qualitative method with subjects consisting of seventh-grade students at SMP Negeri 2 Mataram in the 2024/2025 academic year. Data were collected through a logical-mathematical intelligence test, a numeracy test consisting of two contextual essay questions, and in-depth interviews. The results show that students with high logical-mathematical intelligence demonstrate high numeracy skills, as indicated by their ability to use mathematical symbols and numbers accurately, analyze data in various forms, and draw logical conclusions. Students with moderate logical-mathematical intelligence have moderate numeracy skills—they can identify numerical information but still make calculation and interpretation errors. Meanwhile, students with low logical-mathematical intelligence show low numeracy skills, characterized by difficulties in understanding data, performing arithmetic operations, and interpreting results. These findings indicate a strong relationship between students’ logical-mathematical intelligence levels and their numeracy abilities in solving contextual problems involving algebraic expressions.

Abstract

This study aimed to describe students Self Regulated Learning abilities and mathematical problem-solving abilities, as well as to determine whether there was a significant influence of self regulated learning on the mathematical problem solving abilities of Grade XI Science students at SMA NW Mataram in the 2025/2026 academic year. This study employed a ex pos facto with a quantitive approach. The population and sample consisted of all 31 students of Grade XI Science at SMA NW Mataram. The research instruments included a self regulated learning questionnaire and a mathematical problem solving test. The test material in this study consists of sequences and series. The data were analyzed using simple linear regression analysis. The results showed that: (1) the students self regulated learning ability was in the moderate category, with a percentage of 64.5%; (2) the students' mathematical problem-solving ability was also in the moderate category, with a percentage of 83.88%; and (3) there was a significant influence of self regulated learning on students mathematical problem solving ability. This finding was supported by the regression equation Y = 2.777 + 0.221X and the results of the F-test, which indicated that Fcalculated = 30.786 was greater than Ftable = 4.18. Furthermore, the coefficient of determination (R²) was 0.515, indicating that self regulated learning contributed 51.5% to students mathematical problem solving ability, while the remaining 48.5% was influenced by other factors.
