Profile of numeration ability in solving trigonometry questions in class x smk 4 semarang examined by initial mathematical ability

Abstract

This study aims to analyze students' mathematical numeracy skills in solving trigonometry problems among 10th-grade vocational high school students, based on their initial mathematical abilities. Students were categorized into three groups based on their initial mathematical ability: (1) high ability, (2) moderate ability, and (3) low ability. This qualitative descriptive study involved 33 students as subjects, with a sample size of 6 students. Data collection utilized test techniques, specifically using summative assessment instruments to assess initial mathematical abilities through trigonometry problems, and numeracy skills through trigonometry-related test questions. Data analysis employed a triangulation technique involving data reduction, data presentation, and conclusion drawing. The findings indicated that in solving trigonometry problems: (1) Students with high mathematical ability were able to fulfill all numeracy skill indicators, evident from their accurate and sequentially correct answers. (2) Students with moderate mathematical ability could not fulfill some numeracy skill indicators, as evidenced by partially correct answers. (3) Students with low mathematical ability could only fulfill some numeracy skills; these students tended to encounter difficulties in problem-solving.In summary, the study demonstrated varying levels of numeracy skills in relation to students' initial mathematical abilities when solving trigonometry problems.
