Abstract

In the age of differential learning today, good mathematical literacy is required. Teachers need to understand how to apply effective differential learning and how to monitor students' mathematical literacy during the learning process. This literature review aims to get an idea of how the effectiveness of learning differentiates against the mathematical literacy of students. A literature review was done by collecting various other research articles from 2020 to 2024 using Google Scholar. The author obtained 13 articles using the search keyword "differentiated learning" and 63 articles using the search term "mathematical literature". From the articles obtained through the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) method, which consists of four stages, namely identification, screening, and eligibility, and included, 11 articles were derived that match the purposes of the literature review. Based on the analysis of the review literature, the authors concluded that differentiation approaches could be integrated into learning models such as Problem-Based Learning (PBL), Discovery Learning, and Project Based Learning (PjBL) by considering student learning styles and needs. In differential learning, the use of learning models in the classroom has proved to have a significant impact on students' mathematical literacy.

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.
