Abstract

Numeracy, the ability to apply mathematical concepts to solve real-life problems, is essential for students. This study aims to describe students’ numeracy after learning using the Realistic Mathematics Education (RME) approach in 10th-grade statistics. A qualitative descriptive research method was employed, involving 31 students from class X at Senior High School 9 Yogyakarta. Data collection methods included numeracy tests, interviews based on test results, and observations of lesson implementation. The numeracy test data were analyzed by calculating each student’s score and categorizing them as high, medium, or low. Interview data were analyzed by describing and summarizing the interview results. Observation data on lesson implementation were analyzed by calculating the percentage of lesson implementation. The findings indicate that students’ numeracy skills improved after using the RME approach. The average score on the numeracy test for the statistics material was 84.58, with 30 students classified as having high numeracy skills and one student in the medium category. Based on numeracy indicators, 94.33% of students effectively analyzed information presented in various forms (graphs, tables, charts, diagrams, etc.), 85% used mathematical symbols to solve everyday problems, and 72.33% interpreted these analyses to make predictions and decisions.
