Abstract

Numeracy skills are essential competencies that enable students to understand, process, and interpret mathematical information in various real-life contexts. However, students’ numeracy skills still need improvement, particularly in statistics learning. This study aimed to determine the effect of implementing the Problem-Based Learning (PBL) model through local culture-based Student Worksheets (LKPD) on the numeracy skills of tenth-grade students at SMAN 3 Mataram. This study employed a quasi-experimental method using a posttest-only control group design. The sample consisted of 78 students divided into an experimental class and a control class. Numeracy data were collected using a test instrument that had been validated by experts. The findings showed that students who learned through PBL with local culture-based LKPD achieved higher numeracy skills than those who received direct instruction. The results of the independent sample t-test indicated a significant difference between the two groups, with a very high level of instructional effect. These findings suggest that the implementation of PBL through local culture-based LKPD is effective in supporting the improvement of students’ numeracy skills in statistics learning.

Abstract

Mathematics is a core subject in high school that plays an important role in developing students' logical and analytical thinking skills. However, abstract concepts such as building space are often challenges in themselves that have an impact on students' low learning outcomes. This study aims to identify, classify, and synthesize the results of previous research on the effectiveness of the use of teaching aids in improving mathematics learning outcomes in building materials at the high school level. The method used is the Systematic Literature Review (SLR), by examining 12 scientific articles published between 2015 and 2025, which meet certain inclusion criteria. The results of the study show that the use of teaching aids, both physical and digital, consistently has a positive impact on concept understanding, learning motivation, and student evaluation results. Teaching aids also make it easier for teachers to explain abstract concepts to be more concrete and easy to understand. Based on these findings, this study recommends the integration of teaching aids into the mathematics learning process, especially in building space materials, in order to improve the quality and learning outcomes of students at the high school level.
