Meta-Analysis Study: The Effect of Problem Based Learning (PBL) on Students' Mathematical Literacy Skills

Mathematical literacy is an important aspect of the development of students' mathematical abilities.A search was conducted through Google Scholar, Garuda, and Sintaristekbrin portals, resulting in 52 journal articles discussing the impact of implementing the problem-based learning (PBL) model on students' mathematical literacy.This study employed a meta-analysis method to investigate the influence of the PBL model on students' mathematical literacy.Twelve articles that met the inclusion criteria were selected and analyzed using the https://www.meta-mar.complatform, aiming to obtain a significant combined effect size.Based on the interpretation of the combined effect size, it can be concluded that overall, the implementation of the PBL model has a strong influence on students' mathematical literacy.The study also analyzed several study characteristics, including educational level, year of research, sample size, and geographical region of the research.
