Problem solving ability is one of the skills that need to be developed in students. Through searching the Google Scholar database, 75 journal articles were found that discussed mathematical problem-solving abilities. This study uses a meta-analysis design to determine the effect of applying several learning models on mathematical problem-solving abilities. Of all the articles obtained, there were 12 articles that met the predetermined criteria to be analyzed using the help of the online meta-analysis calculator application which can be accessed on the website https://meta-mar.shinyapps.io/meta-analysis-calculator/ so that an effect was obtained. combined sizes. Based on the interpretation of the combined effect size, it can be concluded that overall, the application of learning models from each study including: PBL, PjBL, Generative, and Geogebra-assisted has a strong influence on mathematical problem-solving abilities. There are also characteristics analyzed in this study including the year of research, educational level, and learning model. Statistically, it was found that the application of learning models to improve mathematical problem-solving abilities was influenced by the level of education and the learning model used.
