Meta-analysis: The effect of the discovery learning model on indonesian students’ mathematics reasoning

The ability of mathematical reasoning is one of the important skills for students. The discovery learning model is a suitable learning model to enhance students' mathematical reasoning abilities. The research uses meta-analysis methods through a review of articles in Indonesian national journals. From Google Scholar, Portal Garuda, and Sinta ristekbrin, the author obtained 10 studies that met the inclusion criteria for analysis on the Meta-Mar website to obtain a combined effect size. From the interpretation of this combined effect size, it can be concluded that the overall implementation of the discovery learning model has a moderate effect on students' mathematical reasoning abilities. The characteristics of this research study include educational level, year of research, and sample size. From the statistics, it was found that implementing the discovery learning model to improve students' mathematical reasoning abilities is influenced by educational level, year of research, and sample size.
