Several inconsistent research results regarding the effect of Problem-Based Learning (PBL) in enhancing Mathematical Abilities (MA) of primary school students have been reported widely by some researchers. To summarize, estimate, and evaluate the effect of PBL on MA of primary school students and investigate the study characteristics that provoked the heterogeneous effect size, a systematic review and meta-analysis was employed. Hedge's equation was employed to measure effect size using Comprehensive Meta-Analysis (CMA) software as an analysis tool. The synthesis of 16 relevant primary studies revealed that the overall implementation of PBL had a high positive effect (g = 1,050) significantly compared to conventional learning on MA of primary school students based on a random effect model. Moreover, the characteristics of the sampling technique, publication index, and MA significantly caused the heterogeneity of the effect size of PBL towards students' MA. Thus, these results suggest that primary school mathematics teachers should select PBL as one of the best solutions to enhance students' MA and consider the characteristics of students MA that will be improved. Besides, researchers should select random sampling as a sampling technique to select the sample and the literature indexed by Scopus as references to support the quality of research.

This meta-analysis was conducted to summarize the evidence linking the influence of Contextual Teaching-Learning (CTL) on students' mathematical abilities. The research data was obtained from the ERIC database, sage publishing, Scopus database, semantic scholarships, and google scholarships. The 26 studies that met the inclusion requirements were analyzed to obtain an estimate of effectiveness and examined the extent to which the effect of CTL was moderated by year of study, level of education, sample size, and publication source. The random-effect model is estimated, and data processing uses the Comprehensive Meta-Analysis (CMA) software. The results showed the overall effect size of the study was 0.88 (large effect). The moderator analysis results revealed that the implementation of CTL was moderated by the variables of education level and publication source. On the other hand, the studies' heterogeneity reflects that there are still other moderating variables associated with the effectiveness of CTL. The study's limitations and implications are discussed as the basic idea for the implementation of further research.
