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.

ABSTRACT Background: It is widely known that physical activity has benefits on overall quality of life. Several studies have reported that children with higher physical activity levels had greater whitematter integrity and subcortical structures which critical for learning and memory than children in lower physical activity levels. The purpose of this study was to investigate the effect of physical activity on the academic achievement in primary school students. Subjects and Method: This was meta-analysis and systematic review. The study was conducted by collecting published articles from Google Scholar, PubMed, Springer Link, and Research Gate databases, from 2011-2020. Keywords used “Physical activity” OR “Academic achievement” AND “Cross sectional”. The inclusion criteria were full text, using English or Indonesian language, using cross-sectional study design, and reporting adjusted odds ratio. The study population (P) was primary school students. Intervention (I) was physical activity with comparison (C) sedentary behavior. The study outcome (O) was academic achievement. The collected articles were selected by PRISMA flow chart. The quantitative data were analyzed using Revman 5.3. Results: 6 studies from Saudi Arabia, Malaysia, Chili, United Kingdom, Spanish, and Norway, were met the criteria 6. This study showed that high physical activity improved academic achievement in primary school students (aOR= 1.44; 95% CI= 1.16 to 1.80; p<0.001, with I2= 94%). Conclusion: High physical activity improves academic achievement in primary school students. Keywords: physical activity, academic achievement Correspondence: Fatchurrohmah Ines Prabandari.

Our living environment is increasingly polluted, not only because the amount of resources is increasingly being indiscriminately exploited, there are still many forms of production that pollute the environment, toxic substances which are difficult to decompose into the environment because of not-good human consciousness of some people. The improper collection and classification of daily-life waste is an issue that needs to be addressed. Besides, the situation of indiscriminate garbage disposal and many serious environmental pollution points is formed. Some people even bring domestic waste, dead animal carcasses to rivers and lakes right where they live. Facing the increasing risks of natural environmental pollution, Vietnam needs to promote the education of environmental protection awareness for all people in general and primary school students in particular. Students are the future generation of the country, are the decisive owners for the development of the whole society and are also the people most affected by natural resources and the environment. The article uses survey methods and analyzes data from journals and recent studies. The results show that we need to take action today so that students feel responsible for protecting resources and the environment for a clean and green world.
