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.

The objective of this study was to review the existing international literature on research and programs for the reduction of disruptive behavior in primary school students. For this purpose, according to PRISMA-ScR, a mixed systematic review was performed in six databases in order to obtain wide and extensive information related to the subject under study. The studies obtained were analyzed through a table which emphasized the data related to: Author(s), year, educational stage, location, objectives, instruments, and results. As for the selection of studies, the UNESCO Thesaurus and the ERIC Thesaurus terminology was used. In addition to specifying the search for studies performed between 2004 and 2020 (both inclusive), articles written in Spanish and English were selected. Furthermore, in a final phase among the articles analyzed, those that were not or did not contain intervention programs were discarded. Therefore, a total of thirty-five articles out of more than twenty thousand were analyzed in depth. The results showed that a majority of programs were implemented in the primary education stage, as well as a predominance of the use of instruments, such as questionnaires and observation charts. In addition, it is important to underline that 77.14% of the programs analyzed were effective, hence, they met the proposed objectives. In summary, although the number of intervention programs for the reduction of disruptive behavior that can be found in the international scientific literature is growing, there is still a long way to go in order to create a large network that can serve as a foundation for interventions in primary education students.

Abstract Background: Though undernutrition affects academic performance significant numbers of Ethiopian school children have undernutrition. To avert nutritional problems the government in collaboration with the world food program has implemented a school feeding program. However, data on the nutritional status of primary school students were scarce in the country. Therefore, this study aimed to compare the nutritional status of primary school students enrolled in schools with school feeding programs and in schools without school feeding programs and to identify associated factors in Meket Woreda.Methods: A school-based comparative cross-sectional study was conducted among 1,091 students, from April 1-27/2015. The study participants were selected using a multi-stage stratified sampling method. A structured questionnaire was used to collect data. Data entry and analysis were done using SPSS version 20 software. Descriptive statistics and logistic regression analyses were done. Anthropometric data were analyzed using Anthro-plus software.Results: The prevalence of thinness was 37.5% among students in non school feeding program schools compared with 27.8 % among students in School feeding program schools. Though it wasn’t significant after adjusting for the potential confounders, the prevalence of stunting among students who took meals at school was higher (58.5%) compared with students who did not consume meals at school (48.3%). Students who did not take meal at school [AOR=2.6, 95% CI: (1.8, 3.8)], having uneducated mother [AOR=5.3, 95% CI: (2.2, 12.6)], being a male [AOR=1.9, 95% CI: (1.4, 2.5)], and taking meal once daily [AOR=2.7, 95% CI: (1.6, 3.9)] were positively associated with thinness. Conclusion: The prevalence of thinness was higher among students in schools did not implement school feeding programs compared to their counterparts. Thus, school meal program should be scaling up into schools in food insecure areas.
