In this study, it was aimed to reveal the effect of using technology in the primary mathematics education on the students’ academic achievement. In accordance with this purpose,  the current study is to determine the overall effect size by bringing together the experimental studies conducted on the effect of using technology in primary school mathematics teaching between 2013 and 2019 on students’ academic achievement. The meta-analysis method was used because it was aimed to calculate the effect sizes of studies examining the effect of technology-based applications used in mathematics education on academic achievement. As a result of the analysis, the effect size of the analyzed studies was found to be 0.483. Also, a significant difference was found between the effect sizes in relation to grade level, technology-based applications, the duration of the studies, the type of the study, and whether the study was conducted nationally or internationally. It was concluded that the technologies used in primary school mathematics teaching have a small positive effect on students' mathematics achievement.

Bu araştırmada ilkokul seviyesinde öğrenim gören geçici koruma altındaki Suriyeli öğrencilerin okullara uyum sürecinin ortaya konulması amaçlanmıştır. İç içe geçmiş tek durum deseniyle tasarlanan bu araştırmada çalışma grubunu 101 Türk, 16 Suriyeli öğrenci ve 9 öğretmen oluşturmaktadır. Öğrenciler arasındaki ilişkileri ölçmek amacıyla veri toplama aracı olarak sosyometri kullanılmıştır. Ayrıca, araştırmaya katılan öğrencilerin sınıflarında görev yapan öğretmenler ile yarı yapılandırılmış görüşmeler gerçekleştirilmiştir. Sosyometri aracından elde edilen verilerden sosyagramlar hazırlanarak sunulmuştur. Yarı yapılandırılmış görüşmelerden elde edilen veriler de içerik analiziyle incelenerek, sunulmuştur. Araştırma sonucunda ilkokul seviyesindeki Suriyeli öğrencilerin oyun oynamak için birbirlerini tercih ettikleri ve velilerden, öğretmenlerden kaynaklı sorunların devam ettiği tespit edilmiştir. Buna ilave olarak öğretmenlerden bazıları sınıflarında uyum sorunu olduğunu düşünmese de sosyogramlarda bunun aksine uyum sorunu olduğu tespit edilmiştir.

The aim of this study is to determine the relationship between 3rd and 4th-grade primary school students’ critical thinking dispositions and decision-making skills. The participants in this study consist of 3rd and 4th grade students studying in a primary school in Istanbul, Turkey, and a total of 749 students participated. The correlational design, one of the quantitative research designs, was used in the study. The Critical Thinking Disposition Scale for Primary School Students and the Decision-Making Skills Scale for Primary School Students were used as data collection tools. An independent sample t-test was conducted to examine the scales according to variables such as gender and grade level. One-Way Analysis of Variance (ANOVA) was applied to examine the scale scores according to the educational status of the parents. Finally, Simple Linear Regression Analysis was performed to examine the relationship between the scales. The results showed that the critical thinking disposition level of primary school students was higher than the mean score, and their decision-making skills were average. Also, it was found that primary school students’ critical thinking dispositions predicted their decision-making skills.
