Parental involvement is an important factor in students’ achievement, and numerous studies have shown that it increases students’ success. As research on father’s involvement has become one of the current topics in education today, there is a need to separate the effect exercised by fathers from the overall family one. The aim of this study is to synthesize various studies which have focused on different aspects of fathers’ involvement; therefore, a meta-analysis would be an ideal method to create a synthesis of these perspectives and provide one general measure of fathers’ involvement effect. Nine studies have been included in the meta-analysis, where fathers’ involvement has been operationalized through father’s involvement in: education of children at school and at home, psychosocial well-being of children, modelling of behavior and leisure activities. The results show that the total measure of effect size differs from zero after applying the fixed model (z=13.510, p=0.000) and the random effect model (z=4.588, p=0.000), that is, there is a statistically significant positive correlation between the involvement of fathers and the academic success of their children. The value of the heterogeneity test (Q=66.560, df=8, p=.000, I2=87.981) indicates that the overall effect can be viewed according to the assumptions of the random effects model. The conducted meta-analysis has confirmed the assumption that fathers’ involvement is positively related to children’s academic performance.

Academic media multitasking specifically refers to the phenomenon where students or academics divide their attention between learning-related activities, such as studying or reading scholarly material, and non-learning activities like texting friends, checking social media, or browsing unrelated websites. Studies confirm a negative correlation between media multitasking and academic achievement, with some reporting small to moderate effects or no correlation at all. This topic is particularly important today due to the pervasive use of media among younger generations and its impact on attention, focus, academic performance, and cognitive load. This meta-analysis aimed to quantitatively integrate individual correlational studies and draw general conclusions about the relationship between academic media multitasking and academic achievement. The sample comprised studies published in English scientific journals from 2010 to the present, with methodological characteristics matching the context of this analysis. A total of 11 studies were included in the final analysis. Correlation coefficients were used as a measure of effect size, with both fixed and random effects models applied to calculate the overall measure of effect size. The quality of the included studies was assessed, and potential publication bias was examined using a symmetry graph and Trim and Fill analysis. The results confirmed a low-intensity negative correlation between digital multitasking and academic achievement with a weighted average correlation coefficient of r=−0.252 (fixed effects model) and r=−0.246 (random effects model) and high heterogeneity (I² = 93.98%) among the studies, suggesting variability in the findings. The present meta-analysis also revealed high heterogeneity among the studies, suggesting variability in the findings. This heterogeneity opens avenues for exploring potential mediating relationships or covariates that impact why students engage in digital multitasking.

In this paper has been given reconsideration of the role of the family in children's cognitive development with the focus on different factors which give the frame to this process. There have been given reconsideration of theoretical frames which are explaining how the economic status of the family, parent's involvement, the quality of the relation parent-child and socio-emotional support influence the children's cognitive development. Based on the Theory of Economic Investments there have been given reconsideration of how parents use the recourse like time, education and activities in the free time for improving of cognitive abilities of their children. Research have shown that children from the families with higher economic status and higher parent's educational level reach better cognitive results, but also that the stress caused by economic problems can have negative influence on children's development. The Attachment Theory stresses the importance of emotional stability an security in early life phases for development of cognitive functions. Also, the importance of positive parenting which is characterized by warmth, support and non violent methods of discipline has the huge influence on the development of intellectual and social abilities of children. It is concluded that family environment, like the activities that parents are performing with their children play the main role in forming of stimulative environment for cognitive development, so the continuous support and parent's involvement are from the essential importance for children's early development.
