This paper presents findings from an extensive study conducted in Brazil. The main subjects of the study were Bulgarian children living and studying in Brazilian schools. The main goal was to indicate what kind of problems and obstacles they experience during the school time in Brazil and how the Brazilian government and people support these Bulgarian children. The data was collected by a Bulgarian research team that travelled to the remote regions of Brazil where many Bulgarian citizens live and work. The researchers took interviews with the Bulgarian children and their parents as well as school staff at the schools in Brazil with a high population of Bulgarian children. The analysis revealed many different problems that Bulgarian children and their parents highlighted, such as problems with the language of instructions, misunderstandings of school rules and general problems related to living in the remote areas of Brazil, such as weather and heat-related issues. Although many Bulgarian families reported some problems, they were still determined to continue their life and career in Brazil, and they want to continue to pursue their dreams.

This study investigates school-age children’s arithmetic operations performance while solving larger-size problems which produces interferences in memory. Complex problems can trigger competing responses in working memory, which are irrelevant to a task goal and increase the likelihood of interference from previously learned problems (De Visscher et al., 2018). Interference control in working memory is required to be able to manage and suppress irrelevant information while performing cognitive tasks such as arithmetic problem-solving (Unsworth, 2010). The present study explores potential cognitive processes while performing arithmetic tasks and emphasizes the important role of interference control for better performance in such tasks. This study applied a mixed-effect model experimental design. Forty-four primary school children were involved in the study. The results showed that children’s performance in terms of correct responses was similar for both small-size and large-size problems. However, their response speed was significantly lower in larger-size problems, which created more interference in working memory.

According to the systems perspective, the influence of various systems (e.g., family, school, community) on children's behavior at school is highly acknowledged. It is therefore accepted that problem behavior in the classroom originates from social interactions, providing a conceptual framework where problems are seen as indicative of dysfunction within the school system, thus removing blame from the individual child, the teacher, or the parents. Addressing the importance of interactions among students, teachers, and parents in this system, the present study aimed to identify and compare the types of behaviors that Greek primary and secondary teachers and parents view as problematic in the classroom. A sample of 378 teachers and 69 parents were asked to identify which behaviors were considered troublesome. Exploratory factor analysis revealed five categories of behaviors perceived as problematic by parents and teachers: Externalizing behaviors, School Difficulties, Internalizing behaviors, Attention seeking behaviors, and Hyperactivity/attention difficulties. Both teachers and parents considered externalizing behaviors to be more troublesome than other types of behavior. Teachers tend to worry less than parents about all types of children’s behaviors, except for school difficulties. The findings highlight the importance of considering diverse perspectives within the school system when designing interventions to address the specific needs of school communities while also promoting collaboration among all members of the school system.
