Executive functions (EF) and self-regulation (SR) are fundamental for children's learning, school functioning and academic achievement. EF/SR fail to develop to its full potential if contextual stimulation is not adequately presented. This is evident in the training programmes directly and exclusively targeting EF/SR stimulation, which lack durable and transferable effects. Therefore, recent research has shifted the attention towards malleable environmental factors; more specifically, to the role of school and classroom environment as an important developmental context for promoting children's EF/SR skills and, in turn, their cognition and behaviour. Numerous observational studies have shown a correlation between the quality of teacher-student relationship (TSR) at the dyadic level or teacher-student interaction (TSI) at the classroom level and children's EF/SR skills. To explore the direction of this association, the objective of this systematic literature review was to examine the causal effect of experiments and interventions that aim to improve children's EF/SR by manipulating the TSI. Overall, the results from 18 included studies indicated that children in treatment groups show higher gains, albeit small-sized, in EF/SR performance compared to controls. Furthermore, TSI manipulation seemed to affect children's SR skills more strongly than children's EF skills. More importantly, the findings revealed the largest effects of these manipulations in children considered vulnerable or disadvantaged, suggesting that the cognitive deficits can be minimised if these children are supported appropriately. Given high study heterogeneity, this review highlights the need for more research (and interventions) explicitly investigating TSI and TSR and their potential impact on EF and SR in children. This study aims to provide information as to which specific aspects need to be examined more closely, instructing further development and implementation of efficient and effective interventions in education.

Introduction: Early relationships with teachers play an important role in children’s development and significantly influence students’ cognitive and academic performance. Studies suggest that working memory (WM) is a strong predictor of academic achievement, especially of reading and arithmetic outcomes. The associations between teacher-student relationship (TSR) quality, children’s WM skills and their academic performance have been reported in numerous observational studies. However, the potentially bidirectional and temporal nature of the relationships between these constructs is understudied.Methods: The purpose of this study was to investigate the relationships between primary school children’s WM and TSR by applying a cross-lagged design and measuring these constructs at three time points throughout the academic year. More exploratively, this study investigated how WM and TSR bidirectionally relate to children’s academic performance.Results: The findings of this study revealed a temporal relationship between WM and TSR: between WM-related problems in the classroom at baseline and conflict at 3-month follow-up, and between closeness at 3-month follow-up and WM-related problems in the classroom at 5-month follow-up. Moreover, the findings showed a bidirectional relationship between arithmetic performance and WM-related problematic behaviour.Discussion: This study highlights that relationships between the teacher and students play an important role in supporting students’ cognitive and academic development. Importantly, this study suggests that children with WM problems may benefit from interventions that focus on improving their relationships with teachers. Additionally, the findings propose that interventions targeting WM may also have positive effects on children’s academic performance.

The current qualitative study examined the teacher–student interaction and its influence on children’s working memory in primary schools in Belgium and the Netherlands. Eighteen primary school teachers participated in semi-structured interviews focusing on strategies employed to support students with working memory difficulties. The study offered a comprehensive overview of the strategies, categorised into instructional support, classroom organisation, and emotional support (based on the Teaching Through Interactions framework) that teachers use when dealing with working memory-related difficulties. Additionally, it provided unique insights into teachers’ underlying beliefs and rationales about the effectiveness of these strategies. Lastly, factors influencing the use and efficacy of these strategies (based on the Multilevel Supply–Use model) were explored. By integrating teachers’ voices and experiences, this research provides a unique opportunity to bridge theory and practice, and enrich the current understanding and interpretation of the teacher–student interaction and its implications for improving working memory performance in primary school students. Overall, the holistic approach, taking into account both direct and indirect approaches, offered a comprehensive understanding of the multifaceted challenges faced by students with working memory difficulties and the diverse strategies teachers can employ to address them, which can further inform classroom practices, professional development, and policy-making.

Working memory (WM) is crucial for learning and academic success, emphasizing the need for effective theory- and practice-informed interventions supporting children with poor WM. Given limited transferable effects, recent research stresses the importance of context, focusing on malleable environmental factors like teacher–student interaction. This study uses a microtrial approach to explore the effects of teacher-provided instructional support on children’s observable WM-related problematic behavior. The experimental group (n = 35, 42.9% girls, Mage = 8.37, SDage = 1.66) received targeted instructional support, while the control group (n = 32, 40.6% girls, Mage = 8.67, SDage = 2.03) received teaching as usual. Pre- and post-intervention comparisons examined changes in students’ WM behavior. The four-week intervention included five strategies derived from a systematic review and a qualitative study, building on teachers’ existing practices. Findings revealed a significant time × condition interaction, with reduced WM-related problematic behavior in the experimental group, showing medium to large effect sizes (η_p² = 0.08–0.20). Improvements were noted in classroom behavior and the home environment, as reported by parents blinded to the condition. This study contributes to the causal evidence base indicating that targeted instructional support can reduce WM-related challenges and highlights the potential of brief, teacher-provided classroom interventions.
