Background: Adaptive expertise is a highly valued outcome of mathematics curricula. One aspect of adaptive expertise with rational numbers is adaptive rational number knowledge, which refers to the ability to integrate knowledge of numerical characteristics and relations in solving novel tasks. Even among students with strong conceptual and…

Background: Creativity requires both divergent and convergent thinking. Previous research established that "divergent" thinking relates to mathematics performance, but generally ignored the role of "convergent" thinking and, hence, leaves it unclear how both might interact when children work on mathematical tasks. This study…

Background: Parents, teachers, and researchers all share the goal of optimizing students' academic engagement (Handbook of social influences in school contexts: Social-emotional, motivation, and cognitive outcomes, 2016, Routledge, New York, NY). While separate lines of research have demonstrated the importance of high-quality relationships and…

Background: Despite the fact that literacy instruction is a main focus of primary education, many children struggle to meet nationally set standards. Aims: We aimed to test which components of a comprehensive reading programme (ABRACADABRA:…

Background: Students form interpersonal and intrapersonal classroom social experiences with peers. While diverse intervention programmes have been developed, few have integrated social-emotional learning into academic activities to maximize the potential for learning and development. Aims: This study examined the effects of collaborative…

More needs to be known about the benefits and risks to the development of interpersonal and intrapersonal skills in ubiquitous digital environments at school and at home. Nine to 12-year-old students (n = 186) in a 1:1 digital programme serving low SES and culturally diverse communities rated their self-regulation and social skills for both…

Background: Attention-deficit hyperactivity disorder (ADHD) is a risk for learning. Because ADHD commonly includes behaviours of inattention and behaviours of hyperactivity/impulsivity, how the two types of behaviours independently affect children's academic competence remains poorly understood. Aims: To investigate the impact of behaviours of…

Background: Teaching and caring for pupils during the COVID-19 pandemic has been a challenge for many teachers, and its impact on teachers' mental health and well-being (MHWB) should be of great national and international concern. Aim and participants: This study examines 24 primary and secondary school teachers' MHWB experiences across three time…

Background: Online multiple-text comprehension is a key skill of the 21st Century, yet the study of its relations with boredom in young students has been disregarded. Boredom is an achievement emotion expected to be predicted negatively by antecedents like control and value appraisals and to be associated to a negative performance. Notwithstanding…

Background: Younger children are increasingly using social networking sites (SNS; Ofcom, Children and Parents: "Media Use and Attitudes Report," 2019, https://www.ofcom.org.uk/__data/assets/pdf_file/0020/108182/children-parents-media-use-attitudes-2017.pdf). In doing so, they may experience both benefits (e.g., enhanced social capital)…

Background: Since scholastic well-being is connected with intrinsic motivation, positive emotions and effective learning, it is highly relevant for educational research. It is influenced by a variety of individual and contextual determinants and differs for several groups of students with respect to their environmental conditions. Aims: Up to now,…

Background: Math anxiety (MA) and math achievement are generally negatively associated. Aims: This study investigated whether and how classroom engagement behaviors mediate the negative association between MA and math achievement. Sample: Data were drawn from an ongoing longitudinal study that examines the roles of affective factors in math…

Background: When exposed to evaluative situations, up to 40% of students develop test anxiety, reflected, namely, by extensive worry, intrusive thoughts, and physiological arousal. Though the negative influence of test anxiety on later school performance is well documented, the role of students' initial achievement in the development of later test…

Background: Students vary in their initial achievement when they enter school and their rate of academic growth as they move through school. These differences have implications for classroom instruction and educational policy. Although previous research has examined initial achievement and growth differences, a gap remains in understanding how…

Background: The Incredible Years® (IY) Teacher Classroom Management (TCM) programme may reduce disruptive behaviour in the classroom and improve child and teacher mental health; however, few studies have considered how acceptable TCM is to teachers or what facilitators and barriers there are to its implementation. Aims: In this paper we examine…
