Background: Loneliness during adolescence has adverse consequences for mental health, education and employment outcomes. Yet, we know little about common correlates of loneliness among adolescents, making intervention work difficult. Aims: In this study, we (1) explore individual-, school- and country-level correlates of loneliness to help…

Performance on lab assessments of executive functions predicts academic achievement and other positive life outcomes. A primary goal of research on executive functions has been to design interventions that improve outcomes like academic achievement by improving executive functions. These interventions typically involve extensive practice on…

This study aimed to examine the impact of different motivational strategies on learning outcomes and explore the interaction effects between these strategies and graduate students' motivational orientations. As a result of the study, the use of external rewards had a positive effect on learning outcomes for learners with extrinsic motivation, but…

The potential benefits and mechanistic effects of working memory training (WMT) in children are the subject of much research and debate. We show that after five weeks of school-based, adaptive WMT 6-9 year-old primary school children had greater activity in prefrontal and striatal brain regions, higher task accuracy, and reduced intra-individual…

Metacognition, the ability to think about and regulate one's thinking, is an important factor in effective student learning. One intervention to promote student metacognition is the exam wrapper--a reflection students complete after an exam noting how their performance related to their preparation. Results are mixed on the effect of the exam…

This study employed a meta-analytic approach to examine the effectiveness of graphic organizers (GOs) in improving academic and behavioral outcomes for K-12 students with disabilities, drawing from the single-case special education literature. Moderators at participant and study level were analyzed in addition to the main effects. A comprehensive…

The present research examined the extent to which the initial approach to a research-writing course by STEM and non-STEM second-language learners may entail the contribution of different dispositions to course performance and ultimately be responsible for dissimilar outcomes. Individual differences in dispositions and behavior were assessed during…

This dissertation consists of two chapters on topics in economics of education. In the first chapter, I develop and estimate an equilibrium model of endogenous instruction and student effort in order to empirically investigate the relationship between instructional choices, classroom composition, and student achievement in elementary school. The…

Childhood obesity is a prevalent health condition, the effects of which extend to mental health, social relationships, educational performance, and long-term physical health conditions. The present study focused on an optimized student support intervention that functions in predominantly high-poverty urban locations, which recognizes students as…

Widely implemented in Europe over the last three decades, Content and Language Integrated Learning (CLIL) has been researched in some European contexts more extensively than in others, with the Norwegian context being among the least represented. This paper attempts to contribute to filling in the gap by examining the impact of a short-term CLIL…

Despite great attention and numerous efforts across countries to reduce school dropout, it remains a persistent challenge. One such initiative, named New Possibilities, launched by the Norwegian Ministry in 2010, was a nationwide, flexible program aimed at providing intensive training to poor achievers during the last months of 10th grade, before…

We discuss task-value interventions as one type of relevance intervention and propose a process model of value reappraisal whereby task-value interventions elicit cognitive-affective responses that lead to attitude change and in turn affect academic outcomes. The model incorporates a metacognitive component showing that students can intentionally…

This investigation employed a longitudinal design to examine the influence of a one-shot growth mindset intervention on ninth-graders' implicit beliefs about intelligence and related achievement goals in four different samples. The intervention conformed to characteristics of 'wise interventions'. Participants' incremental beliefs about…

Brief, targeted self-affirmation writing exercises have recently been offered as a way to reduce racial achievement gaps, but evidence about their effects in educational settings is mixed, leaving ambiguity about the likely benefits of these strategies if implemented broadly. A key limitation in interpreting these mixed results is that they come…
