Academic self-concept and achievement have been found to be reciprocally related across time. However, existing research has focused on self-concept and achievement scores that have been averaged over long time-periods. For the first time, the present study examined intraindividual (within-person) relations between momentary (state) self-concept…

Students' prior achievements in school have significant correlations with their later achievements. Specifically, students' prior numeracy achievement is the most important predictor of later numeracy success. However, the assessment of this predictor across gender and its trend across students' year levels is often overlooked or not adequately…

Background: Research on academic development has mainly focused on early time periods with less attention on individual differences in development in the later school years. Methods: To improve our knowledge of how students develop academically during later school years, this study used a multivariate growth model to investigate the developmental…

Past research suggests that a sense of belonging to a community is developmentally important for adolescents and affects their engagement in school, especially during the transition to high school. However, little research examines the teaching practices that simultaneously foster classroom belonging and behavioral engagement to create a classroom…

The present study explored (a) whether differences between students with and without ADHD in reading comprehension are explained by their executive functions, and (b) the unique and shared contribution of the various executive functions to reading comprehension ability. To address these questions, ninety-six adolescents with and without ADHD…

There is a lack of research on students' conceptions of giftedness and intelligence, despite recognition of their influence on real-life factors such as achievement and motivation. This paper presents a cross-sectional mixed methods study that investigated Finnish students' (age 6-16 years; N = 1282) implicit conceptions of giftedness and…

The article presents findings from a Czech environmental literacy survey conducted in 2020 on a sample of 6th (N = 3773), 8th (N = 21518), and 9th graders (N = 4368). Specifically, the effect of environmental and sustainability education (ESE) as well as the effect of gender and age on environmental knowledge, attitudes, beliefs, place attachment,…

School-based universal well-being screening is proposed within the Multi-tiered Systems of Support approach to collect data on school and individual well-being. Universal screening allows for data-based informed decision, allocating each pupil or set of pupils in universal, selective and/or indicated structured interventions and supports. However,…

Homework is a multifaceted process that involves a complex interplay of factors. However, the processes underlying homework behavior are not yet fully understood. In Study 1, we tested a model of homework processes by examining the influences and consequences of homework behavior based on 473 Chinese students. In Study 2 with 159 British students,…

This study aims to reveal high school students' learning strategies and motivation levels, the relationship between their learning strategies and motivation levels and to determine if these two variables differ according to gender and grade at school. This study was conducted in correlational survey model. Besides, "Motivation and Learning…

In the present study, we tested the hypotheses that: a) there are individual differences in secondary students' conceptual and procedural fraction knowledge, and b) these differences are predicted by students' approach (deep vs. surface) to mathematics learning. We used two instruments developed and evaluated for the purposes of the study which…

Based on the wide-ranging liberal reforms introduced in the early 1990s, Sweden has become one of the most prominent realizations of Milton Friedman's proposal for market-based schooling. From 1991 to 2012, the percentage of Swedish ninth-grade students attending independent, voucher-financed, private schools increased from 2.8% to 14.2%. A recent…

Prediction from early development to later achievement has the potential to improve clinical and educational service delivery as well as to inform developmental theory. In this longitudinal study, we asked how well can educational achievement measured in the final year (Grade 9, age 15) of compulsory education--both overall and for outcomes in the…

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…

We constructed and calibrated an instrument targeting conceptual and procedural fraction knowledge. We used this instrument in a quantitative study with 126 secondary students (7th and 9th graders), testing the hypothesis that there are individual differences in the way students combine the two types of knowledge. Cluster analysis revealed four…
