This study investigates how individual-level factors contribute to classroom engagement variations of boys and girls across the elementary school years. Classroom engagement was assessed four times between the ages of 7 and 12 years in a large, representative population-based sample (N = 877) using latent growth modeling. Predictors included the…

In some tracked educational systems, track recommendations are formulated by primary school teachers to determine the secondary school level that students will be allocated to. While teachers mostly base their track recommendations on students' prior achievement, the extent to which teachers also consider perceived student attributes, such as…

Purpose: The probability of a child reading a word correctly is influenced by both child skills and properties of the word. The purpose of this study was to investigate child-level skills (set for variability and vocabulary), word-level properties (concreteness), word structure (mono- vs polymorphemic), and interactions between these properties…

To inform teaching practices, we examined elementary learners who were anxious-withdrawn within their naturally occurring affiliation groups at school. Hypotheses addressed the degree to which affiliation group characteristics moderate the relation between individual levels of anxious-withdrawal and internalizing distress. Data from 447 fourth and…

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…

The influence of individual difference variables on second language (L2) listening comprehension has been an area of research that has been gaining renewed attention in recent years. The current study investigated the effects of two cognitive variables, aptitude and metacognitive awareness, on 107 native-Korean, English as a foreign language…

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…

This study evaluates the interpersonal problem-solving abilities of 5-8 years old children in terms of different variables. The differentiation of interpersonal problem solving skills of 5-8 years old children attending preschool and 1st grade of primary school according to the demographic characteristics (child's gender, parents' age, parents'…

Conjunctions facilitate text cohesion and comprehension by making explicit the logical relationships between ideas in written language. Conjunctions may be challenging for English language learners (ELLs) because of their novel, abstract, and text-connecting role. In this longitudinal study we aimed to clarify the connections among comprehension…

The present study longitudinally investigated proportional reasoning abilities in early elementary school before the start of its instruction. Three aims were put forward: (a) distinguishing the different developmental states in young children's understanding of missing-value proportional situations, (b) investigating how children transition…

This research synthesis examined the impact of grades, comments, and no performance feedback on academic motivation and achievement in elementary and secondary school. Four meta-analyses were conducted, with two each exploring the impact of (a) grades versus no performance feedback and (b) grades versus comments on academic motivation and…

This study explores factors that predict students' self-assessment intentions and practices using a framework based on the Theory of Planned Behaviour (TPB). A total of 1425 Hong Kong students (Primary 4 to Secondary 3) participated in this study. Students' intentions and practices pertaining to self-assessment and the predictors of their…

We examined the contribution of a major predictor of basic literacy ability--phoneme awareness--to individual differences in two arithmetic computation tasks: a speeded task consisting of simple computation problems (arithmetic fluency) and an untimed, more complex computation task involving multi-digit operands (numerical operations). The…

This study examined Spanish spelling errors among 166 native Spanish-speaking students from Kindergarten to Grade 3 based on a spelling-to-diction task. Fifteen types of spelling errors were analyzed in a latent class analysis. Results suggested three phases of spellers: Phase 1 students had a high chance of committing almost all types of errors.…

Research on the implementation of CLIL at the onset of primary school is limited and has largely overlooked the role of other sources of individual differences. This study investigated the effects of the CLIL approach to English learning, together with the effects of out-of-school exposure to the language through media and other sources of…
