Scientific reasoning helps children understand the world around them. Teaching scientific reasoning can be challenging because not all component scientific reasoning skills develop at the same age and not all children learn these skills at the same pace. Adaptive support thus seems called for. We designed two types of adaptive instruction, based…

To draw valid and reliable conclusions from child studies involving facial expressions, well-controlled and validated (child) facial stimuli are necessary. The current study is the first to validate the facial emotional expressions of child models in school-aged children. In this study, we validated the Radboud Faces Database child models in a…

Background: The present study examined patterns and predictors of reading comprehension growth in first language (L1) and second language (L2) readers in the upper grades of primary school. Previous research suggests that L1 and L2 readers differ in their growth trajectories and that differences in language proficiency play a role in this.…

The widely supported wish for more inclusive education places ever greater expectations on teachers' abilities to teach all children, including those with special needs and challenging behaviours. The present study aimed at the question whether teachers judge pupil behaviour more negatively if there are more children with difficult behaviour in…

In this study, an educational development approach is investigated aiming at improving reading comprehension outcomes in primary education through inquiry and design-based Science & Technology teaching. The context is societal pressure to increase the likelihood that more students, later in their life, will aspire for careers in…

In this paper, we extend a mixed method (MM) approach to lesson observation and analysis used in previous research in England, combining multiple structured observation instruments and qualitative field notes, to provide a framework for studying three videotaped lessons from 3rd-grade US mathematics classrooms. Two structured observation schedules…

The school closures owing to the 2020 COVID-19 crisis resulted in a significant disruption of education provision, leading to fears of learning losses and of an increase in educational inequality. This article evaluates the effects of school closures based on standardised tests in the last year of primary school in the Dutch-speaking Flemish…

Stability is an important underlying assumption in any form of assessment-supported decision-making. Since early years development is frequently described as unstable, the concept plays a central role in the discussion surrounding early years assessment. This paper describes stability as a set of assumptions about the way individual scores change…

The aim of this observational study is to explore how history teachers promote historical contextualisation in their lessons. Historical contextualisation is the ability to situate phenomena and individuals' actions in the context of time, historical location, long-term developments, or specific events to give meaning to these phenomena and…

This study investigated (1) the extent to which presentations of measurement error in score reports influence teachers' decisions and (2) teachers' preferences in relation to these presentations. Three presentation formats of measurement error (blur, colour value and error bar) were compared to a presentation format that omitted measurement error.…

Purpose: The aim of this study is to measure the concurrent validity of the Athletic Skills Track (AST) by examining whether its outcome score correlates with the holistic judgments of experts about the quality of movement. Method: Video recordings of children performing the AST were shown to physical education teachers who independently gave a…

Scientific reasoning refers to the thinking skills involved in conceiving and conducting an investigation. This study examined how proficiency in performing these skills develops during the upper-elementary school years. A sample of 157 children (age 7-10) took a performance-based scientific reasoning test in three consecutive years. Four distinct…

Scientific reasoning is an important skill that encompasses hypothesizing, experimenting, inferencing, evaluating data and drawing conclusions. Previous research found consistent inter- and intra-individual differences in children's ability to perform these component skills, which are still largely unaccounted for. This study examined these…

In the last two decades Dutch primary school students scored below expectation in international mathematics tests. An explanation for this may be that teachers fail to adequately assess their students' understanding of learning goals and provide timely feedback. To improve the teachers' formative assessment practice, researchers, curriculum…

Children tell prosocial lies from the age of three years onward, but little is known about for whom they are inclined to lie. This preregistered study examined children's (N = 138, 9-12 years) prosocial lying behavior toward minimal in-group and out-group peers. Additionally, children evaluated vignettes in which an in-group peer told a prosocial…
