In this paper we investigated the contribution of a dynamic testing procedure, including multiple graduated prompts protocols, in identifying differences in need for instruction of second grade children (N = 120) with arithmetic difficulties. The training was adaptive and prompts were provided according to one of six protocols, each focusing on a…

Purpose: School leadership is fundamental in efforts to successfully implement school reform and improve student and teacher learning. Although there is an abundant amount of research on school leaders' formal training, assessment, and practice, little is known about their informal professional learning. In other words, how do school leaders learn…

Academic self-efficacy is a crucial predictor of first-year university study success, which makes it a key intended outcome of pre-university education. Students with high academic self-efficacy at the end of secondary education likely experience a better transition to university. This study aimed to investigate which factors relate to Dutch…

This paper reports on an experimental study investigating alternative communication modes to English as a Lingua Franca. The purpose was to examine the effectiveness of different modes of communication and to gain insight in communication strategies used by interlocutors to solve referential conflicts. Findings show that ELF may not necessarily be…

This study examines the use of technology for interaction by second-year college students in The Netherlands and its relationship with their integration and sense of belonging. The concepts of student integration and sense of belonging, as used in previous studies in The Netherlands, link student's persistence to their social interactions. Our…

Identity formation is one of the key developmental tasks in adolescence. According to Erikson (1968) experiencing identity uncertainty is normative in adolescence. However, empirical studies investigating identity uncertainty on a daily basis are lacking. Hence, studying individual differences in daily certainty (i.e., identity commitment levels)…

The role of grammar teaching in foreign language education is a controversial one both in second language acquisition (SLA) research and language pedagogy and, as a result, a potential source of confusion to student teachers. The objective of this study was to gain insight into the beliefs on grammar teaching of student teachers of English as a…

The present study aims to examine relations between number representations and various sources of individual differences within early stages of development of number representations. The mental number line has been found to develop from a logarithmic to a more linear representation. Sources under investigation are counting skills and executive…

Introduction: Delays in theory of mind (ToM) of children who are congenitally blind have often been attributed to the absence of visual and social experiences. However, these delays could also be partly due to neural factors. In some children, the blindness itself has neural causes (ocular-plus blindness). Children whose blindness has an…

Cognitive processes underlying a behavioural outcome (like reading ability) and the impact of familial risk (e.g., for dyslexia) have been studied in isolation. We present a novel design, linking the two avenues. How do familial influences impact on children's cognitive skills, which subsequently underlie reading development? Participants from the…

Although research has repeatedly demonstrated that adolescents' use of sexually explicit Internet material (SEIM) is related to their endorsement of permissive sexual attitudes and their experience with sexual behavior, it is not clear how linkages between these constructs unfold over time. This study combined 2 types of longitudinal modeling,…

In this study, the authors tested the effects of Tekster [Texter], a comprehensive strategy-focused writing instruction program, using a switching replication design with three measurement occassions. The program was implemented by fourth, fifth, and sixth grade teachers (N = 76) in 60 general education classrooms in the Netherlands. Students (n =…

In this paper, we investigated whether student reading comprehension could be improved with help of a teacher Professional Development (PD) program targeting goals, data use, and instruction. The effect of this PD program on 2nd- and 3rd-grade student achievement was examined using a pretest-posttest control group design. Applying propensity score…

Having a well-founded insight into the characteristics of teachers inquiry-based attitude (IA) supports operationalising IA as a learning goal in teacher education (TE). The aim of this study is to refine the notion of IA from an ill-defined global concept into something with reliable and valid characteristics. To do so, data were gathered on…

Adolescents become increasingly sensitive to social evaluation. Some previous studies have related this change to pubertal development. The present longitudinal study examined the role of sociocognitive development. We investigated whether or not the transition to recursive thinking, the ability to think about (others') thoughts, would be…
