We empirically examined the effectiveness of how the Analysis of Competing Hypotheses (ACH) technique structures task information to help reduce confirmation bias (Study 1) and the portrayal of intelligence analysts as suffering from such bias (Study 2). Study 1 (N = 161) showed that individuals presented with hypotheses in rows and evidence items…

This small-scale, qualitative study uses educational design research to explore how focusing on argumentation may contribute to students' learning to engage in inquiry independently. Understanding inquiry as the construction of a scientifically cogent argument in support of a claim may encourage students to develop personal reasons for adhering to…

Child temperament has long been viewed as a potential susceptibility factor in the link between parenting and child disruptive behavior (CDB). Specifically, the idea is that children with higher negative emotionality, surgency, and lower effortful control are more affected by their received parenting, but experimental evidence is scarce. Also,…

Making better decisions typically requires obtaining information relevant to that decision. Adolescence is marked by increasing agency in decision-making and an accompanying increase in impulsive decisions, suggesting that one characteristic of adolescent decision-making is a tendency to make less-informed decisions. Adolescents could also be…

This paper adds to the literature on the relationship between procrastination and academic performance. We measure procrastination as the speed with which students do an online math course on the ALEKS learning platform. This pre-admission course is mandatory for students that are weak in math. Using a large dataset of undergraduate students at a…

Technology presents incredible new potential in opening 'learning to earning' pathways for traditionally marginalised groups, such as displaced young people, adolescent girls and young women. Developing and scaling digitally powered learning for displaced populations can provide alternative opportunities to those who have lost access public…

The persuasiveness of anecdotal evidence and statistical evidence has been investigated in a large number of studies, but the combination of anecdotal and statistical evidence has hardly received research attention. The present experimental study therefore investigated the persuasiveness of this combination. It also examined whether the quality of…

Secondary school students often only use the rules for doing scientific inquiry when prompted, as if they fail to see the point of doing so. This qualitative design study explores conditions to address this problem in school science inquiry. Dutch students (N = 22, aged 14-15) repeatedly consider the quality of their work: in a conventional,…

This paper explores students' ability to analyse and interpret empirical data as inadequate data analysis skills and understandings may contribute to the renowned disappointing outcomes of practical work in secondary school physics. Selected competences, derived from a collection of leading curricula, are explored through interviews and practical…

Increasing class size is one of the key variables that policy makers can use to control spending on education. But the consensus among many education researchers is that smaller classes are effective in improving student achievement. This view has led to a policy of class size reductions in a number of US states, the UK, and the Netherlands. This…

Purpose: Given the complexity of sentence processing and the specific problems that children with specific language impairment (SLI) experience, we investigated the time course and characteristics of semantic processing at the sentence level in Dutch preschoolers with SLI. Method: We measured N400 responses to semantically congruent and…

This article reports the results of a qualitative case study investigating the self-authorship characteristics of learners in the context of an interdisciplinary curriculum. The study identifies the students' assumptions about knowledge, self, and relationships. The findings are based on evidence from reflective essays written by students upon…

This study investigates the relationship between nonword repetition (NWR) and vocabulary in 2-year-olds. Questions addressed are whether (1) NWR and vocabulary are associated, (2) phonotactic probability affects NWR, and (3) there is an interaction effect between phonotactic probability and vocabulary on NWR performance. The general aim of the…

Public higher education institutions (PHEIs) have widely acknowledged a positive relationship between internationalization and their institutional competitive advantage enhancement. Although some concerns have been raised by practitioners and researchers about whether institutional competitive advantage can be enhanced given the current ways of…

While a growing number of longitudinal studies contribute to our knowledge on the relationship between delinquent peers and one's own delinquent behavior, researchers have generally approached the issue in a restricted way: failing to identify mediating processes or to distinguish between what peers approve of and what they do. Moreover, most…
