Research on the division of cognitive labor has found that adults and children as young as age 5 are able to find appropriate experts for different causal systems. However, little work has explored how children and adults decide when to seek out expert knowledge in the first place. We propose that children and adults rely (in part) on…

Two families of analysis methods can be used for differential item functioning (DIF) analysis. One family is DIF analysis based on observed scores, such as the Mantel-Haenszel (MH) and the standardized proportion-correct metric for DIF procedures; the other is analysis based on latent ability, in which the statistic is a measure of departure from…

We performed a meta-analysis of dual-task experiments to assess the robustness of the effects of conducting working memory secondary tasks on arithmetic performance. Four hundred effect sizes from 21 studies from 1,049 participants were analyzed across a variety of specifications. Results revealed that increases in working memory load resulted in…

This study examined the development of prospective teachers' (PTs) understanding of productive struggle using video episodes which PTs analyzed through the lens of professional teacher noticing. Our qualitative study included 66 PTs in four sections of a semester-long mathematics content course for prospective elementary and middle school teachers…

Concept maps are used to assess and improve prospective teachers' conceptual understanding levels. In this research, the aim was to describe prospective science teachers' conceptual understanding of the atom by using concept maps. The research employed the case study approach, one of the qualitative research patterns. The research group consisted…

Objectives: The purpose of the study was to validate a measurement scale to assess self-perceived digital competencies of Mexican university students who have migrated from a mixed school-digital system to a fully digitalized educational environment because of COVID-19 confinement. The instrument was based on the European Union Digital Competence…

Spatial thinking is a crucial aspect of geography education with which all citizens should be equipped. This study employs eye-tracking technology to research strategies (their repertoire, distribution, effectiveness, and adaptiveness) used by upper-secondary students when analyzing spatial patterns with thematic maps. The results show that…

Purpose: Listeners shift their listening strategies between lower level acoustic information and higher level semantic information to prioritize maximum speech intelligibility in challenging listening conditions. Although increasing task demands via acoustic degradation modulates lexical-semantic processing, the neural mechanisms underlying…

Background: In many classrooms, science textbooks remain a significant tool, functioning in some instances as the de facto curriculum and influencing pedagogical practices. Such conventions are more noticeable in the science classrooms of developing countries, like Jamaica, because of a chronic shortage of specialist science teachers and the…

Purpose: This study investigated the effect of cognitive load (CL) on the categorical perception (CP) of Mandarin lexical tones to discuss the application of the generalized pulse-skipping hypothesis. This hypothesis assumes that listeners might miss/skip temporal pulses and lose essential speech information due to CL, which consequently affects…

A body of research indicates that the inclusion of seductive details in instructional materials negatively impacts learning. However, there is scant research that examines the format and the amount of seductive details as potential moderating factors across multiple learning outcomes. In two studies, one focused on seductive pictures and one on…

When learners can comprehend 98% or more of the tokens within a text, the lexical difficulty of the text is unlikely to inhibit reading comprehension (Schmitt et al., 2011). This phenomenon will be referred to as the Coverage Comprehension Model (CCM). The CCM is present in countless articles that describe the percentage of tokens necessary to…

Existing literature reviews of calculus learning made an important contribution to our understanding of the development of mathematics education research in this area, particularly their documentation of how research transitioned from studying students' misconceptions to investigating students' understanding and ways of thinking per se. This paper…

This paper reports on themes that arose in an investigation of university lecturers' views on the teaching of linear algebra. This focus on themes was the initial part of a study concentrating on four areas: What is important to teach in a first course in linear algebra? Are there teaching methods which are particularly suited for such a course?…

Research has uncovered a semantic cue effect for short inconsistent word problems; the presence of functionally related objects makes them easier for pupils than the presence of categorically related ones. This study builds on this result by investigating other types of problems. Variants of problems differing in a semantic cue were solved by…
