We explore the impact of the language of instruction on academic performance of Arabic-speaking students who are expected to learn mathematics and science in and through a second language (L2). Using as a theoretical background Cummins's (1984) framework relating language proficiency to academic achievement, we provide some insights into the…

The study describes the development and preliminary psychometric validation of the Suicidal Ideation Attributes Scale-Modified (SIDAS-M), a five-item assessment of suicidal ideation for use with autistic adults.

Spatial ability has long been regarded as important in STEM, and mental rotation, a subcategory of spatial ability, is widely accepted as the cognitive ability with the largest gender difference in favor of men. Multiple meta-analyses of various tests of spatial ability have found large gender differences in outcomes of the mental rotation test…

Automated writing evaluation (AWE) systems are developed based on interdisciplinary research and technological advances such as natural language processing, computer sciences, and latent semantic analysis. Despite a steady increase in research publications in this area, the results of AWE investigations are often mixed, and their validity may be…

Students who experience mathematics anxiety have long been suggested to engage in avoidance behaviors that negatively impact their mathematics performance. However, little is known about how these avoidance behaviors manifest for highly anxious students within the context of a mathematics course. Since the use of effortful study strategies has…

Languaging--that is, using language to mediate thinking, orally or in writing--facilitates second language (L2) learning. As languaging requires the deliberate, analytical action of L2 learners, learners with higher language aptitude are likely to benefit more from languaging than those with lower aptitude. Thus, this study investigated the extent…

This study aimed to review the validity and/or reliability of light-intensity physical activity (LPA) questionnaires and identify the most suitable questionnaires for measurement of LPA in adults. Following the PRISMA-P 2020 guidelines, we searched MEDLINE, PsycINFO, CINAHL, Scopus, Embase, and MedNar. Only studies that targeted adults [greater…
