Science, technology, engineering, and mathematics (STEM) courses are considered to be challenging for students and may present unique challenges for each domain. This study addresses a gap in the research literature by investigating the challenges students face in general and organic chemistry lecture courses. Students provided information…

Cognitive performance is both heritable and sensitive to environmental inputs and sustained practice over time. However, it is currently unclear how genetic effects on cognitive performance change over the course of learning. We examine how polygenic scores (PGS) created from genome-wide association studies of educational attainment and cognitive…

Spina bifida (SB) refers to a subgroup of congenital defects where the neural tube fails to fuse, often resulting in a protruding spinal cord. This is often due to a defect or absence of vertebral arches resulting from a failure of the mesoderm to organize over the region of the defect. SB occurs during gestation between the third and sixth week…

Predictors of expressive grammar were compared in formal and naturalistic assessment tasks for children with typically developing (TD) language and with Developmental Langauge Disorder (DLD). Standardized expressive language assessments were administered to 110 preschoolers. The parents of these children reported whether or not they were concerned…

The aim of this study was to determine the relationship between language learning strategies of secondary school students and the concept of academic self. The study was carried out with 522 students enrolled in an Anatolian high school in the central district of Ankara. In the study, Personal and Academic Self-Concept Inventory (PASCI), which was…

The present study aimed to examine how visual skills, verbal working memory, visuospatial working memory, and other general cognitive skills (inhibitory control, attention, and decision speed) were simultaneously correlated with the early acquisition of reading among kindergarten children. A total of 99 Chinese children were tested individually on…

Nonverbal Learning Disability (NLD) has been the focus of four decades of neuropsychological research. However, it has yet to be included as a diagnostic category in the Diagnostic and Statistical Manual of Mental Disorders (i.e., currently in its fifth edition, DSM-5, American Psychiatric Association, 2013). Many of the characteristics associated…

Background: Being aware of the different social expectations linked to the principal lifespan stages (i.e., childhood, adulthood, old age) is critical to an individual's inclusion in the community and to developing appropriate social behaviours. However, little research exists on this topic in the field of intellectual and developmental…

This study examined the persistent problem of practice that ELLs are not identified for gifted programs at the same rate as their native English-speaking peers. The purpose of this research study was to investigate the relationship among English language proficiency levels and general intellectual ability of English language learners for gifted…

Divergent thinking (DT) is considered as an indicator of creative potential and a predictor of creative achievement. Furthermore, it is also conceptualized as an indicator of cognitive reserve (CR) in healthy elderly. CR refers to a functional benefit that can potentially offer protection against brain pathologies and is thereby considered a…

In co-located, multi-user settings such as multi-touch tables, user interfaces need to be accessible from multiple viewpoints. In this project, we investigated how this goal can be achieved for depictions of data in bar graphs. We designed a laboratory task in which participants answered simple questions based on information depicted in bar graphs…

Previous research has documented reliable effects of teachers' judgments or expectations, respectively, on their students' school performance. However, the importance of those effects has been controversially discussed because of their limited effect size. The impact of teacher judgments on students' lives might have been underestimated due to a…

Judgments of learning (JOLs), as one type of metacognitive judgments, are assessments that people make about how well they have learned material. The effective use of JOLs depends on various factors, including task-specific variables and the learner's own metacognitive resources. Little has been known about the relationship between JOL accuracy…

Theories of multilingual language learning often assume that previous language learning experiences in at least two languages provide advantages for additional language learning. Other research emphasises the importance of general cognitive abilities as predictors of language learning. We test whether a set of predictions based on a multilingual…

This study investigated first-year undergraduate statistics students' statistical problem-solving skills on the probability of the union of two events, conditional probability, binomial probability distribution, probabilities for x-limits using the z-distribution, x-limit associated with a given probability for a normal distribution, estimating…
