Psychological and behavioral variance can be explained by differences in the environment, and between and within individuals. Almost 60 years ago, Cronbach (1957) called for converging investigations into all three sources as important for the development of accurate science and useful applications in the real world. Yet rifts among researchers…

Individual differences in executive functions (EF) are heritable and predictive of academic attainment (AA). However, little is known about genetic contributions to EFs or their genetic relationship with AA and intelligence. We conducted genome-wide association analyses for processing speed (PS) and the latent EF measures of working memory (WM)…

Although abundant research has demonstrated associations between psychologically controlling parenting and adolescent problem behavior, little is known about the moderating role of adolescent personality herein. This study examined whether adolescent personality moderates the associations between parental psychological control and internalizing…

According to several developmental theories some children are more sensitive to the quality of their environment than others, but most supporting empirical evidence is based on relatively distal markers of hypothesized sensitivity. This study provides evidence for the validity of behaviorally observed Environmental Sensitivity as a moderator of…

Previous studies have examined learner factors such as anxiety, self-efficacy, and achievement motivation in ESL/EFL (English as a second language/English as a foreign language) writing.

Context: Each country has a unique history in the development of its athletic training professionals and education and credentialing systems. In Japan, the majority of athletic trainers hold a domestic credential (JSPO-AT) obtained from the Japan Sport Association (JSPO) or a US-based credential from the Board of Certification (BOC-AT). Objective:…

This paper argues that professional discourse relating to subject knowledge for primary teaching is less than coherent in the context of initial teacher training (ITT). This study explored the ways in which the term subject knowledge was conceptualised and interpreted by beginning primary teachers. The research was conducted across two ITT…

The Rapid Assessment of Cognitive and Emotional Regulation (RACER) is a tablet-based assessment tool for children that measures executive function (EF) skills. Instructions that are brief and visually presented; game-like tasks are designed to easily engage children regardless of literacy level and variable test administration settings. RACER…

Contribution: Prior studies on tangible versus graphical user interfaces have reported controversial findings concerning children's preferences. This paper shows that their preference profiles in the domain of introductory programming are associated with gender and age for both interfaces. Background: The relevant literature mainly consists of…

The purpose of this study was to investigate whether college students' attitudes toward group work could be influenced by thoughtful group project design. Undergraduate students (N = 123) in a lifespan human development course were assigned to groups and asked to create a smartphone app for a specific life stage. The authors utilized a convergent…

The effectiveness of remedial mathematics courses in post-secondary education has been a controversial topic for years. Higher Education institutions need their students to have basic understandings of the subjects to be imparted in the first semesters, but since they come with different backgrounds and prior knowledge, this is not always possible…

Experts claim that individual differences in children's formal understanding of mathematical equivalence have consequences for mathematics achievement; however, evidence is lacking. A prospective, longitudinal study was conducted with a diverse sample of 112 children from a midsized city in the Midwestern United States (M[subscript age] [second…

More than 30 of the 43 universities in Australia offer an exercise science and/or sport science degree programs. In the Vocational Education and Training (VET) sector, more than 160 Registered Training Organisations offer Australian Government approved fitness training courses. The paper is a self-reflective exercise based upon mentoring placement…

Background: Using data from a statewide relationship education (RE) program targeting a diverse adolescent sample, this study examined RE implementation in classroom environments. Objective: The purpose of this study was to explore (1) whether there is a beneficial RE program effect for change in individual attitudes toward sexual delay, (2)…

This study compares a problem-solving account of discovery through writing, which attributes discovery to strategic rhetorical planning and assumes discovery is associated with better quality text, to a dual-process account, which attributes discovery to the combined effect of 2 conflicting processes with opposing relationships to text quality.…
