"Sexting" (electronic transmission of sexual pictures/messages) among early adolescents is associated with early sexual activity, a marker of increased sexual risk. The current study is a secondary analysis that examined the longitudinal relationship between sexting and first-time sex among a sample of early adolescents deemed "at…

Problem behaviors have often been associated with poor learning in preschool children. However, most of these studies have mainly been situated in Western contexts. The current study, based on a single case study of a Malaysian preschool, explores the link between problem behaviors and early literacy skills of preschool children aged between 4 and…

Research on self-regulated learning (SRL) in engineering design is growing. While SRL is an effective way of learning, however, not all learners can regulate themselves successfully. There is a lack of research regarding how student characteristics, such as science knowledge and design knowledge, interact with SRL. Adapting the SRL theory in the…

Human beings naturally prefer and support ingroup members more than outgroup members, but to what extent do we "morally value" equal treatment to ingroups and outgroups? Across four preregistered studies, we examined the development of "group-transcendent fairness," that is, the moral endorsement of allocating resources equally…

We compared two tools that have been used to capture the linguistic heterogeneity and achievement of students in England: the exposure-based distinction between English as an additional language (EAL) and monolingual learners, and the 2017--2018 five level teacher rating of proficiency in English (from "New to English" to…

First-year mathematics instructors at universities across North America and the globe have been noticing a decline in the mathematics skills and preparation of their incoming students, who have been failing out of first-year mathematics courses at alarming rates. Though some universities have implemented placement or diagnostic tests to measure…

Young children can exploit the syntactic context of a novel word to narrow down its probable meaning. This is "syntactic bootstrapping." A learner that uses syntactic bootstrapping to foster lexical acquisition must first have identified the semantic information that a syntactic context provides. Based on the "semantic seed…

The capacities of detecting visual regularities were tested among twenty typical (age 11.1 ± 0.32), and twenty poor (age 11.03 ± 0.28) native-Arab readers. Two stages were implemented, passive exposure to visual regularities and forced decision task. In the first stage, the participants were passively presented with four shapes; each shape was…

We present a privacy-friendly early-detection framework to identify students at risk of failing in introductory programming courses at university. The framework was validated for two different courses with annual editions taken by higher education students (N = 2 080) and was found to be highly accurate and robust against variation in course…

The architecture of sleep undergoes distinct changes during childhood and early adolescence. Slow wave sleep is involved in memory processing and may support active consolidation of newly encoded representations to support the formation of abstracted "gist" memories. Here, we examined sleep and overnight memory formation in German school…

Although the link between developmental dyslexia and visual-spatial deficit has been recurrently highlighted, the relationship between visual-spatial abilities and reading performance is still a controversial issue, considering the orthographic variability of the language being learned. This study aimed to examine whether visuo-spatial abilities…

The study investigated the effects of the use of dynamic computer visualizations (DCVs) integrated with the POE (Predict-Observe-Explain) sequence on learners' understanding and retention of solubility and on their motivation to learn chemistry. In the research, nonequivalent groups pretest--posttest control and comparison group design was used.…

Randomized A/B tests within online learning platforms represent an exciting direction in learning sciences. With minimal assumptions, they allow causal effect estimation without confounding bias and exact statistical inference even in small samples. However, often experimental samples and/or treatment effects are small, A/B tests are underpowered,…

Objective: The first aim of this study was to examine changes in freshman college students' health-enhancing physical activity (PA) and body composition across the first semester. Secondly, this study aimed to explore the role of socio-ecological variables on these processes. Methods: A sample of 166 participants (108 females, 58 males,…

Background: A significant portion of adults struggle to read at a basic level. Word reading (defined here as decoding and word recognition) appears to play a pivotal role for this population of readers; however, less is known about how word reading relates to other important semantic processes (e.g., vocabulary, sentence processing) known to…
