Different molecular representations are usually used to depict the three-dimensional (3D) structure of organic compounds. Mastering the skill of interconverting one form into another is essential for students to ensure success in organic chemistry. The traditional and recently developed methods for completing such interconversions that rely on 3D…

The impact of an interactive in-class Valence-Shell Electron-Pair Repulsion (VSEPR) activity, designed and implemented by the author in her first-year undergraduate chemistry classes, was assessed through the statistical analysis of pre- and posttreatment quizzes on VSEPR theory and the analysis of questionnaires. The activity consisted of…

Intellectual disability is a serious lifelong disability that places heavy demands on society and the health system. The study was designed to determine the extent to which the intellectually challenged children are capable of improving their cognitive abilities as well as adaptive functioning through the Montessori Sensorial Training program when…

Perceived control is an important psychosocial resource for health and well-being across the lifespan. Global control (i.e., overall perceived control) decreases over time in studies following people every few years to upwards of 10 years. Changes across wider intervals of the lifespan, however, have yet to be examined. Further, how perceived…

While there is a considerable body of research demonstrating benefits of book reading, the quality and depth of engagement children experience while reading is essential to ensure positive reading experiences and outcomes. In this article we describe four dimensions of reading engagement: behavioral, cognitive, affective, and social, illustrating…

Haptic perception is used in the anatomy laboratory with the handling of three-dimensional (3D) prosections, dissections, and synthetic models of anatomical structures. Vision-based spatial ability has been found to correlate with performance on tests of 3D anatomy knowledge in previous studies. The objective was to explore whether haptic-based…

Purpose: Children progress from making grapheme-phoneme connections to making grapho-syllabic connections before whole-word connections during reading development (Ehri, 2005a). More is known about the development of grapheme--phoneme connections than is known about grapho-syllabic connections. Therefore, we explored the trajectory of syllable use…

The aim of the study is to examine the effect of sentential context on lexical ambiguity resolution in Greek adults and typically developing children. Context and word frequency are factors that can affect lexical processing, however, the role of them has not been thoroughly examined in Greek. To this aim, we assessed sentence context effects in…

The commonly used Vineland Adaptive Behavior Scales (VABS-3) divides adaptive behavior into three domains comprising three subdomains. The validity of this three-factor structure has not been explored in autistic samples, which are often heterogeneous with respect to language and IQ. Furthermore, although there are two comparable forms,…

Batting or striking with a long-handled implement is an important fundamental motor skill used in several lifetime activities. This article outlines basic movement concepts that are developed through batting and provides recommendations that can serve as both curricular options for physical education and a potential homework idea for kids to…

In this study we examined how specific personality traits are related to psychosocial adjustment in people with intellectual disability. We studied 73 students with mild intellectual disability and 25 students with moderate intellectual disability who attended special schools in Poland. Personality traits were assessed with the Revised Edward…

Students' understanding of the meaning of the equal sign develops slowly over the primary grades. In addition to updating their representations of equations to recognize that the equal sign represents an equivalence relation rather than signaling an operation, students need to move beyond full computation to efficiently solve equivalence problems.…

This study explores sex-differences in (a) rates and profiles of autism symptoms as well as in (b) the contribution of intellectual quotient (IQ) to autism symptom presentation in Down syndrome (DS). Participants were 40 males and 38 females with DS, aged 6 to 23 years. Autism symptoms were rated through the Autism Diagnostic Observation…

The article underscores that the cartographic language used in social science textbooks for primary education in Spain is unsuitable and does not meet the demands of the official syllabus. Consequently, pupil literacy in geography with regard to regional geography is markedly ethnocentric. To demonstrate this, the cartographic content of textbooks…

Over the past decade, geospatial technologies have emerged as a tool for developing spatial reasoning and cognitive processes. While the foundational Learning to Think Spatially report from the National Research Center (2006) launched research into the use of geospatial technologies in isolation, more recently, cloud-based simulation software have…
