While previous research has highlighted the significance of pedagogical approaches such as story, embodiment, and play for young children's science learning, limited attention has been given to how these three approaches can be integrated into a learning environment to support science learning for young children. Accordingly, this study designed a…

Movement of the body is an essential way to characterise autism, according to diagnostic criteria. However, qualifying descriptions of what autistic movements are, their functions and personal value, are missing from academic literature and clinical guidance. We systematically searched for autistic adults' descriptions of their body and its…

Manual exploratory behaviors during object interaction that form the basis of tool use behavior, are mostly qualitatively characterized in terms of their frequency and duration of occurrence. To fully understand their functional and clinical significance, quantitative movement characterization is needed alongside their qualitative analysis.…

Despite the growing influence of the "material" turn within childhood studies and education, scholarship related to teaching and learning within the early childhood classroom remains a largely humanistic endeavour. By applying relational and multispecies onto-epistomologies to both children's classroom relations "and" our own…

The biological motion refers to the continuous configuration movement of live agents in space. The perceptual processing of biological motion has the specificity of the dissociation between body form and body motion. However, there is limited evidence for whether such specificity continues when holding biological motion in working memory. We…

In children with autism spectrum disorders (ASDs), assessing attention is crucial to understanding their behavioral and cognitive functioning. Attention difficulties are a common challenge for children with autism, significantly impacting their learning and social interactions. Traditional assessment methods often require skilled professionals to…

The natural development of static lower limb varus/valgus alignments during early childhood is well understood. However, our understanding of dynamic lower limb frontal plane alignments is limited, and we lack normative descriptions of this phenomenon for both boys and girls. This study investigated dynamic lower limb alignment during…

This article describes the newly developing form of poetic duets in Libras (Brazilian Sign Language). What do the two people performing a sign language duet poem do to make a duet different from a solo poem? How can we categorize their actions and the effects that these actions create? Drawing on examples of duet poems in Libras, we analyze…

The question of the sources of electric and magnetic fields and their causes has been discussed extensively in the literature over the last decades. In this article, we approach this problem from the unified treatment of electromagnetic fields emphasizing the role of their sources in accordance with the cause-effect relationships. First, we…

The purpose of this study was to explore the potential of capture systems in improving high school students' dancing skills through the use of experimental design. The major findings were as follows: First, using a MoCap system and high-speed camera to document dancers' movements can provide reference materials for students to improve their skills…

The variation of the period of oscillation of a pendulum with the amplitude is known as "circular error" to clockmakers, and can easily be observed even without modern laboratory instruments. There have therefore been many approximate formulae for the pendulum period as a function of the amplitude, but the simple equation due to Denman,…

In this note, the classical Doppler shift for some accelerated mechanical systems is considered under a common graphical approach. In one dimension, we study uniform accelerated motion and simple harmonic motion. In two dimensions, uniform circular motion and pendular motion are considered. In each case, an elementary treatment shows that the…

Friction is one of the most important forces studied in classical mechanics, and still is the subject of pedagogical literature. In a small series of problems stated below, we consider a particle sliding down a curve under the actions of gravity and kinetic friction. Unlike many of the referenced sources, we neglect the centripetal force arising…

Words influence cognition well before infants know their meanings. For example, three-month-olds are more likely to form visually based categories when exemplars are paired with spoken words than with sine-wave tones, a likely precursor to learning symbolic relations between words and their referents. However, it is unclear why words have these…

There is a close connection between simple harmonic motion and uniform circular motion. This connection is widely taught and included in standard textbooks. Here, we exploit this connection to simultaneously derive two results from introductory mechanics: the period of a mass-spring system and the centripetal acceleration formula. Previously…
