A way to promote student interest and engagement in physics is by capitalizing on students' skills in arts and crafts to design and make physics-based toys. This article illustrates how two students (averaging 14 years of age) in the authors' science class designed and fabricated a variation of a physics-based teaching aid that demonstrates the…

We describe the kinematics, dynamics, and also some energy issues related to Marta mouse's motion when she walks on top of a horizontal bicycle wheel, which is free to rotate like a merry-go-round, as presented recently by Paul Hewitt in the "Figuring Physics" section of this journal. The situation is represented in Fig. 1, which was…

The effect of concurrent movement on incidental versus intentional statistical learning was examined in two experiments. In Experiment 1, participants learned the statistical regularities embedded within familiarization stimuli implicitly, whereas in Experiment 2 they were made aware of the embedded regularities and were instructed explicitly to…

Contrasting reports of "reduced" and "intact" sensitivity to coherent motion in autistic individuals may be attributable to stimulus parameters. Here, we investigated whether dot lifetime contributes to elevated thresholds in children with autism. We presented a standard motion coherence task to 31 children with autism and 31…

When eating cereal for breakfast, it is common to observe how cereal pieces move to the walls of the bowl. The same thing occurs when having tea--the small leaves tend to move toward the cup walls. While the suspension of objects on liquids due to surface tension is usually discussed in introductory physics courses, this phenomenon is not usually…

In our first article on scaling in theropod dinosaurs, the longitudinal stress in the leg bones due to supporting the weight of the animal was studied and found not to control the dimensions of the femur. As a continuation of our study of elasticity in dinosaur bones, we now examine the transverse stress in the femur due to locomotion and find…

The bounce of a ball is a seemingly innocuous event that can be used to illustrate many aspects of elementary and even advanced mechanics. Both normal and oblique bounces on a rigid surface are considered in this article, emphasizing qualitative features of the bounce process. If the ball bounces at an oblique angle then it can slide throughout…

This study proposed a video-based reflective learning approach using motion-tracking sensors to facilitate the learning of tennis skills in a college physical education class by beginning players. The motion-tracking sensors, synchronized with a smartphone video application, were attached to tennis rackets for collecting the students' shot-data.…

This paper reports a case study of four grade 10 physical sciences teachers' PCK about graphs of motion. We used three data collection strategies, namely teachers' written accounts, captured by the content representation (CoRe) tool, interviews and classroom observations. We conceptualised the PCK displayed in the CoRe tool and the interviews as…

The present study investigates the features of teacher-children interaction during whole-class activities within an early childhood community, in which children's active participation is supported. The theoretical basis of the study is shaped by sociocultural approaches, which consider learning as a process of social co-construction of meanings,…

Background: Recent critiques of twenty-first century physical education (PE), and by association physical education teacher education (PETE), position the discipline as largely uncontested, unproblematised and uncritical. This critique encourages researchers to re-consider the nature of PE and what it means to move, be moved, value movement or be…

This study explores how Korean English learners process English caused-motion constructions (CMC) through online and offline experiments. The focus was on how Korean learners' processing of English CMC is affected by the typological difference between English and Korean. Of the 77 volunteer participants recruited, 17 were native English speakers…

Embodied mathematics activities involve students engaging in physical actions to help them better understand mathematics concepts. Current research shows these types of activities have great potential to help students develop conceptual understanding. The authors present four principles for designing embodied mathematics activities and give…

Introduction: Braille readers encounter difficulties when reading mathematical expressions. In this exploratory study, we created a setting to investigate these difficulties. Method: Using a motion-capturing system, we analyzed the tactile strategies of three braille readers while they read mathematical expressions. To compare tactile with visual…

Before infants produce words, they can discriminate changes in motion event components such as manner (how an action is performed) and path (trajectory of an action). Individual differences in nonlinguistic event categorization are related to children's later verb comprehension (Konishi, Stahl, Golinkoff, & Hirsh-Pasek, 2016). We asked: (a) Do…
