The observation that the shadows of objects change during the course of the day and also for a fixed time during a year led curious minds to realize that the Sun could be used as a timekeeper. However, the daily motion of the Sun has some subtleties, for example, with regards to the precise time at which it crosses the meridian near noon. When the…

With any piece of technology, there exists a learning curve where students need time to adjust to the ways in which the device works. If you struggle with having enough time for lab, it may be advantageous to have students learn how to operate one set of equipment and use that equipment as much as possible. In this article a unique application for…

The purpose of the study is to compare the ratio of lower extremity isokinetic hamstring/quadriceps ratio (H/Q), bilateral strength difference (BLD) and relative peak torques (RPT) in volleyball players according to the leagues. 101 volleyball players participated in the study (female=34, male=25 from 1st league; female=21, male=21 from 2nd…

At the introductory level, projectile motion is usually considered under the assumption of the absence of air resistance. Even the simplest case of linear drag might be beyond the students, as it requires some familiarity with differential equations. This leaves many students wondering about the effect of air resistance on the motion and the way…

Students often struggle to understand the independence of velocity vectors in two-dimensional motion. Despite seeing classic projectile demonstrations, it is probably not obvious to most new students why the path of motion is parabolic. Likewise, first-year students might not predict that the path of motion is linear in two-dimensional vector…

In the following study we investigate how young learners engage with music and movement to illustrate their understandings and connections to nature. We discover a symbiotic relationship between the performing arts, Social Emotional Learning, and Mindful Learning over the course of six months, and examine the potentials and constraints of this…

Purpose: The aim of this study was to determine changes in swimming parameters, stroke coordination, and symmetry after repeated high-intensity swimming efforts in swimmers of different performance levels and para-swimmers. Method: Forty swimmers (20 able-bodied, allocated to higher and lower performance groups--G1 and G2, respectively--and 20…

A social semiotic lens is used to characterise aspects of representational competence for a discipline such as physics, to provide science teachers with a practical suggestion about how student learning might be organised to develop representational competence. We suggest that representational competence for some areas of science can be…

We describe the development and in-class evaluation of a quantum interactive learning tutorial (QuILT) on quantum key distribution, a context which involves an exciting application of quantum mechanics. The protocol used in the QuILT described here uses single photons with nonorthogonal polarization states to generate a random shared key over a…

The focus of this study is the co-actings of a 5-year-old girl, a swing, and physical phenomena. The study explores how the swing and physical phenomena worked as co-creators of the girl's scientific explorations as well as her bodily capacities and identity construction. Empirically, the study makes use of a video sequence generated during a…

This paper demonstrated a simple experiment for determining the coefficient of rolling friction of a hollow cylinder rolling on a curved track using a smartphone's sensors. We studied theoretically and experimentally the rolling motion of a hollow cylinder uncovered and covered with various materials (synthetic leather and sponge sheets). The…

This article presents Aesthetic Experience and Global Competence, a graduate-level online course for educators in all areas, whose development was rooted in art museum education practices. The article includes details on the course, which was built around a series of group inquiries into works of art and literature related to a broad topic:…

An experiment with 72 three-year-olds investigated whether encoding events while seeing iconic gestures boosts children's memory representation of these events. The events, shown in videos of actors moving in an unusual manner, were presented with either iconic gestures depicting how the actors performed these actions, interactive gestures, or no…

Recently, Gauthier introduced a method to construct solutions to the equations of motion associated with oscillating systems into the mathematics education research literature. In particular, Gauthier's approach involved certain manipulations of the differential equations; and drew on the theory of complex variables.Motivated by the work of…

All teachers whether in teacher training, field experience, student teaching, substitute teaching or covering a class; need an arsenal of short activity breaks aimed at increasing heart rate for students, or for allowing a "brain boost" for better focus, creativity and to become more mentally productive. Brain boosters are examples of…
