Along-standing energy lab involves dropping bouncy balls and measuring their rebound heights on successive bounces. The lab demonstrates a situation in which the mechanical energy of a system is not conserved. Although students enjoyed the lab, the author wanted to deepen their thinking about energy, including the connections to motion, with a new…

Sighted speakers of different languages vary systematically in how they package and order components of a motion event in speech. These differences influence how semantic elements are organized in gesture, but only when those gestures are produced with speech (co-speech gesture), not without speech (silent gesture). We ask whether the…

Context-based learning (CBL) is advocated as beneficial to learners, but more needs to be understood about how different contexts used in courses influence student outcomes. Gilbert defined several models of context that appear to be used in chemistry. In one model that achieves many criteria of student meaning-making, the context is provided by…

This article describes how two teachers implemented a 5E lesson in a third-grade classroom where the students had been working with forces/motion and investigating things that move like pendulums, swing sets, and various toys. The lesson was included as part of a larger unit on motion. The desired outcome for this lesson was for students to…

First order processes are of paramount importance for chemical kinetics. In a well-established demonstration experiment, the flow of water out of a vertical glass tube through a capillary simulates a chemical first order process. Here, a digital version of this experiment for lecture hall demonstrations is presented. To this end, water flowing out…

In this study, we devised research design that provides pre-service teachers to effectively experience embodied geometric thinking with the goal that it will impact teachers' instruction to students in their classrooms. Using a motion-capture video game and design tool, we offered opportunities for pre-service teachers to experience of performing…

It has been illustrated several times how the built-in acceleration sensors of smartphones can be used gainfully for quantitative experiments in school and university settings (see the overview in Ref. 1 ). The physical issues in that case are manifold and apply, for example, to free fall, radial acceleration, several pendula, or the exploitation…

Although we experience motion simply as displacement, we study it through complicated concepts such as acceleration, force, and mass, departing from our everyday experience. But it looks like we can stay attached to our primordial notions of time and length without appealing to any other concepts and still have interesting results.

In teacher inquiry, the metaphor of stance is used to describe a positionality towards teaching that includes questioning classroom practices, engaging in cycles of continuous improvement, and generating knowledge. We expand the metaphor of stance to include a metaphor for complicated movements while maintaining balance -- dynamic structural…

The Virtual Laboratory was created as a complementary educational activity, with the aim of working abstract concepts from an experimental point of view. In this work, the motion of a ring rolling and slipping in front of a grid printed panel was recorded. The frames separated from this video received a time code, and the resulting set of images…

In this article Campbell and Neilson discuss several design strategies developed or adopted that were found particularly helpful when sequencing a unit that focused on learning about motion and acceleration. Students were expected to predict, observe, and explain why a ball traveled down one ramp faster than the other. Before engaging students,…

Examples of equilibrium are evident everywhere and the equilibrium rule provides a reasoned way to view all things, whether in static (balancing rocks, steel beams in building construction) or dynamic (airplanes, bowling balls) equilibrium. Interestingly, the equilibrium rule applies not just to objects at rest but whenever any object or system of…

Clinical Question: Would individuals with acquired apraxia of speech (AOS) demonstrate greater improvements for speech production with an articulatory kinematic approach or a rate/rhythm approach? Method: EBP Intervention Comparison Review. Study Sources: ASHA journal, Google Scholar, PubMed, CINAHL Plus with Full Text, Web of Science, Ovid, and…

This article is about the development of an Internet-based remotely-controlled physical experiment, this is a part of the Remotely Controlled Laboratory at the University of Applied Sciences of Cologne known as TH Köln. The main experimental set-up is based on Pohl's Torsion Pendulum which was enhanced by a PXI measurement system and a webcam. In…

This paper reports the results of a research exploring the mathematical connections of pre-university students while they solving tasks which involving rates of change. We assume mathematical connections as a cognitive process through which a person finds real relationships between two or more ideas, concepts, definitions, theorems, procedures,…
