Chemical energy storage and use is a critical part of a sustainable world. In this laboratory experiment, students construct and use an inexpensive hydrogen fuel cell to power a calculator or a clock. The reusable cells are prepared from plastic syringes and a nickel mesh that is coated with a palladium metal catalyst by electroless deposition.…

The stately fall of magnets through conducting pipes is a favorite classroom and laboratory activity used in teaching electromagnetic induction, Lenz's law, eddy currents, electromagnetic braking, and even Newton's third law. When a neodymium magnet is used, the terminal velocity is reached in just a few milliseconds as the induced eddy currents…

How might digital technologies (DTs) support creative expression and, in the process, reframe failure as a productive feature of creative learning endeavors? The purpose of this conceptual article is to provide a way of approaching this question. More specifically, the article opens with a brief discussion highlighting how DTs have the potential…

Mass trauma events affect everyone including children. Resulting symptomatic problems for children can be addressed by clinical professionals yet at some point following these mass trauma events children must return to school but their teachers are seldom prepared to work with them to facilitate a return to learning, though they undoubtedly spend…

In this study, we examine the effect of providing examples in the responses to a question about multitasking. Respondents were randomly assigned to one of the three experimental conditions: the first group received one set of examples (watching TV or watching kids), the second group received a different set of examples (walking or talking with…

We present a classroom exercise developed to teach the tools of determining order quantities and reorder points for inventory management. This exercise presents the students with an inventory management scenario but only provides a portion of the data that are required to set order quantities and reorder points. The activity is a type of…

Pedigree analysis has long been an essential tool in human genetics as well as a staple of genetics education. Students of genetics might be surprised to learn that human pedigrees were first popularized in the United States by proponents of eugenics, the pseudoscientific social movement aimed at improving the genetic quality of the human race.…

This article is the third in a series of activities that discusses some interesting relationships with triangles. The first article (EJ1259412) introduced the various circles and centres involved with a triangle, as well as the Euler Line (named after the famous mathematician Leonhard Euler) which passes through four of the five centres. The…

This article is the fourth in a series of activities that discusses some interesting relationships with triangles. Brian Sherman shows an activity demonstrating Euler's Theorem, which gives the distance from between the circumcentre and the incentre of a triangle.

Recognizing the value of fostering students' personal and professional skills, colleges have embedded cocurricular activities into the overall students' educational experience. Activities such as cocurricular clubs are being brought to the forefront to enhance the college experience. The purpose of this extended abstract is to provide strategies…

Purpose: To validate the English version of the L'Echelle de Perception du Climat Motivational within a Portuguese context and analyze students' perceptions of the motivational climate in physical education and its relationship to demographic variables, participation in extracurricular sports, and students' grades. Methods: A total of 476…

The purpose of this study was to investigate the effectiveness of a beginning jazz improvisation learning environment for middle school instrumentalists, including whether one of two instructional sequences of harmonic form improvisation tasks better supported four outcomes: achievement, self-assessment, self-efficacy, and motivation. Over 12…

This paper investigates students' mathematical modeling activity in data-rich modeling tasks. It aims at gaining insight into how students develop meaning when modeling data-rich situations and the mathematical models produced. A tendency to model a particular dataset, rather than the phenomenon that the dataset is a particular instance of, has…

Want an innovative way to get young children moving--and support development across multiple domains? Discover CHAMPPS, the fun, effective, and research-based motor program for inclusive preschool classrooms. Filling the need for a school-based motor program designed for children with diverse abilities, CHAMPPS uses universal design for learning…

Here is presented an interesting problem that can be used to introduce students to a variety of physics topics including non-inertial frames and frictional forces, rotational dynamics, and damped oscillations; the normal force also appears, but not in its usual guises. The problem is a generalized version of problem 3.34 presented in the…
