The activPAL is a widely-used measure of sedentary time but few studies have evaluated its ability to estimate physical activity intensity. This study determined the accuracy of the algorithm used by the activPAL to predict metabolic equivalents (METs) from cadence and a curvilinear cadence-METs equation individualized for height. Thirty-six…

This research characterized faculty perceptions about the role of cocurricular activities in educating civil engineering students about ethics and/or the societal impacts of engineering (ESI). Among all survey respondents--those who mentored cocurricular activities and those who did not--41% believed that undergraduate students in their program…

This chapter focuses on the learning that happens in an intergenerational music and arts intervention with pre-verbal children and elderly people with dementia. It draws on qualitative work using a posthumanist framework of observations exploring the embodied engagement of children and elderly people with instruments, space and each other and the…

Courses: Interpersonal Communication, Communication Theory. Objectives: Students improve their understanding of relational framing theory, consider features of interactions that influence message interpretation, and reflect on ways framing impacts their interactions.

Inconsistent filtering of force plate data persists in published studies. Previous evidence suggests that low pass filtering produces the largest error when calculating jump height, but used jump height from unfiltered force plate data as the criterion. This study investigated the effects of low pass filtering on jump height calculated from force…

A simple hands-on model for illustrating the concept of isotope dilution analysis (IDA) has been devised. The model consists of two sets of beads of different sizes, with one set representing atoms of the analyte and the other set representing solvent water molecules. Phase separation is mimicked by sieving the beads, and the results are detected…

Behavioral research increasingly uses accelerometers to provide objective estimates of physical activity. This study extends research on methods for collecting accelerometer data among youth by examining whether the amount of a monetary incentive affects enrollment and compliance in a mail-based accelerometer study of adolescents. We invited a…

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…
