Objective: To investigate the risk factors for osteoporosis among a sample of middle-aged women. Methods: Adipose tissue and bone mineral density levels at the left femur, lumbar spine, and total body were assessed using dual-energy x-ray absorptiometry (DXA). Subjects (n=342) were surveyed regarding a variety of osteoporosis-related risk factors.…

The law of conservation of momentum can be applied to a wide range of processes whether it is the collision of subatomic particles, rocket propulsion, or the recoil of a cannon. In this experiment two technologies, the Arduino microcontroller and a PASCO smart cart, are used to create a movable rubber band launcher. The Arduino microcontroller is…

The purpose of this study was to assess the accuracy of three recommended anthropometric equations for women and then develop an updated prediction equation using dual energy x-ray absorptiometry (DXA). The percentage of body fat (%BF) by anthropometry was significantly correlated (r = .896-. 929; p [is less than] .01) with DXA, but each equation…

Electrostatic potential energy is a topic of great difficulty for many students. In this paper, we empirically test the utility of two approaches for laying a foundation for developing an understanding of energy in an electrostatic context, with interdisciplinary relevance. We examine student responses to a question about how the potential energy…

The body mass index (BMI), or the ratio of weight in kilograms to the square of height in meters, is widely used to determine the presence or absence of overweight and obesity in adults. Although many consider BMI an acceptable clinical surrogate of body fatness, it does not differentiate between fat and fat-free tissues. Thus, children and…

Current career pathways initiatives recapitulate in many ways both the issues motivating the school-to-work movement of the 1980s and 1990s and its recommended solutions, notably more work-based learning, especially apprenticeship. But that movement's energy dissipated in the face of college for all. Nonetheless, some of its achievements and many…

In this paper, we show a laboratory experience describing the possibility to build a sensor using a coil to measure small thicknesses of materials with the possibility of measuring temperature simultaneously, with the same built sensor. Its operation is based on the following facts: An electric current (a.c), flows through a coil and a magnetic…

Remote access technology in STEM education fills dual roles as an educational tool to deliver science education (Educational Technology) and as a means to teach about technology itself (Technology Education). A five-lesson sequence was introduced to 11 and 12-year-old students at an urban school. The lesson sequences were inquiry-based, hands-on,…

Research into teacher learning and practice over the last three decades shows that the teachers of a specific subject need to possess knowledge that is different from the knowledge of other content experts. Yet this specialized version of content knowledge that teachers need to plan instruction, respond to student ideas, and assess student…

The problem addressed in this study is the uniquely demanding experience of contemporaneously being a successful Olympic level athlete and a successful university level student. Due to the time and energy required for successful Olympic competition, a dual-career student-athlete may complete his/her sports career without completing her/his…

Purpose: Higher education institutions have a valuable dual role in disseminating the circular economy (CE) as a new sustainability paradigm. First, the university teaches students about this subject. Second, it prepares future teachers to incorporate sustainability into other educational levels. This paper aims to present the results of…

In this paper, we seek to evaluate the extent to which students can follow a deductive reasoning chain when it is presented to them. A great deal of instruction in introductory physics courses is centered on presenting students with a logical argument that starts from first principles and systematically leads to a particular conclusion. This…

There is a need to better understand the reality of enacting dual teaching positions, or roles, within a school. Therefore, role conflict experienced by teachers who are tasked with concurrently teaching multiple subjects warrants further understanding. For example, teachers responsible for teaching physical education (PE) and another school…

This document describes "lifetime sports" education in Pennsylvania. "Lifetime sports" is defined as individual and dual sports that increase energy expenditure and contribute to personal fitness so that people can safely pursue them throughout their life. The historical background is given for the specific program in…

The introduction of problem-based learning into K-12 science classrooms faces the challenge of achieving the dual goal of learning science content and developing problem-solving skills. To overcome this content-process tension in science classrooms, we employed the knowledge-creation approach as a boundary object between the two seemingly…
