The covariant formulation of Maxwell's equations can be expressed in a form independent of the usual systems of units by introducing the constants alpha, beta and gamma into these equations. Maxwell's equations involving these constants are then specialized to the most commonly used systems of units: Gaussian, SI and Heaviside-Lorentz by giving…

The field of electrical and computer engineering has evolved significantly in the past two decades. This evolution has broadened the field of ECE, and subfields have seen deep penetration into very specialized areas. Remarkable devices and systems arising from innovative processes, exotic materials, high speed computer simulations, and complex…

President Obama said in his 2011 State of the Union address that the United States is experiencing a second "Sputnik Moment," implying that the country is challenged to keep up with its international competitors in training scientists and engineers. A recent review of academic performance rated the United States 17th in reading, 23rd in science,…

Polymers are materials with vast environmental and economic ramifications, yet are generally not discussed in secondary education science curricula. We describe a program in which college mentors develop and implement hands-on, polymer-related experiments to supplement a standard, state regents-prescribed high school chemistry course, as well as a…

Background/Context: Within the context of four locally funded research projects, the researcher was asked to disseminate the findings of her narrative inquiries not to the research community, which had previously been the case, but to the practice and philanthropic communities. This, in turn, created a representational crisis because practitioners…

Changes to Title IX allowing the growth of single-sex schools have garnered media attention promoting the benefits of separating boys and girls. Alternately, civil rights groups such as the ACLU continue to oppose any type of school segregation. Within this context, a private philanthropy, the Foundation for the Education of Young Women (FEYW) has…

As a nation, society benefits from an educated populace. At a time when economic, environmental, social, and security issues are the focus of many conversations in businesses, industries, government offices, schools, and homes, policymakers turn their attention to the further development of human capital. Educators acknowledge that they have key…

This study documented curriculum decisions made by an eighth grade social studies teacher as he prepared students for their high-stakes test. When considering how to best meet students' needs, the teacher described tensions between the pressures of standards and testing and his commitment to cultural responsiveness. Perceptions about these…

Although many national studies have been conducted on the effectiveness of magnet programs, there is limited research involving math, science, and technology magnet schools and their influence on student academic performance, especially at the middle school level. The purpose of this study was to determine whether a statistical difference existed…

An experiment and a demonstration concerning transport by magnetic levitation (Maglev) are described. The lift, drag and radial forces on a magnet placed over a rotating conducting disc are measured versus the rotation frequency. The experiment relates to important topics of electromagnetism and could be a useful addition to the undergraduate…

This efficacy study was designed to examine the traditional FOSS curriculum (Delta Publishing, Full Option Science System/FOSS, magnetism and electricity, structures of life, and water modules, 2005), and the new ASK/FOSS curriculum (magnetism and electricity, structures of life, and water modules, 2005), a revised version of the original FOSS…

This study examined three high schools in a large urban school district in Texas that achieved an academically acceptable rating after being sanctioned to reconstitute by state agencies. Texas state accountability standards are a result of the No Child Left Behind Act of 2011 (NCLB). Texas state law requires schools to design a reconstitution plan…

The equations of motion for electromechanical systems are traced back to the fundamental Lagrangian of particles and electromagnetic fields, via the Darwin Lagrangian. When dissipative forces can be neglected the systems are conservative and one can study them in a Hamiltonian formalism. The central concepts of generalized capacitance and…

For most students, classes in the arts are more than just a means of gathering credits, they are about getting involved in what the students like, at least for a period. They feel that the classes are a healthy escape, a time to recuperate and do what they do well. In the art classrooms, music studios, and video labs, students feel they are part…

The Sun's atmosphere is a highly structured but dynamic place, dominated by the solar magnetic field. Hot charged gas (plasma) is trapped on lines of magnetic force that can snap like an elastic band, propelling giant clouds of material out into space. A range of ground-based and space-based solar telescopes observe these eruptions, particularly…
