The author was born and raised in rural, northern Mississippi. He went to a local school, the North Pontotoc Attendance Center, from first grade on. The author was always interested in math and science, but, then, he was interested in most all subjects. The expected path that his friends and siblings had followed was clear: attend a junior college…

Laboratory and practical courses, where students become familiar with experimental techniques and learn to interpret data and relate them to appropriate theory, play a vital role in chemical education. In the large panoply of currently available techniques, it is difficult to find a rational and easy way to classify the techniques in relation to…

The November 13, 2009 Conference of the National Coalition on School Diversity brought together more than 300 people from across the nation. This included parents, teachers, school administrators, local and state elected leaders, long time civil rights advocates, community organizers, and government officials. Participants engaged in a…

Drawing on data collected during the second year of a longitudinal qualitative study that followed over 10 Latino/a bilingual students, this article foregrounds the experiences of participants during their sixth-grade year. The principle data sources included structured and unstructured interviews with teachers and students, school observations,…

Idealized models are often used in introductory physics courses. For one, such models involve simple mathematics, which is a definite plus since complex mathematical manipulations quickly become an obstacle rather than a tool for a beginner. Idealized models facilitate a student's understanding and grasp of a given physical phenomenon, yet they…

Applications of a simple approximation of Bessel functions of integer order, in terms of trigonometric functions, are discussed for several examples from electromagnetism and optics. The method may be applied in the intermediate regime, bridging the "small values regime" and the "asymptotic" one, and covering, in this way, an area of great…

Given the importance of teachers to student learning, it is important to understand how schools of choice differ in terms of the types and uses of human capital inside schools. Despite research that highlights important differences in the qualifications and staffing practices of schools of choice, there is no evidence about whether observed…

Suggests a first-order experiment that can be used to establish the Lorentz transformation without considering the constancy of light velocity or the full set of Maxwell's equations. Involves the use of a long solenoid to create an electric field in a moving magnetic field. (LC)

Contends that the equations of electromagnetism, whether in rationalized or non-rationalized form, express an invariant set of physical relationships. The relationships among corresponding symbols are given and applied to precise statements about the relation between the oersted and the amphere per meter, the abampere and the ampere, etc.…

The Walt Disney Magnet School Tot Lot, part of the school and park complex in Chicago, is designed for younger children. (Author/MLF)

This article is intended as a guide for teaching geomagnetism in a high school or university introductory physics class. Many students find this subject fascinating. Instructors, however, often have a difficult time introducing this topic at an elementary level. Suggestions will be made on how to accomplish this using three electricity and…

In the so-called electric Aharonov-Bohm effect, a quantum interference pattern shift is produced when electrons move in an electric field free region but, at the same time, in the presence of a time-dependent electric potential. Analogous fringe shifts are observed in interference experiments where electrons, travelling through an electrostatic…
