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…

The mass of electromagnetic radiation in a cavity is considered using the correct relativistic approach based on the concept of a scalar mass not dependent on the particle (system) velocity. It is shown that due to the non-additivity of mass in the special theory of relativity the ensemble of chaotically propagating mass-less photons in the cavity…

The stereochemical features of molecules can have far reaching effects in many areas of science including medicinal chemistry, materials chemistry, and supramolecular chemistry. There have been many techniques developed over the years to determine the absolute configuration of alkenes: the R,S configuration of chiral centers and the most stable…

This study reports changes in kindergarten students' understanding of magnets after participating in a series of hands-on, inquiry-based lessons. The lessons focused on the dipole nature of magnets and employed a visual representation of a magnet as an arrow for the kindergarten students. This dipole model was used to describe how magnets interact…

We suggest the creation of a Global Web Laboratory (we call it "GloLab") for scientific purposes and teaching experiments online. In this article, we discuss the main principles and problems of building such a global Internet-laboratory. An example of a current working laboratory for teaching magnetism experiments online is also discussed.

"Alabama Education News" is published monthly except for June, July, and December by the Alabama Department of Education. This publication, authorized by Section 16-2-4 of the "Code of Alabama", as recompiled in 1975, is a public service of the Alabama Department of Education designed to inform citizens and educators about…

This paper describes and discusses the unique chemistry course opportunities beyond the advanced placement-level available at a science and technology magnet high school. Students may select entry-level courses such as honors and advanced placement chemistry; they may also take electives in organic chemistry with instrumental methods of analysis;…

In this article, the author profiles Columbus Magnet School in Norwalk, Connecticut. In 1979, Columbus School was an inner-city neighborhood school with an 87% minority population. In order to comply with federal desegregation guidelines, the school was compelled to either integrate the student body to reflect that of the larger community or close…

This study explores the relationship between interaction rituals, student engagement with science, and learning environments modeled on communities of practice based on an ethnographic study of an eighth grade urban magnet school classroom. It compares three interactional events in order to examine the classroom conditions and teacher practices…

Infrared thermal imaging is a valuable tool in physics education at the university level. It can help to visualize and thereby enhance understanding of physical phenomena from mechanics, thermal physics, electromagnetism, optics and radiation physics, qualitatively as well as quantitatively. We report on its use as lecture demonstrations, student…

This document is a compilation of the presentations made at the Conference on Magnet Schools for Desegregation held in the Fall of 1977. It provides an overview of many types of magnet school programs and their degree of success. Presentations include a paper on the Federal government and magnet schools; some promises and cautions regarding magnet…

This study examines Emergency School Aid Act (ESAA) program operations related to school desegregation in New York and New Jersey. Included are brief discussions of application submission, grant competition, and project monitoring and technical assistance. Information presented is based on Federal and State data, program records, interviews, and…

This monograph was written for the conference on the New Instructional Materials in Physics, held at the University of Washington in summer, 1965. The approach is phenomenological and microscopic, and is intended for college students who are not preparing to become professional physicists. The monograph has three sections. Section I includes a…

For nearly four decades, magnet schools have been an important element of American public school education. They have offered innovative programs not generally available in local schools and provided opportunities for students to learn in racially diverse environments. Magnet schools have been particularly important in districts that are trying to…
