A group of 26 high-school physics teachers completed a card-sorting task to prioritize their choices of topics to include in the physics curriculum. Mechanics, electricity, and magnetism emerged as most important. Covering these topics conflicted with teachers' goals to impart deep conceptual understanding of physics in their students. (33…

Describes equipment used for a magnetic force experiment that is capable of producing precise results but rugged enough to withstand handling by several hundred undergraduate students per year. (WRM)

Describes an alternative set-up for demonstrating Lenz's Law in which the magnet can be seen during its fall. (WRM)

In recent years, parents have benefited from a significant expansion of educational options for their children. Parents have many more opportunities than just a few years ago to choose from an array of public school options, including charter, virtual, and magnet schools. Expanding educational options for parents is one of the hallmarks of the…

The after-school science club at Galtier Math, Science, and Technology Elementary Magnet School in St. Paul, Minnesota, learned some valuable lessons when they took newfound knowledge about pollution into their homes. After learning about the effects of various contaminants on health and what informed citizens can do about it, students tested…

Describes a simple and inexpensive model to demonstrate the pulsed magnetic resonance phenomenon. Gives the details of construction of the device which can provide a direct demonstration of the precessional motion of a magnetic moment in a steady magnetic field. (Author/GS)

The purpose of this research was to examine policies and curriculum practices in performing arts secondary schools in the United States. Data were obtained from a survey (including questionnaires, opinionnaires, interviews, and observations) conducted among 55 schools (total number existent in 1980) and visits to 11 selected institutions in the…

This report contains detailed descriptions of three program recommendations regarding public school choice. The recommendations are a result of a study conducted by the New Jersey Department of Education, in which public school choice and magnet schools were examined. The three recommended programs described are (1) Intradistrict Choice Program;…

In the teaching of physics, the study of electricity and magnetism typically follows the introduction of the basic concepts of mechanics. However, there are some new concepts associated with electromagnetic fields that seem at first to the student to be unrelated to, or even incompatible with, Newton's third law as learned in mechanics.…

Describes the magnetic field of Helmholtz coils qualitatively and then provides the basis for a quantitative expression. Since the mathematical calculations are very involved, a computer program for solving the mathematical expression is presented and explained. (GS)

Optical and electromagnetic fundamentals are presented in this fourth unit of the Project Physics text for use by senior high students. Development of the wave theory in the first half of the 19th Century is described to deal with optical problems at the early stage. Following explanations of electric charges and forces, field concepts are…

The unit presented in this teacher's guide is one of two developed for the sixth and final year in the Science Curriculum Improvement Study (SCIS) curriculum. The concept of a scientific model is introduced in this unit with activities directed toward increasing student understanding of electric and magnetic phenomena through concrete experience…

Four study segments of the Self-Paced Physics Course materials are presented in this eighth problems and solutions book used as a part of course assignments. The content is related to magnetic induction, Faraday's law, induced currents, Lenz's law, induced electromotive forces, time-varying magnetic fields, self-inductance, inductors,…

Discusses the principle of generating electron beams, some of their current applications as a high energy content source, and their potential for technological development. (GA)
