Although acoustics examples and demonstrations can be an effective tool for engaging students in introductory physics classes and outreach, teaching principles of sound and vibration to the deaf and hard of hearing needs to be approached carefully. The deaf and hard of hearing have less intuition with sound but are no strangers to some of the…

A recent note in this journal presented a demonstration of standing waves along a cord consisting of two parts having different material densities, showing different sized wavelengths in each part. A generalization of that experiment to a continuously varying linear mass density is to vibrate a strip of material with gradually varying width (mass…

An operational understanding of Newton's third law is often elusive for students. Typical examples of this concept are given for contact forces that are closer to the students' everyday experience. While this is a good thing in general, the reaction force can sometimes be taken for granted, and the students can miss the opportunity to really think…

In my previous article on apparatus named after physicists and physics teachers, I discussed five relatively common pieces of apparatus from the 1875-1910 era. Now I will go back to the 18th and early-19th centuries to discuss eponymous apparatus that we are still using in lecture demonstrations. [For Part I, see EJ912907.]

It's always hard to know what to expect when bringing computers into an educational setting, as things are always changing. Student skills with computers are different today than they were 10 years ago, and 20 years ago almost counts as an alien world. Still, one hopes that some of these changes result in positive trends, such as student attitudes…

Interactive lecture demonstrations (ILDs) are a powerful tool designed to help instructors bring state-of-the-art teaching pedagogies into the college-level introductory physics classroom. ILDs have been shown to improve students' conceptual understanding, and many examples have been created and published by Sokoloff and Thornton. We have used the…

Special events like science days, teacher's meetings and physics recruiting efforts require spectacular and, if possible, interactive experiments for the audience. Based on past experience with such events, we have gathered and present here a series of demonstration experiments in mechanics, optics, waves and electricity which are suitable, and…

Describes several outstanding high school physics programs and analyzes the reasons for their success. This analysis suggests a set of conditions for creating successful programs at other schools. A list of goals for successful physics programs is included. (JN)

Twenty secondary physics teachers from southeast Michigan participated in a National Science Foundation Honors workshop on excellence in physics teaching. Presented are the classroom practices, important resources, and roles for good programs they identified and their recommendations for improving student/counselor/administrator perceptions of…

The 1982 Search for Excellence in Science Education project has identified 50 exemplary programs in physics, chemistry, biology, and earth science. Descriptions of four of these programs and the criteria used in their selection are presented. The first section reviews the direction established by Project Synthesis in searching for exemplary…

The National Diffusion Network (NDN) is a federally funded system that makes exemplary educational programs available for use by schools, colleges, and other institutions. This publication contains information describing the science education programs currently in the NDN, along with procedural information on how to access these programs. The…

The Search for Excellence in Science Education was inaugurated in 1982 to carry out the National Science Foundation's 1981 initiative, Project Synthesis. The Search establishes criteria for excellence and applies them to actual programs in one or several fields each year. In each area the Search identifies hallmarks of excellence in terms of…
