A physical pendulum with a magnetic load is proposed for comparison of linear and nonlinear oscillations. The magnetic load is repelled by permanent magnets which are disposed symmetrically relative to the load. It is established that positions of the pendulum and the magnets determine the dependence of restoring force on displacement of the load.…

This study aims at diagnosing which subjects pre-service physics teachers have difficulty understanding in introductory physics courses and what accounts for these difficulties. A questionnaire consisting of two qualitative questions was used to collect data for this study. The questionnaire was administered to 101 pre-service physics teachers who…

In this paper, we describe how simple experiments realizable by using easily found and low-cost materials allow students to explore quantitatively the magnetic interaction thanks to the help of an Open Source Physics tool, the Tracker Video Analysis software. The static equilibrium of a "column" of permanents magnets is carefully investigated by…

A thematic course called "Climate Change: Chemistry and Controversy" was developed for upper-level non-STEM students. This course used the socioscientific context of climate change to teach chemical principles and the nature of science. Students used principles of agnotology (direct study of misinformation) to debunk climate change…

Physics is essential for students who want to succeed in science and engineering. Excitement and interest in the content matter contribute to enhancing this success. We have developed a laboratory experiment that takes advantage of microwave ovens to demonstrate important physical concepts and increase interest in physics. This experiment…

The author recently had the same conversation about local school reform with two superintendents--one from a large, urban district in the East and the other from a small district in the Midwest. Both superintendents were working with their respective boards to approve, design and fund reading initiatives consistent with the new federal guidelines.…

This report describes the characteristics of the 100 largest public elementary and secondary school districts in the United States and its jurisdictions. These districts are defined as the 100 largest according to the size of their student population. The information in this report was provided by state education agency officials to the National…

The Japanese educational reform movement is concentrating on increased individuality, lifelong learning, and the need to cope with societal changes, notably internationalization and the spread of information media. The American education system is admirable for experimenting with dropout programs, awards for improved student performance, magnet…

Three magnet middle schools which were established as part of a voluntary desegregation plan in a school system in a large, American city are described in this report. The schools are examined as organizations that differed in their innovative educational approaches to bring about desegregation. One school offered a system of open education, in…
