Simple Experiments To Help Students Understand Magnetic Phenomena, Kerry Browne, David P. Jackson Oct 2007

Simple Experiments To Help Students Understand Magnetic Phenomena, Kerry Browne, David P. Jackson

Faculty and Staff Publications By Year

The principles of magnetism are a common topic in most introductory physics courses, yet curricular materials exploring the behavior of permanent magnets and magnetic materials are surprisingly rare in the literature. We reviewed the literature to see how magnetism is typically covered in introductory textbooks and curricula. We found that while most texts contain a relatively complete description of magnetism and its relation to current-carrying wires, few devote much space to the development of a model that explains the magnetic phenomena students are most familiar with, e.g., the interaction between permanent magnets and ferromagnetic materials. We also found that ...


Strongly And Weakly Directed Approaches To Teaching Multiple Representation Use In Physics, Patrick B. Kohl, David Rosengrant, Noah D. Finkelstein Jan 2007

Strongly And Weakly Directed Approaches To Teaching Multiple Representation Use In Physics, Patrick B. Kohl, David Rosengrant, Noah D. Finkelstein

Faculty Publications

Good use of multiple representations is considered key to learning physics, and so there is considerable motivation both to learn how students use multiple representations when solving problems and to learn how best to teach problem solving using multiple representations. In this study of two large-lecture algebra-based physics courses at the University of Colorado (CU) and Rutgers, the State University of New Jersey, we address both issues. Students in each of the two courses solved five common electrostatics problems of varying difficulty, and we examine their solutions to clarify the relationship between multiple representation use and performance on problems involving ...


Are You What You Eat? An Inside Look At High-Tech Food, Roxanne Greitz Miller Jan 2007

Are You What You Eat? An Inside Look At High-Tech Food, Roxanne Greitz Miller

Education Faculty Articles and Research

If we abide by the familiar saying "you are what you eat," it is understandable that people may be concerned with the incredible advances in food science technology and their possible impacts on human health. For example, in recent years high-tech scientific processes such as genetic modification, irradiation, and cloning have all been used to increase the safety of food supply, create foods that are more appealing to eat and easier to produce, and increase crop yields. This article will summarize a few hot topics in food science, address what is currently known about the safety of these processes, and ...
