Iniguez, J.; Raposo, V. – European Journal of Physics, 2009
In this paper we analyse the behaviour of a small-scale model of a magnetic levitation system based on the Inductrack concept. Drag and lift forces acting on our prototype, moving above a continuous copper track, are studied analytically following a simple low-speed approach. The experimental results are in good agreement with the theoretical…

Pietro, William J. – Journal of Chemical Education, 2009
Students will use the first law of thermodynamics to determine the feasibility of using corn ethanol as an alternative to fossil fuels in automobiles. Energy flow is tracked from the Sun, to photosynthesized carbohydrate, to ethanol through fermentation, and finally to work in the combustion engine. Feasibility is gauged by estimating a…

Moore, Julie A.; Chae, Boyoung – Technology, Pedagogy and Education, 2007
The purpose of this study is to understand how beginning teachers actually utilize online resources in their everyday teaching contexts. Using a qualitative interview study design, the researchers investigated beginning teachers' use of online resources in three dimensions: professional tasks, emotional/personal support, and teaching practice. The…

Schatz, Steven – Journal of Interactive Learning Research, 2006
This study examines existent and new methods for evaluating the success of information retrieval systems. The theory underlying current methods is not robust enough to allow testing retrieval using different meta-tagging schema's. Traditional measures rely on judgments of whether a document is relevant to a particular question. A good system…

Mayer, Shannon – Journal of College Science Teaching, 2008
This paper describes a debate about national fuel-economy standards for sport-utility vehicles (SUVs) used as a foundation for exploring a public policy issue in the physical science classroom. The subject of automobile fuel economy benefits from a familiarity with thermodynamics, specifically heat engines, and is therefore applicable to a broad…

Grambo, Alan A. – Tech Directions, 2007
In this article, the author describes how electronics students at Central Nine Career Center designed a kill switch circuit to stop a runaway lawnmower. This project is ideal for a career center since the electronics/robotics, small engines and horticulture classes can all work together on their respective parts of the modification, installation…

Price, Colin B. – Physics Education, 2008
Computer games such as Unreal Tournament (UT2004 and UT3) contain a "physics engine" responsible for producing believable dynamic interactions between players and objects in the three-dimensional (3D) virtual world of a game. Through a series of probing experiments we have evaluated the fidelity and internal consistency of the UT2004 physics…

Hastings, Robin – Library Journal, 2007
In December 2006, the Missouri River Regional Library (MRRL) in Jefferson City, embarked on a journey. They had been watching the Public Library of Charlotte-Mecklenburg County (PLCMC), NC, on its adventure through the wilds of Web 2.0, and they decided to follow the trail it had blazed. What PLCMC had done was pretty revolutionary. The library…

Roberts, Lissa – Science & Education, 2007
This essay details a public display of four steam engine models assembled in a Leiden orphanage courtyard in 1777. By examining the multiple purposes to which these engines were and could be put, alongside the various interests, goals and interpretations of their inventors, instructors and audience, the notion of a clear division between public…

Dooling, Thomas A. – Physics Teacher, 2007
The toy model rocket is used extensively as an example of a realistic physical system. Teachers from grade school to the university level use them. Many teachers and students write computer programs to investigate rocket physics since the problem involves nonlinear functions related to air resistance and mass loss. This paper describes a nonlinear…

Dudzinska-Przesmitzki, Dana; Grenier, Robin S. – Journal of Museum Education, 2008
The taking up of an "educative" mantle has proven to be a complex task for museums, filled with many unknown and/or misunderstood factors. Of the vast assortment of educational opportunities museums afford their adult patrons and staff, the majority fall into one or two learning categories: either they are nonformal or informal. In effort to…

Escoffery, Cam; Miner, Kathleen R.; Adame, Daniel D.; Butler, Susan; McCormick, Laura; Mendell, Elizabeth – Journal of American College Health, 2005
Use of the Internet to retrieve health information is increasingly common. The authors surveyed 743 undergraduate students at 2 academic institutions to examine their Internet use, health-seeking behaviors, and attitudes related to the use of the Internet to obtain health information. Fifty-three percent of the respondents indicated that they…

Oliver-Hoyo, Maria T.; Pinto, Gabriel – Journal of Chemical Education, 2008
This instructional resource utilizes consumer product information by which students compare theoretical stoichiometric calculations to CO[subscript 2] car emissions and fuel consumption data. Representing graphically the emission of CO[subscript 2] versus consumption of fuel provides a tangible way of connecting concepts studied in chemistry…

Blanchard, Margaret; Sharp, Jennifer; Grable, Lisa – Science Teacher, 2009
As part of the "Car Lab Project," students constructed rubber band cars, raced them, and worked through a number of automotive activities. The students engaged in this project certainly had fun, but they also used high-tech gear such as motion sensors and graphing calculators to gather data on the distance and time cars traveled and to generate…
