This paper integrates technology, in the form of a physics simulation; science concepts, via image formation by lenses; and a mathematics apparatus, in the form of rational functions. All constituents merge into an instructional unit that can be embedded into a high school or undergraduate mathematics or physics course. The cognitive purpose of…

Martha Whiteley (1866-1956) was one of the most important women chemists in the United Kingdom in the first half of the 20th century. In a male-dominated field, she was an academic on the staff of a co-educational university, Imperial College, London, where she carried out research of her own choosing, rather than assisting a male professor. She…

This article gives a brief history of fire-walking and then deals with the physics behind fire-walking. The author has performed approximately 50 fire-walks, took the data for the world's hottest fire-walk and was, at one time, a world record holder for the longest fire-walk (www.dwilley.com/HDATLTW/Record_Making_Firewalks.html). He currently…

A low-cost portable fluorimeter was constructed using a 360 nm LED for excitation and a silicon photodiode for detection. The instrument is simple to operate and has been used to investigate fluorescent whitening agents extracted from various brands of paper, to determine the linear range and limit of detection of quinine in various commercial…

This qualitative action research study examined teachers' perceptions of leadership, research-based practices, and experience. I investigated how these three factors influenced the culture and change process at one suburban high school in order to better understand the context and to ultimately use the knowledge gained to improve the culture…

Positive psychology is a rapidly expanding area of study that is of great interest to students at the graduate, undergraduate, and high school levels. But the field is so broad that teachers who want to cover all the bases when designing a positive psychology course may have difficulty locating and selecting materials. "Activities for Teaching…

Predicting student success has long been a question of interest for postsecondary admission counselors throughout the United States. Past research has examined the validity of several methods designed for predicting undergraduate success. High school record, standardized test scores, extracurricular activities, and combinations of all three have…

A rotating magnetic field is the basis for the transformation of electrical energy to mechanical energy. School experiments on the rotating magnetic field are rare since they require the use of specially prepared mechanical setups and/or relatively large, three-phase power supplies to achieve strong magnetic fields. This paper proposes several…

A transition can be described as a change, a switch, a move, or a conversion to another place or frame of mind. Eastern Kentucky University (EKU) has implemented a transition project serving middle and high school students with disabilities. Each year, hundreds of students are provided with information and activities designed to stimulate their…

A constrained elastic pendulum is proposed as a simple mechanical model for the isotropic harmonic oscillator. The conceptual and mathematical simplicity of this model recommends it as an effective pedagogical tool in teaching basic physics concepts at advanced high school and introductory undergraduate course levels. (Contains 2 figures.)

The trajectories of the molecules in an ideal gas and of the ball in a soccer game are compared. The great difference between these motions and some similarities are discussed. This example could be suitable for discussing many concepts in kinetic theory in a way that can be pictured by students for getting a more intuitive understanding. It could…

This mixed-methodological study explored the factors that predict a student's likelihood to complete an undergraduate program in a STEM discipline at one campus reliant upon that mission. Offered in response to a national imperative for the U.S. to compete globally, researchers contend educators must better prepare a STEM foundation and inspire…

This report uses statistics to examine current conditions and changes over time in education activities and outcomes for different racial/ethnic groups in the United States. This report shows that over time, students in the racial/ethnic groups of White, Black, Hispanic, Asian, Native Hawaiian or Other Pacific Islander, American Indian/Alaska…

Excelencia in Education is committed to using data to inform public policy and institutional practice to achieve our mission of accelerating student success for Latinos in higher education. Every educational experience from early childhood to high school and into the workforce influences the potential for college success. For this reason, this…

In section two of a 2002 amendment on the Undergraduate Science, Mathematics, Engineering, and Technology Education Improvement Act, congress stated "A workforce that is highly trained in science...is crucial to generating the innovation that drives economic growth..." (Committee on Science, 2002). Given the growth in science,…
