The number of African Americans and Latino/as receiving undergraduate and advanced degrees in computer science is disproportionately low. And relatively few African American and Latino/a high school students receive the kind of institutional encouragement, educational opportunities, and preparation needed for them to choose computer science as a…

The 2016 Education Choice and Competition Index (ECCI) is the fifth release of an annual compilation of data on the condition of K-12 school choice in the geographical areas served by the nation's 100 largest school districts. The ECCI captures information on: (1) the extent of choice; (2) the characteristics of the process by which parents and…

The movement towards the use of the history of science and problem-based approaches in teaching serves as the impetus for this paper. This treatise aims to present and examine episodes in the lives of prominent scientists that can be used as resources by teachers in relation to enhancing students' interest in learning, fostering skills about…

The introduction of force at age 14-16 years is considered, starting with elementary student experiments using magnetic force fields. The meaningless use of terms such as "action" and "reaction", or "agent" and "receiver" is discussed. (Contains 6 figures.)

Double-exposure holographic interferometry is applied to measure the "linear" or "longitudinal" magnetostriction constant of a soft-ferrite rod. This high-accuracy measurement is done indirectly, by measuring the small rotations of a lever in contact with the rod using double-exposure holographic interferometry implemented with a robust…

The gravitational redshift forms the central part of the majority of the classical tests for the general theory of relativity. It could be successfully checked even in laboratory experiments on the earth's surface. The standard derivation of this effect is based on the distortion of the local structure of spacetime induced by large masses. The…

The deregulation movement has impacted the social, political, and economic landscape in the United States and continues to do so. In this article, we briefly summarize the general history of deregulation in this country and the meaning of deregulation within the specific context of education policy and reform. We focus on deregulation efforts…

Based on our experience of teaching physics in middle and senior secondary school, we have found that students have difficulty in reasoning at the microscopic level. Their reasoning is limited to the observational level so they have problems in developing scientific models of magnetism. Here, we suggest several practical activities and the use of…

The internal/external frame of reference and the big-fish-little-pond effect are two major models of academic self-concept formation which have considerable theoretical and empirical support. Integrating the domain specific and compensatory processes of the internal/external frame of reference model with the big-fish-little-pond effect suggests a…

Paramagnetic and diamagnetic materials are now generally known as the "Cinderella" materials of the magnetic world. However, susceptibility measurements made on these materials in the past have revealed many details about the molecular bonding and the atomic structure of the so-called "transition" elements. Indeed, the magnetic moment of neodymium…

This article comes from a question asked by a student of mine: if the Sun radiates energy in the form of electromagnetic waves, could they shift the Earth from its current orbit on a suitable timescale? The answer to such a question is apparently obvious and trivial. Nevertheless, it requires an instructive reasoning and interesting estimates of…

This paper is designed to specify a set of new opportunities for educators, school administrators, and scholars to realize the practical aims and strategic advantages envisioned in magnet schools. The paper is divided into three distinct sections. In Section I, we examine the extensive research literature on parents' choice patterns and…

The purpose of this study was to investigate the influence of supervised mentorship in an authentic-context learning setting on music education graduate students' graduate school experiences. Participants were six current and former graduate music education majors who acted as supervised mentors to undergraduate students teaching instrumental…

According to Section 29.123 of the Texas Education Code, the "Texas State Plan for the Education of Gifted/Talented Students" (G/T) forms the basis of program accountability for state-mandated services for G/T students. In the Houston Independent School District (HISD), G/T students were served through one of two program designs:…

Prior research has contributed to our understanding about the ways teachers communicate their expectations to students, how students perceive differential teacher behaviors, and their effect on students' own perceptions of ability and achievement. Despite more than half a century of this work, historically marginalized students continue to be…
