In many high school teaching materials the force on a current-carrying wire in a magnetic field is discussed using an idea based on a so-called "catapult field" (cf. Fig. 1), an engaging depiction of magnetic forces, albeit one which, to the best of our knowledge, has neither been used in college-level educational material or scrutinized…

Earth's field nuclear magnetic resonance (EFNMR) spectroscopy offers students a unique opportunity to consolidate their understanding of NMR spectroscopic theory through hands-on practice with a simple spectrometer. A comprehensive, 6 h experiment is presented for the introduction of low-field NMR techniques, covering spectroscopy, relaxivity, and…

In this chapter text-based learning approaches have been highlighted by innovative and time economic way to enhance the interest of students who belong to the paranoia zone in Electronic Structure of Atoms and Molecules beneath Inorganic Chemistry of chemical science. In this pedagogical survey, I have tried to hub two (02) time economic…

A vectorial representation of the full sequence of events occurring during the 2D-NMR heteronuclear single-quantum correlation (HSQC) experiment is presented. The proposed vectorial representation conveys an understanding of the magnetization evolution during the HSQC pulse sequence for those who have little or no quantum mechanical background.…

After the discovery that superconducting magnets could levitate diamagnetic objects, researchers became interested in measuring the repulsion of diamagnetic fluids in strong magnetic fields, which was given the name "The Moses Effect." Both for the levitation experiments and the quantitative studies on liquids, the large magnetic fields necessary…

This article examines several readily available "magic tricks" which base their "trickery" on physics principles, and questions the use of the word "magic" in the 21st century, both in popular children's science and in everyday language. (Contains 18 figures.)

Nationwide, magnet programs enroll more than twice the number of students served by charter schools, making them the most popular form of school choice. Across the U.S., over 1.5 million U.S. children attend magnet schools. In Miami-Dade County Public Schools, over 42,000 students are enrolled in magnet programs. The bulk of this report focuses on…

As a nation, society benefits from an educated populace. At a time when economic, environmental, social, and security issues are the focus of many conversations in businesses, industries, government offices, schools, and homes, policymakers turn their attention to the further development of human capital. Educators acknowledge that they have key…

As students advance in their education, the use of stories and specifically the process of storytelling often wane from the central mode of learning to be replaced with more didactic methods and content-driven applications. However, the use of stories has remained a central component of moral/ethics education and continues to be used as a…

The study investigated the impact on student motivation and understanding of magnetism of teaching sequences based on an inductive approach. The study was conducted in large lecture classes. A pre- and post-Conceptual Survey of Electricity and Magnetism was conducted with just fewer than 700 Thai undergraduate science students, before and after…

Magnetic braking is a long-established application of Lenz's law. A rigorous analysis of the laws governing this problem involves solving Maxwell's equations in a time-dependent situation. Approximate models have been developed to describe different experimental results related to this phenomenon. In this paper we present a new method for the…

A series of magnet trade books were analyzed against a validated list of magnet concepts (Barrow, 1990a) and their Flesch (1974) Readability was determined. These trade books were used to supplement a second grade unit on magnetism locally constructed from AIM's "Mostly Magnets" (1991). All trade books accurately described how like and unlike…

Pay for Performance (PFP) is once again gaining popularity within education. This study examines teacher attitudes toward PFP policies, and how these views vary by teacher experience, subject area specialization, grade level(s) taught, educational background, risk and time preferences, and feelings of efficacy. Data were collected through a…

In spite of a widespread commitment to the comprehensive high school, the nation has long had specialty or theme schools and schools that target particular children. Magnet schools, alternative schools, and Catholic schools illustrate that the idea of specialized schools is not new. Recently, the concept has received a boost from a study by the…

This paper reports on a 3-year study of a half-day urban magnet high school founded upon a desire to provide rigorous science, math, and technology experiences to students who would not otherwise have access to such educational opportunities. Using the theoretical lens of how a model of an educated person gets culturally produced within the school…
