The purpose of this article is to give the intelligible procedure for undergraduate students to grasp proof of the fact that the magnetic field outside the hollow superconducting sphere (superconducting shell) coincides with the field of a point magnetic dipole both when an uniform external magnetic field is applied as when a ferromagnetic sphere…

Formative assessment strategies are used to direct instruction by establishing where learners' understanding is, how it is developing, informing teachers and students alike as to how they might get to their next set of goals of conceptual understanding. For the science classroom, one rich source of formative assessment data about scientific…

This paper presents a teaching experiment that explores the levitation of a disc of ferromagnetic material in the presence of the magnetic field produced by a single electromagnet. In comparison to the classical experiment of the levitation of a sphere, the main advantage of the proposed laboratory bench is that the uniform magnetic field…

Despite their long history and importance in the American curriculum, music programs must constantly justify their place in the twenty-first century. Urban areas that are economically depressed sometimes may not be able to offer music instruction due to the emphasis on raising test scores as well as unfavorable economic conditions that may limit…

The study of the ideal solenoid is a common topic among introductory-based physics textbooks and a typical current arrangement in laboratory hands-on experiences where the magnetic field inside a solenoid is determined at different currents and at different distances from its center using a magnetic probe. It additionally provides a very simple…

This qualitative study explored elementary assistant principals' perspectives on their role and responsibilities. Online interview questions, focus group interviews and review of documents were the source of data for this study. The study produced seven emergent themes: School Operational Management, Daily Discipline Management, Teacher Support…

Improving academic achievement for students of color has long been the subject of debate among advocates of education reform (Anyon, 2013; Breitborde & Swiniarski, 2006; Payne, 2008). Some scholars have advocated for the Montessori method as an alternative educational approach to address some chronic problems in public education (Lillard,…

This phenomenological study examined the experience of fostering creativity and creative thinking in the classroom under high-stakes testing conditions, as described by teachers at a magnet elementary school in Central California. The tensions between standardization and professionalism, as well as performativity and creativity, served as the…

Catt's anomaly is a sort of "thought experiment" (a "gedankenexperiment") where electrons seem to travel at the speed of light. Although its author argued with conviction for many years, it has a clear and satisfactory solution and it can be considered indubitably just an apparent paradox. Nevertheless, it is curious and…

Objective: Less than half of young people in the USA are meeting the daily physical activity requirements of at least 60 minutes of moderate or vigorous physical activity. A mixed-methods pilot feasibility assessment of "Move it Move it!" was conducted in the Spring of 2014 to assess the impact of a before-school physical activity…

Montgomery Count Public School (MCPS) has experienced substantial demographic change since magnet and special academic programs began in the 1970s. MCPS is experiencing tremendous growth of approximately 2,500 students per year, with the fastest growing segment of students being Latino. Similar to many other districts that created magnet programs…

This report examines current educational options for U.S. students and the challenges of ensuring that choices are equally available and offer high-quality education. The report suggests what state policymakers can do to create high-quality opportunities that offer each family a system of schools worth choosing. The analysis starts from the…

Causality in electrodynamics is a subject of some confusion, especially regarding the application of Faraday's law and the Ampere-Maxwell law. This has led to the suggestion that we should not teach students that electric and magnetic fields can cause each other, but rather focus on charges and currents as the causal agents. In this paper I argue…

Charges and fields in a straight, infinite, cylindrical wire carrying a steady current are determined in the rest frames of ions and electrons, starting from the standard assumption that the net charge per unit length is zero in the lattice frame and taking into account a self-induced pinch effect. The analysis presented illustrates the mutual…

During a final seminar with BA year 4 science specialist trainee teachers, the authors posed a question about the difficulties associated with understanding magnetism. The ensuing discussion focused on a number of concerns commonly identified by students, which may also be of interest to classroom teachers teaching magnetism. Issues raised…
