Discusses superconducting microelectronics based on the Josephson effect and its advantages over conventional integrated circuits in speed and sensitivity. Considers present uses in standards laboratories (voltage) and in measuring weak magnetic fields. Also considers future applications in superfast computer circuitry using Superconducting…

This evaluation provides an overview of demographic characteristics and student achievement outcomes among Wake Country Public School System (WCPSS) elementary schools when these schools are categorized as schools of choice (program magnets and calendar magnets) or traditional schools (nonmagnets). Data were drawn from school-level outcomes…

The policies and practices that shape magnet schools are examined, and the meaning and importance of magnet schools are explored. The chapters are: (1) "School Choice in the Public Arena"; (2) "The Context of Magnet Schools: The Policies and Politics of Desegregation in Cincinnati and St. Louis"; (3) "Magnet Schools and the Social Context of…

We examine whether school quality affects passing the California High School Exit Exam (CAHSEE), which is a standards-based high-stakes performance assessment. We use 3-level hierarchical logistic and linear models to examine student probabilities of passing the CAHSEE to take advantage of the availability of student, teacher, and school level…

This textbook presents elementary principles of mechanics, hydrostatics, hydraulics, pneumatics, acoustics, pyronomics [sic], optics, electricity, galvanism, magnetism, electromagnetism, magneto-electricity, and astronomy. Among topics covered are descriptions and illustrations of McCormick's reaper, Sharps' Rifle, printing presses, House's…

This textbook is a course in natural science and astronomy. The contents include mechanical properties of bodies; mechanics of solids; mechanics of fluids; nature and production of sound; nature and transmission of light; excitation and characteristic effects of electricity; properties and magnets; theoretical astronomy; and descriptive astronomy.

Describes a number of simple experiments and demonstrations useful in secondary school science teaching. (AL)

Discusses varied roles a qualitative researcher or ethnographer plays in the educational research process. Focuses on ways in which these different roles affect others' behavior in the presence of the ethnographers; how ethnographers interact; and how ethnographers interpret, analyze, and present data. (Author/MJL)

Discusses the role of the Francis Bitter National Magnet Laboratory of the Massachusetts of Technology, and its significance in the world of research. Applications of research on magnetism to medicine are emphasized. (SA)
