We conducted a study with introductory and upper-division physics students in a Mexican university to learn how students independently recognize the electric field's main characteristics in the electric field lines diagram and as a source or target representation in conversion processes. We used the theory of registers of semiotic representations…

Conducted for Arnold Ventures by Abt Associates, the "New Mexico Charter School Study: Findings Report" collates the results of Abt's evaluation of numerous charter schools in the state, several of which employ a whole-school dual language model. The study also created multiple logic models for use by practitioners, policymakers, and…

For the past several years, leaders in middle grades education research have strengthened their call for more methodologically robust quantitative research to address important questions in the field. Recently, two important routes towards addressing this call have emerged: the Middle Grades Longitudinal Study from the National Center for…

Since the early 1990s when the nation's first charter school was opened in Minneapolis, the scope and availability of school-based options to parents has steadily expanded. No longer can public education be characterized as a monopoly. Sponsored by the National Center on School Choice (NCSC), this handbook makes readily available the most rigorous…

A classical Greek elementary magnet school in a large urban school district has identified the need for a multicultural fine arts program reflecting the contributions of ancient cultures to modern man. The author and teachers (K-5) of this school developed a multicultural program using classical literature, visual and performing arts, history, and…

The purpose of this research was to examine policies and curriculum practices in performing arts secondary schools in the United States. Data were obtained from a survey (including questionnaires, opinionnaires, interviews, and observations) conducted among 55 schools (total number existent in 1980) and visits to 11 selected institutions in the…

Describes experiments used during recent history to explain the nature of the quantum world. Explains the essential elements of experiments using polarized light and magnetic flux. Illustrates differences between classical theories in physics and quantum theory. Shows how experiments in the microscopic and macroscopic world appear to support…

The study was conducted in a major United States city which was under a court order to desegregate its schools. The school district responded by establishing a series of magnet schools. This method was designed to bring whites voluntarily into movement for desegregation. Three middle schools were studied to assess the relationship between teachers…

Describes the change of earth's magnetic field at the boundary between the outer core and the mantle. Measurement techniques used during the last 300 years are considered. Discusses the theories and research for explaining the field change. (YP)

Discussed is a common error made by students in judging the distribution of the magnetic field of a circular loop along its diameter. Qualitative and quantitative explanations of the magnetic field distribution are presented. (CW)

Described are the idea of chaos and the ability to control the chaotic behavior of a real-world physical system. Included is an explanation of the methodology and applications in biology and chemistry. (KR)

In recent years, parents have benefited from a significant expansion of educational options for their children. Parents have many more opportunities than just a few years ago to choose from an array of public school options, including charter, virtual, and magnet schools. Expanding educational options for parents is one of the hallmarks of the…

This position paper on the concept of an international high school is primarily concerned with two questions: (1) What constitutes a "region"? (2) What are the ingredients of a "center"? Demographic changes and declining resources are serious obstacles confronting efforts to create new institutions, and logistical demands are underrated by…

A majority of the school districts that desegregate use magnet schools as part of their effort. Magnet schools offer enriched academic or vocational programs to attract committed students whose neighborhood schools do not offer the coursework and activities they seek. This paper is concerned with science magnet schools. This study was designed to…

The purpose of this study was to determine which magnet concepts were found in various science textbook series, how the concepts were presented, and to identify potential misconceptions related to magnets. Magnet concepts presented as prose, illustration, and/or laboratory activities are identified and analyzed. (KR)
