I conducted an ethnographic study, situated within the conceptual framework of Critical Race Theory, which illustrates one child’s experiences with racism. The study was conducted in an urban after-school program, and explores issues of racism in both the school and community settings. Utilizing the storytelling aspect of Critical Race Theory, I explore the racial experiences of a 12-year-old African-American girl, and the dichotomous emotions of sadness and anger that emerge. I describe the risk to this child’s emotional well-being, and suggest a need within the mental health field to create a framework to deal with the trauma caused by racism. Amy L. Masko is affiliated with the Grand Valley State University. She is a professor of English Education, preparing pre-service teachers to teach elementary literacy. Dr. Masko’s research interests are in urban education, after school programs, and multicultural education. She is also an educational consultant in the area of diversity in education and literacy education. Address correspondence to Amy L.

This paper reviews New York City Mayor Michael Bloomberg’s education reform agenda, ‘Children first’, in the light of organizational theory. I argue that this reform agenda reflects both coercive and mimetic isomorphism, as Bloomberg uses mayoral control to apply business concepts and practices to New York City’s public school system. Through participant observation in a New York City classroom and the use of secondary data, I highlight those elements of school life that thwart the standardization so essential to the mayor’s reform effort, specifically the dominant myths and fictions held by teachers.  相似文献

Herein is described the fabrication and use of a plastic multilayer 3-channel microfluidic fixture. Multilayer devices were produced by laser machining of plastic polymethylmethacrylate and polyethyleneterapthalate laminates by ablation. The fixture consisted of an array of nine individually addressable gold or gold/ITO working electrodes, and a resistive platinum heating element. Laser machining of both the fluidic pathways in the plastic laminates, and the stencil masks used for thermal evaporation to form electrode regions on the plastic laminates, enabled rapid and inexpensive implementation of design changes. Electrochemiluminescence reactions in the fixture were achieved and monitored through ITO electrodes. Electroaddressable aryl diazonium chemistry was employed to selectively pattern gold electrodes for electrochemical multianalyte DNA detection from double stranded DNA (dsDNA) samples. Electrochemical detection of dsDNA was achieved by melting of dsDNA molecules in solution with the integrated heater, allowing detection of DNA sequences specific to breast and colorectal cancers with a non-specific binding control. Following detection, the array surface could be renewed via high temperature (95 °C) stripping using the integrated heating element. This versatile and simple method for prototyping devices shows potential for further development of highly integrated, multi-functional bioanalytical devices.  相似文献

Iowa students and parents completed related attitude and belief questionnaires about school subjects. Grade K–3 students received simpler questionnaires than did Grade 4–6 students or parents. Among Grade 4–6 children, girls perceived higher competence in reading than did boys, but boys perceived higher competence in physical science. All children perceived physical science competence lower than reading or math competence. Parents perceived boys as more competent in science. Girls like reading more than boys did; boys and girls did not differ in liking of science. Grade 4–6 children also expected lower grades in and attached lower importance to physical science than to reading. Parents perceived science as more important for boys and expected higher performance of boys. Jobs related to math or science were seen as more male dominated. These results provided a more comprehensive picture of attitudes and beliefs about science in the elementary school than had existed and suggested that attitudinal gender differences related to physical science begin to develop by the earliest elementary school years. Policy implications are that intervention programs designed to promote gender equity should be extended to the early elementary school years and also should address parental attitudes. Additional implications for policy and research are discussed. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 719–747, 1999  相似文献
