ABSTRACT Cities in the United States and across the world have experienced gentrification at the same time as school choice policies have become more popular. This research examines the relationship between gentrification and charter schooling, seeking to understand how together they affect demographic composition of schools across Washington, DC. This study uses geographic information systems (GIS) mapping and statistical techniques to show that gentrified neighborhoods are more likely to have charter schools. Additionally, the demographic compositions of charter schools and traditional public schools differ depending on the gentrification classification of the census tract in which the schools are located. While a handful of diverse charter schools exist in gentrified neighborhoods and some diverse public schools exist in traditionally affluent neighborhoods, schools in Washington, DC remain racially and economically isolated overall. 相似文献

Differential Grading Standards Revisited 总被引:2,自引:0,他引:2
The differential grading standards described by Goldman and Widawski (1976) exist in the same magnitude and in roughly the same order a decade later in a different kind of institution. Major fields that attract as majors students who score higher on SATs employ stricter grading standards. These differential grading standards serve to attenuate the correlation between SAT scores and grades, which is, even in highly selective institutions, substantial. 相似文献

The association of reading disability with perceptuomotor problems has had a chequered history. This study examines the relationship between a new test of ocular dominance and reading and spelling ability in a group of 323 schoolchildren. Similar rates for unfixed ocular dominance were found for poor readers as in comparable studies. The rates of unstable ocular dominance did not differ between those with reading and spelling difficulties and controls. These findings in a ‘blind’ study question the role of this test of eye dominance as a diagnosis of ‘dyslexia’. 相似文献

In general, rhetoric and myth play important roles in policymaking. Myths may inspire collective action but may also mystify and blur views on reality. In this article we identify, analyze, and reflect on the myths underlying the e-government programs of Australia, Canada, the United Kingdom, Denmark, and the Netherlands. We found that in all national policies myths of technological inevitability, a new and better government, rational information planning, and empowerment of the intelligent citizen can be discerned. Although the mobilizing powers of these myths are acknowledged, we conclude that existing empirical studies have generated little support for the inescapable telos of these myths, which makes canvas cleaning effects of e-government initiatives less likely. 相似文献

Although the principle of holography was conceived as long ago as 1947, interest was limited until the advent of the laser in 1960 made possible the off-axis holography widely used today. Since then holography has found many applications and become so well known outside the laboratory as to be a recognized art form. Within the last few years considerable progress has also been made in acoustic holography. 相似文献

The purpose of this paper is to compare and contrast characteristics of use and adoption of mobile learning in higher education in developed and developing countries. A comparative case study based on a survey questionnaire was conducted with 189 students (undergraduate and postgraduate) from Makerere University in Uganda and the University of Adelaide in Australia. The Unified Theory of Acceptance and Use of Technology (UTAUT) was employed as the theoretical framework. The results indicated that higher education students in developed and developing countries use a range of technologies for learning, with major differences between Uganda and Australia. The study concludes that mobile learning in higher education in developed and developing country contexts is still at an experimental stage with students using mobile devices in pedagogically limited ways. 相似文献

While long-acting reversible contraception (LARC) reduces risk of repeat-births, use remains low among rural Latinx adolescent mothers. This qualitative study identified perspectives about factors that influence LARC use among this population. Participants were dyads of parenting Latinx adolescent daughters and their mothers (n?=?9 dyads) and nurses (n?=?17). Findings revealed themes specific to this vulnerable population including (a) distinct ways LARC characteristics fit into parenting teenagers’ lives, (b) supportive health care climate toward LARCs, and (c) factors that inhibit LARC uptake. The study has implications for sexuality education that seeks to reduce repeat-births among this population. 相似文献

This paper provides tables of critical values for determining statistically significant discrepancies between Wechsler Verbal/Performance IQ and WIAT subtest and composite scores based on a predicted-achievement method. It is recommended that these tables be used when a statistically significant and diagnostically meaningful Verbal IQ-Performance IQ discrepancy exists rendering either of these IQs a better estimate of a student's ability than the Full Scale IQ. Issues regarding the use of discrepancy formulas in the assessment and diagnosis of learning disabilities are discussed, and basic considerations for using the critical values tables are provided. 相似文献
