Perched on the Mason-Dixon line, Baltimore ignored calls for resistance from its southern neighbors by becoming one of the first cities in the country to comply withBrown. By the beginning of the 1955 school year, leaders had implemented a desegregation plan, and Baltimore was being applauded for the early and peaceful integration of its public schools. Within a few years, however, the praise faded as it became clear that Baltimore still suffered from de facto segregation. Faced with this reality, the school board refused to take the steps necessary to remedy the problem, instead shifting the blame to society at large. This failure by the board started a pattern of abandonment by school leadership that culminated in 1991 with the privatization of several of Baltimore's public schools. The result of this abandonment is a crippled school system that still has not dealt with issues of race and equality.  相似文献

Based on the Job Demands-resources (RD-R) model, the aim of the current study was to examine how pressure arising from imposed curriculum changes and teacher self-efficacy relate to perceived stress in teachers. Participants (839 teachers working in English schools) completed an online survey that contained questions about demographics, self-reported pressure from imposed curriculum changes, teacher self-efficacy, and perceived stress. Pressure from imposed curriculum changes was positively, and teacher self-efficacy negatively, related to perceived stress. Teacher-self efficacy moderated relations between pressure from imposed curriculum changes and perceived stress. High teacher self-efficacy was associated with lower perceived stress, relative to low teacher self-efficacy, when pressure from imposed curriculum changes was low. The differential advantage offered by high self-efficacy declined as pressure from imposed curriculum changes increased.  相似文献

This study examines sources of influence over 290 faculty members of a large public university. The role expectations a faculty member has for himself and the role expectations of the employing organization both predict positively and significantly the role behaviors of the respondents. The departmental colleagues' expectations predict significantly role behaviors for the research role only. In addition, the degree of person—role conflict a faculty member is exposed to is related to his productivity (research) but not to his satisfaction. The implications of the results are explored for both role theory and for the understanding of faculty behavior.  相似文献

Special services usage and related assessment procedures were investigated for 50 students with epilepsy. Fifty‐six percent of students with epilepsy received special education services, with mental retardation designation and self‐contained placement common, especially among individuals with epilepsy plus a coexisting neurological diagnosis. Sixteen percent of participants had an “other health impairment” designation, and several of these were deemed eligible in at least one other special education category. The majority of students who had been evaluated were administered IQ, adaptive behavior, speech/language, and sensorimotor components, whereas few were assessed for executive or memory functions. Little information about antiepileptic drugs, their effects, or the actual manifestation of students' seizures appeared in special services school documents. Additional empirical information regarding services for children with chronic health conditions, such as epilepsy, is necessary to improve school psychologists' practice. © 2006 Wiley Periodicals, Inc.

This study examines the claim that attempting, or guessing at, more items yields improved formula scores. Two samples of students who had taken a form of the SA T- Verbal consisting of three parallel half-hour sections, were used to form the following scores on each of the three sections: the number of attempts, a guessing index, the formula score, and (indirectly) an approximation to an ability score. Correlations were obtained separately for the two samples between the attempts, and the guessing index, on one section, the formula score on a second section, and ability as measured by the third section. The partial correlations obtained hovered near zero, suggesting, contrary to conventional opinion, that, on average, attempting more items and guessing are not helpful in yielding higher formula scores, and that, therefore, formula scoring is not generally disadvantageous to the student who is less willing to guess and attempt an item that he or she is not sure of. On closer examination, however, it became clear that the advantages of guessing depend, at least in part, on the ability of the examinee. Although the relationship is generally quite weak, it is apparently the case that more able examinees do tend to profit somewhat from guessing, and would therefore be disadvantaged by their reluctance to guess. On the other hand, less able examinees may lower their scores i f they guess.  相似文献

The Times Higher Education Supplement was the first newspaper to publish an international ranking of universities in November 2004 Jobbins, D. 2002. The Times/The Times Higher Education Supplement – League Tables in Britain: An Insider's View”. Higher Education in Europe, 27(4): 383389. [Taylor & Francis Online] [Google Scholar]. This article describes the evolution of the international rankings from their origin in a limited peer review exercise through the gradual refinement of a national ranking based on, as far as possible, publicly available, verifiable, and accepted data. The author describes the methodology of the international ranking and presents the case for the integrity of commercially produced rankings, national and international, which can be as objective, robust, and transparent as initiatives from within the university community itself.  相似文献

Multidimensional sealing and related analytic procedures were used to estimate the accuracy of a set of goals used to pattern the design of a graduate curriculum. The analysis suggests that this goal set faithfully represents the essential elements within the area of professional practice to be taught. The procedures described have utility for a wide range of goal-focused analyses.  相似文献
