This article provides an extended, comprehensive example of how teachers, schools, districts, and external factors (e.g., parental pressure and policy mandates) shape curriculum research in the U.S. It retrospectively examines how three different middle school curriculum units were implemented and scaled‐up in a large, diverse school system. The curriculum materials were cognitively based, hands‐on, guided inquiry units; each focused on a different “big idea” in science. The units met some criteria for instructional strategies rated by the Project 2061 Curriculum Analysis. Using evidence‐based decisions, two of the units were found to be effective and equitable, and went to scale, but one was not effective. However, the course of scale‐up was also affected by a changing policy climate, and proceeded in unpredictable ways, with small scale effects not found at large scale, and experienced teachers less effective than inexperienced teachers. Four years after funding ended, none of the units were sustained within the school district. The interactions between the demands of the units and of the school district's policy environment suggests reasons why this occurred, despite evidence that two of the units were successful with diverse learners. © 2012 Wiley Periodicals, Inc.

Concerns regarding whether a sufficient supply of school psychologists exists have been evident for decades. Studies have predicted that school psychology would face a critical personnel shortage that would peak in 2010, but continue into the foreseeable future. The current study is a 10‐year follow‐up investigation based on previously published personnel shortage projections. Data derived from the National Association of School Psychologists 2009–2010 national study were used to examine current personnel shortages as well as to project the extent to which personnel shortages are likely to continue. Findings indicate that the field of school psychology continues to experience a personnel shortage that will continue through 2025. Additionally, greater rates of retirements are projected for the field for school psychologists who are males, who possess a doctoral degree, and for university faculty. Analyses based on the U.S. Census Regions indicate that notable differences are likely to occur in the match between the supply of and demand for school psychologists based on geographical location. Implications are discussed relating to the recruitment and retention of school psychologists and to the services they deliver.  相似文献

The depictions of cruel witches in Roald Dahl’s novel The Witches echo the cruel, abusive measures taken by adults in the historical treatment of children. The concept of child-hatred, described by Lloyd Demause and other critics, is an effective lens through which to view the hyperbolized hatred of children described in The Witches. However, Dahl’s text deals with more than just the explicit hatred of children. In fact, in its characterization of Grandmamma as an adult that truly values the state of childhood, and in Dahl’s narrative treatment of both his child protagonist and his child audience, Dahl’s text counters the notion that we have progressed to a culture that values and, at times, sacralizes the child. The Witches presents to readers the possibility that child-hatred is not some now-defunct phenomenon, but rather an extant danger in the historical present of childhood, a danger made ever more threatening by its ability to hide under a mask of benevolence. With the many instances of both child-protection and child-hatred that pervade The Witches, the text serves as an apt illustration of the ambivalence inherent in many works of children’s literature, which has been a central concern for scholars of children’s texts for decades.  相似文献

This paper reports on an action research project into the development of a ‘democratic feedback model’ with students on an education studies programme at a post-1992 university in the UK. Building on work that has explored the dialogic dimensions of assessment and feedback, the research explored the potential for more democratic practice in this area. Although much learning and teaching on the programme in question took a collaborative and dialogic approach, assessment and feedback were modelled entirely differently, around the concept of an ‘expert’ marker and ‘novice’ marked. The findings of the research indicate the elements necessary for ‘democratic feedback’, and illustrate the emotional impact of moving from more transmission-based models, grounded in notions of expertise, towards democratic practice. They also highlight the ways in which such work can alert students to the imperfect, messy and human nature of the assessment process. Although the model has limited applicability in its extant form, its constitutive elements might be usefully incorporated within existing practice to promote democratic learning.  相似文献

This article establishes a 2-sided media market in which readers have heterogeneous beliefs, media outlets choose their reporting biases, and advertisement prices are determined by bargaining between media outlets and advertisers. The authors have shown that the presence of advertisers strengthens the reporting bias. The bias is increasing in the advertisers' bargaining power and is generally stronger if the advertisers can advertise in multiple outlets. Finally, the authors present an extension of the model on the formation of joint operating agreements for advertising sales among competing newspapers and show that the media bias will be mitigated.  相似文献

Employees (n=40) at a fast-food restaurant were surveyed about characteristics of their position and their level of satisfaction. Employees were then asked to report with whom they regularly communicated inside and outside the workplace and to indicate how close they were to employees with whom they were linked. Employee turnover was measured after three months had elapsed. A goal of the research was to replicate a model of employee turnover that predicts employees more central in their social network to be less likely to leave, and to test a social support explanation of the centrality model. The results indicated that employees who reported a greater number of out-degree links with friends were less likely to leave. The number of in-degree links with friends did not significantly predict turnover, and neither did network links with peers. Friendship prestige, measured by the number of in-degree links, was strongly correlated with relational closeness and amount of time spent with employees outside the workplace.  相似文献
