This paper is about middle schools and the effects of recent policies on the curricula organisation of six of them. We begin by establishing some general links between middle school origins, brief history and development, and wider economic and political forces for change. Drawing on four years of research with a group of schools in one local authority, we describe some of the directions of change which followed the Great Debate. We highlight recent changes as these schools came under increasing bureaucratic control, with the emphasis on the organisation of pupil selection and changes from mixed ability grouping, to setting, and back to mixed ability groups. We conclude with some theoretical discussion related to the work of Habermas. 相似文献

In 1997, the New York School Choice Scholarships Foundation Program (SCSF) randomly offered three-year scholarships to attend private schools to approximately 1,000 low-income families in New York City. In this paper we leverage exogenous variation generated by the SCSF to estimate the causal effect of the private school voucher offer—and the private school attendance it induced—on later-life voter registration and turnout outcomes. Our results demonstrate that the voucher intervention had no effect on registering to vote or voting in any of several elections for either the full sample or any of several demographic subgroups. Although unique aspects of the SCSF context impose limits on the scope of our results, they have clear implications for assessing the relative effectiveness of public and private schools in preparing democratic citizens. We close the paper by discussing the implications of the results for research and policy. 相似文献

OBJECTIVE: To examine family risk factors associated with dissociative symptoms among homeless and runaway youth. METHOD: Three hundred and twenty-eight homeless and runaway youth were interviewed using a systematic sampling strategy in metropolitan Seattle. Homeless young people were interviewed on the streets and in shelters by outreach workers in youth service agencies. RESULTS: The current study revealed widespread prevalence of dissociative symptoms among these young people. Multivariate analyses revealed that sexual abuse, physical abuse, and family mental health problems were all positively associated with dissociative symptoms. No gender differences were found for any of the models. CONCLUSIONS: Dissociative behavior is widespread among these youth and may pose a serious mental health concern. Some young people experience numerous stressors, and with few resources and little support available, many may invoke maladaptive strategies such as dissociative behavior to handle such situations, which may in turn be detrimental to their mental health. Unless youth are provided with programs and intervention, the cycle of abuse that they have experienced at home is likely to continue on the street. 相似文献

This research examined the relation between individual differences in inhibitory control (IC; a central component of executive functioning) and theory-of-mind (ToM) performance in preschool-age children. Across two sessions, 3- and 4-year-old children (N = 107) were given multitask batteries measuring IC and ToM. Inhibitory control was strongly related to ToM, r = .66, p < .001. This relation remained significant controlling for age, gender, verbal ability, motor sequencing, family size, and performance on pretend-action and mental state control tasks. Inhibitory tasks requiring a novel response in the face of a conflicting prepotent response (Conflict scale) and those requiring the delay of a prepotent response (Delay scale) were significantly related to ToM. The Conflict scale, however, significantly predicted ToM performance over and above the Delay scale and control measures, whereas the Delay scale was not significant in a corresponding analysis. These findings suggest that IC may be a crucial enabling factor for ToM development, possibly affecting both the emergence and expression of mental state knowledge. The implications of the findings for a variety of executive accounts of ToM are discussed. 相似文献
