This paper uses one national case to illustrate how diverse ideological agendas of central state agencies contest the discursive space within which major education policy reforms are developed. In Aotearoa New Zealand in 1988, ‘self‐managed’ schools were promoted ostensibly to allow parents more say in their children’s education and local school administration. The Tomorrow’s Schools reform policy texts included an existing social democratic partnership rhetoric, positioning principals as professional leaders working collaboratively with elected parent boards of trustees. However, the new ideology of ‘parental choice’ of school within a local schooling marketplace, underpinned by a chief executive or market managerial model of principalship, was later operationalised through mechanisms of ‘steerage’ from the centre. To explain this shift, we examine selected policy text pre‐cursors to the reforms and identify how contrasting forms of ‘principal’ and ‘teacher’ identity emerged within social democratic, neo‐liberal and market managerial ideologies. We further show that while radical (Treasury) market liberal arguments for labour market deregulation and consumer choice failed to gain widespread support, the State Services Commission preferred market managerialist strategies for promoting public accountability of schools (based on aggregate student achievement outcome data and centrally determined national educational priorities) were successfully embedded during the 1990s.  相似文献

Objectives

A commonly cited risk factor for sexually intrusive behavior (SIB) among children and adolescents is a history of abuse. Based on a large and non-clinical nationwide sample of children who were investigated as abuse victims and suspects of SIBs in Israel over a decade, the present study examines the rate of abuse history among child suspects who have admitted SIBs. In addition, this study compares some personal and family characteristics as well as selected aspects of SIBs reported by children with and without a history of abuse. Abuse history is then used to predict the nature of SIBs after controlling for other predictors.

Methods

National data files of the investigation of alleged child victims and child suspects aged 14 or under were electronically merged, allowing the identification of a sub-group of suspects, out of all suspects, who had a record of child abuse. Using only confirmed cases of boys with SIBs, child suspects with a record of abuse were compared to the larger group of child suspects with no record of abuse.

Results

Of 3,554 child suspects of SIBs, 345 or 9.7% had a formal record of abuse. Boys with a record of abuse engaged in SIBs at a younger age; were more likely to display mental disabilities; more often belonged to large size, single-parent, low SES, and immigrant families and were more likely to be removed from home to alternative care than boys with no record of abuse. The nature of SIBs varied across the groups, with victim-suspects more likely than their counterparts to act repeatedly, and to do so alone rather than in the presence of others. Victim-suspects were more likely to involve in SIBs with younger children, with siblings, and with unrelated children. Most aspects of SIBs were predicted by abuse history after controlling for other predictors, with some differences between age groups being evident.

Conclusions

Although abuse history is uncommon among children displaying SIBs in this sample, it seems to affect the involvement of children at a younger age in more severe SIBs, posing a higher risk to other children.

Practical implications

The low rate of abuse history among boys with SIBs suggests that clinical assessors of SIBs in children should not assume that these children have been victims of abuse or that abuse is a necessary component in the development of SIBs. This implies that the exploration of past abuse in the assessment of children with SIBs is not always relevant and that trauma-related components in the treatment of these children should be selective. As past-abuse is less related to SIB's for older children, the clinical focus on abuse is even less relevant for older children. However, when boys with SIBs have been past-victims, they seem to be in greater need for treatment than other boys with SIBs. Moreover, the dynamics of SIBs by past victims should raise more concern for older than for younger children.  相似文献

This paper focuses on the perspectives of Years 7 and 8 Pasifika students on mathematics learning, in particular their views about the communication of solution strategies with others (their peers), and their teacher. Pasifika students' ideas about the importance of communicating their mathematical reasoning and strategies to peers and teachers were analysed and themes identified. While most students were in agreement about the importance of explaining their thinking to others, there was considerable variation in the reasons they gave for their views. The findings are interpreted in relation to socio-cultural theory and recent writing about requirements for citizenship in the twenty-first century.  相似文献

Objective

Psychological maltreatment (PM) is the most prevalent form of child abuse, and is the core component of most of what is considered as child maltreatment. The aim of this work was to explore differential adverse outcomes of the different types of PM in the mental health and functioning of children living in homes in which they are exposed to intimate partner violence (IPV).

Method

Participants were 168 children, aged between 4 and 17, whose mothers experienced IPV. They were assessed using different measures of psychopathology and functioning: Diagnostic Interview for Children and Adolescents-IV, Child Behavior Checklists and Child and Adolescent Functioning Assessment Scale. Furthermore, IPV was assessed with the Schedule for Assessment of Intimate Partner Violence Exposure in Children and the Index of Spouse Abuse. Statistical analyses were carried out with regression models adjusted by means of Generalized Estimating Equations.

Results

Spurning was the PM subtype with the greatest global effect on the children, as it was significantly associated with internalizing and externalizing problems. Denying emotional responsiveness specifically increased the risk of internalizing psychopathology and impairment in the emotional area. Terrorizing was not significantly associated with a greater number of negative outcomes in children's psychopathology or functioning in this population.

Implications

The results suggest the importance of taking PM types into account in order to fully understand the problems of children exposed to IPV at home, and for the design of effective treatment and prevention programs.  相似文献

The present study explores Greek parents’ views on parental educational involvement and its impact on adolescent scholastic and social development. Specifically, aspects of parental involvement such as the achieved objectives of current parent–school communication, the psychological climate dominating teacher–parent interactions and parents’ suggestions for improvement of current policies and practices are examined. Four hundred and seventy‐five parents participated in the study. Findings showed that family–school communication is believed to be insufficient in Greece, despite the fact that parents tend to: (1) regard their cooperation with teachers as determinative of adolescent academic and psychosocial development; (2) consider teachers to be friendly and caring; and (3) believe that secondary school provides some opportunities for constructive parental involvement. These paradoxes are discussed and explained as a result of radical changes in current social and educational values, principles and objectives.  相似文献

This paper explores the development of children’s centres in England between 2004 and 2008, focusing on the newly created centres that have been located on primary and nursery school sites. Using both an analysis of policy documents and interview data from three urban local authorities, we examine the use of premises and the differing priorities of centre staff and school heads, particularly in relation to the balance of services between early years education, childcare and family support. We also explore governance issues, focusing especially on patterns of accountability. In so doing, we also examine the tensions that exist between children’s centres located on primary and on nursery school sites and the schools themselves.  相似文献

This article draws on ethnographic fieldwork that took place in 2004 in a boys’ hifz class which met in a north‐east London mosque. Drawing on the results of semi‐participant observations and semi‐structured interviews, the research findings are collated under five themes: the routines and rhythms of the hifz class; routes into the hifz class; the students’ perceptions of what they were doing; the ‘sacrifice’ of becoming a hafiz; and hifz class and the rest of students’ lives. Though the analysis is largely of the subjective responses of hifz class members and cannot therefore give definitive answers to research questions, the author points to some of the implications of this work and offers pointers for further research work in this field.  相似文献
