James Callaghan's 1976 Ruskin Speech is often presented as denoting the end of consensual policy-making in education and a profigurement of Thatcherite educational policies. This paper considers the validity of visualising 1976 as a foothill of New Right thinking about education and expresses some skepticism about interpretations which neglect subterranean politics.  相似文献

The present study was designed to explore the association between preschool academic skills and Grade 3 achievement among a sample of ethnically diverse children from low-income families. Data were collected from a sample of 1,442 low-income, ethnically diverse children in preschool and associated with Grade 3 achievement in reading and mathematics 4 years later. Mixed-effects modeling indicated that preschool skills significantly predicted Grade 3 achievement measures while controlling for various child-level factors and random school effects. While several preschool factors were predictive of Grade 3 achievement, writing/copying and counting/premathematics skills were consistently strong predictors of Grade 3 achievement across all measures and domains suggesting these are important foundational skills for academic success in midelementary school among low-income, ethnically diverse children. Findings also replicate studies demonstrating that writing plays an important role in learning and achievement. Findings have implications for early education policy and practice intended to support academic development among low-income, ethnically diverse children.  相似文献

This article examines the relationship between shared governance and one school district’s (in)ability to advance educational equity. Specifically, we consider the district’s policies, discourse, and practice around equity within the context of site-based management and shared decision making. We suggest that if equity is indeed a major district responsibility, then it seems inconsistent to leave equity at the mercy of shared governance and occasional externally-imposed mandates because most individual school leaders and educators are not currently taking up this agenda or implementing changes that would result in equitable education. Thus, our work suggests that progress toward educational equity may best be achieved through top-down, directive leadership in districts.  相似文献

Research points to significant numbers of students on college campuses experiencing mental health distress and an ever increasing number of college students who are choosing to make an off-campus educational experience a part of their college careers. When we consider both of these trends together, it is quite apparent that a significant number of students with mental health concerns will spend periods of time studying away from campus, with converging concerns among college mental health and study away professionals about how to best support these students. This article seeks to outline both challenges and opportunities inherent in the collaboration between campus professionals in supporting students with mental health issues before and during their study away experiences.  相似文献

We explore a financial returns dimension of the exploration-exploitation dilemma. Using 1277 R&D announcements by 178 listed bio-pharmaceutical firms, we examine whether investors are myopic along the continuum of exploration (patenting and preclinical trials) to exploitation (human clinical trials and NDA). We find that investors respond positively at every stage, but there are differences between small and large firms. For small firms exploration is favored, provided it is focused. For large firms, there is value in both exploration and exploitation. Projects which are part of an alliance are no more likely to generate abnormal returns. Policy implications are discussed.  相似文献
