Research Findings: The present study examined the degree to which the association between interactive peer play and academic skills was dependent upon the level of classroom quality for a representative sample of culturally and linguistically diverse urban Head Start children (N = 304 children across 53 classrooms). Peer play interactions within the classroom were assessed by teacher assistants in the fall of the year; observations of the quality of classroom instructional, emotional, and organizational support were conducted in the middle of the year; and norm-referenced direct assessments of literacy, language, and mathematics skills were administered in the spring. Findings from multilevel models indicated that disruptive and disconnected peer play behaviors early in the preschool year were associated with lower literacy and language skills regardless of classroom quality. However, interactive peer play early in the year was associated with higher mathematics outcomes when children were enrolled in classrooms characterized by high instructional support. Practice or Policy: Implications for early childhood research, practice, and policy are discussed.  相似文献

Research on pubertal development among Black boys is limited. Addressing this gap, we examined associations between three pubertal domains (e.g., voice change, hair growth, and perceived relative timing), depressive symptoms, self-esteem, and self-efficacy, among a nationally representative sample of 395 African American and 164 Caribbean Black boys (Mage = 15 years). Moderation by ethnic–racial identity (e.g., racial centrality, racial regard) was also explored. Results indicated that for both ethnic subgroups early voice change increased self-esteem; whereas early voice change increased depressive symptoms among boys who felt society views Blacks more negatively. Buffering effects of ethnic–racial identity also varied significantly between the two groups. Findings suggest that the meaning Black boys ascribe to their ethnic–racial group may explain puberty-linked outcomes.  相似文献

The emphasis on competitiveness and the knowledge-based economy in European policymaking has resulted in a heightened focus on monitoring and steering the science system, particularly through metric-based instruments. Policymakers’ general aims of fostering excellent research and breakthroughs are shared by researchers as well; however, below the surface is a paradox that is rarely discussed. The political system and the science system understand and pursue these concepts and objectives differently. Through two case studies on high-performing university-based research environments in Denmark and Sweden, this article uncovers the ways in which highly successful researchers often behave in ways that run counter to policy steering attempts. They do this by shielding themselves and their research group from steering pressures originating in the political system. Using Luhmann’s systems theory, the cases demonstrate why the relationship between the science system and the political system needs to be understood as a horizontal rather than a vertical relationship, and using concepts from organizational theory, provides a model and terminology for identifying and analyzing the types of mechanisms and strategic responses that the science system uses to shield itself from political steering pressures.  相似文献

A six-item survey was sent to state directors of special education (or their equivalent) in all 50 states and the District of Columbia. Items were developed to assess the type and level of prereferral intervention usage reported by state level special education administrators. Despite a lack of empirical support and a relatively inconclusive success rate, many state level administrators reported that they require or recommended the use of prereferral intervention strategies.  相似文献
