Individuals in eight different types of administrative positions in two‐year colleges were asked to rate the importance of a variety of external and internal issues in the next five years. The purpose of the study reported here was first to identify those internal and external issues that administrators viewed as being of high importance. A second purpose was to assess the degree of consensus among differing types of administrative positions. The third objective was to identify differences between public and independent two‐year college, between men and women, and minority and white administrators perceptions of issues identified as being most important. There was a high degree of agreement across administrative groups as to the importance of five external issues; and when asked to indicate the two most critical issues, administrators were almost unanimous in their assessment. There is less agreement on the two critical internal issues. Some differences by gender and racial/ethnic group were noted, but the differences were not as great as might have been expected.  相似文献

Previous research has established that student learning is influenced by how accurately teachers perceive student academic ability. But studies rarely investigate the degree to which inaccuracies in teacher perceptions exacerbate demographic inequality in academic ability. Using a sample of almost 14,000 children from the Early Childhood Longitudinal Study, Kindergarten Cohort, we found that children whose literacy skills are overestimated by their teachers typically gain more literacy skills during kindergarten. Conversely, children whose skills are underestimated learn less. It is important to note that the skills of socioeconomically disadvantaged children are on average underestimated. As a result, inequalities in kindergarten literacy development stem in part from the links between teacher misperceptions and student background. We also explored the extent to which these relationships operate through practices associated with ability grouping. We found instructional grouping to be a weak facilitator of the link between teacher perceptions and student learning, suggesting the need for further research that identifies the social and structural classroom characteristics that link teacher perceptual accuracy to student learning.  相似文献

Research Findings: As policymakers expand access to preschool, the sociodemographic composition of preschool classrooms will become increasingly important. These efforts may create programs that increase the concentration of children from low-income families or, alternatively, foster the creation of socioeconomically diverse preschool classrooms. What effect the creation of such contexts would have on very young children remains unclear. Using multilevel methods and data on 2,966 children in 704 prekindergarten classrooms, this study explores the relationship between socioeconomic classroom composition and children's social and cognitive development. The results indicate positive associations between the mean socioeconomic status (SES) of the class and children's receptive language, expressive language, and mathematics learning, regardless of children's own sociodemographic backgrounds and the characteristics of their classrooms. However, the analyses indicate no association between the development of social competence and class mean SES. Practice or Policy: The links between classroom SES and language and mathematics development were comparable in size to those associated with instructional quality and even children's own SES. Neither structural nor instructional characteristics of prekindergarten classrooms explained these relationships, suggesting the possibility of direct peer effects. The findings indicate that the composition of children's classrooms should be considered an important aspect of preschool quality.  相似文献

Chronic disruptive behaviors during early childhood are associated with many poor developmental outcomes including, but not limited to, school dropout and conduct disorder during adolescence. Much is known regarding effective intervention procedures for disruptive classroom behaviors by preschool children. Unfortunately, evidence-based intervention procedures may not be implemented with integrity in applied settings. Direct behavioral consultation may increase teacher intervention integrity because of direct training procedures used with teachers and students during routine classroom activities. This study evaluated a nondisruptive direct training method for increasing Head Start teachers' use of praise and effective instruction delivery. Results indicated that the direct training procedure implemented during routine instructional activities resulted in increased use of praise and effective instruction delivery that maintained following training. Additionally, increased use of praise and effective instruction delivery resulted in reductions in children's disruptive classroom behavior.  相似文献

Consultation is a promising approach to creating change in early childhood programs, from innovations in instructional strategies to the enhancement of global program quality. Studies of consultation effectiveness have been hampered by limited reports of implementation fidelity related to consultation procedures. This article describes the challenges of supporting and measuring implementation fidelity in a 5-state study in which community consultants followed a collaborative consultation model to enhance global quality in childcare programs. The authors consider the limitations of using a randomized experimental design to study the effectiveness of consultation and share lessons learned in their efforts to enhance treatment fidelity without compromising the basic tenets of the model or the rigorous design.  相似文献

Theorists of discourse have long recognised the complexities of attributing reported speech in textual circulation. Yet rarely does one follow words from an original speech event through their many re-entextualisations, and it has proved particularly difficult to capture such circulations between oral events, print, and online media. This article captures such movements by following the mediatised – and politicised – afterlife of a speech event that would normally be classified, in academia, as ‘a talk’. It begins with a talk on Russia, given by the author-anthropologist of this paper, that was (mis)reported in Russian by a Voice of America (VOA) journalist, then traces the resulting text's subsequent movement from the VOA website into the Russian fieldsite that the oral talk described. It explores how the tone and substance of debates over politics and representation were enabled, constrained, and otherwise shaped by the particular textual circulations made possible in digital media. As the text traversed online newspapers, comments forums, blogs, social media networks, and private-turned-public personal emails, it produced a body of commentary that was both directly and indirectly a struggle over representation. While substantive debates unfolded over ethnic and national politics, much of the online commentary concerned the expertise of the commenters weighing in and the expertise and identity of the anthropologist who had been cited. This essay argues that Russian commenters and posters were productively using the intertextual gaps offered by digital circulation, while minimising those gaps' increasing breadth and depth by attributing ‘original’ authorship to a discrete, stable person.  相似文献

This paper focuses on the effect that diversity has on the performance and satisfaction of student groups in a computer simulation project. Using structural equation modeling, we find evidence to support the contention of previous research that diversity negatively affects group satisfaction. This finding was strongest for undergraduate groups. While the relationship between diversity and performance is inconclusive, groups that are dominated by one person tend to have below average performance.  相似文献
