Executive functions (EF), including working memory, inhibition, and cognitive flexibility, vary as a function of socioeconomic status (SES), with children from economically disadvantaged backgrounds having poorer performance than their higher SES peers. Using observational methods, we investigated cognitive stimulation in the home as a mechanism linking SES with EF. In a sample of 101 children aged 60–75 months, cognitive stimulation fully mediated SES-related differences in EF. Critically, cognitive stimulation was positively associated with the development of inhibition and cognitive flexibility across an 18-month follow-up period. Furthermore, EF at T1 explained SES-related differences in academic achievement at T2. Early cognitive stimulation—a modifiable factor—may be a desirable target for interventions designed to ameliorate SES-related differences in cognitive development and academic achievement.  相似文献

Although college readiness is a centerpiece of major educational initiatives such as the Common Core State Standards, few systems have been implemented to track children's progress toward this goal. Instead, college‐readiness information is typically conveyed late in a student's high‐school career, and tends to focus solely on academic accomplishments—grades and admissions test scores. Late‐stage feedback can be problematic for students who need to correct course, so the purpose of this research is to develop a system for communicating more comprehensive college‐readiness diagnoses earlier in a child's K‐12 career. This article introduces college‐readiness indicators for middle‐school students, drawing on the National Education Longitudinal Study of 1988 (NELS), a nationally representative longitudinal survey of educational inputs, contexts, and outcomes. A diversity of middle‐school variables was synthesized into six factors: achievement, behavior, motivation, social engagement, family circumstances, and school characteristics. Middle‐school factors explain 69% of the variance in college readiness, and results suggest a variety of factors beyond academic achievement—most notably motivation and behavior—contribute substantially to preparedness for postsecondary study. The article concludes with limitations and future directions, including the development of college‐readiness categories to support straightforward communication of middle‐school indicators to parents, teachers, and students.  相似文献

In this study, we focused on increasing the reliability of ability-achievement difference scores using the Kaufman Assessment Battery for Children (KABC) as an example. Ability-achievement difference scores are often used as indicators of learning disabilities, but when they are derived from traditional equally weighted ability and achievement scores, they have suboptimal psychometric properties because of the high correlations between the scores. As an alternative to equally weighted difference scores, we examined an orthogonal reliable component analysis, (RCA) solution and an oblique principal component analysis (PCA) solution for the standardization sample of the KABC (among 5- to 12-year-olds). The components were easily identifiable as the simultaneous processing, sequential processing, and achievement constructs assessed by the KABC. As judged via the score intercorrelations, all three types of scores had adequate convergent validity, while the orthogonal RCA scores had superior discriminant validity, followed by the oblique PCA scores. Differences between the orthogonal RCA scores were more reliable than differences between the oblique PCA scores, which were in turn more reliable than differences between the traditional equally weighted scores. The increased reliability with which the KABC differences are assessed with the orthogonal RCA method has important practical implications, including narrower confidence intervals around difference scores used in individual administrations of the KABC.  相似文献

Engaging in relationships with other organizations is one way for nonprofit community sport organizations (CSOs) to acquire needed resources, knowledge, and other social benefits while achieving important public purposes and building community cohesion. This study explored the processes and outcomes of interorganizational relationships in CSOs through semi-structured interviews with presidents of these organizations (N = 20). The findings revealed key relationship processes including trust, consistency, balance, and engagement as well as specific management skills. The findings also revealed that relationships impacted CSOs through enabling improvements to program/service quality and operations, and enhancing community presence. The study contributes to the interorganizational relationship literature and our understanding of how relationships advance organizational goals in this small nonprofit context.  相似文献

Collection and research activities in biology at the New York State Museum (NYSM) are centered in the Biological Survey. Its operating funds are set by the governor, the state legislature, and the state education department. Additional funding is provided from grants and the New York State Museum Institute. Operating budgets and staff size between 1973 and 1994 were rather constant or rose somewhat during the first three-fourths of this period, then increased dramatically as a result of special appropriations by the legislature. In recent fiscal years, there were major cuts in the NYSM's operating budget, and the Biological and Geological Surveys were especially targeted for “downsizing.” The museum embarked on a campaign to have the proposed cuts more broadly assigned or the funding restored. The methods used included testimonials to legislators by survey clients and visits by museum staff to explain the benefits of the surveys. The Museum Visiting Committee and the Business and Industry Advisory Council were formed to further ensure support of the surveys. This advocacy emphasized the importance of a clear focus on actual and potential client needs in research and other programs of the surveys, constantly advertising what we do, and broadly-based collaborative projects that make good use of expertise existing in the state. The Biodiversity Research Institute (BRI) was created by legislation in 1993 and placed within the NYSM.  相似文献
