The purpose of this study was to investigate the relations among oral and silent reading fluency and reading comprehension for students in Grades 6 to 8 (n = 1,421) and the use of fluency scores to identify middle school students who are at risk for failure on a high-stakes reading test. Results indicated moderate positive relations between measures of fluency and comprehension. Oral reading fluency (ORF) on passages was more strongly related to reading comprehension than ORF on word lists. A group-administered silent reading sentence verification test approximated the classification accuracy of individually administered ORF passages. The correlation between a maze task and comprehension was weaker than has been reported for elementary students. The best predictor of a high-stakes reading comprehension test was the previous year's administration of the grade-appropriate test; fluency and verbal knowledge measures accounted for only small amounts of unique variance beyond that accounted for by the previous year's administration.  相似文献

ABSTRACT

The aim of this study was to prospectively analyse the relationship between workloads and injury in elite football academy players. Elite football academy players (n = 122) from under-19 (U19) and under-21 (U21) of a professional football team competing in UEFA European Cups were followed during 5 seasons. Injuries were collected and absolute workload and workload ratios (4-weeks, 3-weeks, 2-weeks and week-to-week) calculated using a rolling days method with the help of the session Rate of Perceived Exertion. There was no association between absolute workload or workload ratio with the injury incidence in the U19. In the U21, the level of cumulative absolute workloads during 3-weeks (RR = 1.39, p = 0.026) and during 4-weeks (RR = 1.40, p = 0.019) were associated with an increase in injury. There was no association between workload ratio and injury in U21. The significant link between high cumulated 3-weeks and 4 weeks workloads and injury in U21 confirmed the requirement to monitor the internal subjective workload in U21 in order to prevent injury. Further studies exploring the relationships between workload and injury are required in football academy.  相似文献

OBJECTIVE: This study examined whether children who received child welfare services (e.g., in-home or out-of-home placement) were more or less likely to become incarcerated as serious and violent youthful offenders than those children who were investigated as victims of abuse and neglect but received no further child welfare intervention. METHOD: Administrative data on child abuse reporting, foster care, birth records, and juvenile corrections (CYA) were linked to prospectively examine the risk of incarceration as an adolescent following an investigation of abuse or neglect after age 6. The 10 county California sample included 159,549 school-aged children reported for abuse and neglect after 1990. RESULTS: About 8 per 1,000 children in the sample were later incarcerated in CYA. African American and Hispanic children who received in-home or foster care services after the index investigation event had a lower risk of incarceration than those whose cases were closed after the investigation. Among females, the rate of incarceration was highest for those who experienced foster or group care placements. Children initially reported for neglect were more likely to be incarcerated than those reported for physical or sexual abuse. CONCLUSIONS: Public child welfare services have rarely been assessed in terms of future negative child outcomes. This study finds that one serious negative outcome, CYA involvement, can only be understood when a number of factors are considered. The importance of understanding the differences between how different subpopulations respond to services is highlighted. Specifically, our findings suggest that more attention should be focused on children who are now receiving no services after an investigated child abuse and neglect report, on females, and on victims of child neglect.  相似文献

This article investigates changes in gender differences evident in the performance of grade 8th grade students participating in the Trends in International Mathematics and Science Study (TIMSS) between 1995 and 2003. Gender specific results and patterns found in TIMSS 1995 were compared with later cycles of the study in order to address the question of how far the mathematics and science gender gap has narrowed over time. Using a regression approach to compare the trend data, the findings indicated no major changes for mathematics but it appears that the gap in science may be closing, especially in the previously male dominated content areas of chemistry and physics.  相似文献

Objective: Infants comprise nearly one fourth of all entries to foster care. Linkage of administrative birth and placement data can provide information about these infants that may otherwise be unavailable or difficult to obtain.Method: Statewide birth records and foster care placement histories were linked via probability matching. Logit regression was used to compare 26,460 maltreated infants who entered foster care between 1989 and 1994 with a random sample of 68,401 other infants born during that time frame.Results: Infants in care were more than twice as likely to have single parents and be born with low birthweight, and twice as likely to have been born with a birth abnormality as other infants, controlling for other factors. The largest difference was in the eightfold increased likelihood for mothers of infants in care to have had no prenatal care. Infants in care were nearly three times as likely to be born into larger families (third or greater live births to the mother). Mothers of infants in care were more than twice as likely to be African American compared to White than mothers of other infants, while Hispanic and Other ethnic groups were underrepresented in the group of infants in care. Foreign born mothers, especially Hispanic women, were much less likely to have infants in care than they were to have children in the other group.Conclusions: Administrative datasets, while often limited in the number of variables they include and scope of their information, can be a valuable tool when used to understand demographics and frame questions for future research. Infants who enter foster care differ in substantial ways from other children. These findings have important implications for future research aimed toward targeting of child welfare services and supports.  相似文献

A randomized controlled trial was conducted to determine the efficacy of U-Pace instruction for older undergraduates, ages 25 and older, and younger undergraduates, ages 18 to 24. Additionally, change in learner perceptions across the semester, an outcome not reported in the literature on U-Pace instruction, was investigated. In both younger and older undergraduates U-Pace instruction produced greater learning, greater academic success, and sustained or improved students’ perceptions of themselves as learners compared with Face-to-Face instruction. The findings provide strong support for the efficacy of U-Pace instruction in younger and older students and highlight a possible mechanism underlying U-Pace instruction’s effects on learning and academic success.  相似文献

This study compared the effects on reading outcomes of delivering supplemental, small-group intervention to first-grade students at risk for reading difficulties randomly assigned to one of three different treatment schedules: extended (4 sessions per week, 16 weeks; n = 66), concentrated (4 sessions per week, 8 weeks; n = 64), or distributed (2 sessions per week, 16 weeks; n = 62) schedules. All at-risk readers, identified through screening followed by 8 weeks of oral reading fluency (ORF) progress monitoring, received the same Tier 2 reading intervention in groups of 2 to 4 beginning in January of Grade 1. Group means were higher in word reading and ORF at the final time point relative to pretest; however, the groups did not differ significantly on any reading outcome or on rates of adequate intervention response. Of potential covariates, site, age, free lunch status, program coverage rate, and tutor were significantly related to student outcomes; however, the addition of these variables in multivariate models did not substantially change results. Rates of adequate intervention response were lower than have been reported for some first-grade interventions of longer duration.  相似文献
