For the past 35 years, Title I of the Elementary and Secondary Education Act has been the largest and most important federal resource for reforming high-poverty schools. Drawing on recent research, this article documents what we know about Title I's overall effectiveness and discusses how it may become a more effective intervention. The author concludes by making 3 policy recommendations for fostering better research and better programs: implement a rigorous and uniform national accountability system; support continued research and development of replicable programs and methods for improving schooling for disadvantaged children; and encourage large-scale randomized experiments of promising programs and practices.  相似文献

In this article, we report kindergarten student and teacher outcomes from a quasi-experimental evaluation of The Superkids, a systematic, phonics-based, comprehensive K-2 reading program. We recruited 23 kindergarten teachers to implement The Superkids program from a diverse, yet predominantly ethnic minority, group of classrooms from across the United States. We then employed a precise computerized matching methodology to derive a statistically equivalent comparison group of 20 control teachers who implemented their standard “business as usual” core literacy program. Multilevel analyses of classroom-level effects of The Superkids revealed achievement advantages of more than 1/10 of a standard deviation, d = 0.11, to 1/4 of a standard deviation, d = 0.25, for the treatment group on the 5 subtests from the Stanford Achievement Test, 10th edition (SAT-10). Four measures of teachers’ self-reported satisfaction with the core reading program used in their classrooms also revealed statistically significant advantages for Superkids of nearly three-quarters of a standard deviation, d = 0.72, to nearly 1½ standard deviation units, d = 1.49.  相似文献

As part of a newly created library marketing plan, librarians at the College of Wooster undertook a study of the communication preferences of students, faculty, and staff in early 2015. The results of the survey helped to develop a comprehensive picture of what library resources and services these constituencies are interested in learning about, as well as when, where, and how they prefer to learn about them. This article describes the development, distribution, results, and analysis of the survey, and highlights the importance of campus-specific library marketing practices.  相似文献

In Experiment 1, rats were trained to leverpress on a variable ratio (VR) 30 schedule with a 500-msec delay between the reinforced response and food delivery. Subjects that experienced a signal during the delay responded faster than did control subjects that received the stimulus un-correlated with reinforcement. Higher response rates were obtained when the stimulus used to signal reinforcement was auditory rather than visual. Experiments 2 and 3 compared the effects of signaling reinforcement with either a localized or a diffuse light on responding maintained by VR schedules of reinforcement. Elevated response rates were observed with the diffuse stimulus, but the localized stimulus failed to produce such potentiation. Experiment 3 also examined the conditioned reinforcing power of localized and diffuse visual stimuli. These results are discussed with reference to (1) theories of selective association and sign tracking and (2) their implications for current theories of signaling reinforcement.  相似文献

Residual categories are those which cannot be formally represented within a given classification system. We examine the forms that residuality takes within our information systems today, and explore some silences which form around those inhabiting particular residual categories. We argue that there is significant ethical and political work to be done in exploring residuality.  相似文献

Researchers have reported that student authoritarianism, dogmatism, intelligence, convergent-divergent abilities, conceptual level, anxiety, compulsivity, achievement motivation, achievement orientation, locus of control, independence-dependence, and extraversion-introversion interact with teacher directiveness in relation to grades and satisfaction. Evidence that the student variables are moderately intercorrelated suggested that some of the interactions may not be independent. The present study was initiated to simplify the multivariate nature of these interactive patterns by carrying out a modified stepwise regression analysis of the twelve interactions which could result in a lesser number of nonredundant interactions emerging, weighted according to how much unique variance they could account for in grades and satisfaction. Data were collected from 445 students in the classes of 26 Grade 11 and 12 English teachers at five schools in regard to English grades, satisfaction with the teacher and the course, the 12 student variables, and perceived teacher directiveness. Only achievement motivation produced significant interactions. Consequently, the planned regression models could not be constructed.  相似文献
