This article summarizes the current knowledge of response‐to‐intervention (RTI) models in preschool settings, with an emphasis on evaluating the strengths and weaknesses of our current research base. Particular attention is given to the unique challenges of high‐risk preschool settings. Presently, sufficient empirical support exists to begin establishing tiered intervention systems and building teacher capacity. Lacking, however, are valid and reliable assessment tools and insufficiently trained personnel to support a data‐based decision‐model within high‐risk preschools. We conclude that organizational development should focus on building teacher capacity, establishing high‐quality classroom instruction, and planning for sustainable programs, with adoption of a full RTI service delivery model serving as a long‐range aspirational goal. © 2011 Wiley Periodicals, Inc. 相似文献

Students engaged in problem-based learning (PBL) units solve ill-structured problems in small groups, and then present arguments
in support of their solution. However, middle school students often struggle developing evidence-based arguments (Krajcik
et al., J Learn Sci 7:313–350, 1998). Using a mixed method design, the researchers examined the use of computer-based argumentation scaffolds, called the Connection Log, to help middle school students build evidence-based arguments. Specifically we investigated (a) the impact of computer-based
argumentation scaffolds on middle school students’ construction of evidence-based arguments during a PBL unit, and (b) scaffold
use among members of two small groups purposefully chosen for case studies. Data sources included a test of argument evaluation
ability, persuasive presentation rating scores, informal observations, videotaped class sessions, and retrospective interviews.
Findings included a significant simple main effect on argument evaluation ability among lower-achieving students, and use
of the scaffolds by the small groups to communicate and keep organized. 相似文献

This chapter reviews sensitive periods in human brain development based on the literature on children raised in institutions. Sensitive experiences occur when experiences are uniquely influential for the development of neural circuitry. Because in humans, we make inferences about sensitive periods from evaluations of complex behaviors, we underestimate the occurrence of sensitive periods at the level of neural circuitry. Although we are most interested in complex behaviors, such as IQ or attachment or externalizing problems, many different sensitive periods at the level of circuits probably underlie these complex behaviors. Results from a number of studies suggest that across most, but not all, domains of development, institutional rearing limited to the first 4–6 months of life is associated with no significant increase risk for long‐term adverse effects relative to noninstitutionalized children. Beyond that, evidence for sensitive periods is less compelling, meaning that “the earlier the better” rule for enhanced caregiving is a reasonable conclusion at the current state of the science. 相似文献

Children raised in institutions frequently suffer from a variety of behavioral, emotional, and neuropsychological sequelae, including deficits in attention, executive functions, disorders of attachment, and in some cases a syndrome that mimics autism. The extent and severity of these disorders appear to be mediated, in part, by the age at which the child entered and, in some cases, left the institution. Here we review the neurobiological literature on early institutionalization that may account for the psychological and neurological sequelae discussed in other chapters in this volume. 相似文献

The development of interest in reading and its relationship to reading ability was examined longitudinally in 117 children in Grades 1–3. Interest in reading was measured by eight items from the Elementary Reading Attitude Survey. Less able readers had lower interest in reading, but their development was parallel to that of more able readers. Interest in reading in Grade 1 was weakly correlated with Grade 3 reading ability, but correlations were lower for interest measured in Grades 2 and 3. Hierarchical regression analyses indicated weak and inconsistent effects of reading interest on reading ability after controlling general cognitive ability, SES, phonological awareness and naming speed. It is concluded that interest in reading has only a weak relationship to reading ability in the early elementary years, and that much of that relationship overlaps with the effects of other more powerful predictors. 相似文献

A group randomized controlled trial tested the efficacy of the Friendly Schools program to reduce student bullying behaviour. This socio‐ecological intervention targeted the whole school, classroom, family, and individual students to reduce bullying behaviour. Self‐report data were collected in 29 schools over three years from a cohort of 1968 eight to nine‐year‐olds. Surveys measured frequency of being bullied, bullying others, telling if bullied and observing bullying. Results indicate that intervention students were significantly less likely to observe bullying at 12, 24 and 36 months and be bullied after 12 and 36 months, and significantly more likely to tell if bullied after 12 months than comparison students. No differences were found for self‐reported perpetration of bullying. The findings suggest whole‐of‐school programs that engage students in their different social contexts appear to reduce their experiences of being bullied and increase their likelihood of telling someone if they are bullied. 相似文献

Objective
The primary research objective was to explore the relationship between trajectories of maternal verbal aggression (VA) experienced by low-income, community middle school students across a three-year period and outcomes that have been found to be related to VA in previous work, including a negative view of self and social problems.Method
Longitudinal data were collected from 421 youth (51.8% male) attending two middle schools over 3 years using a multiple-informant survey design. K-means cluster analysis was used to identify trajectories of VA using youth ratings of the Conflict Tactics Scale: Parent-Child (Straus, Hamby, Finkelhor, Moore, & Runyan, 1998). Dependent variables were self-reported depression, self-esteem, delinquency, and peer victimization as well as peer-rated aggression and sensitive-isolated reputation.Results
Four trajectory groups of VA were identified: Low Stable, Increasing, Decreasing, and High Stable. The 3-year average occurrence of VA was: 1.31, 9.18, 10.24, and 31.14 instances, respectively. Gender-specific MANOVAs revealed dramatic differences between the High Stable and Low Stable groups. High Stable boys reported significantly more depressive symptoms, delinquency, peer overt and relational victimization, and were less likely to have a sensitive/isolated reputation than Low Stable boys. High Stable girls reported significantly more depressive symptoms, low self-esteem, delinquency, peer overt and relational victimization and were rated by peers as having more aggressive/disruptive and relationally aggressive reputations than Low Stable girls. Girls in the High Stable group were more likely than other youth to report levels of depressive symptoms and delinquency >1 SD above the mean, while boys in the High Stable group were more likely to report levels of delinquency >1 SD above the mean. The Increasing and Decreasing groups also demonstrated significantly poorer functioning than the Low Stable group on most outcomes. Growth curve analysis revealed that VA showed a contemporaneous association with self-reported delinquency suggesting these factors are closely related.Conclusions
Any level of VA greater than the 1–2 instances per year reported by youth in the Low Stable group was associated with less favorable outcomes. 相似文献969.

This article reports on a two-year ethnographic study of learners participating in multi-site, graduate-level education classes. Classes sometimes met face-to-face in the same physical location; at other times part of the class met physically elsewhere. Yet all were linked through the virtual space. Ethnographic analysis of four data types explored how the instructor and students were able to interact through videoconferencing technologies. Most of the interaction occurred between the local and distance learners by way of cultural guides, local students assigned to host a distance learner through Google Video chat. The distance learners were able to receive real-time attention from the instructor and were able to share differing perspectives that contributed to increased satisfaction in the course. These interactions allowed for a dynamic collaborative effort among a diverse set of actors in the field of education. 相似文献
