Based on theoretically driven models, the Chicago School Readiness Project (CSRP) targeted low-income children's school readiness through the mediating mechanism of self-regulation. The CSRP is a multicomponent, cluster-randomized efficacy trial implemented in 35 Head Start-funded classrooms (N = 602 children). The analyses confirm that the CSRP improved low-income children's self-regulation skills (as indexed by attention/impulse control and executive function) from fall to spring of the Head Start year. Analyses also suggest significant benefits of CSRP for children's preacademic skills, as measured by vocabulary, letter-naming, and math skills. Partial support was found for improvement in children's self-regulation as a hypothesized mediator for children's gains in academic readiness. Implications for programs and policies that support young children's behavioral health and academic success are discussed.  相似文献

With a sample of African American and European American 3rd- and 4th-grade children (N = 486, ages 8-11 years), this study examined classroom ethnic composition, peer social status (i.e., social preference and perceived popularity as nominated by same- and cross-ethnicity peers), and patterns of ethnic segregation (i.e., friendship, peer group, and cross-ethnicity dislike). African American--but not European American--children had more segregated relationships and were more disliked by cross-ethnicity peers when they had fewer same-ethnicity classmates. African American children's segregation was positively associated with same-ethnicity social preference and perceived popularity and with cross-ethnicity perceived popularity. European American children's segregation was positively associated with same-ethnicity social preference but negatively associated with cross-ethnicity social preference and perceived popularity.  相似文献

The purpose of this study was to develop a poststructural feminist pedagogical model and to investigate whether vocational-and-technical college students receiving poststructural feminist instruction would exhibit better learning achievement and critical thinking ability, and express greater satisfaction with their classes than those receiving traditional instruction. In applying a poststructural feminist model, the researchers intended to help both the teacher and students work together to overcome the estrangement and alienation that have long been the norm in the contemporary Chinese education system. The research results show that the poststructural feminist pedagogy had a positive effect upon the participants in the experimental group. Several conclusions are elicited from the study. First, in the English language achievement post-test, the participants receiving the poststructural feminist instruction significantly outperformed those receiving the traditional banking instruction in terms of listening, vocabulary, grammar, and reading. Second, in the critical thinking ability post-test, the participants significantly outperformed those receiving the traditional banking instruction in terms of length, focus, content, organization, and style. Third, in regard to the students’ satisfaction, it was clearly shown that the students who received the instruction informed by poststructural feminist pedagogy expressed significantly greater satisfaction than those who had received traditional banking instruction in terms of instructional objective, teaching method/materials, teacher quality, class environment, and assessment.  相似文献

In this article, Walter Parker brings structure and agency to the foreground of the current tumult of public schooling in the United States. He focuses on three structures that are serving as rules and resources for creative agency. These are a discourse of derision about failing schools, a broad mobilization of multiculturalism, and an enduring nationalism. Drawing on Anthony Giddens's structuration theory, Parker examines how these discourses figure in redefining school reform, redefining school curricula, and requiring schools once again to serve nationalistic purposes.  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 study reports on several specific neurocognitive process predictors of reading outcomes for a sample of 278 children with reading disabilities. Three categories of response (i.e., poor, average, and good) were formed via growth curve models of six reading outcomes. Two nested discriminant function analyses were conducted to evaluate the predictive capability of the following models: (a) an intervention and phonological processing model that included intervention group, phonological awareness, and rapid naming and (b) an additive cognitive neuropsychological model that included measures of memory, visual processes, and cognitive or intellectual functioning. Over and above the substantial explanatory power of the base model, the additive model improved classification of poor and good responders. Several of the cognitive and neuropsychological variables predicted degree of reading outcomes, even after controlling for type of intervention, phonological awareness, and rapid naming.  相似文献

This chapter first presents a review of research on the development of adopted children, focusing on meta‐analytic evidence and highlighting comparisons between adopted children with and without histories of early adversity. Some methodological issues arising from this literature are considered as well. Second, 7 longitudinal studies of adopted children's development are described, and the convergence of findings across the longitudinal studies and with the cross‐sectionally based meta‐analytic evidence is discussed. Third, the role of the adoptive family in supporting adopted children's development is explored.  相似文献

In this article, teachers' sense-making and reasoning about higher education reforms in a post Soviet country, namely Armenia, are examined using an analytical framework with six sensitising concepts: beliefs, emotions, attitudes, change knowledge, attributions and organisational culture. The results of semi-structured interviews with 12 Armenian higher education teachers showed that they mainly felt distrust towards reforms and that the implementation initiatives caused dissatisfaction, frustration and therefore distortion. At a deeper level, the teachers mostly felt excluded from the reform process and that their role was depreciated. One striking feature was the predominant causal attribution of teachers to external, unstable and uncontrollable factors which question the success of the reforms.  相似文献

The goal of this study was to explore the processes of group role formation in online class settings. Qualitative analysis was used to code chat logs and discussion threads in six undergraduate Family and Consumer Sciences online courses that required online group projects. Four themes related to the process of group role formation emerged: testing the waters, apologies as being nice, tag – you’re it, and struggling to find one’s role. Students created roles of leader, wannabe, spoiler, agreeable enabler, coat‐tails, and supportive worker as the group process evolved over the course of the semester. Results lend support for a balance between allowing students to create and experience roles on their own and faculty assignment of roles. Questions are raised related to faculty approaches toward directing and scaffolding the group process.  相似文献

This paper presents a game of industrialisation, based on a paper airplane, that mimics real world production ramp-up and blends classical engineering courses together. It is based on a low cost product so that it can be mass produced. The game targets graduate students and practitioners in engineering fields. For students, it offers an experiment in which methods learned in separate courses can be applied. For practitioners, it affords an opportunity to engage in reflexive practices related to industrialisation. Both students and practitioners are able to experience integrated management, required by industrialisation, in a controlled environment: the laboratory.  相似文献
