Phonological awareness, phonological memory, and phonological access to lexical storage play important roles in acquiring
literacy. We examined the convergent, discriminant, and predictive validity of these phonological processing abilities (PPA)
in 389 3-, 4-, and 5-year-old children. Confirmatory factor analysis supported the validity of each PPA as separate from general
cognitive ability and separate from each other. Multigroup structural equation modeling (SEM) with mean structure demonstrated
that older preschoolers have better developed latent PPA than younger preschoolers but that the structure of PPA is equivalent.
RAN was found uniquely associated with letter knowledge and text discrimination in younger preschoolers, and PA was found
uniquely associated with word reading skills in older preschoolers. Finally, general cognitive ability was only indirectly
associated with emergent literacy via PPA. These results highlight the importance of PPA in the early literacy development
of English-speaking preschool children. 相似文献

Small programs can make a big difference on college campuses. At Duke University, a few dedicated people, with the support
of college administrators, exploited the all-too-evident liabilities of curriculum fragmentation, political correctness, and
the lack of direction felt by undergraduate students to create intellectually valuable and stimulating new offerings. Russell
Nieli tells how the Gerst and Focus programs have influenced that university and others across America.

"非形式逻辑"作为逻辑的子领域,最初出现于1970至1980年代的美国和加拿大,本文意在回顾非形式逻辑发展的早期历史进程.本文假定,当我们从历史的角度来考察时,非形式逻辑的本质能够得以阐明.因此,我将以观念史领域的评论作为出发点.之所以不从理论的要素谈起并把历史留给历史学家,其中一个理由在于"非形式逻辑"这个词并不指示一个理论.非形式逻辑部分地可看作是某个思潮,部分地可当作一种论证研究进路,部分地涉及到对逻辑之本质的看法,这些都可以通过考察非形式逻辑的发展史来加以理解.本文的第一部分追溯了非形式逻辑的兴起,概括了其思想史和社会史,并评述了其早期发展中的主要人物、教科书,以及主要的论旨及其社会化.第二部分简要描述了<逻辑的自我辩护>这本教科书中的一些革新.第三部分简要涉及非形式逻辑与其它领域的早期互动. 相似文献

Education policy increasingly promotes action groups as a key strategy for student and/or staff participation in school improvement and whole-school health promotion. Such groups can coordinate multi-component interventions, increase participation and engagement, and enable local adaptations, but few process evaluations have assessed this. We evaluated fidelity, feasibility and acceptability of action groups as part of a trial of a whole-school intervention to reduce bullying and aggression and promote health in English secondary schools, which reported multiple health and educational impacts. Action groups involved students and staff, supported by external facilitators, and drew on data on student needs. They aimed to: coordinate implementation of restorative practices and a social and emotional competencies curriculum; review policies and rules; and enact local decisions to modify school environments. Our process evaluation used interviews, focus groups, observations and questionnaires to assess action groups’ fidelity, role in coordination, role in local adaptation, support from external facilitators and data on student needs, and acceptability in engaging members. Fidelity was high in the first two years but lower in the third year when external facilitators withdrew. Student needs data were perceived as useful, but views on external facilitators were mixed. Groups successfully reviewed policies and rules, planned activities and coordinated restorative practices, but were less successful in implementing the curriculum. Success was facilitated by the involvement of school leaders. Members reported high satisfaction and empowerment. Action groups are a promising strategy for leading whole-school health promotion. Implementation is supported by external facilitation, local data and involvement of senior managers. 相似文献

This qualitative study was undertaken to explore what undergraduate students reflect on during their learning to practice social work in the field. Reflection is essential in the social work field practicum where students learn the practice of social work by doing. Seventeen BSW students’ final field practicum learning papers are analyzed. Four themes emerge that highlight the content of their reflections: situations of uncertainty, opportunities for application, tensions in action, and confrontations with others. This article presents in detail these 4 themes. Discussion includes suggestions for helping students better engage in reflective learning. 相似文献

The word “empowerment” is associated with several different and fundamentally inadequate paradigms. This paper presents an alternative, empowering view of empowerment. The essence of empowerment is increasing the behavior potential of persons, individually and in groups and organizations. Behavior potential is not some abstract concept of “what a person might do if” Instead, it is the totality of behaviors that are actually available to a given person in a given environment. These behaviors do not occur in a vacuum; behavior potential is the intersection of the person's behavioral productions with the organization's expectations and permissions. An individual is empowered to the extent that he or she possesses a rich repertoire of behaviors and is expected and permitted to make full use of this repertoire by the organization. 相似文献

BackgroundOne-hour postprandial hyperglycemia is associated with increased risk of type 2 diabetes and cardiovascular disease. Physical activity (PA) has short-term beneficial effects on post-meal glucose response. This study compared the oral glucose tolerance test results of 3 groups of people with habitually different levels of PA.MethodsThirty-one adults without diabetes (age 25.9 ± 6.6 years; body mass index 23.8 ± 3.8 kg/m2; mean ± SD) were recruited and divided into 3 groups based on self-reported PA volume and intensity: low activity < 30 min/day of moderate-intensity activity (n = 11), moderately active ≥ 30 min/day of moderate-intensity PA (n = 10), and very active ≥ 60 min/day of PA at high intensity (n = 10). Participants completed an oral glucose tolerance test (50 g glucose) with capillary blood samples obtained at baseline, 15 min, 30 min, 45 min, 60 min, 90 min, and 120 min post-ingestion.ResultsThere were no significant differences between groups for age or body fat percentage or glycated hemoglobin (p > 0.05). The groups were significantly different in terms of baseline glucose level (p = 0.003) and, marginally, for gender (p = 0.053) and BMI (p = 0.050). There was a statistically significant effect of PA on the 1-h postprandial glucose results (p = 0.029), with differences between very active and low activity groups (p = 0.008) but not between the moderately active and low activity groups (p = 0.360), even when baseline glucose level and gender differences were accounted for. For incremental area under the curve there was no significant effect of activity group once gender and body fat percentage had been accounted for (p = 0.401). Those in the low activity group took 15 min longer to reach peak glucose level than those in the very active group (p = 0.012).ConclusionThe results suggest that high levels of PA have a beneficial effect on postprandial blood glucose profiles when compared to low and moderate levels of activity. 相似文献
