The present study investigates the validity of a 4‐point rating scale used to measure the level of preschool children's orientation to literacy during shared book reading. Validity was explored by (a) comparing the children's level of literacy orientation as measured with the Children's Orientation to Book Reading Rating Scale (COB) with a teacher's rating of a child's level of attention and effortful control on the Children's Behaviour Questionnaire (CBQ), and (b) computing the predictive validity of a child's COB rating with overall levels of emergent literacy at the end of the preschool school year. This study involved 46 preschool children from low‐income backgrounds; children's literacy orientation was rated during a group teacher‐led book reading. Children's ratings of literacy orientation during shared book reading using the global 4‐point COB scale were significantly correlated with teacher ratings of a child's attention and effortful control as measured on the CBQ. Hierarchical regression results indicated children's literacy orientation significantly predicted children's end‐of‐year alphabet knowledge and overall emergent reading skills above and beyond the variance contributed by children's language skills and family income. The validity of a global rating for indexing children's level of literacy orientation was supported. Educational implications and recommendations for the COB as a component of early literacy assessment are discussed. 相似文献

Results of a 2 (immediacy conditions) X 3 (attire conditions) experimental study indicated lesser effects of attire on person perceptions when studied in a live interaction context as opposed to responses to photographs, as has been typical in previous studies. Influence of attire was largely limited to ratings of instructor extroversion, while immediacy influenced perceptions of extroversion, composure, character, competence, homophily, and learning. There was no statistically significant interaction between attire and immediacy; i.e., there was no indication that strategic choice of attire bolsters student ratings of non‐immediate instructors, or that “non professional” attire hurts judgements of immediate instructors. 相似文献

This article studies a television market where operators can sell access to programs and to advertising time. First, we determine the retail prices paid by viewers and advertisers to a monopoly platform when there are externalities between these two markets. We compare the prices that an unregulated platform would establish with the welfare maximizing prices. Second, we obtain the access charge that an independent programmer should pay to a television platform for using one of his channels. We show that the optimal access charge takes into account the direct cost of access and the platform's opportunity costs in the viewer and advertiser markets, which are affected by the externalities between the two markets. 相似文献

ABSTRACT This article highlights key events in the relationship between OCLC Online Computer Library Center, Inc. and the Dewey Decimal Classification (DDC) system. The formal relationship started with OCLC's acquisition of Forest Press and the rights to the DDC from the Lake Placid Education Foundation in 1988, but OCLC's research interests in the DDC predated that acquisition and have remained strong during the relationship. Under OCLC's leadership, the DDC's value proposition has been enhanced by the continuous updating of the system itself, development of interoperable translations, mappings to other schemes, and new forms of representation of the underlying data. The amount of categorized content associated with the system in WorldCat and elsewhere has grown, as has worldwide use of the system. Emerging technologies are creating new opportunities for publishing, linking, and sharing DDC data. 相似文献

In previous work with mainstream students in a small Interactive Science Centre it was shown that curiosity, followed by identification of cause and effect, were essential for moving on from playing to intentional investigation and so to learning. Here we report studies of students with severe learning difficulties and show that they could, under appropriate conditions, display impressive concentration and curiosity, and often appeared to achieve valuable learning. The paper concludes by describing some of the dilemmas that may arise in developing these kinds of activities for special education. 相似文献

In the wake of accreditation cycles stressing student outcomes, we believed the reflective and practitioner-centered philosophy of action research a perfect fit for effecting institutional improvements for a four-year grant-funded effort in our urban–suburban community colleges in California. We learned that things were both worse and better than we had imagined. While we had anticipated what we will call ‘the Bad’, the classic budgetary and institutional forces buffeting us, our project, and our institutions, we had not anticipated what we will call ‘the Ugly’. And perhaps because of our grasp of ‘the Bad’, we also had not anticipated what we will call ‘the Good’. We found ourselves challenged to rethink how to encourage colleagues to become reflective practitioners, yet able to appreciate the power of action research to lead to genuine transformation. 相似文献

Five ratios RH, RT, SH, ST and SZ derived from the three-part division of a set of sources in h-core, h-tail and uncited sources are defined. Dynamic changes in the three independent ratios RH, SH and SZ are studied for six selected topics. Data about these topics are obtained from the Web of Science for scientific papers and Derwent Innovations Index for technical patents. It is observed that all RH- and SH-values decrease when the time span widens, while SZ stays the same or increases; and that all RH- and SH-values for papers are larger than the corresponding values for patents. The shifted Lotka distribution is used in a theoretical interpretation of these empirical phenomena. 相似文献

The purpose of this paper is to explore the literature on the status of women's health behavior and the benefits of physical activity using Self-Determination Theory (SDT) as an organizing framewrok for syntbcsizing and interpreing the extant research. The Health Belief Model and the Transtheoretical Model (Stages of Change) are included in that framework. Women's physical activity behaviors are examined through the lens of SDT with the intention of identifying strategies to design theoretically based intervention programs to increase women's participation in physical activity. Interventions that have been succcessful in modifying exercise behavior in women have been characterzed as individualized, flexible, and tailored to meet women's specific needs. SDT can be used to direct future research by investigating how autonomy, relatedness, and competence can be incorporate in program to increase women's self-determination with regard to heir physical activity and ultimately facilitate internalized, intrinsic motivation leading to loag-term behavior change 相似文献
