Information policy research is a critical tool in the arsenal of library and information science researchers. As developments occur in information access, use, technology, and management, information policies require more attention and research. The article describes the nature of government information policy and policy research, characteristics of policy research, and examples of research methods and approaches that can be used. The differences between textbook-based policy research and how policy research might be implemented in action are also discussed, as are the inter-connectedness of information policies and ways to describe impacts of information policies. The article recommends that researchers and professionals give greater education, training, and professional association attention to using policy research on a day-to-day basis. 相似文献

This article presents an overview of the methods, findings, and the general implications of the 2007 Public Libraries and the Internet study. This annual study has chronicled public libraries' provision of Internet access to patrons and a range of related issues since the early 1990s. The 2007 study focused on the provision and maintenance of Internet access and services, infrastructure issues, community impacts of the technology, training, library technology funding, and e-government roles of public libraries. This article details these findings, exploring how the 2007 data compare to previous studies. It also considers the implications of these comparisons in terms of the levels of service that libraries are able to provide, the challenges that libraries face in providing these services, and the ways in which communities and governments rely on public libraries to guarantee public Internet access. 相似文献

Abstract Many activities from the infant class curriculum may be enhanced by realising them in the interactive context of a computer environment. This raises the question of whether young children can make choices among such activities that would reflect an awareness of their difficulty and a motivation to master them. In this research, infant class pupils were provided with software that offered unconstrained opportunities to select a range of related activities and the level of difficulty at which they would be tackled. Choices and response times were automatically recorded over a period of three weeks. These choices remained stable throughout that time and were biased towards the easiest options. There was some improvement in performance although little evidence of choice strategies that could be effective in driving such improvement. There was no evidence of sex differences in frequency of using the computer. 相似文献

AbstractAn increasing number of K–12 schools have adopted blended learning approaches. Current empirical research has been sparse regarding preparing teachers for blended teaching, including the skills they must develop to teach in blended contexts. This research is focused on that weakness, with the purposes of systematically identifying the skills needed for teaching in a blended learning context and of developing and testing an instrument that can be used to determine individual and school-wide readiness for blended teaching. In this study we present a measurement model used to develop items for measuring K–12 blended learning readiness. Specifically the instrument contained the following top-level areas: (a) foundational knowledge, skills, and dispositions, (b) instructional planning, (c) instructional methods and strategies, (d) assessment and evaluation, and (e) management. Each top-level construct also had two to four subconstructs. Through confirmatory factor analysis using survey responses from 2,290?K–12 teachers we found that the data met all four fit statistics cutoffs set forth in the literature (root mean square error of approximation [RMSEA]= 0.041, comparative fit index [CFI]?=?0.926, Tucker–Lewis index [TLI]?=?0.923, standardized root mean square residual [SRMR]?=?0.041, X2?=?978.934, df?=?1992). 相似文献

Recent research on student learning has given close attention to how students experiences and actions are mediated by the whole university learning–teaching environment in which they find themselves. The current article pursues this focus on learning–teaching environments in two stages. Guided by socio-cultural perspectives on learning, the first part:
The second part of the article then engages with the task of illustrating how this general framework (which foregrounds disciplinary concerns) can be applied within a specific subject. The framework is employed to structure an account of the insights gained from an ongoing research study concerning:

Two experiments demonstrate that individual differences among normal adult readers, including lexical quality, are expressed in silent reading at the word level. In the first of two studies we identified major dimensions of variability among college readers and among words using factor analysis. We then examined the effects of these dimensions of variability on eye movements during paragraph reading. More experienced readers (who also were higher in reading speed) read words more quickly, especially less frequent words, while readers with higher lexical knowledge showed shorter early fixations, especially for more frequent words. These results suggest that individual differences in reading may reflect differences in the quality of lexical representations and in reading experience, which is a source of lexical quality. In a second study, we controlled the lexical knowledge readers obtained from new words through a training paradigm that varied exposure to a word’s orthographic, phonological, and meaning constituents. Training exposure to orthographic and phonological constituents affected first pass reading measures, and phonological and meaning training affected second pass measures. Incomplete knowledge of word components slowed first pass reading times, compared to both more complete knowledge and no knowledge. Training effects were mediated by individual differences, pointing to lexical quality and reading experience—which, combined reflect reading expertise—as important in word reading as part of text reading. 相似文献

Child Development and Neuroscience 总被引:7,自引:0,他引:7
Although developmental psychology and developmental neuroscience share interests in common problems (e.g., the nature of thought, emotion, consciousness), there has been little cross-fertilization between these disciplines. To facilitate such communication, we discuss 2 major advances in the developmental brain sciences that have potentially profound implications for under standing behavioral development. The first concerns neuroimaging, and the second concerns the molecular and cellular events that give rise to the developing brain and the myriad ways in which the brain is modified by both positive and negative life experiences. Recurring themes are that (1) critical, new knowledge of behavioral development can be achieved by considering the neurobiological mechanisms that guide and influence child development, and (2) these neurobiological mechanisms are in turn influenced by behavior. 相似文献
