The article traces the career of Frederick G. Kilgour (1914–2006), who is widely recognized as one of the leading figures in 20th-century librarianship. He founded the Ohio College Library Center (OCLC) and from 1967 to 1981 was its first president and chief executive officer, presiding over OCLC's rapid growth from an intrastate network to an international network. In 1971, under Kilgour's leadership, OCLC introduced an online shared cataloging system and an online union catalog (WorldCat) that is today the world's foremost bibliographic database. In 1978, he created the OCLC Office of Research, and in 1979, under his direction, OCLC launched its online interlibrary loan system. The author of 205 scholarly papers, Kilgour received numerous awards and honors over the course a career that took him from Harvard University Library, to the Office of Strategic Services in World War II, to Yale Medical Library, to OCLC, and finally, to the University of North Carolina at Chapel Hill, where he spent his final years on the faculty of the School of Information and Library Science as a Distinguished Research Professor.  相似文献

Abstract

Much has been written about the problems associated with reliance on extrinsic rewards and punishment in controlling behavior and motivating students. This study explores the use of extrinsic rewards and punishment by prekindergarten ‐ grade 3 teachers in Missouri. The purpose of the study was to (a) determine the most common motivational practices and classroom management strategies being used by prekindergarten ‐ grade 3 teachers; (b) determine the range of costs of rewards given to children and the source of these funds; (c) determine administrative and parental support; and (d) determine what influenced the teachers’ choices of behavior management strategies. Results of the study indicated that a significant majority of the respondents chose good instructional practices of the teacher as having the most positive influence on child behavior. However, most of the teachers responding continued to use extrinsic rewards and punishment to achieve acceptable behavior management and student motivation. In addition to reviewing the recent literature on extrinsic rewards and punishment, the authors discuss the implications of the findings for teacher educators and for those responsible for professional development programs for teachers. © 2005 Elsevier Inc.

Abstract

The concepts of exercise as presented in De sanitate tuenda (Care of Health), 1560, written by the Renaissance physician, Girolamo Cardano (1501–1576), were the focus of the inquiry. In this work, as well as in his personal and professional life, Cardano was an advocate of physical activity for the development of physical and mental well-being. The benefits accrued from participation were: the harmonious development of mind and body; good health; emotional stability; a strong, firm, beautiful body; and a long, robust life. Physical exercise was perceived as a lifelong task ranging from childhood to old age, with activities geared for the needs and limitations of each age grouping. Vigorous activities were recommended for both children and youth. As one grew older, moderate physical exercise with longer rest periods was advised. A comparison of this work with Sir Thomas Elyot's Castel of Helth, 1541, revealed that Cardano was significant in the realm of Renaissance exercise for his advocacy of physical exercise for all ages, particularly the forty to seventy age group, as well as for the delineation of appropriate activities for this older adult group.  相似文献

Although associations between socio-economic status, race, and academic achievement are well established, the specific mechanisms that underlie the relation remain incompletely understood. This longitudinal investigation, involving a sample of 206 children from economically and racially diverse backgrounds, examined the influence of executive function and expressive vocabulary assessed in kindergarten on academic achievement in Grade 1. The use of structural equation modeling revealed that both SES and race had indirect effects on achievement test scores through their effects on executive function, even when accounting for differences in expressive vocabulary. As expected, executive function was more strongly related to math than literacy achievement. The results provide support for the importance of targeting executive skills and intervening early in efforts to improve academic performance in young children. Moreover, the findings suggest that improving executive function may mitigate the impact of social risk factors on academic achievement.  相似文献

Transitive thoughts are the feeling tones, rhythms and idiosyncrasies that are communicated in speech. They are important sources of information for counsellors and their clients. Q methodology is presented and discussed as applicable to counselling education in its ability to give meaning to transitive thought. Relevance to counsellor education is based on the assumption that it is important to assist counsellors in intentionally developing self‐knowledge as an essential part of their practice. Through explicitly structuring and analysing transitive thought, Q methodology makes it possible to discover its underlying patterns. Those patterns can be subsequently interpreted and given meaning through dialogue, thus leading to a more holistic understanding of thought. Q methodology is suggested as a useful systematic approach for counsellors to learn about themselves and to include the feeling part of thought in their practice.  相似文献

This article reports on recent findings from a mapping study of Personal, Social, Health and Economic (PSHE) education in schools in England, focusing on the data derived from primary school participants. It is based on a nationally representative survey of 923 primary school PSHE education leads, and follow-up in-depth interviews and discussion groups with 171 participants. This included local authority support staff, and from participating primary schools: senior management representatives, PSHE education leads, teaching staff, governors, school improvement partners, parents, and pupils. Results included here primarily relate to two areas: delivery models and curriculum coverage, and pupil views on their experiences and the (potential) value of PSHE education. In examining these areas, the article raises issues about blurred boundaries between PSHE education and Social and Emotional Aspects of Learning and/or pastoral care within school more widely, and particular staff sensitivities about the teaching of certain elements of PSHE education, particularly sex and relationships education and drugs, alcohol and tobacco education. These subject areas were less likely to be included or prioritised within PSHE education than, for example, emotional health and well-being, but were often the areas highlighted as most important by pupils. In conclusion, the article raises questions about the potential links between PSHE education and attainment, and the use of different teaching approaches across the curriculum more broadly.  相似文献

The analysis and interpretation of data are important life skills. A poster challenge for schoolchildren provides an innovative outlet for these skills and demonstrates their relevance to daily life. We discuss our Statistics Poster Challenge and the lessons we have learned.  相似文献

Data from the North Carolina End-of-Grade test of eighth-grade mathematics are used to estimate the achievement results on the scale of the National Assessment of Educational Progress (NAEP) Trial State Assessment. Linear regression models are used to develop projection equations to predict state NAEP results in the future, and the results of such predictions are compared with those obtained in the 1996 administration of NAEP Standard errors of the parameter estimates are obtained using a bootstrap resampling technique.  相似文献
