Background: Students on health and social care degree programmes spend 50% of their time on practice placements. Because of the diversity of settings and the need to evidence their work, it is vital to understand the information and resource needs of placement students. Objectives: The aim of this investigation was to understand the needs of placement students in terms of accessing resources whilst they are in the field in order to inform a guide to meet these needs. Methods: Focus groups were conducted with students on midwifery, social work and post‐registration health professions degree programmes on three different sites across the region. Data were analysed using Thematic Content Analysis. Results: Three themes emerged from the data: inequality, user education needs and students’ solutions and strategies. Conclusions: It is essential to speak to placement students in order to understand their needs in terms of accessing and using library resources. The timing and content of information skills training is key to meeting student needs while on placement.  相似文献

Objective: The research analyzes usage of a major biomedical library''s pre-1993 print journal collection.Methodology: In July 2003, in preparation for a renovation and expansion project, the Biomedical Library at the University of California, San Diego, moved all of its pre-1993 journal volumes off-site, with the exception of twenty-two heavily used titles. Patrons wishing to consult one of these stored volumes could request that it be delivered to the library for their use. In the spring of 2006, an analysis was made of these requests.Results: By July of 2006, 79,827 journal volumes published in 1992 or earlier had been requested from storage. The number of requests received declined with age of publication. The usage distribution exhibited a “long tail”: 50% of the 79,827 requests were for journal volumes published before 1986. The availability of electronic access dramatically reduced the chance that corresponding print journal volumes would be requested.Conclusions: The older biomedical print journal literature appears to be of continued value to the biomedical research community. When electronic access was provided to the older literature, demand for older print volumes declined dramatically.

Highlights

  • Analysis of requests for stored biomedical journal volumes published prior to 1993 indicates that older biomedical journal literature receives substantial use: during this 3-year study, there were nearly 80,000 requests for journal volumes published in 1992 or earlier, with half the requests for volumes published from 1986–1992 and 40% of the request for volumes published from 1970–1985. These results indicate that retaining older print volumes, or providing easy access to the older literature through electronic journals or other means, will likely be required to meet user information needs.
  • Use of older journal volumes varies by title and by user population, and a small number of journal titles were responsible for most of the use.
  • Requests for older print biomedical journal titles dropped significantly when electronic access became available.

Implications

  • Biomedical libraries should carefully consider implications of eliminating on-site access to older journal literature for users and budgets.
  • Removing access to older journal literature may result in higher demand for interlibrary loan and document delivery services.
  • Biomedical libraries can safely substitute reliable electronic access to older literature to meet ongoing needs for this information, thereby creating space for other purposes.

ABSTRACT— This report summarizes findings from a study of educators' views on the role of the brain in education. Responses were sought using questionnaires ( n = 189), followed by a smaller number of in-depth interviews ( n = 11). Results show a high level of enthusiasm for attempts to interrelate neuroscience and education, although conceptualizations about what this entails differ widely. Findings suggest that communication with practitioners may become a key factor influencing the success of attempts to enrich classroom practice with scientific understanding about the brain and mind.  相似文献

This case study describes the creation of a leisure reading collection in the Clifford Whitworth library at the University of Salford. It briefly surveys existing literature on leisure reading collections and looks at the growing interest among U.K. academic libraries in recreational reading. It considers the reasons for promoting reading as a leisure activity to students and describes the processes of selecting, purchasing, and marketing the collection at Salford. It also considers possible future developments for the collection and the evaluation of the library's attempts to encourage a culture of reading among Salford students. The positive response to the collection suggests the development of leisure reading is a worthwhile activity for academic libraries to focus on and the study contains useful information for others who are interested in creating a similar collection.  相似文献

This essay proposes using a wheel or circular calendar to identify and document the events and projects of an academic law school year, both in and out of the classroom. The idea of harnessing the natural cyclical process of law school for library planning comes from concept mapping, which can conceptualize an issue by using a variety of mapping strategies to organize and show the relationships between pieces of information and a central concept. Using a wheel graphic to visualize a process can facilitate project management and aid in teaching legal research strategy.  相似文献

Although the participation by females in upper-level occupations and positions has expanded considerably in recent years, science is still considered a masculine career field. The results of this study show that only the physical sciences in particular (not science in general) are clearly viewed as masculine academic areas. Furthermore, the results suggest that the perception by girls of the physical sciences as masculine is much more likely to occur in coed classes than in all-female classes. The results can best be explained by two factors: (1) the attitudes conveyed by teachers and by society may predispose students toward a greater acceptance of women in biology than in the physical sciences; and (2) when girls perceive themselves as a deviant minority in physical science classes, their performance and preference for the physical sciences is reduced, perhaps because of competition and comparison with males. In all-female classes, however, girls are not a deviant minority, and therefore they are able to perform and develop preferences without inhibition.  相似文献

Selecting Books for Children Birth Through Four: A Developmental Approach   总被引:1,自引:1,他引:0  
The selection of books to read to young children matters enormously in the role books play for enriching children’s lives. This paper reviews the scientific evidence for the appropriate selection of books, and argues that care in selecting books targeted to children’s developing skills will enhance the power and the pleasures of reading to young children.  相似文献
