In South Africa the education system for black children is fraught with problems. These problems are the direct result of apartheid and have been compounded by poverty and illiteracy. In this article the problem of poorly qualified or unqualified teachers is discussed especially with regard to the teaching of map skills to children in their fifth school year. The project team needed to develop affordable materials which could be used in large classes by teachers after a very short period of training. Books and other materials which are available commercially were examined, but for various reasons were found to be unsuitable for local conditions. After determining the extent of the problem, the project team followed a grassroots process of developing a flip chart which teachers learnt to use with confidence and which enabled pupils to master the concepts and skills necessary for understanding a map. 相似文献

OBJECTIVES: The purpose of this study is to determine how personal digital assistants (PDAs) are used on an academic health sciences campus to define the level of training and support the library can provide to the students and faculty. METHOD: A Web-based questionnaire was developed. A total of 1,538 health sciences faculty and residents were sent an email message requesting participation. Data from the returned surveys were analyzed with SPSS. RESULTS: Sixty-one percent of survey respondents used PDAs. The address book, date book, and calculator were the most common uses reported for PDAs. Residents also reported a high use of drug databases on their PDAs. Most survey respondents indicated they would like to learn more about clinical resources for PDAs. CONCLUSIONS: Many opportunities exist for librarians to provide training and support for PDAs, in addition to evaluation and promotion of clinical software for PDAs. 相似文献

PURPOSE: The purpose was to determine the impact of online journals on the citation patterns of medical faculty. This study looked at whether researchers were more likely to limit the resources they consulted and cited to those journals available online rather than those only in print. SETTING: Faculty publications from the college of medicine at a large urban university were examined for this study. The faculty publications from a regional medical college of the same university were also examined in the study. The number of online journals available for faculty, staff, and students at this institution has increased from an initial core of 15 online journals in 1998 to over 11,000 online journals in 2004. METHODOLOGY: Searches by author affiliation were performed in the Web of Science to find all articles written by faculty members in the college of medicine at the selected institution. Searches were conducted for the following years: 1993, 1996, 1999, and 2002. Cited references from each faculty-authored article were recorded, and the corresponding cited journals were coded into four categories based on their availability at the institution in this study: print only, print and online, online only, and not owned. Results were analyzed using SPSS. RESULTS: The number of journals cited per year continued to increase from 1993 to 2002. The results did not indicate that researchers were more likely to cite online journals or were less likely to cite journals only in print. At the regional location where the number of print-only journals was minimal, use of the print-only journals did decrease in 2002, although not significantly. CONCLUSION/DISCUSSION: It is possible that electronic access to information (i.e., online databases) has had a positive impact on the number of articles faculty will cite. Results of this study suggest, at this point, that faculty are still accessing the print-only collection, at least for research purposes, and are therefore not sacrificing quality for convenience. 相似文献

Public visual spaces, populated by a blend of community murals, unauthorised street art, and historic painted mercantile signs, are often the mark of an urban environment that is both progressive and eclectic. Changes in the aesthetic and cultural value of these urban mural forms have led to an increase in the appreciation and, in some instances, promotion of their artistic merit and cultural significance as examples of public art. However, examining the significance of these works, with a view to implementing a conservation approach is problematic. This is due to a number of practical and theoretical considerations that are primarily a result of the ephemeral existence of urban murals outside conventional exhibition spaces, and issues associated with their often fragmented ownership and uncertain authorship. Consequently, larger thinking on the interpretation, conservation assessment, and advocacy for the conservation of urban murals are required. Key to defining and implementing such strategies is contextualising the public visual spaces that these murals occupy and, as part of this, the local and wider communities’ perception of these murals as culturally significant objects as well as fostering awareness and understanding of appropriate measures aimed at their conservation. This paper examines the role of citizen science, or crowd-sourcing, of local community members in establishing a conservation dialogue and generating conservation- relevant data on urban murals. It looks specifically at a project involving a collection of in situ historic painted mercantile signs — also known as ghost signs — in the City of Port Phillip, Melbourne, Australia. The project fostered the establishment of an informed and open dialogue between conservation specialists and participants from the local community on the significance of local ghost signs whilst transferring knowledge on conservation processes and assessment methods. Working directly with community members, a programme was designed in which conservation and community knowledge of these urban art forms, could be collected and exchanged across digital platforms. This enabled researchers to examine how citizen science can be utilised as a research tool as well as a means to advocate for the conservation of collections of urban murals. It created the opportunity to consider the role of non-specialists and shared authorities in the collection and collation of conservation- relevant data and how information generated from what we call citizen conservation projects, can inform the way in which conservators evaluate and prioritize the conservation of urban cultural heritage. The data gathered and interpreted proved to be the most effective means of ‘conserving’ these often ephemeral forms of cultural material. 相似文献

There is a growing trend toward a consolidation of services for electronic resources management, A–Z journal listings, full text link resolving, and discovery services under a single service provider. In many cases, the adoption of a discovery service from a provider that is not the same as the libraries’ existing link resolver service means managing multiple knowledgebases. In this session, three librarians gave an overview of their experiences and strategies for maintaining separate link resolving and discovery services in lieu of adopting a full suite of services from a single service provider. Each speaker presented a case study on the advantages and challenges of managing their chosen discovery service: EBSCO Discovery Service, Ex Libris’ Primo and ProQuest’s Summon, in conjunction with the CUFTS/GODOT open source knowledgebase and link resolver service. 相似文献

Extended families of 12 young adults (9 LD, 3 non-LD) were given a battery of tests and questionnaires, and 131 persons, ranging
in age from 6 to 85, were classified as LD or non-LD on the basis of subtest scores 1 SD below the mean or less on subtests
of the PIAT and WRAT achievement tests. Pedigree analysis indicated that LD was strongly familial, with the most probable
mode involving a major gene effect, but the type of disability (reading/ math) was not directly inherited. Autoimmune disorders
were significantly correlated (P<.005) with LD, especially in families in which LD remained a major handicap into adulthood,
a trait that also varied between families. In two of the LD families, adults showed little evidence of the reading/spelling
deficits they had shown when tested as children, while adults in other families failed to make gains in reading and spelling. 相似文献

There appear to be unconditioned affective reactions to the four basic tastes: liking for sweet and salt and disliking for sour and bitter. We attempted to modify these reactions by pairing the tastes with calories and with sweeter tastes. Differing sucrose concentrations were ineffective in reversing the preference for salt over citric acid or for saccharin over quinine. We could, however, reverse the preference for salt over citric acid, producing an actual preference for sour over salt, by using sucrose and saccharin as the reinforcers. The initial reactions to tastes could also be modified by reducing the initial difference in affect produced by the tastes through mixing both tastes with sucrose. 相似文献

Mathematics education is a critical part of the curriculum for students worldwide. The foundation for understanding mathematical
concepts related to number sense begins early in life, and early childhood classrooms can provide the seeds for mathematical
skills that will be needed later in life. In this article, the authors make a case for meaningful and developmentally appropriate
mathematics experiences for young children in diverse early learning settings. Instructional and curricular methods inspired
by the Reggio Emilia Approach are described as effective ways to teach number concepts to young children from preschool through
primary age. Strategies for teachers of young learners are presented in order to strengthen the mathematics curriculum in
contemporary early learning settings. The authors’ analysis and recommendations are informed by their extensive experiences
including studies in Reggio Emilia early childhood settings (infant toddler, preschool, and primary schools) and their work
in early childhood teacher education at their respective universities. 相似文献
