OBJECTIVES: Despite the growing use of online databases by clinicians, there has been very little research documenting how effectively they are used. This study assessed the ability of medical and nurse-practitioner students to answer clinical questions using an information retrieval system. It also attempted to identify the demographic, experience, cognitive, personality, search mechanics, and user-satisfaction factors associated with successful use of a retrieval system. METHODS: Twenty-nine students completed questionnaires of clinical and computer experience as well as tests of cognitive abilities and personality type. They were then administered three clinical questions to answer in a medical library setting using the MEDLINE database and electronic and print full-text resources. RESULTS: Medical students were able to answer more questions correctly than nurse-practitioner students before and after searching, but both had comparable improvements in the number of correct questions before and after searching. Successful ability to answer questions was also associated with having experience in literature searching and higher standardized test-score percentiles. CONCLUSIONS: Medical and nurse-practitioner students obtained comparable benefits in the ability to answer clinical questions from use of the information retrieval system. Future research must examine strategies that improve successful search and retrieval of clinical questions posed by clinicians in practice. 相似文献

This study evaluates the use of full-text databases amongst 425 undergraduate and graduate students in western New York. A review of literature implicated convenience, time issues, article retrieval option knowledge, and the appreciation and understanding of research article quality as potential predictors of full-text reliance. These variables were then evaluated via survey response and frequency counts, by conducting correlations, a one-way ANOVA, and stepwise regression analyses. The findings suggested that convenience, appreciation and understanding of research quality, and time management issues played a significant role in the prediction of student full-text reliance. These findings as well as the relationships among independent variables are discussed. Implications for instruction are then addressed. 相似文献

AbstractThe researchers conducted a task-based usability test of the effectiveness of online research beginning on the library Web site homepage. The participants included five university faculty members, six graduate students, and six undergraduate students. All participants reported feeling satisfied with their overall research experience, though most were unable to effectively complete all the research tasks of the test. The researchers identified weaknesses in the approach and process of many participants, and overall usability issues of the library discovery tool and other library Web site pages and research interfaces. Findings indicate the need to strategically incorporate self-service information literacy and research skills help into the library Web site, and to implement navigation and design changes to the library homepage, discovery tool interface, online catalog, and across all the library's Web services. 相似文献

Abstract NOAH (New York Online Access to Health) is a Web site developed by four library partner organizations, in an effort to provide timely, accurate and unbiased health information to the health consumers in New York City in both English and Spanish. Since expanded to include two other partner organizations, NOAH continues, with the help of volunteer librarians, to expand and enhance the site, always with the mission to provide full-text health information in the most user-friendly method possible. 相似文献

The ever-growing number of full-text electronic databases and their increasing availability has helped to create greater expectations among the undergraduate students who use them in their research. A study was made of nearly three hundred students enrolled in composition classes to determine the indexes and databases most commonly used for assignments and whether having the full text of journal articles online played a role in shaping the nature of their research. The survey results confirmed the authors' belief from encounters at the reference desk that students are becoming dependent on the availability of full-text databases and are using them in some cases to the exclusion of all other information sources. 相似文献

AbstractMillennials, or Generation Y learners, are one of the largest constituencies academic libraries serve today. Understanding how and why these technology-savvy students learn increases the efficacy of information literacy instruction and ensures that libraries remain relevant in the digital age. This article addresses the complexity of the millennial learning phenomenon and its implications for instructional design and teaching in physical and virtual library environments. To situate millennial learning in the context of academic library instruction, this paper takes a large-scale, holistic approach that includes consideration of millennials’ learning styles, emerging technologies, and a multitude of other issues affecting Generation Y learning. 相似文献

This study investigates whether the platform used to deliver a tutorial matters in online information literacy instruction and assesses the overall quality of an information literacy tutorial assignment given to an undergraduate survey class. The study asks whether there is any pedagogical advantage between information literacy tutorials created in the LibGuides library guide creation software and tutorials created as Web pages. This research question is relevant to current studies of online information literacy tutorials, particularly given the increasingly dominant but under-researched position of LibGuides in the academic library world for delivering guides and tutorials. Two separate groups of students completed LibGuides and Web page versions of the same information literacy tutorial assignment in a university undergraduate communication course. Survey results of these 89 students indicated that both the LibGuides and Web page platforms deliver online instruction content effectively and achieve learning objectives almost equally well. Results also indicated content areas within the assignment that could be strengthened. 相似文献

ABSTRACT Digital collections of full-text e-books are proliferating on the Web and provide a wealth of open content for students. To examine whether academic libraries are providing a digital gateway to these resources, ten e-book titles from open digital collections were searched in the online catalogs and Web pages of ten academic libraries serving distance learners. Only three of the digital collection e-books were available from any of the library catalogs, and none were found on library Web pages. Availability of the ten e-book titles through Google and other digital discovery tools also had mixed results. Continued projects for improved delivery of open online content are necessary. In order to fulfill their role as digital gateways for their academic communities, libraries must pursue metadata standards to support cross-searching, collaborative projects, and development of e-resource search software, which integrates with the library catalog. 相似文献

SUMMARY There is a proliferation of Internet sites covering environmental themes. Many of these sites provide reference information in varying degrees. This article highlights environmental Web sites that provide a wide range of pertinent reference sources to a diverse audience. More than 50 highly selective Web sites are included in this paper. Some of these Web sites provide access to library catalogs, full-text articles, and other online resources. The Web sites in this article are in five categories: portals, government sites, special issues, general sites, and databases. 相似文献

The current generation of millennial university students is more accustomed to searching reference information online than visiting the physical library facility, compared to the previous generations of students. Studies have shown that the role of the physical library facilities as a mere collection point of reading and reference materials is being threatened by the availability of free and high-speed online search engines. University libraries have always been an integral part in higher education learning activities, and they are not exempted from this threat. Based on a structural equation modelling framework, we analysed empirically the importance of different library design features that help enhance students' learning satisfaction, and found that lighting environment, acoustic environment as well as location of the library building were the main determinants impacting on the use of the university library by students in a major university in China. We conclude the paper with our suggestions in modifying library design to accommodate students' learning needs, and more importantly in recon?uring the spatial and functional role of university libraries in this age of digital information from a mere provider of reference materials to a physical space of learning commons on campus. 相似文献

Abstract Library Web pages are increasingly designed to be the initial entry point for research, whether used from the library or off campus. But the pages must be intuitive and easy to use or students may bypass them completely, in favor of more familiar Web resources. This article presents the process, results, and evaluation of a Web usability study conducted at Linfield College with undergraduate participants. Web usability testing was a relatively quick and inexpensive way to find out how students used the library Web pages, information that proved invaluable in making effective modifications to them. In the process, researchers gained insights into student online searching and research patterns that have informed reference and teaching activities as well. 相似文献

Revisiting a study performed 30 years ago, researchers at three institutions surveyed undergraduate and graduate students in marketing courses to determine their attitudes toward and knowledge of library services and collections. Results found that 21st-century students are more likely to believe in the importance of library research, to have had library instruction, and to use Web sites and Internet search engines to begin their research. However, they are less likely to read business periodicals. Faced with a list of information sources, they are generally able to pick out a useful resource, although not always the most efficient. Implications for library service to business students are discussed. 相似文献
