The literature shows that students are more likely to begin their search via Google, as it is perceived to be easier and more accessible than other databases or publisher platforms. The invisible web, specifically publisher platforms, is sometimes too difficult for students to access; there are also suggestions that Google Scholar in particular may outperform other paid-for databases. The ease of access and the somewhat misguided notion that Google Scholar has more reliable information than that provided by libraries makes search engines all the more attractive. This culture of searching using a single search box is reflected in the increase in the number of libraries opting for single resource discovery systems such as Summon or Primo, which use a single search covering all the library holdings. The findings suggest that whilst Google Scholar can perform well in some circumstances, it performed only moderately well when compared with LISTA and Summon – the single resource discovery system tested. It was the least successful resource in terms of precision when compared with LISTA, Summon, Emerald and Sage. However, the simplicity of search engines begs the question: will databases and publisher platforms become obsolete? The study concludes that subject specific databases are more effective than search engines, but the complexity of accessing the invisible web is hindering their popularity. 相似文献

Making scholarly information visible to web search engines is an ongoing challenge, and undergraduate research is no exception. Using a sample of award-winning undergraduate history papers and journals, the authors searched Google, Google Scholar, Microsoft Academic, and the authors' institutional repository to gauge the difficulty of locating these works. Given that many of these works were not easily found, results suggest that libraries and their institutions could be doing more to increase the discoverability of undergraduate research. Based on the success stories observed in this study, we offer strategies to libraries and librarians for increasing the visibility of undergraduate student research. 相似文献

This article investigates how psychology graduate students find information for coursework and research, who teaches them how to find it, and whether differences emerge over the course of their graduate careers. Findings indicate that these graduate students are comfortable using campus libraries, prefer electronic resources, ask supervisors when they need assistance locating information, and have some interest in furthering their information literacy knowledge. Finally, the master's students use different information management skills than do the PhD students, as evidenced by the use of bibliographic management software. Suggestions for furthering the role of research librarians focus on being more proactive, rather than expecting students to come to librarians for assistance. 相似文献

This paper highlights the design and development process that two academic business librarians employed to create an online toolkit of eLearning supports for business students. After receiving funding from their institution’s internal teaching innovation fund, they hired and worked with two eLearning design companies to produce the toolkit. The toolkit includes videos and PDF resources that show students how to retrieve specialized resources for key business research tasks. The librarians undertook this project to increase the online business information literacy offerings at their university and better support their institution’s diverse commuter, distance, and part-time student population. To develop a student-centered toolkit, the librarians used a curriculum mapping exercise, online surveying, focus groups, usability tests, and a student review group. They also adapted the ADDIE instructional design model and consulted adult learning theory to develop a series of micro-learning supports that were relevant and useful for undergraduate and graduate business students. 相似文献

ABSTRACT Almost three years after Google Scholar's inception, only a third of Ohio Library and Information Network (OhioLINK) member libraries link to it from their Web sites. This article reports the results of a July 2007 survey of OhioLINK academic librarians, conducted to find out about their attitudes and current practices regarding promotion of Google Scholar. It compares the findings about placement of Google Scholar on Web sites and inclusion in library instruction with previous research, and includes recommendations for libraries about Google Scholar. 相似文献

Learning is critical to both economic prosperity and social cohesion. E-government learning, which refers to the government's use of web-based technologies to facilitate learning about subjects that are useful to citizens, is relatively new, relevant, and potentially cost-effective. This work proposes and verifies that the technology acceptance model (TAM) can explain and predict usage of e-government learning. The TAM examines how perceived ease of use and perceived usefulness and their antecedents influence intention and usage of a system. This study identifies antecedents that account for individual differences, thereby enhancing the explanatory power of the built model. A survey is used to collect data from users of an e-government learning website in Taiwan. Structural equation modeling is employed to examine the fit of the data to the model. From a theoretical point of view, this research extends the TAM to e-government learning and identifies the perceived e-government learning value and perceived enjoyment as antecedents of usage of e-government learning. This study also provides directions for future research and approaches to promote e-government learning. 相似文献

This paper outlines the case studies of two librarians who work closely with graduate students in fine arts programs. Realizing that graduate students can often experience a unique form of research anxiety, both librarians collaborated with faculty to embed themselves into the research methods courses of their programs. Both librarians found that the chance to work one-on-one with graduate students resulted in a reduction of their anxiety, an increase in information literacy skills, and a strengthened partnership between the librarians and the departments. 相似文献

In the 2015 Summer Session I, the information literacy team combined two instruments, the Information Literacy Assessment (ILA) and the Students' Perceptions of Their Information Literacy Skills Questionnaire (SPIL-Q), into one survey and distributed it to the college's international graduate students through a Google Form. It was distributed to 932 international graduate students, and 172 valid respondents completed the survey. The purpose of this research was to compare the confidence gap in information literacy skills between men and women, particularly in international graduate students. Data collected illustrated that female international business students (n = 70) tended to be slightly more confident than their male counterparts (n = 102) regarding their perceived information literacy skills as evidenced by their SPIL-Q average score across all six IL topics, 3.78, vs. male student's average score of 3.58. 相似文献

Despite the widespread application of technology in the 21st century, making informed decisions regarding its acceptance in organisations is a function of several factors, particularly in developing countries, due to factors such as rising cost of the information technology infrastructure and low technological exposure. A model that incorporated perceived ease of use (PEOU) and e-Skills to examine librarians' intention for actual library technology acceptance was tested. The correlational research design, along with a multistage sampling procedure, was applied to select samples to reduce the sample to a manageable proportion. Professional librarians and library officers in four university libraries provided the data for the study. Results showed that e-Skill is the model's strongest determinant of technology acceptance intention among librarians. Also, PEOU will significantly moderate librarians' intention towards library technology acceptance when e-Skills are insufficient. From these outcomes, the understanding of the determinants of behavioural intention captured in the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAT) is extended and refined. 相似文献

AbstractAs an alternative to large-scale outreach events, three public services librarians created a series of small-scale outreach events aimed at educating graduate students about library services and increasing positive perceptions of the library. The librarians ran five events with a 2:1 student-to-librarian ratio, and one event with a 13:1 student-to-librarian ratio. Using pre- and post-event surveys, the librarians evaluated student knowledge and perceptions of library services. Events of both sizes indicated that graduate students valued the outreach events and perceived increased comfort with the library following the events. However, the events with 2:1 ratios resulted in higher perceived comfort levels and more interest in scheduling follow-up appointments with librarians than the 13:1 ratio event. The researchers of this case study conclude that small-scale events have positive benefits for graduate students and that outreach assessment can be used to justify the increased time and cost commitments that are necessary for small-scale outreach events. 相似文献

This study used the Technology Acceptance Model (TAM) to examine taxpayers' acceptance of the Internet tax-filing system. Based on data collected from 141 experienced taxpayers in Taiwan, the acceptance and the impact of quality antecedents on taxpayers' perceived usefulness (PU) and perceived ease of use (PEOU) of the system were assessed and evaluated. The results indicated that the model of Internet tax-filing system was accepted with a reasonable goodness-of-fit. Three important findings include the following items. First, TAM proves to be a valid model to explain the taxpayers' acceptance of the Internet tax-filers' system. Meanwhile, PU has created more impact than PEOU on taxpayers' intention to use the system. Second, PU is positively influenced by such factors as information system quality (ISQ), information quality (IQ), as well as perceived credibility (PC). Third, IQ has a positive impact on PEOU. Based on the research findings, implications and limitations are then discussed for future possible research. 相似文献

Today's managers of library journal collection budgets experience pressures from shrinking resource allocations and rising costs. Consequently, they seek ways to assess the value of their collections in relation to user needs. This study at Montana State University seeks to understand what resources users (both faculty and graduate students) are citing in their research, the breadth of the information cited that is provided by the Library, how the Library's proactive and reactive efforts might influence user satisfaction with the information resources provided, and how user perceptions align and differ from information realities. It takes a unique approach by comparing LibQual+® survey results and faculty and graduate student citation behaviors. 相似文献

Due to the growth in both the number and use of e-books, the question arises as to which factors may influence information professionals and library and information science (LIS) students when considering adopting e-books in their organizations. This study uses the technology acceptance model (TAM), a well-known theory for explaining individuals' technology behaviors, and cognitive appraisal theory as theoretical bases from which to predict factors that may influence information professionals and LIS students in their adoption of e-books in their organizations. This study explored two main themes: whether there are differences between information professionals' and LIS students' perspectives towards e-books, and to what extent the TAM, as well as other personal characteristics such as threat, challenge, and motivation, explain information professionals' and LIS students' perspectives. Researchers used questionnaires to gather data on computer competence, attitudes to ebooks, motivation, and cognitive appraisal. Findings reveal that there are major differences between the two groups concerning computer competence, motivation, and challenge. In addition, the TAM, as well as other personal characteristics, can predict the likelihood of e-book adoption, and highlights the importance of individual characteristics when considering technology acceptance. 相似文献

Research data management (RDM) skills are vital yet often untaught in graduate programs, especially in the social sciences. In this article, the authors present a case study of how a research data librarian and an education librarian partnered to provide targeted RDM instruction for a previously unconsidered student group: education doctoral students. They discuss the design, development, and implementation of this focused RDM support. Assessment data from a workshop and in-class sessions are presented and contextualized. From this information, the authors offer practical suggestions that other social science librarians can use to create similar workshops at their institutions. 相似文献

A Comparative Study of Digital Library Use: Factors, Perceived Influences, and Satisfaction 总被引：1，自引：0，他引：1
This study explores the extent to which undergraduate and graduate students in China differ in their digital library use. Unlike the factors promoting digital library use, non-use factors, perceived influences, and degree of satisfaction are quite different between undergraduate and graduate students due to their differing emphases and expectations for information. The implications for digital library services are also discussed. 相似文献
