Usability testing on library search tools was conducted with ten students and eighteen library staff members at Syracuse University. The study addressed three research questions: (1) Do the ways in which librarians carry out search tasks on the library Web site vary from those of student users?; (2) Are those variations indicative of different mental models, i.e. different experience with and knowledge about the content and search tools on the Web site?; and (3) If there are differences, what are the implications of those different models for the usability of the site by students? Participants were tasked by using the library's Web site to locate both known items and items about a subject in the library's collection. The two groups differed in the success with which they were able to complete the tasks, as well as the time used. There were differences in the selection of search tools, the syntax used within the search box, the expectations of how library resources are organized, and the level of persistence as tasks were performed. Students’ behavior is characteristic of different mental models for how search tools work. The results are applicable to the design of the library's Web site and have implications for how library staff conduct reference and instruction services.  相似文献

This study sought to better understand search performance using an online portal containing a collection of heterogeneous library resources for K-12 students. Search performance is examined in terms of search success, search time, strategy, and effort. This study revealed unsuccessful searches tended to take longer than successful searches; preference of search strategy (searching vs. browsing) did not affect search success outcome; students tended to perform well in tasks for which they were able to use various strategies, and unsuccessful searches tended to use more effort—more mouse clicks, more keystrokes, more queries, more sites visited, and more strategy shifts. Implications of the study are also discussed.  相似文献

ABSTRACT

Can we use the methods of Web usability testing to learn about library instruction? This article is among the first in the field trying to establish a link between usability and instruction. The author discusses useful insights that Web usability can bring to our pedagogy as well as to the efficiency of library instruction. The result of a Web usability study conducted at LaGuardia Community College in 2005 are examined. Findings suggest direct relationships between what is being taught in library instruction sessions and how students browse and search library resources. The author discusses vocabulary test results and draws some parallel with students' success at finding information on the library Web site. Finally, a conceptual model of library instruction assessment through usability studies is presented. The author hopes to provide an innovative approach to library instruction assessment.  相似文献

Abstract

With the transformation of the card catalog into the online public access catalog came the expectation of its increased functionality. For the most part, today's online catalogs perform an expanded list of tasks quite effectively. Bibliographic utilities, system vendors, and individual libraries continue to improve bibliographic retrieval by providing new and better services through the catalog. In spite of these improvements, many observers believe that online catalogs have reached their maturity. Today's information environment includes a wealth of material to which online catalogs cannot provide universal and up-to-date access. Increasingly, librarians are turning to federated searching portal applications to find a means of managing the flood of digital information that threatens to engulf users. This chapter describes essential functionality of such tools, suggesting directions and strategies for improving them. The author concludes that, while the online catalog will continue to function as the principal tool for access control of the library's physical collections, the federated searching portal will ultimately serve as the library's principal Web gateway to digital resources.  相似文献

This paper presents qualitative findings about the search behaviors and research habits of students interviewed at six college and university campuses in the US. Our findings suggest that students’ strategies are influenced by both their non-academic search experiences as well as the broader academic context of their research tasks. Their behaviors suggest an on-going negotiation of these influences, evidenced by the ways they incorporate Google into their research strategy while still closely adhering to faculty instruction for using library resources. Students bring a strong sense of self-reliance to the research process, yet they still experience many barriers and pain points accessing library resources. We have included recommendations for librarians and faculty who, by better understanding the journey of an academic researcher, can work in concert to reduce the barriers and increase the success of students’ research efforts.  相似文献

College students have often been surveyed about their general information seeking behaviors. However, little has been done to explore what specific system features they use to find and save information when they are working on their real-life tasks. In this study, 32 college students were invited to an information interaction lab for a session in which they recalled a recently finished task and worked on a to-be-finished task using a computer in the lab. They were asked to complete questionnaires regarding what systems they used to finish their tasks and what features were helpful for searching and for saving information. Results showed that college students rely more heavily on the Internet sources than on library sources, even for their course related work. The study identified fourteen categories of system features helpful for information search and eight categories helpful for information saving. The findings have implications for designing systems that will better help people accomplish their tasks.  相似文献

Abstract

The MetaLib Library Portal (MetaLib) is a federated search tool that enables simultaneous searching of multiple electronic resources in a single interface and provides links to resources' native interfaces. Many libraries have already implemented this library portal or various components of it. Prior to launching MetaLib at the University of Florida, the authors conducted a usability study to ensure MetaLib features implemented were appropriate for UF's research community. A total of fifteen faculty researchers and graduate and undergraduate students participated in testing and discussing the product during the spring 2006 semester. This paper illustrates the process used to evaluate MetaLib, which included determining a timeline, developing scenario-based and focus group questions, recruiting participants, and conducting usability tests and focus groups. In addition, the authors describe some of the major findings of the study and the solutions recommended in the formal “Usability Test Report for MetaLib,” and provide an analysis of the challenges associated with usability testing of a federated search tool.  相似文献

Abstract

Studies about the assessment of information literacy instruction have reported the use of specific grading criteria, also known as rubrics, to evaluate students’ responses. Rubrics can be divided into two general categories: (1) holistic, where one score is assigned for evaluating the successful completion of a task; and (2) analytic, where a grade is subdivided into discrete components needed to complete the task and each component is given its own score for achievement. This article will investigate which scoring method—employing holistic versus analytic rubrics—is the most effective for evaluating students’ search strategies in terms of providing constructive feedback to students and informing the librarian’s future teaching practices.  相似文献

ABSTRACT

Search engine use is one of the most popular online activities. According to a recent OCLC report, nearly all students start their electronic research using a search engine instead of the library Web site. Instead of viewing search engines as competition, however, librarians at Binghamton University Libraries decided to employ search engine optimization strategies to make their Web site more visible on the search engine result pages. Although search engine optimization is used frequently by commercial Web sites, few libraries have attempted to optimize their own sites. This article describes Binghamton University's experiences in developing and implementing an optimization pilot project. The research presented in this article has importance for libraries who may be considering an optimization project for their own sites.  相似文献

Abstract

Two open source extensions to the Firefox browser, LibX and Zotero, can improve the research process for library staff and users. Once configured and installed, LibX provides Firefox users with an additional browser toolbar and right-click functionality that can search a library's catalog, OpenURL resolver or federated search engine, as well as other Web sites. LibX also includes an autolinking feature, which embeds searchable links within other Web sites such as Google, Amazon, or Yahoo. Zotero merges the best features of other citation management programs with those of popular Web 2.0 services. Zotero users can store full citation information and sort, tag, annotate, and search these citations from within the Firefox browser. Zotero can also “scrape” citations from certain Web sites, allowing users to selectively save citations into their research collection. Zotero can generate complete bibliographies in MLA, APA, and Chicago styles. The abilities to remotely store, synchronize, and share Zotero collections are under development with a planned release date in fall 2007.  相似文献

Physicians are becoming aware of the World Wide Web as a resource for medical information. In spring 1999, first-year students at the University of Louisville's School of Medicine were given an assignment to review and evaluate Internet search engines and directories, medicine-specific search engines and meta lists, and health-related Web sites. Students found that general search engines were easier to learn and use and produced better results than either meta medical sites or medicine-specific search engines. Students were very severe in judging the quality of health-related Web sites. Our students' impressions are compared to those of physicians in similar studies. Solutions to the problems of searching the Web for health information are reviewed.  相似文献

This article summarizes the author's dissertation regarding search strategies of millennial undergraduate students in Web and library online information retrieval systems. Millennials bring a unique set of search characteristics and strategies to their research since they have never known a world without the Web. Through the use of search engines, they have come to expect that searches can be completed using an easy, single search box that produces complete articles on just about any topic. However, the reliability and quality of much of the information on the Web is questionable. Conversely, information that resides in library information retrieval systems is often of high scholarly content, but there is not a single, user-friendly system for millennials to use. A case study investigation was conducted at the State University of New York at Oswego, a public undergraduate university in Central New York. The goal of the study was to identify the search strategies of a sampling of millennial undergraduate students in both Web information retrieval systems and library information retrieval systems in order to expand upon existing theories about millennials and to suggest interface design enhancements, which could make online library information retrieval systems easier for millennials to use. The findings recommend improving database search functionality, such as natural-language searching, spell-checking, and uniform full-text wording and placement. Results also suggested that increasing the availability of full-text articles would contribute to millennials’ use of library information retrieval systems.  相似文献

Library Web sites must compete against easy-to-use sites, such as Google Scholar, Google Books, and Wikipedia, for students’ time and attention. Library Web sites must therefore be designed with aesthetics and user perceptions at the forefront. The Music and Performing Arts Library at Urbana-Champaign's Web site was overcrowded and in much need of a user-focused redesign. This article presents a usability study that compared participants’ use of the old site versus the new site to determine if performance improved on the redesigned site. Participants were asked to complete library-related tasks on both the old Web site and on the redesigned Web site to determine if they could both complete more tasks and complete tasks more quickly on the new site. Participants showed a marked improvement on the new site, and their “think-out-loud” responses to the tasks helped further improve site design and wording. Participants were also surveyed about their perceptions of ease of use and navigation on the old and new sites, and in general, the new site was preferred by participants and seen as a great improvement. Future studies will aim to further involve students and faculty in addressing terminology and site organization.  相似文献

Abstract

The 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

Primo Analytics from two campuses of the California State University system has revealed that a dramatically low proportion of Primo searches originate from mobile devices. The current study focuses on usability concerns as one area that may be preventing students from searching the Primo mobile interface. The sample for this study includes students from two campuses with a variety of experience with library instruction and searching the library’s discovery system. Participants were given the same set of six common academic tasks to complete. Both mobile and desktop participants found three tasks relatively easy to complete. When there were differences in completion rates between the mobile and desktop users, the desktop users were overall more successful. No task was consistently difficult for desktop users to complete, while mobile users found two of the tasks very challenging to complete. Based on the findings, the authors make recommendations for improving the experience of mobile users.  相似文献

Abstract

As the World Wide Web continues to grow, the problem of locating quality resources becomes progressively more acute. While search engines can be invaluable tools for locating certain specific types of information, the technology is more limited in dealing with broad enquiries. This article outlines the development of the BUBL LINK / 5:15 service, which combines powerful browse and search options with a selective approach toresource discoveryand cataloging, and describes how the service overcomes some of the problems in locating Internet resources.  相似文献

ABSTRACT

Adding multiple sources of information in the display of Web search results may negatively affect users’ perceptual experience and information-seeking behavior. This claim was established by investigating the impact of different Web search compositions on users’ ability to extract specific information. In this article, we assumed that the quantity and order of different compositions (areas) in the Web search results page may contribute to individual’s ability to find information relevant to their search queries. An eye-tracking device was used to observe and compare the perceptual behavior of 14 users in an information-seeking task. The results showed that the use of different compositions in the display of Web results page significantly influenced users’ perceptual experience by reducing their attention to the organic results area. The quantity of these compositions was found to greatly increase the cognitive load of users when attempting to retrieve information from the organic area, which negatively affects their information-seeking performance. Our finding provides a rationale for further studies to consider the impact of quantity and order of Web page compositions on individuals’ perceptual attention and cognitive load in information-seeking task settings.  相似文献

ABSTRACT

At Eastern Michigan University, information about library resources and services for Extended Programs (off-campus and online) students was provided in a number of online locations and was sometimes inconsistent and difficult to manage. The library formed an internal task force to evaluate all of the library information and instructional materials provided to Extended Programs students. The task force consolidated key information in one location on the library Web site and collaborated with departments within the library and around campus to provide links from the relevant online locations. This case study describes how Google Analytics was used to assess the use of the revised library Web site and online instructional materials by Extended Programs students. The researchers describe examples of techniques for using Google Analytics and explain how the data collected was used to identify further enhancements to the information provided to Extended Programs students.  相似文献
