Abstract

It is important for education in computer science and information systems to keep up to date with the latest development in technology. With the rapid development of the Internet and the Web, many schools have included Internet-related technologies, such as Web search engines and e-commerce, as part of their curricula. Previous research has shown that it is effective to use search engine development tools to facilitate students' learning. However, the effectiveness of these tools in the classroom has not been evaluated. In this article, we review the design of three search engine development tools, SpidersRUs, Greenstone, and Alkaline, followed by an evaluation study that compared the three tools in the classroom. In the study, 33 students were divided into 13 groups and each group used the three tools to develop three independent search engines in a class project. Our evaluation results showed that SpidersRUs performed better than the two other tools in overall satisfaction and the level of knowledge gained in their learning experience when using the tools for a class project on Internet applications development.

Abstract

Cataloging remains a fundamental component of library and information science and has many lessons to teach the architects of the Internet age. All students can benefit from taking a cataloging course, especially if it stresses cataloging as one specific answer to the problems of managing information and places cataloging within a larger context that also includes indexing and Internet search engines. Students deserve cataloging courses that combine theory and practice, avoid memorization, and require them to show a mastery of core principles rather than picky details. This paper includes specific suggestions on how to make cataloging exciting.

Abstract

Online searching was once the province of professional search intermediaries who had received formal training in information retrieval (IR). Today's searchers no longer fit a standard profile, ranging from school-age children to retirees, the majority of whom have received no training in search. While entering a simple query to a commercial Web search engine may not require any specialized skills, a basic understanding of the search process and successful search techniques and strategies, particularly for nontrivial queries, can result in more productive searches and a more enjoyable search experience. Despite recognition of the growing need for search training that supports the cognitive processes and learning styles of individual searchers, there has been relatively little response from the academic community to date. In this chapter, we review the existing literature on search training. We also propose the development of a search training framework based on models of the search process, research on search errors, and models, methods and approaches gathered from research on training and learning within other, related disciplines.

Abstract

Purpose This paper investigates how school teachers look for informational texts for their classrooms. Access to current, varied and authentic informational texts improves learning outcomes for K-12 students, but many teachers lack resources to expand and update readings. The Web offers freely available resources, but finding suitable ones is time-consuming. This research lays the groundwork for building tools to ease that burden. Design/methodology/approach This paper reports qualitative findings from a study in two stages: (1) a set of semistructured interviews, based on the critical incident technique, eliciting teachers' information-seeking practices and challenges; and (2) observations of teachers using a prototype teaching-oriented news search tool under a think-aloud protocol. Findings Teachers articulated different objectives and ways of using readings in their classrooms, goals and self-reported practices varied by experience level. Teachers struggled to formulate queries that are likely to return readings on specific course topics, instead searching directly for abstract topics. Experience differences did not translate into observable differences in search skill or success in the lab study. Originality/value There is limited work on teachers' information-seeking practices, particularly on how teachers look for texts for classroom use. This paper describes how teachers look for information in this context, setting the stage for future development and research on how to support this use case. Understanding and supporting teachers looking for information is a rich area for future research, due to the complexity of the information need and the fact that teachers are not looking for information for themselves.

Abstract

This paper desctibes a study of undergraduate student search behavlour, examines the results through the lens of various disciplines, and provides now insights that will increase our understanding and facilitate the development of mom effetive instructional programmes Perspectives and research results drawn from multiple disciplines are used to explore the role of mental modele, reference groups and habits, and IntelIectual development in the search behaviour demonstrated by the undergraduate students. During interviews conducted as part of the study, many students were able to articulate the importance of source evaluation and describe electronically-appropriate methods for assessing the authority and reliability of Weh based information resources. In practice, however, these students frequently abandoned source evaluation altogether and, following the path of Ieast resistance, relied exclusively on basic Google searching, This approach both compromiscd the quality of their search results and contributed to frustration with the research process. This may not be extraordinarily unusual behaviour, but it is cause for considerable concern among Information literacy programme planners and Instructors. Discussion of the study results and related research is followed by pragmatic suggestions for modifylng ineffective search behaviour through emhanced instructional programmes

Abstract

Considers student apprehension when encountering new information technologies and proposess a variety of active learning exercises within the framework of 4 questions that it is suggested researchers in the virtual library should be taught when learning how to search electronic sources: where am I? How do I do it? What am I trying to do? and What do I do with it?. Also details the use of student journals as an effective tool for gauging student learning and encouraging critical thinking

Abstract

Scholars writing books that are widely used to support teaching in higher education may be undervalued because of a lack of evidence of teaching value. Although sales data may give credible evidence for textbooks, these data may poorly reflect educational uses of other types of books. As an alternative, this article proposes a method to search automatically for mentions of books in online academic course syllabi based on Bing searches for syllabi mentioning a given book, filtering out false matches through an extensive set of rules. The method had an accuracy of over 90% based on manual checks of a sample of 2,600 results from the initial Bing searches. Over one third of about 14,000 monographs checked had one or more academic syllabus mention, with more in the arts and humanities (56%) and social sciences (52%). Low but significant correlations between syllabus mentions and citations across most fields, except the social sciences, suggest that books tend to have different levels of impact for teaching and research. In conclusion, the automatic syllabus search method gives a new way to estimate the educational utility of books in a way that sales data and citation counts cannot.

Abstract

Describes the rethinking and revision of a course on online searching, at Michigan University, brought about by the proliferation of information services and interface available online. The course now focuses much more on the concepts underlying information searching and their interrelationships, exposes students to a wider variety of information services while still allowing them to develop skills on 1 specific system, and asks students to ne reflective regarding their own searching as well as the environment. The aim of this new version is to help students understand what expert searchers know about searching, their wisdom, by talking about more than file structures and search languages

Abstract

Presents the results of a survey conducted to investigate how library and information science students are being educated for careers in a changing reference/information environment. A review of the literature on education for reference work since the 1970s shows a shift in focus from reference sources to reference work with a greater emphasis on user needs and behaviour. Completed questionnaires from 48 teachers of basic reference courses in ALA-accredited programmes were analyzed quantitatively and qualitatively. The most frequently taught skills related to the reference interview and search strategy, most courses covered types of reference sources as well as specific titles, and most teachers give some attention to reference/information services. The learning objectives and teaching methods exhibited considerable variety, however. Qualitative analysis of data about course content and future trends suggested a growing recognition of the systematic nature of reference work and the importance of evaluation

Abstract

This two-part study investigates the effect of a 30minute presentation of Carol Kuhlthau's Information Search Process (ISP) model on students' perceptions of research and research paper anxiety. An experiment was designed to collect both quantitative and qualitative data during a semester. An upper division undergraduate course, Technical and Professional Writing, with four sections participated in the experiment in fall 1999. A survey instrument, the Research Process Survey (RPS), was developed to collect data about students' feelings and thoughts at the onset of their course research project (pretest) and at the completion of the project (posttest). A standard anxiety test (STAI Y-1) was adopted to measure anxiety levels during pretest and posttest sessions and at two additional points between. Two of the four sections heard a guest presentation of the ISP model as treatment after the pretest; the other two sections heard a different guest speak about career experiences as a technical writer (a placebo talk). The results of this experiment are reported in two articles according to the nature of the collected data. This article reports on results of the quantitative analysis. Four hypotheses were proposed to examine the effects on awareness of cognitive aspects, awareness of affective aspects, level of anxiety, and satisfaction with research. One hypothesis was supported. A significant change in anxiety levels was measured (p = 0.5). Although statistical tests did not reject three null hypotheses, positive trends in change as a result of the ISP model were identified. A second article reports on results of qualitative analysis of the texts that participants wrote about a memorable past research experience and about the current research experience.

Abstract

This is Part II of an experimental study investigating students' perceptions of research and research paper anxiety. The study integrates quantitative and qualitative designs to collect complimentary data. The participants were students in four sections of an upper division undergraduate course on technical and professional writing during the fall of 1999. A survey instrument used the Critical Incident Technique to solicit writings in students' own words about a memorable past research and writing experience at the beginning of the semester and the current research and writing at the end of the semester. The quantitative part of the survey measured students' perceptions about research using a questionnaire with five-point Likert scale, and students' anxiety levels using a standard state anxiety test (STAI Y-1). The first article, Part 1, provides a detailed description of the experimental design and reports on quantitative results. This article reports on content analysis of students' writings about their experiences of the two research projects. Analysis of the data confirmed Kuhlthau's Information Search Process (ISP) model and revealed additional affective and cognitive aspects related to research and writing.
