Abstract

Although hundreds of undergraduate students receive library instruction when their instructors arrange for a class tour or bibliographic instruction session, thousands of other students do not. Describes the planning process that took place in the development of a cross platform interactive multimedia instruction program designed to be accessible to students with diverse information literacy skills. Covers the merits and limitations of several authoring software packages and offers some guidelines concerning time requirements

Abstract

This study details the activities and strategies that 11th grade students with high academic abilities used during their information seeking and use to complete class projects in a Persuasive Speech class. The study took place in a suburban high school in Maryland, and participants included 21 junior honors students, their teacher, and their library media specialist. Each student produced a 5-7-minute speech on a self-chosen topic. Conducted in the framework of qualitative research in a constructivist paradigm (E.G. Guba, & Y.S. Lincoln, 1998), the study used data collected from observations, individual interviews, and documents students produced for their projects - concept maps, paragraphs, outlines, and research journals. Interview and observation data were analyzed using the constant comparative method (B. Glaser & A. Strauss, 1967) with the help of QSR NVivo 2 (QSR International Pty Ltd, 2002); students' documents were analyzed manually. The findings show that students' understanding, strategies, and activities during information seeking and use were interactive and serendipitous and that students learned about their topics as they searched. The research suggests that high school honors students in an information-rich environment are especially confident with learning tasks requiring an exploratory mode of learning.

Abstract

Reports results of an unobtrusive survey of reference services conducted at Central Missouri State University library. The survey was part of a larger assessment of reference seervices and formed a senior level marketing research class adopted as a credit class project. Students were instructed to engage in 2 separate reference transactions and to complete a 14 item survey for each, rating staff service. Following this, the students met on focus groups to discuss their experiences and the library in general. 74% of the reference transactions were rated as 'satisfactory' or 'very satisfactory'. Marketing students were found to be an ideal student group for conducting subjective surveys as they understand the theories and pitfalls of the methodology. Results from the study provides valuable baseline data that will gain more significance when the stufdy is repeated

Abstract

Outlines the role of librarians from ancient times in the preservation of the collective memory, largely for the sake of elite groups. The beginnings of public libraries in Europe during the 1960s and in America during the middle of the 19th century, gave rise to a new literacy among the general population. However, the upsurge in technology threatens to spawn a new class of 'information access illiterate' people. Public libraries can serve the needs of society by giving access to, and providing educational literacy programs for using new technological tools to access information

Abstract

In this paper, we introduce a class of systems called Information Management Assistants (IMAs). IMAs automatically discover related material on behalf of the user by serving as an intermediary between the user and information retrieval systems. IMAs observe users interact with everyday applications and then anticipate their information needs using a model of the task at hand. IMAs then automatically fulfill these needs using the text of the document the user is manipulating and a knowledge of how to form queries to traditional information retrieval systems (e.g., Internet search engines, abstract databases, etc.). IMAs automatically query information systems on behalf of users as well as provide an interface by which the user can pose queries explicitly. Because IMAs are aware of the user's task, they can augment their explicit query with terms representative of the context of this task. In this way, IMAs provide a framework for bringing implicit task context to bear on servicing explicit information requests, significantly reducing ambiguity. IMAs embody a just-in-time information infrastructure in which information is brought to users as they need it, without requiring explicit requests. In this paper, we present our work on an architecture for this class of system, and our progress implementing Watson, a prototype of such a system. Watson observes users in word processing and Web browsing applications and uses a simple model of the user's tasks, knowledge of term importance, and an understanding of query generation to find relevant documents and service explicit queries. We close by discussing our experimental evaluations of the system

Abstract

The article reports a field study investigating the temporality of the information behavior of 44 grade 8 students from initiation to completion of their school inquiry-based history project. The conceptual framework for the study is Kuhlthau's 6-stage information-search process (ISP) model. The objective of the study is to test and extend ISP model concepts. As per other ISP model studies, our study measured the evolution of the feelings, thoughts, and actions of the study participants over the 3-month period of their class project. The unique feature of this study is the unlimited access the researchers had to a real-life history class, resulting in 12 separate measuring periods. We report 2 important findings of the study. First, through factor analysis, we determined 5 factors that define the temporality of completing an inquiry-based project for these grade 8 students. The second main finding is the importance of the students' consultations with their classmates, siblings, parents, and teachers in the construction of the knowledge necessary to complete their project.

Abstract

In a reassessment of Internet usage for reference purposes, data are tabulated from a 1995 class in advanced electronic searching and compared with a previous study from fall 1994. The current data are from 195 searches initiated by students assigned questions on a series of topics: science and technology, medicine and biology, social sciences, arts and humanities, current events, business, legal and government information. The Internet was selected as a viable source 58% of the time and determined to be successful in 86% of theses searches. Although both the selection and success rates differ with the topic being searched and the individual searchers, there is a considerable increase in both Internet selection and success rates from those of the previous year

Abstract

Purpose - The aim of this study is to explore to which extent searching by medical students in Medline produces information items useful for writing an essay measured by precision and relative recall as perceived by the students, the proportion of cited items, and their utilization on four dimensions of the essay writing task evaluated by external assessors. It also aims to study interrelations of search process and outcome. Design/methodology/approach - The study subjects were 42 third year medical students attending a class on Diagnostic and therapy. Searching in Medline was a part of their assignment of essay writing. The data consist of students' printed logs of Medline searches, students' assessments of the usefulness of the references retrieved, a questionnaire concerning the search process, and evaluation scores of the essays given by the teachers of the class. Pearson correlation coefficients were calculated for answering the research questions. Findings - The paper finds that precision and relative recall were not associated with evaluation scores in three of the four dimensions assessed. Some of the process variables were associated with precision and with assessment scores in two of the four dimensions assessed. Citing rate was negatively associated with recall. It seems that precision and recall are only weakly, if at all, associated to the use of information in the documents retrieved for writing the essay. Precision and relative recall are not associated to the way information in the retrieved items is used for performing the task. Users evidently look for a sufficient number of documents containing enough information for progressing in their task. Precision and recall are not sufficient measures in evaluating IR systems, but they have to be completed by other measures indicating the impact of the system on users' task performance. Originality/value - The paper provides useful information on students' information search process.
