A study evaluated the process of training teachers to use an interactive multimedia package for classroom instruction in ecology. Ways in which teachers assessed relevant printed text and hypertext information were mapped and analyzed. Search patterns were classified into two cognitive strategies (sequential, goal oriented). Sequential strategies…

A study investigated the effectiveness of combined lecture and computer demonstration to train third-year pharmacy students (n=48) in computerized information retrieval. Results show the method to be effective in helping students translate Boolean logic into search strategies. The importance of improving pharmacy students' literature retrieval…

Reports on a collaboration between academic teaching staff who coordinate an undergraduate foundation course in computers and society at the University of South Australia. Highlights include information literacy and lifelong learning; the combination of face-to-face and online instruction; links from the portal; student assessment; search…

British and American information science textbooks present keyword and controlled vocabulary searching in different ways, and put differing emphases on the use of variant spellings and word variations. This reflects the differing ways that information professionals prepare online search strategies. Differences may reflect occupational trends,…

Presents longitudinal case studies of four students in high school and after completion of college to compare their perceptions of the information search process in libraries. Library user studies are discussed, a model of the search process is described, and implications for the design of information systems are suggested. (36 references) (LRW)

Describes a study that used a mental models perspective to examine the search behaviors of gifted elementary school children searching a full text electronic encyclopedia. The discussion covers analyses of search patterns used, differences between younger and older searchers, suggestions for systems design, and needed further research. (39…

Discusses the need for library science to examine users' search behaviors in the context of social cognition and creative problem solving. Topics covered include the psychology of search behavior, problem solving approaches to library instruction in online searching, and problem solving protocols. (29 references) (CLB)

Discussion of precision in information retrieval highlights a prototype online catalog, ILSA (Improving Library Subject Access), developed at Indiana University of Pennsylvania that uses subject clusters and classification. Topics addressed include problems with keyword searching, controlled vocabulary, and thesauri; natural language mapping…

Discusses ways in which academic and public librarians can provide help with multicultural and international topics in spite of unhelpful subject headings and weak collections, including an awareness of cultural bias; collection policies to support diversity; relearning the collections and access strategies; and restructuring reference searches.…

Describes a task-oriented assessment of two MEDLINE searching systems by medical students, one using Boolean searching on human-indexed thesaurus terms and one using natural language searching on words in the title, abstract, and indexing terms. Highlights include user certainty in answering questions, time needed, and user satisfaction.…

Discusses information retrieval and the future of databases in education, examines problem-solving strategies, and describes a study of undergraduate students that compared the use of a traditional textbook with the use of the electronic version on CD-ROM. Performance on tests and strategies used to answer questions are analyzed. (20 references)…

Discusses the incorporation of CD-ROM technology into Georgia State University's William Russell Pullen Library, and considers its impact on reference services and bibliographic instruction. Concludes that technology increases the need for critical thinking skills, faculty-librarian interaction, and human resources for reference and technical…

Discusses a decline in patron requests for librarian-mediated searches of MEDLINE at Yale University's medical library and describes results of a survey that was conducted to determine possible reasons. The influences of miniMEDLINE (an in-house version), online end-user systems, and CD-ROMs outside the library are examined. (five references) (LRW)

Describes a study that compared two information retrieval systems on a full-text medical database: one featured concept-based automatic indexing and statistical retrieval techniques, and the second used traditional word-based Boolean techniques. Evaluation of search results by calculating relative recall and precision is discussed, and user…

Describes the continuing development of a bibliographic instruction (BI) course at Carleton College for a sociology/anthropology research methods course that focuses on statistical sources. Goals and objectives of the course are explained, and various methods of teaching search strategies are described, including overhead transparencies, handouts,…
