Abstract

Reports on a study at an elementary school in Washington, DC examining pupils' use of an OPAC. Presents this within the overall instructional environment of the school in order to open a window on the broader interaction of children, technology, curriculum, instruction and learning. Explains the methodology used in the study, the findings of the study, and notes a number of conclusions. Focuses in particular on the patterns of success and failure of children's use of the OPAC, their search strategies and the nature of their interaction with the OPAC

Abstract

Tang and Solomon, based upon their review of the history of topical and other than topical criteria in relevance evaluation, decide to look at a two stage model where judgements are first made on surrogate records and then on full document text to determine if a criteria shift takes place and if so in what manner and to what degree. Both a controlled experiment and a naturalistic study were used to study the staging of relevance judgement criteria. In the controlled environment 90 undergraduate Psychology students were instructed to choose papers that would help them meet an assignment from 20 preselected papers on broader topic that included that assigned. They first selected on the basis of citation and abstract, then read the papers, and in each process filled out a questionnaire on the importance of each of 15 criteria at each stage of the two-stage process. In the naturalistic study 9 Ph.D. Psychology students conducted literature searches to support their own research and were asked to think aloud while making their decisions from retrieved surrogates, and later filled out a questionnaire while reading those materials that they selected and then interviewed at the end of the process. Apparently understandability is important at both stages. Importance increased at stage two. Cognitive criteria do not all follow the same pattern across stages. The controlled group thought quality of information was most important in stage one and topicality most important in stage 2. In the naturalistic study topicality was most frequent for stage one and research structure for stage two. A classification of criteria by their functionality is suggested as a better approach. First a division as to whether a criterion is objectively associated with the document as opposed to being subjectively associated with a person's expectations; then a division based on primary (essential) or secondary (for assistance) status.

Abstract

Reports on a study of children's intentions, purposes, search terms, strategies, successes and breakdowns in accessing fiction. Data was gathered using naturalistic methods of persistent, intensive observation and questioning with children in several school library media centres in the USA, including 997 OPAC transactions. Analyzes the data and highlights aspects of the broader context of the system which may help in development of mechanisms for electronic access

Abstract

This article reports research that explored children's information retrieval behavior using an OPAC in an elementary school library. The study considers the impact of a variety of factors including user characteristics, the school setting, interface usability, and information access features on children's information retrieval success and breakdown. The study reports the overall patterns of children's behavior that influence success and breakdown in information retrieval as well as findings about the intentions, moves, plans, strategies, and search terms of children in grades one through six

Abstract

Explores the variety of user behaviour exhibited by users of information retrieval systems over time and the effort of differences between expert and novice searchers on an understanding of information searching dynamics and on the design of information systems. Based on a naturalistic case study. Points out some of the dynamic patterns of behaviour of children's use of online catalogues (OPACs)
