Since 2007 the author has been teaching a hybrid Information Literacy course at Lakeview High School in Battle Creek, Michigan. It combines an online information literacy focus with real-world library work experience in her media center. This blended course has just been revised so that high school graduates will be able to fulfill Michigan's…

When examined across studies and fields, navigation research is fragmented and inconsistent. In this article, we argue that this is the result of navigation research having generally been conducted without guidance from an overarching theoretical framework. In order to illustrate our position, we have included results from a very simple…

This paper discusses the complexity of explanation activity in human-human goal-directed dialogue and suggests that this complexity ought to be taken into account in the design of explanation in human-computer interaction. A general model of clarity in human-computer systems is proposed, incorporating explanation as one component. On the basis of…

Discusses end-user searching in Boolean information retrieval systems considers the role of search intermediaries and proposes a model of user preferences that incorporates a user's profile. Highlights include document representation; information queries; document output ranking; calculating user profiles; and selecting documents for a local…

Explores the fundamentals of browsing behavior as a basis for the creation of an intelligent computer system to assist in online information retrieval. A prototype system is described, and the results of initial tests are reported. (5 references) (Author/CLB)

Compares traditional online interview with the presearch counseling session (process whereby a librarian, acting in an advisory role, assists client searcher in devising his/her search strategy, before that searcher goes online) and presents a one-step model of a presearch counseling session. An online self-service worksheet and 102-item…

Discusses use of associative search techniques and theoretical approaches to document retrieval problems contrasting two different ways of improving system performance: appending associative search techniques to conventional document retrieval systems and designing document retrieval systems based on probabilistic design principles. Four…

Examines various ways of dividing the labor of an information search between the person and the system. Different configurations of two dimensions--degree of system involvement in searching and types of search activity carried out by the person or system--are discussed. Recommendations for further research and development are offered. (49…

Discusses term weighting formulae and their use for selecting new terms to enhance a search statement and for weighting the terms for retrieval purposes once selected. The Swets model of information retrieval system performance is described, an approach to term selection is presented, and future research is suggested. (five references) (LRW)

Offered as an alternative to the search strategy model for bibliographic instruction, the approach to library instruction in psychology which is described involves analysis of the natural structure of the research literature. An example using Festinger's theory of cognitive dissonance is presented. Twelve references are cited. (EJS)

Presents a general model of the information-seeking process. Various aspects of information-seeking behavior are projected over an organizational and behavioral framework; three dimensions of information-seeking behavior are described, i.e., the conditions, the context, and the process; interactions among these dimensions are considered; and…

Examines historical and current difficulties in information retrieval, including the tendency of technology, because of the problems of scale and distribution, to make information invisible to users. Attempts to organize networked resources are described, and serendipity is proposed as a model for future retrieval. (two references) (MES)

Discussion of positivist and interpretive approaches to research and postpositivism focuses on two studies that apply interpretive research in different ways: an exploratory study of user-developed computing applications conducted prior to a positivist study and a study of end-user searching behaviors conducted concurrently with a positivist…

Advocates the integration of online instruction into business school curriculums and presents a curricular model that has evolved from author's experiences--introductory lecture, group planning and development on online search strategy, group online searching. Instructor training, required equipment, and databases and costs are considered. Three…

Discusses approaches to the integration of query-based information retrieval and browsing in a hypertext network. A prototype system developed to evaluate the proposed approach in terms of retrieval effectiveness and search efficiency is presented, and design and implementation issues concerning the prototype are considered.
