Research shows that students face a range of difficulties when using the Internet to solve information problems. Using a quasi-experimental design, we tested a strategy to improve Chilean 10th graders' skills for information problem solving using the Internet (IPS-I). The intervention was based on a workshop in which students learned IPS-I…

With the near-overload of online information, it is necessary to equip our students with the skills necessary to deal with Information Problem Solving (IPS). This study also intended to help students develop major IPS strategies with the assistance of an instructor's scaffolding in a designed IPS course as well as on an Online Information…

Image searches are now crucial for obtaining information, constructing knowledge, and building successful educational outcomes. We investigated how reading ability and Internet experience influence keyword-based image search behaviors and performance. We categorized 58 junior-high-school students into four groups of high/low reading ability and…

This paper deals with two types of logical problems--recognition problems and reverse engineering problems, and with the interrelations between these types of problems. The recognition problems are modeled in the form of a visual representation of various objects in a common pattern, with a composition of represented objects in the pattern.…

For the forty-third time, the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented online during the annual AECT Convention. Volume 1 contains 37 papers dealing primarily with research and development topics. Papers dealing with the…

The study of this dissertation provides a solution to a very specific problem instance in the area of data mining, data warehousing, and service-oriented architecture in publishing and newspaper industries. The research question focuses on the integration of data mining and data warehousing. The research problem focuses on the development of…

Analyzes certain features of work tasks and relates these features to types of information people are looking for and using in their tasks, patterning of search strategies for obtaining information and relevance assessments in choosing retrieved documents. The major claim is that these information activities are systematically connected to task…

Explores the use of metaphors as problem-solving mechanisms by novice searchers of bibliographic databases. Subjects were 28 undergraduate students at the University of Technology, Sydney, Australia, who "talked through" a search on a bibliographic retrieval system. A range of metaphors was apparent from the language used by students.…

The Information Search Language (ISL), described in this report, is a problem-oriented language designed to facilitate the manipulation of real character strings with the Control Data 1604 computer. The report gives instructions for the language; these may be classified as Pseudo-ops, Word-Oriented instructions, Character-string instructions,…

Electronic databases have grown tremendously in both number and popularity since their development during the 1960s. Access to electronic databases in academic libraries was originally offered primarily through mediated search services by trained librarians; however, the advent of CD-ROM and end-user interfaces for online databases has shifted the…

Discusses the relationship between personal knowledge in a domain and online searching proficiency in that domain, and the relationship between searching proficiency and database-assisted problem-solving performance based on a study of medical students. Search results, selection of terms, and efficiency were found to be related to problem-solving…

Explores the relationship between the concept of uncertainty in information seeking within a model of the problem-solving process and variables derived from other models, based on longitudinal data collected in the United Sates and the United Kingdom that investigated the processes of mediated information retrieval searching during human…

Examines the effects of database assistance on clinical problem solving across three cohorts of medical students and two database interfaces. Discusses the relationship between personal domain knowledge and problem solving, personal domain knowledge and database searching, and comparisons of different interface styles in information retrieval…

Presents the theoretical framework and research design of a project based on longitudinal data collected in the United Sates and the United Kingdom that investigated the processes of mediated information retrieval searching during human information-seeking processes. Topics include problem-solving; uncertainty; cognitive styles; and…

The concept of a hierarchy of evidence is useful in rapid electronic searching to answer questions arising during the natural course of clinical practice. The answerable question often begins "What is the evidence that ..." and, when focused on a treatment, usually includes a population, an intervention, a comparison group, and an outcome, often…
