Presents an overview of the university fleet, its purpose, relationship to the rest of the United States oceanographic research fleet, history, cost factors, and other information. (DC)

A study of 170 undergraduates at the University of Washington examined the effect of terminology and screen layout on student ability to select databases from an initial online interface, "Session Manager." Results indicated that student ability to navigate menu screens was improved with expanded terminology and type grouping of online…

Describes the successive stages of the School of Aeronautical Engineering of Madrid, Spain, in terms of entry requirements, curricula guidelines, options or specialties, duration of studies, and number of graduates. Also includes a description of the Spanish aeronautical industry and its evolution. (Author/PVD)

Discusses when librarians should develop their own Internet collections and how to add value to them, based on examples from the Argus Clearinghouse Web site. Topics include evaluation criteria for Internet resources; strategic planning; Internet collection development policies; and adding value through organization, navigation, learning systems,…

Describes the Online Academy that developed online instructional modules in reading, positive behavior support, and technology across the curriculum for preservice teacher education programs at the University of Kansas. Focuses on the formative evaluation processes that were employed in creating the instructional design, usability, and…

Describes the visualization of a navigation classification scheme in an information retrieval (IR) system. Highlights include Charles Cutter's rules for creating a dictionary catalog; user needs; an example of undergraduate research using this scheme; and user interaction with the IR system. (Contains 64 references.) (Author/LRW)

This discussion of hypertext focuses on a study of undergraduates that explored the conditions for making hypertext a better environment than a traditional linear text for studying and for an information search. Highlights include the influence of students' learning styles; and the availability of navigation tools. (Author/LRW)

A study of 22 high school students who used a prototype navigational map for browsing hypermedia documents found that the tool was not effective. Supporting previous research the study found the use of maps resulted in poorer performance, less use of the system, lower perceived control, and poorer development of mental representations. (PEN)

Twelve orienteers and four military scouts each described a critical incident requiring navigation skills in off-road terrain. Interview analysis generated a taxonomy of the navigator's cognitive model encompassing perception and use of environmental cues, problem-solving and decision-making strategies, and skill level. Contains 38 references. (SV)

Describes a study that investigated the effects of visual control (self-controlled versus system-controlled) and gender difference on learning with scientific multimedia instruction, observed how boys and girls differed in navigating and processing visual information in a hypermedia environment, and examined how visual control influenced learning.…

Reports on a conference workshop that addressed Visual Information Retrieval Interfaces (VIRIs). Topics include evaluation methods; task dimension for evaluating VIRIs; efforts to fund European development of VIRIs; metrics, including cosine vector; navigation among documents; and interactions with users. (LRW)

Describes a study of college freshmen that investigated the effects of navigation maps on search performance, browsing behavior, and cognitive map development within hierarchical-structured hypertext courseware. Results of analysis of variance indicate that map type significantly affected search performance and browsing behavior. (Author/LRW)
