A historical fact is like a fata morgana, "always less than what really happened." Even consensus does not establish truth; otherwise history is merely the version of the past that people agree to accept. The students who participated in the acclaimed 5th Street Cemetery Necrogeographical Study innocently found themselves clashing with…

One of the major features of a computer based instruction (CBI) is its non-linear structure allowing learners the opportunity of flexible navigation to accommodate their own needs. However, this non-linear structure may cause problems such as inefficient navigation, being lost or cognitive overhead for some learners. The aim of this study is to…

The purpose of this publication is to promote a better understanding of how basic weather features develop on Chesapeake Bay and enable boaters to enjoy the Bay's unique waterways. Sections include: (1) Chesapeake Bay climate; (2) general weather features; (3) seasonal trends; (4) sources of weather information and forecasts; (5) weather service…

This report documents the training effectiveness of a map interpretation and terrain analysis course (MITAC) developed to enhance the ability of helicopter pilots to navigate accurately during low altitude terrain following flight. A study comparing student aviators taught by the MITAC technique with a control group of students taught by…

The report describes the math model for an experimental ship handling trainer. The training task is that of a replenishment operation at sea. The model includes equations for ship dynamics of a destroyer, propeller-engine response times, ship separation, interaction effects between supply ship and destroyer, and outputs to a visual display system.…

This book, which can be used only in the Air Force ROTC program, elucidates ideas about air navigation techniques. The book is divided into two main parts. The first part describes the earth's surface and different components of navigation. A chapter on charts provides ideas about different kinds of charts and a variety of symbols used in…

Copernicus remains the symbol of the scientist who felt responsibility for the possible conquences of his discoveries and who valued free thought and scientific truth. (Author)

Several logical methods for dividing circles and time into legitimate metric increments are examined and discussed as being convenient for conducting business, doing mathematics, navigating, and scheduling our daily lives. (MP)

Almost without exception, published studies on cognition in orienteering have adopted an information processing perspective involving dualism between objective and subjective worlds. An alternative, experiential framework focuses on the orienteer's conception of (or way of experiencing) the task to be accomplished, and on "affordances" (lines of…

Discusses how to make the best use of the Internet and develop effective Web sites based on an architectural analogy. Highlights include new possibilities for collaboration and community building, goals for using technology, successfully introducing change, navigation issues, and the need to create new models instead of replicating old ones. (LRW)

Explains adaptive hypermedia, provides a brief overview of adaptive navigation support techniques in educational hypermedia systems, and analyzes the results of most representative empirical studies. Demonstrates the importance of context and knowledge levels of the users and suggests that meta-adaptive hypermedia systems should be the next step.…

Discusses the rapid growth of the World Wide Web and the lack of use of electronic books and suggests that specialized contents and device independence can make Web-based books compete with print. Topics include enhancing the hypertext model of XML; client-side adaptation, including browsers and navigation; and semantic modeling. (Author/LRW)

Describes the design of an online exhibit about the history of the United Farm Workers union that was created on the World Wide Web by the Walter P. Reuther Library/Archives of Labor and Urban History. Discusses Web design, hypertext links, and ease of navigation. (Author/LRW)

Navigation exercises in the outdoors involve interactive team skills; individual assessment of self-confidence, competence, and esteem; and leadership skills. Learning goals include planning, managing a team, handling information, allocating individual objectives, making decisions, and attending to accuracy. Provides facilitators with instructions…

Discussion of navigation buttons in instructional hypermedia programs focuses on a study of college students that investigated the effectiveness of buttons with pictorial representations, buttons with text and pictorial representations, and buttons with text only. Findings indicate that buttons with text labels reduce user confusion concerning…
