Interactive learning environments (ILEs) are increasingly used to support and enhance instruction and learning experiences. ILEs maintain and display information, allowing learners to interact with this information. One important method of interacting with information is navigation. Often, learners are required to navigate through the information…

This study sought to better understand search performance using an online portal containing a collection of heterogeneous library resources for K-12 students. Search performance is examined in terms of search success, search time, strategy, and effort. This study revealed unsuccessful searches tended to take longer than successful searches;…

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…

Williams syndrome (WS) is a genetic disorder associated with severe visuocognitive impairment. Individuals with WS also report difficulties with everyday wayfinding. To study the development of body-, environment-, and object-based spatial frames of reference in WS, we tested 45 children and adults with WS on a search task in which the participant…

Delaware Technical and Community College online courses are not properly focused to ensure instructors are effective in improving student achievement. First time online students are not given the proper tools when navigating online courses at the college. The focus at Delaware Tech should be on improving the format which students use when…

This article presents the text of the author's presidential address, delivered at the National Council of Teachers of English (NCTE) Annual Convention in Philadelphia, Pennsylvania, on November 22, 2009. For the author, the title of this president's address, "Sailing over the Edge: Navigating the Uncharted Waters of a World Gone Flat," calls to…

Field instruction is a critical piece of undergraduate geoscience majors' education, and fieldwork remains a major part of the work of professional geologists. Despite the central importance of field education, there exists relatively little educational research exploring how students learn to solve problems in geological fieldwork. This study…

This textbook is a course in elementary surveying. It has been the intention of the author to begin with the very elements of the subject, and to combine those elements in the simplest manner, so as to render the higher branches of plane-surveying comparatively easy. All the instruments needed for plotting have been carefully described; and the…

Research on neural networks and hippocampal function demonstrating how mammals construct mental maps and develop navigation strategies is being used to create Intelligent Autonomous Mobile Robots (IAMRs). Such robots are able to recognize landmarks and navigate without "vision." (SK)

Offers a redefining of three problem areas associated with the cognitive effects of the semiotic characteristics of hypermedia: hypertext associativity, non-linearity, and the rapprochement of real and hypertext navigation. Focuses on navigation and discusses characteristics of hypermedia and its rapport with knowledge. (Author/LRW)

Three hosted federated search tools, Follett One Search, Gale PowerSearch Plus, and WebFeat Express, were configured and implemented in a school library. Databases from five vendors and the OPAC were systematically searched. Federated search results were compared with each other and to the results of the same searches in the database's native…

This study investigates the relationships between the use of a zoom tool, the terms they supply to describe the image, and the type of image being viewed. Participants were assigned to two groups, one with access to the tool and one without, and were asked to supply terms to describe forty images, divided into four categories: landscape, portrait,…

Imagine soaring in the Earth's atmosphere to near the edge of space. Is there air to breathe? Is it dark? Are there clouds? What about air pressure? Fifth-grade students from Ferguson Elementary in Klamath Falls, Oregon, were wondering these questions as they participated in "To the Edge of Space," an exciting, yearlong collaborative…

Sound provides and offers amazing insights into the world. Sound waves may be defined as mechanical energy that moves through air or other medium as a longitudinal wave and consists of pressure fluctuations. Humans and animals alike use sound as a means of communication and a tool for survival. Mammals, such as bats, use ultrasonic sound waves to…

With the widespread availability of Internet and computer technology, on-line web-based learning has become prevalent in the field of teaching Chinese as a second/foreign language (CSL/CFL). This study examined the concepts of usability and types of design elements that help construct an effective web-based learning environment, as well as their…
