In late October 1967, the USS Scorpion was lost at sea, somewhere between the Azores and Norfolk Virginia. Dr. Craven of the U.S. Navy's Special Projects Division is credited with using Bayesian Search Theory to locate the submarine. Bayesian Search Theory is a straightforward and interesting application of Bayes' theorem which involves searching…

This study is a third in a series of studies that examined students' information seeking and problem solving behaviors while interacting with one of two types of web-based representations of an ill-structured instructional design case: hierarchical (tree-like) and heterarchical (network-like). A Java program was used to track students' hypermedia…

This study employed a 2x2 (Generative Activities by Navigational Activities) post-test only research design in examining learning while using a hypertext system in a linear, navigational, linear generative, or navigational generative format. Participants were 43 undergraduate students. In the first experiment, participants were assigned to one of…

An empirical study was carried out to explore effects of three sets of schedules developed by Edgar Stones as guidelines conducive to student learning. Guidelines for concept teaching, psychomotor skill development, and teaching problem solving formed the instructional framework for teaching 11-year-old children the principles of navigational…

Describes three experiments that examined college students' self-determination, problem-solving, and reading comprehension when using a linear, navigational, or generative computerized system to solve a problem or to prepare for a reading-comprehension test. Suggests that understanding students' goals explains outcomes of instruction, effects of…

This study investigated the effects of instructionist (navigational, functional) versus constructionist (adaptive) World Wide Web (WWW) site environments on collaboration, achievement, attitudes, and perceived level of learner controls reported by students after working in cooperative dyads within the different types of Web-based learning…
