Pathfinder is a graphic theoretic technique used to analyze proximity data. This study evaluates its validity: (1) for representing and comparing individuals' navigation through a computer-based hypermedia environment; and (2) for generating an empirically-derived path that represents a set of individual navigational paths during computer-assisted…

Describes a study that explored the use of log files to investigate the process of hypermedia navigation at the University of Connecticut's information kiosk. Highlights include the use of cluster analysis; four different types of navigational performance; and external validation criteria, including self-efficacy, perceived utility, and interest.…

Anchored instruction calls for the establishment of a macrocontext to "anchor" instruction within a realistic situation. Evidence is provided that video anchors encourage students to adopt certain contrived goals over their more naturalistic goals. Suggests that goals that enable the problem solver to detect the "raison d'etre"…

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…

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…
