Augmented reality (AR) has the potential to fundamentally transform science education by making learning of abstract science ideas tangible and engaging. However, little is known about how students interacted with AR technologies and how these interactions may affect learning performance in science laboratories. This study examined high school…

This study explored relationships between Internet-specific justification beliefs and source evaluation and corroboration during Web search. Fifty university students completed the Internet-Specific Epistemic Justification Inventory (ISEJ), which targeted beliefs concerning the justification of Internet-based knowledge claims about natural science…

Hypertexts include new structural features, such as navigable graphical overviews, that dramatically change the way students interact with texts. Nevertheless, at school students traditionally practice literacy skills appropriate for reading and comprehending printed texts. We explored the possibility that those skills might not be the same as the…

This study examines the cognitive costs of navigation aids in a hypermedia learning task. In a 2(navigable vs. non-navigable) x 2(map vs. content list) experimental design cognitive requirements were measured by users' eye movement data. Additionally, data from users' navigation operations, knowledge acquisition, and subjective evaluation of the…

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…

Explains the development of a classification system for different types of icons to determine which icons proved difficult for elementary school students to read. Considers pictorial, textual, and combination icons from two CD-ROM programs, and concludes that assumptions about pictorial navigation icons and benefits of pop-up labels are probably…

Describes a study of undergraduates that examined the effects of the cognitive load associated with using hypertext linking capabilities in instructional materials. Highlights include cognitive flexibility theory; hypertext navigation; results of criterion measures and regression analysis; and cognitive load theory. (Contains 56 references.) (LRW)

Reviews several mechanisms to support navigation in hypertext following a brief discussion of the phenomena of disorientation in hyperspace. Categorizes ways to support navigation in terms of the following: solutions regarding the tools to support navigation; solutions regarding interface and navigation metaphors; and solutions regarding hardware…

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)

Describes a study of fifth graders that examined the effects of learner control and navigational aids on performance in a hypermedia instructional program. Results indicated that students who moved freely within the program and had access to navigational aids, interacted more with the program and achieved higher performance on posttests.…

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"…

Outlines important issues to consider when analyzing navigation in hypertext. Identifies internal and external factors of learning and information seeking with hypertext, and presents a summary of related research. Addresses different criteria for analyzing navigation patterns and focuses on the shortcomings of present studies. (AEF)

Videotaped observations were made of seventh and eleventh grade students using an instructional hypermedia system. Three profiles of hypermedia navigation emerged with each style characterized by distinct information processing strategies. Analysis of the characteristics of learners revealed that students within each profile group had similar…

Describes a study of university students that examined the influences of navigation in hypertext learning environments and discusses advantages and disadvantages of hypertext as instructional media. Discusses active (self-directed) versus passive (pre-sequenced) access; knowledge acquisition; emotional outcomes; and knowledge utilization with a…

Presents an exploratory study of a Web-based distance education course at an Australian university. Identifies factors associated with teaching effectiveness in online delivery: the technology used, including ease of access, navigation, interaction, and interface; instructor characteristics; and student characteristics, including previous use of…
