Hypertext researchers and designers contend that the hypertext information structures may reflect the semantic structures of human memory. Further, they believe that mapping the semantic structure of an expert onto hypertext information structure and explicitly illustrating that structure in the hypertext will result in improved comprehension…

To alleviate the staffing pressures of increased demands for tours and classes at the Duane G. Meyer Library, Southwest Missouri State University, two HyperCard programs were developed--a library instruction text and a library orientation tour. A study of the relative effectiveness of the HyperCard text with paper texts for bibliographic…

Describes the development and installation of a hypermedia system for student use at the University of Texas Pan-American library that provides information about the library's resources as an alternative to existing printed materials. Highlights include selecting an authoring tool and computer hardware and the development of an icon-based system.…

This study was conducted to test the effect of learning styles and instructional advisement on subjects' achievement test performance, frequency in viewing embedded, elaborated information, time on task, and frequency in receiving instructional advisement in a hypermedia instructional system. In the first of two sessions, a screening test was…

Discussion of the use of hypertext focuses on a study conducted at the University of Connecticut that evaluated the effectiveness and acceptance of a hypertext document under one of three different learning conditions: (1) in competition with standard lectures, (2) as a supplement to lectures, and (3) as a replacement for lectures. (14 references)…

Describes a study of Australian undergraduates that investigated the nature of learning experiences and quality of learning achieved when students organized information into a HyperCard program. Differences between the learning strategies of using HyperCard and traditional class tutorial presentations are discussed, and student attitudes are…

This study compared the use of three instructional organizers--the advance organizer (AO), the participatory pictorial graphic organizer (PGO), and the final form pictorial graphic organizer (FGO)--in the design and use of computer-based interactive video (CBIV) programs. That is, it attempted to determine whether a less generative or more…

Computer-based interactive video (CBIV), a hypermedia system that uses the power of the computer to support student interaction with various audio and visual media, can pose such problems for students as the potential for learner disorientation and cognitive overload. Intended to explore the applicability of Wittrock's generative learning…

This investigation of the use of white space in print-based, computer-generated text focused on the point at which the white space interferes with reading speed and comprehension. It was hypothesized that reading speed and comprehension would be significantly greater when text was wrapped tightly around the graphic than when it had one-half inch…

Describes a study of 80 undergraduate foreign language learners that compared the use of a hyper-reference source incorporating an electronic dictionary and a conventional paper dictionary. Measures of consultation frequency, study time, efficiency, and comprehension are examined; bilingual and monolingual dictionary use is compared; and further…

Compares the performance of education undergraduates with high or low spatial-skill scores who learned how to calculate surface area using hypertext, computer-assisted instruction, conventional paper materials, or program control. Results are reported for misconceptions, correct problems, time on lesson, enjoyment rating, screens viewed, and…

Explains the combination of hypertext and knowledge maps into hypermaps, and describes a study of undergraduates learning statistical material that compared the effectiveness of using hypertext versus hypermaps. Recall, reference time and accuracy, and student satisfaction are investigated, and needs for further studies are suggested. (10…

Differences in traditional student performance measures were examined following a computer assisted instruction (CAI) or a hypertext approach for mastering concepts related to intellectual property (i.e., copyright and patent) law. Seventy-six undergraduate business majors at a midwestern state university received CAI or hypertext instruction.…

Computer-based and audio tape materials were compared for their effectiveness in helping students practice Chinese language lessons. Subjects were enrolled in an intensive elementary course in Mandarin Chinese. The textbook and audio tape were prepared by the Beijing Language Institute in China, and the computer-based material was developed by the…

Describes a study that compared animated demonstrations, procedural textual instructions, and demonstrations combined with spoken procedural text to assess the effectiveness of animated demonstrations for users learning HyperCard. Results of accuracy, time on task, user responses, retention, and transfer are discussed; and future research is…
