The paper analyzes three major problems encountered by our team as we endeavored to turn problem solving examples in the domain of programming into highly reusable educational activities, which could be included as first class objects in various educational digital libraries. It also suggests three specific approaches to resolving these problems,…

Explains the "Point and Query" (P&Q) Interface which trains students to develop good questioning strategies, decrease search time and increase retention and recall. Navigation and knowledge organization in the P&Q interface are explained; and two experiments demonstrating P&Q use are presented. (Contains 16 references.) (SLW)

This discussion of the use of computer-assisted instruction in universities focuses on the quality of motion video used in hypermedia educational software. An evaluation experiment shows that end-users are not deterred by lower quality motion video that costs less. (LRW)

Explains hyper-systems and discusses their role in active learning, presents results from an expert evaluation of current hyper-systems that use HyperCard, and suggests implications for designers of educational hypermedia. System criteria discussed include purpose, domain or content, structure, navigation methods, control mechanisms, and style of…

Components of a case-based teaching architecture in a computer-based learning environment are discussed. Highlights include examples of "Creanimate," a program in which students interactively create a new animal while the "storyteller" monitors their actions looking for opportunities to present stories and questions that will…

Describes a study of students in grades two through eight that was conducted to determine the potential existence of a developmental sequence of specific association types among children and the implications for the design of interactive hypermedia materials. Highlights include schema theory; word associations; and semantic mapping and concept…

Discusses audit trails (i.e., records of learner responses) in interactive multimedia and hypermedia instruction. Topics addressed include four purposes of audit trails, including formative evaluation in instructional design, basic research, usage studies, and counseling and advising; advantages and limitations of the audit trail approach; and…

Describes a study of fifth graders that was conducted to determine the relationship among cognitive style, the structuring of the knowledge domain as controlled by the hypermedia software, and the test performance of the learner in terms of cognitive skill levels. Hypothesis testing and results of analysis of covariance are discussed. (Author/LRW)

Describes the formative evaluation of a multimedia computer system that provides remedial support for university students learning concepts concerning the structure and function of the human brain and describes usability studies of the system using the Software Usability Measurement Inventory (SUMI). Analysis of SUMI items and the student…

Analyzes the relative advantages of using text versus voice to convey verbal information in multimedia courseware and reports results of a study of undergraduates that investigated the effects of presentation method on learning and student preferences. Topics include realism, dual modality, controllability, content characteristics, learner…

Reports the preliminary results of a research project that investigated the phenomenon of disorientation in hypertexts with middle school students. Presents experiences in setting up a benchmark for measuring this phenomenon and lessons learned regarding measuring the performance of people using hypertext technology in an educational environment.…

Discusses the Baltimore Learning Community Project, a collaborative effort that includes the Baltimore City Public Schools, the University of Maryland (UM), and Johns Hopkins University. Focuses on the UM component that involves the development of telecommunications software applications for middle school science and social studies teachers.…

Describes the design and exploratory use of an interactive hypertext program, SKEIM (Shell for Knowledge Engineering, Instruction, and Measurement), that was developed to record university students' review strategies of a set of lecture notes. Topics discussed include domain experts; navigation; text display guidelines; and the relationship of…

Describes a study of undergraduates at Aston University (United Kingdom) that investigated whether maps were an appropriate navigational aid for searching in a hypertext environment. Task performance, system use, previous computer experience, perceptions of the system, and cognitive map data are examined; and implications for hypertext system…

Describes the design of a hypermedia application, "Set on Freedom," on the American civil rights movement and presents preliminary qualitative and quantitative research on its use in a seventh- and eighth-grade classroom. Results suggest that hypermedia applications can be designed to support development of historical thinking. (Contains…
