Presents a framework for the study of hypertext. First, a historical perspective on the evolution of hypertext is provided. Next, hypertext system components are presented, and relevant psychological and pedagogical issues are analyzed. Finally, a framework for the study of hypertext, with implications for theory, research, and development, is…

This paper introduces and analyzes problems and issues in the design and use of cognitive tools in open, user-centered learning environments. It introduces a classification scheme for tool functions, and showcases several tools in a current educational hypermedia research and development effort. Information-seeking, information-presentation,…

Discusses conceptual difficulties in the field of geometrical optics and describes RAY, a microcomputer-based graphic interface that was designed to serve as a teaching aid and as a learning environment. The ability to combine theory and formal representations with real demonstrations and experiments is discussed. (Contains seven references.) (LRW)

This paper presents a model for designing computer-based simulation environments within a constructivist framework for the K-12 school setting. The following primary criteria for the development of simulations are proposed: (1) the problem needs to be authentic; (2) the cognitive demand in learning should be authentic; (3) scaffolding supports a…

Examines the learning benefits of a learner-as-designer environment simulating a real-world multimedia production house and its impact on at-risk high school students. Students showed a significant growth in their value of intrinsic goals and achieved several critical design skills. The experience provided many students, who could not otherwise…

Describes a software shell, STAR.Legacy, designed to guide attempts to help students learn from case, problem, and project-based learning. STAR.Legacy supports the integration of four types of learning environments: learner-centered, knowledge-centered, assessment-centered, and community-centered. Describes how a STAR.Legacy constructed for an…

A difficult task in creating rich, exploratory interactive learning environments is building an environment that is truly engaging. Engagement can be defined as the nexus of intrinsic knowledge and/or interest and external stimuli that promote the initial interest in, and continued use of a computer-based learning environment. Complete and total…
