This research aims to answer the question, "in what ways do mediated learning environments support or hinder learner autonomy?" Learner autonomy has been identified as one important factor in the success of mediated learning environments. The central aspect of learner autonomy is the control that the learner exercises over the various aspects 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…

Examines the issue of help devices for students in hypermedia environments according to the learning context and cognitive processes involved. Describes three main types of learning situations--learning-by-doing, learning-by-instruction, learning-by-exploring--and explores the main cognitive processes involved in them. Discusses specific types of…

Describes a study that investigated the effects of learner control and of advisement in a hypertext learning environment with second-grade students who had different levels of prior knowledge about the content. Topics discussed include computer-assisted instruction; learner control; and recommendations for instructional design in a hypertext…

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…

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…
