Examines constructivism as an epistemological basis for the design and use of hypermedia systems in order to synergize the constructivist view of learning and the potentialities of hypermedia. Proposes a new conceptual framework for constructive hypermedia learning systems based on cognitive, semiotic, and social perspectives. (Contains 151…

Static, animated, and interactive visualizations are frequently used in electronic learning environments. In this article, we provide a brief review of research on visuospatial cognition relevant to designing e-learning tools that use these displays. In the first section, we discuss the possible cognitive benefits of visualizations consider used…

Describes how 2 10-year olds developed drawings and numeral systems to symbolize their mental operations while dividing unit bars into thirds and fourths using TIMA: Bars, a computer microworld, as a medium for enacting mathematical actions. The symbolic nature of their partitioning operations was crucial in establishing more conventional…

Describes the development of a simulation-based intelligent tutoring system for nurses working in a surgical intensive care unit. Highlights include situative learning theories and models of instruction, modeling expertise, complex decision making, linking theories of learning to the design of computer-based learning environments, cognitive task…

Describes a study that investigated whether second grade students internalized content and concepts embedded in a science computer simulation as opposed to treating it as a game to be played. Discusses cognitive outcomes and processes, thinking skills, use of scientific language, transfer to other contexts, and partner and gender considerations.…

Describes the design of a hypermedia tool for helping preservice teachers learn about the growth and development of children's mathematical reasoning based on research in cognitive science, and discusses results of an experiment that used single-subject methodology to compare preservice teachers' learning with the hypermedia tool versus learning…

A "science of e-learning" involves the scientific investigation of how people learn in electronic learning environments. Three elements of a science of e-learning are: a) "evidence"--a base of replicated findings from rigorous and appropriate research studies; b) "theory"--a research-based theory of how people learn in electronic learning…

The work we report in this special issue attempted to exploit the power of technology and cognitive theory to help make conceptual systems taught in large college courses truly useful in students' future lives. Facing evidence that traditional instructional models have not succeeded in this regard, we sought feasible course designs and…

In this review of the research on how current computer learning environments can foster the acquisition of complex cognitive skills, two issues emerge: (1) what cognitive accomplishments are likely in the computer environment; and (2) what factors predispose students to benefit from the environment.
