In recent years, a number of models concerning problem solving systems have been put forward. However, many of them stress on technology and neglect the research of problem solving itself, especially the learning mechanism related to problem solving. In this paper, we analyze the learning mechanism of problem solving, and propose that when…

Tag clouds generated in social tagging systems can capture the collective knowledge of communities. Using as a basis spreading activation theories, information foraging theory, and the co-evolution model of cognitive and social systems, we present here a model for an "extended information scent," which proposes that both collective and individual…

Interactive simulations are entering mainstream science education. Their effects on cognition and learning are often framed by the legacy of information processing, which emphasized amodal problem solving and conceptual organization. In contrast, this paper reviews simulations from the vantage of research on perception and spatial learning,…

The purpose of this article is to review and critique each of the research studies published in this special issue. We will critique each article, derive one or more instructional design heuristics based on the findings for each study, and provide recommendations for extending particular lines of research. Three suggestions are provided concerning…

This article discusses problems in the psychological processing theory for learning disabilities assessment and describes the development and potential use of an interactive diagnostic system for testing students' processing skills for learning disabilities. (AEF)

This book examines the practical application of visual tools such as brainstorming webs, task-specific organizers, and thinking-process maps. Graphic overviews map the big picture for each chapter and synthesize the key information about each type of tool. Stories, quotes, and insights from parents, students, teachers, administrators, brain…
