The Cognitive Activities and Learning Interactions Based on Problem Situation in Virtual Environment

The revolutionary development of computer information technology has greatly enriched the virtual environment and its forms of expression.In more and more realistic and detailed 3D virtual environments,there are lots of problem situations,in which many cognitive and learning activities also exist.These activities mainly are shown as cognitive tools,cognitive strategies,cognitive exchange,and cognitive apprenticeship.And these activities can contribute to create problem-based situated learning.Through observation and case analysis,the learning process and interactions are analyzed in-depth,and then the ring chain and five levels of interaction in learning are revealed to offer some suggestion and inspirations to today's network education and learning.
