摘要:The cyberspace, the third dimension of human world, is marked by instantaneous diffusion and absence of real sense of space. A mobile élite is now living an experience of extra-territoriality. On the other side, research on knowledge co-construction implies a sociocultural vision of mind as distributed, situated, and adaptive. Post-modernism is chacterized both by destructuration and meaning construction. So, how can we design real/virtual learning environments?
