Abstract:

This 21st century has appeared as the main character of important and profound changes. Information, Knowledge and Learning are three closely related terms that go together hand in hand with this digital society. ICT consolidation, the impact of Internet emergence and important socioeconomics changes represent a revolution in education and we cannot yet establish their consecuences.
Social Software is bringing a new "terminology 2.0". Internet is coming to a privileged place and there are a new generation of services and a range of tools under a collaboration philosophy. Users become consumers and generators of information with the development of Web 2.0. People belong to a new structure, the Web 2.0 Society, and this feeling feeds a sharing and collaboration philosophy. Web 2.0 is more than technology, it represents a different way of doing things on the web and the network adoption of the users. Among the emerging initiatives are the generation of a more intelligent and accessible web and the possibility of communication independently of the device.
The gap reduction between teachers teaching methods and how students are learning is a pending question for educational enterprises managers. ICT should be the bridge between teachers and students, it is also a great opportunity and an unique challenge for educational environment. New teaching-learning contexts make use of network services available to learning communities. Internet can actually be used as an open platform that offers a great quantity of web services, most of them personalized.
Tools such as blogs, wikis or podcasts, users-personalized markup systems, new ways of managing teaching-learning process, social networks, virtual reality or artificial intelligence, instant messaging, virtual worlds or social networks are becoming in the near future to "tools 2.0", that is to say, "spaces" in which knowledge is build and discussion, sharing and collaborative work are encouraged. The quality concept is expected to evolve because new methods and tools are needed for the evaluation of users' satisfaction of "services 2.0".
Terms as ubiquity, semantics, virtual reality or artificial intelligence will be common in (a near?) future and their integration on education are going to generate important changes to which society must be alert. Therefore, this 21st century is coming together with important changes such as the evolution of technology, universal access to Internet, bandwidth expansion, standards that allow accessibility to all "services 2.0", network structures that allow a proper Internet access, new behaviour codes adapted to new environments and other factors that contribute to Digital Society construction.
