The nature of web 3.0
It is the “executable” phrase of Word Wide Web with dynamic applications, interactive services, and “machine-to-machine” interaction. Web 3.0 is a semantic web which refers to the future. In Web 3.0, computers can interpret information like humans and intelligently generate and distribute useful content tailored to the needs of users.

The notion of the semantic web often entails an increase in personalisation, with search engines, for example, tailoring search results to individual users, based on accumulated data about their interests and preferences. We can see the beginnings of a shift in this direction in the increasingly personalised search results returned by Google, or in the personalised newsfeeds on popular social media services like Facebook, which filters news based on users’ actions and interactions.
While the emphasis is most frequently placed on the semantic element, other key elements often mentioned in conjunction with web 3.0 are artificial intelligence, or AI; 3D graphics (like those seen in virtual worlds or gaming environments, perhaps linked to virtual reality and augmented reality, which may in turn be linked to a concept of web 3.0 sometimes called the geospatial web); connectivity of all information; and ubiquity of access to content across multiple devices in varying contexts (for an overview of these five elements, see Expert System’s Data Growth and Web 3.0).
Some useful recent discussions of web 3.0 may be found in the sources listed below. For additional sources that contrast web 1.0, web 2.0 and web 3.0, see the web 1.0 page.
Learning with web 3.0
To the extent that virtual reality and augmented reality are associated with web 3.0, these certainly have considerable implications for education: the former exposing students to immersive recordings or simulations of locations and events in the wider world, and the latter encouraging place-based learning in real-world contexts outside the classroom. This is a space to watch over coming years.
