Questions and Relivent information about Web 3.0 in Education

In this section, I decided to narrow down my search and look more into Web 3.0. I also wanted to see how it was being used in schools or not. As I reflect on IT in schools, most schools seem to be about 5-10 years behind technology. Yet, is this something that is a necessity? Does Web 2.0 and 3.0 even belong in education since they are too personal?

Developing Questions
Why is Web 3.0 not seemingly as common knowledge as Web 2.0?
What E-Learning tools does the idea of Web 3.0 offer?
How has it developed from Web 2.0?
What limiting factors is Web 3.0 facing in regards to education?
