The problem(s) of 21st century literacy/ies

As most people reading this will already know, I’m studying towards an Ed.D. at the moment. My (tentative) thesis title is What does it mean to be ‘educated’ and ‘digitally literate’? The impact of ICT and the knowledge society upon education in the 21st century.. You can find my thesis proposal here and bookmarks related to my studies here. My current thinking is that I’m just going to focus on the concept of what ‘literacy’ means in the 21st century as it’s a huge and confused (confusing?) field.
