While this research shows convincing examples of using
Web 2.0 services for learning, in-depth analyses of the relationship

epistemologies of what may or may not be taught in schools".
Being able to evaluate the implications of an technology, i. e.,
critical media literacy"[17], requires understanding the very
basics of this technology.
