While this research shows convincing examples of using Web 2.0 services for learning, in-depth analyses of the rela- tionship between Web 2.0 technology on the one hand and teaching and learning on the other hand are still rare. How- ever, the significance to understand the implications of tech- nology is underlined by Noss [28] who asks “[w]hat kinds of pedagogy are appropriate to using [a new] technology and, more fundamentally, how does this technology change the 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.
