Hi Thomas,
Yes, that's an interesting discussion - it is true we "hijack" terms from various disciplines in academia...in fact, knowledge construction is really about exploring concepts for the sake of understanding. Much happens to support understanding and often terms pop up in various
contexts but with slightly different meanings - thus your reference to "hijacking" :)
Regarding young people and their use of digital and mobile media - my sense is that while young users of these technologies may be knowledgeable about the actual functions of the technology, they still have to be taught academic skills like research. Therefore although we as teachers may be playing catch up, or feel like it sometimes with technology use, we still are the ones who must guide the learning process and develop those academic skills not yet developed in our students.
