One of the issues I have with academic research in education is that a great deal of time is spent arguing over definitions, drawing distinctions and creating terminology, and almost none explaining phenomena or identifying causes (it’s almost as though educational researchers today reject causation as equivalent to behaviourism). Case in point: this summary of research on mobile learning offered by Graham Attwell.
