[Air-l] Empirical Studies of Effects of IM on School Writing

Does anyone know of actual, empirical studies being done on the effects (purported or real) of instant messaging on the written school work of teens and college-aged students? In parts of the world where texting on mobile phones is pervasion, the same question goes for the effects of texting. There's a lot of talk in the media on these issues, but it would be useful to know if anyone has gotten beyond the anecdote stage. Thanks, Naomi Naomi S.
