Oltre l’input potenziato: il potenziamento del feedback

What is the relationship between input and feedback, in SLA? Is feedback part of the input, or is it something else? The essay explores different theoretical frameworks on this matter, then motivates its choice to include feedback as part of input, or rather, of enhanced input (Sharwood Smith 2003). Finally, it describes modulations of the feedback move in oral interaction that can "enhance" feedback to work at its best, taking into accont the effects of some crucial variables, such as age, context, frame of activity, competence level, type of error.
