Interpretare gli esiti della verifica e della misurazione linguistica in italiano L2. Il ruolo delle percezioni e degli usi linguistici dichiarati

The paper illustrates a study developed from two projects carried out in two different primary school contexts: the first, in which plurilingualism constitutes an individual characteristic derivable from a migratory background (Scandicci - FI); the second, in which plurilingualism represents a social fact (Autonomous Province of Bolzano).
