La competenza fraseologica in italiano lingua straniera tra i livelli elementare e intermedio. Un approccio per bigrammi

Phraseology constitutes an indisputably importantareaof language proficiency. Among the methods devised to explore this domain, semiautomated analysis of learner corpora has yielded important findings, especially in the case of intermediate and advanced levels. This paper investigates phraseological competence in Italian as a Foreign Language between the A2 and B1 levels of the CEFR. We collected 160 texts based on different combinations of task difficulty and learner level and we compared, through two-way Anova tests, the different groups. Results show that A2 leaners produce more non-collocational bigrams with respect to other groups, but when they attempt a B1 task they experience difficulty in producing high frequency bigrams. Implications for instruction, assessment and further research are discussed.
