Comparing the ‘phrasicon’ of teenagers in immersive and non-immersive settings: does input quantity impact range and accuracy?

Foreign language learners’ phraseological proficiency remains problematic, even at advanced levels (e.g. Meunier, 2012; Meunier & Granger, 2008; Siepmann, 2008). While the Content and Language Integrated Learning (CLIL) method is believed to facilitate foreign language learning by fostering input, interaction, and output, little attention has been paid to the phraseological competence of CLIL learners. The present study aims to fill this gap as it is framed within an interdisciplinary project on CLIL in Belgium and specifically focuses on the phrasicon, i.e. the phraseological lexicon, of 5th year French-speaking secondary school learners of English in immersive (CLIL) and non-immersive (NON-CLIL) settings. The paper reports on 1) an analysis of the variety/range of the phrasicon and 2) an overview of phraseological accuracy. The analyses are based on a corpus of written productions of 180 learners. The findings of this study indicate higher frequency, range and accuracy in the phrasicon of CLIL learners.
