Developing a Multimodal Learner Corpus #716

This pilot study looks at the extent learners’ L2 vocabulary affects lexical diversity across academic writing, academic presentation (written for speaking), and academic discussions. This was done by examining the relationship between students’ (n=46) L2 vocabulary size, as measured by Webb, Sasao, and Ballance’s (2017) updated vocabulary levels test (uVLT), and the lexical diversity of their texts over the three modes of production as measured by McCarthy’s (2005) measure of textual lexical diversity (MTLD).
