A usage-based approach to understanding L2 learners' knowledge of English affixes
Description: Frequency-based wordlists for L2 vocabulary instruction are typically based on “headwords” in lieu of separate entries for inflections and derivations of these words. This project will test how far usage-based metrics of affix difficulty predict the difficulty of derivations for Japanese learners of English. The project will involve the creation of an explanatory Multi-faceted Rasch model of the likelihood a learner will know a derivational form given (a) their total vocabulary mastery, (b) the difficulty of the headword and (c) the difficulty of the affix(es) in the derivation.
