| Outline of Research at the Start |
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.

| Outline of Annual Research Achievements |
As per our original plan, thus far we have successfully confirmed the selection of derivations, coded them for the affixes they contain, developed vocabulary test items testing knowledge of these derivations and the various affixes they contain, and piloted the items.
However, we are still in the process of collecting data by administering tests to students. To date we have tested 70 of the planned 130 students on the full 1000 items, and plan to test another 60 by the end of the academic year. In addition, 70 other students have completed at least one of four subsets of items (170 items each). At least another 70 more students should complete these subsets by the end of October. We will equate this data with the sample of 130 students who took all 1000 items using item response theory.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
Due to the pandemic, classes were online and we were unable to collect data from students. However, classes are now all back in person, and we anticipate that we will be able to complete our primary data collection by the end of the academic year and complete our analysis.

| Strategy for Future Research Activity |
Once the analysis is complete, we plan to submit our findings to a major journal in the field of second language acquisition. Additionally, now that we have coded 1000 words for these affixes, the resulting coding data can be used with other word difficulty lists for future studies. Our own study concerns derivational/affix difficulty for Japanese learners, but the same per-derivation codings can be used to analyze derivational difficulty for learners with other L1s. Recently we conducted and published a study using word difficulty data for Spanish, Chinese and German learners using these codings. We are also in talks with a colleague about collaborating on a similar study for Arabic learners of English.
