| 研究開始時の研究の概要 |
The research will start with a cross-sectional study in which we take a snapshot of a participant group at a single point in their academic trajectory. This will be followed with an intervention (longitudinal) experiment evaluating the extent to which specific vocabulary impacts upon the objective and subjective scoring of participant writing tasks at two different time points in their academic trajectory. We then investigate the extent to which such relationships and their trajectories map across different vocabulary, writing, and ultimately second language learning proficiencies.

| 研究実績の概要 |
During the past year, our key research involved an investigation into whether productive vocabulary knowledge tasks and writing tasks potentially track changes in vocabulary knowledge development over a short-term (12 week) period of study. We wanted to know the extent to which productive vocabulary knowledge task scores and lexical diversity measure scores explain changes over a short study period, and to what extent the scores relate over this short period.
Our results show that all LD measures and one productive vocabulary knowledge task (G_Lex) appear to track vocabulary knowledge growth for our L1 Japanese participants. Correlations show that productive vocabulary knowledge tasks can predict writing levels, but for the pre-test only. For the lexical diversity measure scores, the significant differences between the pre-test and post-test indicate that these measures can, to some extent, show vocabulary increases (assuming greater diversity shows vocabulary usage). Regarding the relation between productive vocabulary knowledge task scores and lexical diversity scores over a short study period, we found that PVK can only predict vocabulary in use at the pre-test, and not the post-test.

3: やや遅れている
理由
Because of various problems resulting from the Covid-19 pandemic, including the difficulty in attending international conferences, progress has been somewhat delayed, and we have decided to extend the project for a further year.
|
| 今後の研究の推進方策 |
In the final year, we plan to present our work at international conferences, including Vocab@Vic in Wellington, New Zealand, and to write up our findings for publication in international journals. We are currently working on a paper submitted to Bilingualism: Language and Cognition, which documents a study investigating the extent to which embedded vocabulary knowledge measures relate to assessed levels of writing. We found that all vocabulary knowledge indicators could predict written proficiency, although the more embedded they were, the more accurate the prediction.
