Outline of Annual Research Achievements

The corpus analysis has led to talks at 2 international conferences, a published paper and a PhD thesis. Our current findings are that Lexical Diversity (LD) measures predict the IELTS bands of hand-marked essays, but the LD of spoken transcripts do not predict IELTS bands. Also, when counting words, it makes a difference if you count words as lemmas, flemmas or word families.

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

We had intended to collect a little more data by this point, unfortunately due to the QMUL pre-sessional 2022 course still being online (due to Covid19) we could only collect an additional 105 sets of written and spoken data to add to the database. This means that we will need to collect one more batch of data in September 2023 to have a satisfactory sample size with which to fully test our various hypothesis'. Despite not having quite as much data to work with (as initially anticipatated) we completed some analysis and were able to present this at conferences and also publish a paper in a journal.

Strategy for Future Research Activity

We plan to collect more data from Queen Mary University of London pre-sessional students in September 2023. We also expect to present our findings at a large international conference (Vocab@Vic New Zealand December 2023) and then publish more of our findings in high-impact journals.

Causes of Carryover

Due to ongoing Covid19 restrictions on travel it was not possible to attend (in person) all conferences, as originally planned.
