| Outline of Research at the Start |
The plan is to conduct studies across 5 different proficiencies towards the purpose of the larger-scale proposed project: current data suggests that relationships between the three different IELTS speaking task prompts and productive vocabulary knowledge change according to proficiency levels.
|
| Outline of Annual Research Achievements |
In the current study, we explore potential relationships between lexical diversity (with different text lengths and analysis units), utterance fluency, and general speaking proficiency. We aim to report on an investigation of approximately 105 participants from a UK university divided into three different IELTS proficiency levels. We explore a corpus of participant undergraduate presentations. We investigate and compare flemma, lemma, and simple count influences on LD measure speaking predictability, using three basic LD measures and three sophisticated measures. Following earlier research (Treffers-Daller 2013), we also examine different text lengths.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
To complete the research project, we are currently employing research assistants to process our data bank.
|
| Strategy for Future Research Activity |
By investigating whether results mirror recent findings (Myint Maw et al., 2022) that both flemmatization and lemmatization influence LD scores, we examine potential relationships between LD and our other factors, and the extent to which LD is a predictor of general speaking proficiency when simple, flemma, and lemma counts are applied . We also report on different spoken text length influences. We discuss analysis units and text length influences on LD measure predictions of utterance fluency at different levels of general speaking proficiency.
