| description | This paper discusses the syntactic complexity factors contributing to the achievement of a higher proficiency level
in English speech. Here I have examined complexification at the sentential, clausal, phrasal and nominal level of
syntactic organisation in a Korean learner spoken corpus using quantitative measures and compared the scores
with holistic ratings of learners’ overall speaking quality. After the normality assumption analysis confirmed that
the logistic regression was appropriate, an analysis was performed to ascertain the effects of complexity measures
on participants’ L2 proficiency. First, length-based complexity features, namely, MLT and coordinated phrases,
namely, CPT and CPC were found to be predictors for English speaking proficiency. Next, the logistic regression
model was statistically significant and explained 36.3% of the variance in classification according to L2
proficiency and correctly classified 75.4% of cases. Results also showed that when learners come to use the
coordinated phrases per clause proficiently, they were over 24 times more likely to achieve higher proficiency in
spoken English. Finally, an effective equation was proposed to help educators classify EFL learners according
to proficiency in L2 speech after gauging the selected complexity dimensions. However, more comprehensive
studies which consider other methods of unit segmentation for spoken data or include more measures to predict
L2 speech proficiency, are necessary to verify the results of this study. |
