Language Teaching Research Quarterly

This study examined the degree of change in test takers’ speaking performances over a 3-month period. Furthermore, it investigated the impact of learner background variables on learners’ linguistic progresses. Fifty-two Korean learners of English, who were enrolled in IELTS preparation classes, took part in the study. Their proficiency was initially established using scores from an in-house placement instrument. Upon completing a preliminary questionnaire, participants sat for an officially-administered IELTS pre-test. Their language learning data were collected each week by survey. A final questionnaire was then completed after 12 weeks of study, immediately following the official IELTS post-test. For speech analysis (i.e., lexico-grammatical and pronunciation features), pre- and post-test individual long-run speaking responses were coded to examine participants’ linguistic gains over time. Findings indicated that fluency features improved most significantly over time, although the relationships between speech construct changes and learner background variables were more complex. Implications of these findings are useful for curriculum planning and for developing of language assessment and testing, as well as validity evidence for the IELTS speaking test.
