Project Description

This project investigates the development of complexity, accuracy, and fluency in the speech of English language learners. This research is classroom-based, pedagogy-driven language development research. Participants were adult learners entering an Intensive English Program (IEP) in the United States during the year 2010. The longitudinal data were collected during class meetings, as part of the speaking curriculum at every instruction level in the IEP. The data, two-minute monologues on a given topic, were collected by each student in the IEP multiple times per academic semester, and many students remained in the IEP across multiple semesters. The topics varied by semester, by level, and sometimes by class section for pedagogical reasons. The speeches were transcribed by a native speaker experienced in transcribing non-native speech and segmented into sentence-level units, AS-units, following Foster, Tonkyn, and Wigglesworth (2000).
