LOngitudinal Corpus of Spoken English 

reserach project

Project Overview

The newly developed learner corpus of English is designed to directly grasp L2 developmental patterns in a literal sense, not only as a whole group, but also on an individual basis. Our project team collected the same learners’ task from 2016 to 2018, creating eight data collection points in total. The total number of learners ranged from 108 to 122 during this data collection session, but the spoken production of the same 104 learners will be used for our studies. Learners are senior-high school students, who had been studying English in an English-as-a-Foreign Language (EFL) context for three years at the time of the first data collection. They speak Japanese as their first language, and they have no long-term experience in English speaking countries. For the details of the project, see Abe & Kondo (2019).
