The potential of publicly shared longitudinal learner corpora in SLA research
Nicole Tracy–Ventura, Amanda Huensch · Language learning and language teaching · 2018
Most second language acquisition (SLA) researchers would agree that longitudinal data can potentially yield the most valuable insights into second-language development, yet few longitudinal studies exist. It is also rare to find longitudinal studies with data collected beyond the one year mark. In this chapter we argue for the need to adopt more longitudinal research agendas in SLA and the potential of publicly shared learner corpora to help broaden the impact of the data collected. We use as an example work from the longitudinal project, LANGSNAP, which now includes a new set of data collected in 2016, thus expanding the project to 5 years and adding a new research question, that of the long-term evolution of foreign-language proficiency.
