This study explores the lexical profile of essays written by 48 advanced learners of second language (L2) Russian who participated in the Russian Overseas Flagship, an intensive year-long study abroad program designed to help students reach Interagency Language Roundtable (ILR) Level 3 proficiency in all skills. Using the lexical frequency profile…

This article explores language learning as the speakers' microlongitudinal project in interaction. Using conversation analysis (CA) as a method, we present a single-case analysis on how a change occurs in the linguistic repertoire of 2 learners of Finnish. We discuss the challenges that the temporal aspect in learning poses within CA, such as the…

Linguistic complexity serves as an important measure of second language (L2) writing development. Complexity indices, however, rarely feature in the studies of learner languages other than English. Additionally, L2 writing studies have been criticized for the lack of consistency in defining proficiency. The current study addresses these gaps by…

Current quantitative methods in second language (L2) acquisition have proven useful in examining how phraseological unit production changes over time. However, these methods are limited in that they do not allow for the analysis of individual differences in those changes. This study demonstrates the potential for Latent Curve Modeling, a type of…

Within the framework of Conversation Analysis for Second Language Acquisition (CA-SLA), this study uses learning behavior tracking (LBT) (Markee, 2008) with longitudinal data to investigate word learning by one adult second language (L2) user of English. The adult is a first language (L1) user of Japanese with limited proficiency in English. Data…

This study investigates relations between second language (L2) lexical input and output in terms of word information properties (i.e., lexical salience; Ellis, 2006a). The data for this study come from a longitudinal corpus of naturalistic spoken data between L2 learners and first language (L1) interlocutors collected over a year's time. The…

This study examined variability in Chinese as a Foreign Language (CFL) learners' development of the Chinese numeral classifier system from a dynamic systems approach. Our data consisted of a longitudinal corpus of 657 essays written by CFL learners at lower and higher intermediate levels and a corpus of 100 essays written by native speakers (NSs)…

The article discusses the potential of combining learner corpus research with experimental studies in order to fine-tune the understanding of learner language development. It illustrates the complementarity of the two methodological approaches with data from an ongoing study of the acquisition of the English tense and aspect system by French…
