One common way of tapping change in L2 perfor mance has been to analyze learner speech and writing through the subdomain s of complexity\, accuracy\, fluency\, and lexis (CAFL)\, which has eventu ally become an L2 assessment framework (Norris & Ortega\, 2009). However\, SLA research has failed to document that each CAFL construct conjointly d evelops over time (Bulte & Housen\, 2020). By the same token\, expecting l inear change in longitudinal learner performance data has been challenged by the dynamic usage-based perspectives (DUB) as this strand of SLA resear ch has proved empirical evidence for non-linear developmental trends in L2 performance over time (Verspoor\, 2017). Especially given the high degree of variation in individual learning trajectories\, it has been claimed th at levelling off individual scores and using group means to generalize ind ividual gains could be methodologically risky and misleading (Lowie & Vers poor\, 2019). Therefore\, alternative methodologies using non-linear advan ced modelling techniques have been called upon to capture these highly var ied developmental patterns in longitudinal designs (Lowie & Verspoor\, 201 9\; Murakami\, 2016).\\r\\nMotivated by the above-mentioned gaps in the li terature\, this longitudinal study pertains to the dynamic relationship am ong linguistic performance constructs as CAFL across contexts over time th rough a cross-sectional quantitative and qualitative analysis of learner p erformance data. Taking a DUB approach (Behrens\, 2009\; Verspoor & Behren s\, 2011)\, this study explores any form of systematicity in CAFL construc ts as indicators of language development. Additionally\, taking one compon ent of CAFL\, syntactic complexity development in the form of subordinatio n\, this study looks for empirical evidence for systematicity of interlang uage. In reference to the systematicity of language as a DUB system\, this study also investigates the development of one type of form-use-meaning-m appings (FUMMs\, Verspoor\, 2017) in the form of infinitival and gerundial verb complement structures (VC) in a cross-sectional design. Finally\, th e current study aims to create a computerized model to predict L2 performa nce over CAFL measures pertaining to language modalities (e.g.\, written a nd spoken)\, context (study abroad vs. at home formal instruction)\, task types\, and proficiency levels. The longitudinal written data for this stu dy come from the Study Abroad Language Acquisition project (SALA\, Perez-V idal\, 2014). A subcorpus of diaries from this project was compiled by the researcher\, consisting of 110K words from 12 sojourners (tertiary level Spanish/Catalan bilinguals learning English as an L2) who provided one dia ry entry per week (a total of 175 texts) over an academic semester (12-17 weeks) abroad in an Anglophone context. The dataset was first transformed into CHAT format and then coded for CAFL measures using CLAN (MacWhinney\, 2000). The dataset was also coded and explored for infinitival and gerund ial VCs via AntConc (Anthony\, 2019). Spoken data from the Longitudinal Da tabase of Learner English (LONGDALE\, Meunier & Littré\, 2013) will be an alyzed for oral development upon its release in 2021. In the session\, pre liminary observations and textual and virtual explorations of the dataset will also be presented to discuss several DUB phenomena in the dataset.\\r \\nIf you would like to listen to this talk\, please contact Dr. Zeynep K öylü (zeynep.koylu@unibas.ch [mailto:zeynep.koylu@unibas.ch]) to obtain the necessary Zoom link. \\r\\nReferences\\r\\nAnthony\, L.

Measuring second language (L2) proficiency and development ha s long been a disputatious topic in second language acquisition (SLA) rese arch (Leclercq et al.\, 2014). One common way of tapping change in L2 perf ormance has been to analyze learner speech and writing through the subdoma ins of complexity\, accuracy\, fluency\, and lexis (CAFL)\, which has even tually become an L2 assessment framework (Norris &\; Ortega\, 2009). Ho wever\, SLA research has failed to document that each CAFL construct conjo intly develops over time (Bulte &\; Housen\, 2020). By the same token\, expecting linear change in longitudinal learner performance data has been challenged by the dynamic usage-based perspectives (DUB) as this strand o f SLA research has proved empirical evidence for non-linear developmental trends in L2 performance over time (Verspoor\, 2017). Especially given the high degree of variation in individual learning trajectories\, it has bee n claimed that levelling off individual scores and using group means to ge neralize individual gains could be methodologically risky and misleading ( Lowie &\; Verspoor\, 2019). Therefore\, alternative methodologies using non-linear advanced modelling techniques have been called upon to capture these highly varied developmental patterns in longitudinal designs (Lowie &\; Verspoor\, 2019\; Murakami\, 2016).

Motivated by the above -mentioned gaps in the literature\, this longitudinal study pertains to th e dynamic relationship among linguistic performance constructs as CAFL acr oss contexts over time through a cross-sectional quantitative and qualitat ive analysis of learner performance data. Taking a DUB approach (Behrens\, 2009\; Verspoor &\; Behrens\, 2011)\, this study explores any form of systematicity in CAFL constructs as indicators of language development. Ad ditionally\, taking one component of CAFL\, syntactic complexity developme nt in the form of subordination\, this study looks for empirical evidence for systematicity of interlanguage. In reference to the systematicity of l anguage as a DUB system\, this study also investigates the development of one type of form-use-meaning-mappings (FUMMs\, Verspoor\, 2017) in the for m of infinitival and gerundial verb complement structures (VC) in a cross- sectional design. Finally\, the current study aims to create a computerize d model to predict L2 performance over CAFL measures pertaining to languag e modalities (e.g.\, written and spoken)\, context (study abroad vs. at ho me formal instruction)\, task types\, and proficiency levels. The longitud inal written data for this study come from the Study Abroad Language Acqui sition project (SALA\, Perez-Vidal\, 2014). A subcorpus of diaries from th is project was compiled by the researcher\, consisting of 110K words from 12 sojourners (tertiary level Spanish/Catalan bilinguals learning English as an L2) who provided one diary entry per week (a total of 175 texts) ove r an academic semester (12-17 weeks) abroad in an Anglophone context. The dataset was first transformed into CHAT format and then coded for CAFL mea sures using CLAN (MacWhinney\, 2000). The dataset was also coded and explo red for infinitival and gerundial VCs via AntConc (Anthony\, 2019). Spoken data from the Longitudinal Database of Learner English (LONGDALE\, Meunie r &\; Littré\, 2013) will be analyzed for oral development upon its re lease in 2021. In the session\, preliminary observations and textual and v irtual explorations of the dataset will also be presented to discuss sever al DUB phenomena in the dataset.
