The current study investigated advanced L2 learners’ linguistic development before, during, and after a nine-month stay abroad, the extent to which contextual changes (home-abroad-home) influenced the nature and magnitude of development, and the ways in which relationships among different linguistic elements changed over time. Participants were 56 university learners majoring in French (n = 29) and Spanish (n = 27), who spent an academic year abroad in the middle of a four-year BA degree program. Oral data were collected six times over 21 months to trace development and change in complexity, accuracy, fluency, and lexis (CAFL). Results showed ongoing improvements over time on most measures, including accuracy. Correlations indicated long-term relationships between fluency and vocabulary only and that accuracy-complexity relationships emerged in instructed home contexts only. These findings suggest that the affordances of home and abroad contexts can shape learners’ linguistic development and use differently. The role of pre-departure linguistic ability is discussed as critical to understanding the nature and extent of L2 linguistic development in study abroad.

高级学习者出国前、中、后语言发展的纵向研究

目前的研究调查了高级二语学习者在国外停留 9 个月之前、期间和之后的语言发展，情境变化（国内-国外-国内）影响发展的性质和幅度的程度，以及关系的方式随着时间的推移，不同的语言元素之间发生了变化。参与者是 56 名主修法语（n = 29）和西班牙语（n = 27）的大学学习者，他们在四年制学士学位课程的中间在国外度过了一个学年。在 21 个月内收集了六次口头数据，以追踪复杂性、准确性、流畅性和词汇 (CAFL) 的发展和变化。结果表明，随着时间的推移，大多数措施都在不断改进，包括准确性。相关性表明流利度和词汇之间存在长期关系，准确度-复杂度关系仅在有指导的家庭环境中出现。这些发现表明，国内外语境的可供性可以影响学习者的语言发展和不同的使用。出发前语言能力的作用被讨论为理解出国留学中二语语言发展的性质和程度的关键。
