Responds to a previous article that suggests the second-language-acquisition acquisition field has failed to realize academic respectability. Offers an overview of some of the more positive advances in the discipline. Concludes by calling for a whole systems approach to the study of second language acquisition. (Author/JL)

This study presents a formal device which can be used to display interlanguage variability while revealing its overall systematicity. Two types of variability are recognized: (1) production of a number of variant structures for a single target language structure at one point in time; and (2) variation over time that is attributable to the…

Discusses the similarities between the science of chaos/complexity and second language acquisition (SLA). Notes that chaos/complexity scientists focus on how disorder yields to order and on how complexity arises in nature. Points out that the study of dynamic, complex nonlinear systems is meaningful in SLA as well. (78 references) (Author/CK)

The need for an index of development by which second language proficiency could be expediently and reliably guaged has been acknowledged by both second language (L2) teachers and researchers. In two previous L2 studies, the search for an index of development centered on an examination of learner written performance. In an attempt to construct an…
