Outlines a contrastive analysis model and a non-contrastive analysis model for studying interlanguage in strictly bilingual settings, and suggests a bidimensional framework, including both linguistic and curricular components, for studying interlanguage in multilingual settings.

Discusses variation in interlanguage and suggests two hypotheses to explain such variation as multiple internal representations of a form and processing errors. Suggests that second language learners can initially represent new forms as prototype schemas, and that such non-discrete representations are a third source of variation in interlanguage.…

Viewing language learning as another skill acquisition process allows correction to be seen differently. An "error" occurs when knowledge is faulty, a "mistake" when only the performance is faulty. Mistakes can be corrected when (1) the student desires correction; (2) knows what is correct; (3) knows a mistake has occurred; and…

Errors in second language learning are viewed as evidence of the learner's hypotheses and strategies about the new data. Error observation and analysis are important to the formulation of theories about language learning and the preparation of teaching materials. Learning a second language proceeds by a series of approximative reorganizations…
