Second-language acquisition research over the past fifteen years has provided considerable evidence for the hypothesis proposed by Corderin 1967 that learners of a second language do not simply learn what they are taught, but act on the input in ways determined by what Corder called a'built-in syllabus'. Most of this research has been carried out with learners who have experienced informal exposure to English as well as formal instruction.Learners who have been exposed to formal classroom instruction in the absence of rich'communicative'exposure to the second language (L2) have been observed by some to exhibit error patterns (Felix 1981) and acquisition orders (Pica 1983) which are highly similar to those of learners receiving no instruction or instruction in addition to'communicative'exposure. Others have observed that learners with no exposure outside the classroom exhibit acquisition orders (Lightbown 1983a, 1983b) and error patterns (Pica 1983) which differ to some extent from those of'natural'acquirers. Overall, the amount of research on'instruction-only'learning has been very restricted. Nevertheless, some writers have proposed the strong hypothesis that instruction does not alter the path of development (Felix 1981, Krashen 1982, Pienemann 1985), but may slow or speed the rate of development according to the extent of appropriate matching between instruction and the learner's stage of interlanguage development. Two explanations have been proposed for the hypothesized ineffectiveness of instruction. First, there is Krashen's hypothesis that classroom instruction which is focused on language form affects what he calls' learning'but not'acquisition'. That is, knowledge gained in the formal instruction periods (focus on form) in the classroom setting will be available only as a'monitor'which may, under certain conditions, alter the learner's output but not his or her underlying interlanguage system. It is this underlying system which determines the structure of language produced'spontaneously'.
