Second language Acquisition or second language learning is the process by which people learn a second language. Second language acquisition is also the name of the scientific discipline devoted to studying that process. Second language refers to any language learned in addition to a person’s first language; although the concept is named second language acquisition, it can also incorporated the learning of third ,forth or subsequent language.
Second language acquisition is totally conscious process because it has some rules and regulations, theoretical concept or some structural pattern or systems. The language that we learn consciously after the first language is second language acquisition.
One of the most controversial issues in second language learning/acquisition theories is how learners learn second language. There has been a lot of discussion and the debate regarding this issues but the final solution is yet to be discovered. Discussion of second language acquisition process became a very controversial issue in 60s and 70s mainly after the emergence of the mentalist approach to learning theory led by Noam Chomsky, who propose the view that language learning is habit formation only language can only learned by reward and punishment. Behaviorist theory believe that language learned as the formation of behavior.
In this article,I should like to discussion about the Discourse theory in second language acquisition with particular references to the strengths and weaknesses of the many studies carried out at that time.
The Discourse Theory
There has been no shortage of theorizing about second language acquisition. The research literature abounds in approaches, theories ,models, laws, and principles.
Discourse theory refers to the process in which language can learned by communicating with the target language speaker. It follows from a theory of language use, in which communication is
