The Role Of The Interaction In The L2:

In this proces the basic notion of this theory is that conversation is not only a medium of practice, but also the means by which learning takes place; it shows to us that "checks" are the key to the Second Language Acquisition process. One way the ESOL (ESL, EFL) learner realizes the gaps in their knowledge is by checking with the person they are having a conversation with. The simplest of which are known asmodification checks. There are several different types of interaction modification checks that take place during a natural conversation which help the learner advance in the target language.

· Compressible input is necessary for L2 acquisition.

To do that, the native-h. L. speaker simplify their speech in various way.

· Modifications to the interaction structure or conversations that take place in the process of negotiating a communication help make input compressible to a L2 learner.

learner is attempting to negotiate conversation in the target language the gaps in their abilities are revealed to them. These abilities can include but are not limited to pronunciation, syntax, grammar and vocabulary. The Interaction Hypothesis concludes that this self-realization, brought about by authentic interaction, will encourage the second language learner to produce target language output to negotiate meaning and seek out the knowledge they lack.
