Are input and output alone in SLA communications

This paper aims to check whether the mere materials of SLA are input and output or there is another practical option. To this aim, some perspectives reviewed and some studies compared in terms of the correct form and meaning production of language (output). Different functions of output and the way it is thought about, produced and revised are discussed in detail. Two compared studies revealed how produces the output correctly in terms of the form and meaning. Finally, the paper concluded that, in respect of the reviewed studies, input and output are not the mere materials to SLA and a more practical one can be dialogue, which at least provides more accurate learning.
