In this proposal, there is a focus on structure based instruction and it is given emphasis to form and accuracy.
In its origin, there are grammar translation and audio-lingual approaches.
According to this proposal, free language use is not allowed because students can make mistakes and if they repeat these mistakes, they can be habits or get fossilized. Therefore, teachers should give corrective feedback to the students.
However, the supporters of more communicative approaches argue this view and they suggest that errors are natural for learning and it is better to encourage learners to develop fluency before accuracy, but allowing learners too much freedom without correction and explicit instruction is a negative side of this view.
