Conclusion

The current essay (1) from by the deficiency of Greek EFL teachers to implement the Communicative Language Teaching curriculum in the public schools and their refusal to create opportunities for in-class interaction. In an (2) to suggest that strict grammar-focused instruction is not the only effective way of addressing second language (3), it initially explores the Interaction Hypothesis Theory. According to (4) (1983) who first introduced this theory, through in-class interaction second
language learners have the chance to negotiate meaning and improve their comprehension of new information. During that process interlocutors are able to take the necessary time to modify the new input and adjust it to their cognitive level (Mackey 1995, cited in Gass 1997).

(5) (1987) with his Socio-Cultural Theory addressed interaction from a more psychological perspective, by maintaining that second language learning is a mediation process where language serves as the mediation tool of the human consciousness. According to that there is a zone of proximal development, where the learners can achieve a micro-genetic development through collaborative scaffolding (Lantolf and Appel 1994). Even though it could not be asserted that interaction is the best method to achieve cognitive development, based on the aforementioned studies it is thought that interaction facilitates the learner in thecomprehension of new input. I hope that the present essay will be of interest to the Greek EFL teachers and will provide them with the basic knowledge concerning interaction and SLA. It could also be the trigger for further investigation of implementing in-class oral-communication and interaction in the Greek private EFL schools, where teachers and learners are usually less reluctant in applying new methodologies.
