2. Language learning in tandem 
Nowadays one of the popular methods in learning FL is the 
Tandem, which involves pairs of native speakers whose aim is to 
learn each other’s language by means of bilingual conversation 
sessions, either face-to-face or remote (via Skype, Msn). Thus, the 
goal of tandem is to acquire FL with the help of real or virtual 
interaction with a native speaker. Within this learning context, each 
partner becomes both a learner of a foreign language and a teacher 
(tutor) of his/her mother tongue (or a language in which he/she feels 
proficient).
In fact the initial impression that a person may get from this 
description makes it difficult to distinguish Tandem interaction from 
other forms of interaction or from other individual study contexts. 
For example, Tandem may seem quite similar to (a) ordinary 
conversation with a foreign friend, to (b) self-tutored study, or to c) 
private lessons.
Despite the apparent resemblance, Tandem is different from 
ordinary chatting with a foreigner, who is willing to correct 
grammar and vocabulary mistakes of his/her interlocutor. One of the 
commonest techniques during Tandem lessons is assisted 
conversation. It is called assisted because the proficient speaker 
carries out a kind of a scaffolding role in order to supply the less 
proficient learner with the linguistic elements he/she needs for 
achieving his/her communication goals.

Tandem implies a phase of focus on form, which can take place 
either during or in the final part of Tandem meetings. These are 
moments when participants can explicitly discuss linguistic rules, 
lexicon and errors. Within the limits of his/her competence, the 
more proficient speaker has the responsibility of collaborating with 
the less proficient one. On the basis of these discussions, each 
learner will be able to elaborate his/her homework for the next 
session.
