Personalisation is an important part of the communicative approach, since it involves true communication, as learners communicate real information about themselves.
Example
The learners have read a text about sports. In pairs they talk about what their favourite sports are and whether they prefer to play or watch.
In the classroom
Personalisation is important for several reasons. It makes language relevant to learners, makes communication activities meaningful, and also helps memorisation. Personalisation can take place at any stage of a lesson.
