Rapport in language learning refers to the relationship between the teacher and the learners. Teachers try to build good rapport with the learners in order to produce an environment that will help learning.
Classroom management tools such as eye contact, body language and learning and using names can help to build rapport.
In the classroom
Building good rapport is often a matter of personalities, and many teachers will have excellent rapport with one class and bad rapport with another, for no clear reason. Personalisation can help build rapport, as learners and teachers find out more about each other.
