Abstract
The paper looks at the oral exchanges between two teachers and their B2-C1 level students (Common European Framework of Reference) in a particular EFL classroom, from the perspective of the Cambridge examinations assessment standard for the category of “lexical resource”. Since teachers are the role models in terms of language production in the classroom, this research focused on revealing lexical features which characterise the classroom discourse of two teachers of English and the impact this exposure has on their students’ lexical production. This research is part of my doctoral research, which is a multifaceted analysis of authentic oral classroom exchanges in order to determine patterns and practices at the level of developing speaking skills in the EFL context.
