The Essentials of Language Teaching is a resource website for teachers in foreign language and second/additional language learning contexts. It provides a concise overview of the guiding principles and evidence-based practices currently used by experienced language teaching professionals. For the Essentials, the goal of language learning is the ability to communicate, that is, to use the language for specific purposes. For this reason, the Essentials promotes a learner-centered approach to teaching that uses meaningful tasks, practical materials, and guided discovery activities to develop communicative competence.
