COERLL's mission is to produce and disseminate Open Educational Resources (OER) for the Internet public (e.g., online language courses, reference grammars, assessment tools, corpora, etc.). The term OER refers to any educational material offered freely for anyone to use, typically involving some permission to re-mix, improve, and redistribute. Thus, COERLL seeks to promote a culture of collaboration that lies at the heart of the Open Education movement. In addition, COERLL aims to reframe foreign language education in terms of bilingualism and/or multilingualism. As such, all COERLL resources strive to represent more accurately language development and performance along dialectal and proficiency continua.
