The Center for Open Educational Resources & Language Learning (COERLL) is one of 15 National Foreign Language Resource Centers funded by the US Department of Education. The overall mission of these federally-funded centers is to improve the teaching and learning of foreign languages by producing resources (materials and best practices) that can be profitably employed in a variety of settings. COERLL's work is organized around seven basic areas:
- Applied linguistic research
- Teaching materials
- Language assessment
- Teacher development
- Less commonly taught languages
- K-12 initiatives
- Outreach and dissemination.
In more precise terms, COERLL's mission is to produce and disseminate Open Educational Resources (OERs) 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.
