LLED 489A explores basic theories of linguistics and their application to classroom practice. As an introduction to the linguistic foundations of first and second language teaching, the course will assist teachers in making linguistically informed decisions about teaching. The course is not a comprehensive survey of Linguistics, but restricts its topics to those generally agreed to have relevance to language teaching and learning. Serves as one of several alternative prerequisites to LLED 478A. Students are directed also to LLED 489B (3 credits), which deals with topics in second language learning in relation to society and education in more detail.
