The Certificate in TESOL and Second Language Acquisition provides undergraduate students with a rigorous introduction to research on the ways in which speakers of one language acquire another. It also acquaints students with the ways in which second language teaching can facilitate this process. Course work for the Certificate allows students to explore scientific models of linguistic structure and relate them to their own experiences as language learners. It further provides guidance with practical issues that arise in teaching English to adult speakers of other languages. For this reason, the Certificate is particularly appropriate for students who are considering work abroad as teachers of English to adult learners.
