This course explores the various theories that scholars and researchers have put forward concerning second language acquisition, or how people learn languages. Since it is language learning that is being examined, it is important to understand what language is. Linguistics explores this question, and hence, this course draws to some extent on insights from linguistics. In addition, as people and learning have both social and psychological dimensions, the course also draws on insights from sociology and psychology. In other words, SLA is an inter-disciplinary subject that draws on all three disciplines, as well as the sub-disciplines and research areas that inter-relate them. Three hours of instructor-led discussion per week.
