Second Language Acquisition Theory : Understanding Key Concepts and Terms

Abstract

The field of Second Language Acquisition (SLA) research has grown into a vast network of academic discourses in recent years. Coming to grips with myriad terms and concepts associated with the field can sometimes seem like a Herculaen task beyond our capabilities. This paper hopes to provide clear explanations of those terms and constructs that are essential for entering into dialaogue with the most prominent theorists and researchers in SLA today. An evaluation is also made of the theoretical and pedagogical value of diverse constructs including: Interlanguage, Fossilization, Language Acquisition Device, Curriculum Objectives, and Task Based Approaches. An example is also provided of how newly-acquired knowledge of language acquisition can be chanelled effectively into a curricular needs-analysis for a particular educational setting.
