1. Definition of SLA
SLA is a term that refers
To the study of individuals and groups who are learning a language subsequent to learning their L1 as young children, and
to the process of learning that language
2. Aims of SLA
In trying to understand the process of SLA, we are seeking to answer three basic questions:
(1) what exactly does the L2 learner come to know ?
(2) How does the learner acquire this knowledge ?
(3) Why are some learners more successful than others?
3. Perspectives of SLA
The tudy of SLA involves a multidisciplinary approach (developed from the 1950's) and has yielded important insights.
Generally speaking, there are three main perspectives:
Linguistic
Pschological
Social
Linguists emphasize
the characteristics of the differences and similarities in the languages that are being learned , and
the linguistic competence (underlying knowledge) and linguistic performance (actual production) of learners at various stages of acquistion
Pyychologists and psycholinguists
emphasize (how)
The mental or cognitive process involved in acquisition, and
The representation of languages in the brain
Socialinguists and social psychologists
emphasize
Variability in learner linguistic performance, and more extended communicative competence (pragmatic competence) and
Group-related phenomena, such as identity and social motivation, and the interactional and larger social contexs of learning.
