The process by which people learn a second
language in addition to their native language.
SLA vs. FLA (Ellis, 1994)
Second language: the target language plays an
institutional and social role in the community.
Foreign language learning takes place in settings
where the language plays no major role in the
community and it primarily learnt only in the
classroom.
Learner Variables (Yorio, 1976) Age: children, adolescents, or adult Cognition: general intelligence, language
aptitude, learning strategies, learning style Native language: transfer (positive vs. negative) Input: free learner vs. instructed learner Affective domain: socio-cultural, egocentric
factor, motivation (learning goals) Educational background
Forms the many different domains of inquiry that must be included in a theory of SLA
A theory of SLA includes an understanding, in general, of what language is, what learning is,and for classroom context, what teaching is.
Knowledge of children‟s learning of their firstlanguage provides essential insights to anunderstanding of SLA
A number of important differences betweenadult and child learning and between first andsecond language acquisition must be carefullyaccounted for.
Second language learning is a part and
adheres to general principles of human
learning and intelligence.
There is tremendous variation across learners
in cognitive style and within a learner in
strategy choice.
Personality, the way people view themselves
and reveal themselves in communication, will
affect both the quantity and quality of second
language learning.
Learning a second culture is often intricately intertwinedwith learning a second language. The linguistic contrasts between the native and targetlanguage form one source of difficulty in learning a secondlanguage. But the creative process of forming in interlanguage systeminvolves the learner in utilizing many facilitative sourcesand resources. Inevitable aspects of this process are errors, form whichlearners and teachers can gain further insight. Communicative competence, with all of its subcategories, isthe ultimate goal of learners as they deal with function,discourse, register, and nonverbal aspects of humaninteraction and linguistic negotiation.
A theory of SLA is really an interrelated
set of hypotheses and/or claims about
how people become proficient in a
second language
Lightbown (1985) made the following claims:
1. Adults and adolescents can “acquire” a second
language.
2. The learner creates a systematic interlanguage
that is often characterized by the same
systematic errors as those of the child learning
the same language as the first language, as
well as others that appear to be based on the
learner‟s own native language.
3. There are predictable sequences in
acquisition so that certain structures have
to be acquired before others can be
integrated.
4. Practice does not make perfect.
5. Knowing a language rule does not mean
one will be able to use it in
communicative interaction.
6. Isolated explicit error correction is usually
ineffective in changing language behavior.
7. For most adult learners, acquisition
stops –”fossilizes”– before the learner
has achieved native like mastery of the
target language.
8. One cannot achieve native like command of a second language in one hour a day.
9. The learner‟s task is enormous because language is enormously complex.
10. A learner‟s ability to understand language in a meaningful context exceeds his or her ability to comprehend decontextualized language and to produce language of comparable complexity and accuracy.
An Innatist Model
Cognitive Models
A Social Constructivist Model
the Acquisition-Learning hypothesis
the Monitor hypothesis
the Natural Order hypothesis
the Input hypothesis
the Affective Filter hypothesis
'adults have two distinctive ways of developing competences in second languages…acquisition, that is by using language for real communication ... Learning… "knowing about" language' (Krashen & Terrell 1983)
• The acquired system The product of a subconscious process verysimilar to the process children undergowhen they acquire their first language
It requires meaningful interaction in thetarget language - natural communication -in which speakers are concentrated not inthe form of their utterances, but in the
communicative act.
• The learned system
the product of formal instruction and it
comprises a conscious process which
results in conscious knowledge 'about' the
language
According to Krashen 'learning' is less
important than 'acquisition'.
How to apply this hypothesis in yourEnglish class?
'conscious learning ... can only be used as a Monitor or an editor' (Krashen & Terrell 1983)
The “monitor” is involved in learning, not inacquisition.
It is a „watchdogging” one‟s output, for editingand making alterations or corrections as theyare consciously perceived. Only once fluency is established should anoptimal amount of monitoring, or editing, beemployed by the learner (Krashen, 1981).
There is individual variation among languagelearners with regard to 'monitor' use.
Over-usersThose learners that use the 'monitor' all the timeIntroverts and perfectionists are over-usersLack of self-confidence is frequently related to the overuse
of the 'monitor' Under-usersThose learners who have not learned or who prefer not touse their conscious knowledge Optimal usersThose learners that use the 'monitor' appropriately
'we acquire the rules of language in a predictable order'
Some grammatical structures tend to be acquired
early while others late. This order seemed to beindependent of the learners' age, L1 background,
conditions of exposure, and although the agreement
between individual acquirers was not always 100% in
the studies, there were statistically significant
similarities that reinforced the existence of a Natural
Order of language acquisition.
'humans acquire language in only one way -by understanding messages or by receiving "comprehensible input"
The Input hypothesis is only concerned
with 'acquisition', not 'learning'.
The learner improves and progresses
along the 'natural order' when he/she
receives second language 'input' that is
one step beyond his/her current stage of linguistic competence.
If a learner is at a stage 'i', then acquisition
takes place when he/she is exposed to
'Comprehensible Input' that belongs to level
i+1
Since not all of the learners can be at the same level of linguistic competence at the same time ,Krashen suggests that natural communicative input is the key to designing
a syllabus, ensuring in this way that each learner will receive some 'i +1' input that is appropriate for his/her current stage of linguistic competence.
How to diagnose learners‟ currentstage of linguistic competence?
A number of 'affective variables' play a facilitative, but noncausal,role in second language acquisition.
These variables include: motivation, self-confidence andanxiety.
Learners with high motivation, self-confidence, a good self-image , and a low level of anxiety are better equipped forsuccess in second language acquisition.
Low motivation, low self-esteem, and debilitating anxietycan combine to 'raise' the affective filter and form a 'mentalblock' that prevents comprehensible input from being usedfor acquisition.
Positive affect is necessary, but not sufficient on itsown, for acquisition to take place.
“consciousness” is a tricky term (McLaughlin, 1990;Schmidt, 1990)
Younger (child language acquisition) is not
necessarily better (Scovel, 1999)
If we rule out a consciousness continuum in
constructing a viable theory of SLA, and we do not hold child first language acquisition up as the ideal model of language acquisition, we must look elsewhere for the foundation stones of a theory.

Emphasize the dynamic nature of the interplay between learners and their peers and their teachers and others with whom they interact.
The interpersonal context in which a learner
operates takes on great significance, and
therefore, the interaction between learners
and other is the focus of observation and
explanation.
Language acquisition is strongly facilitated by the use of the target
language in interaction (Long, 1990).
The generative use of words: the use of words in new contexts
which stimulate a deeper understanding of their meaning (Nation,
2000).
Interaction and input are two major players in the process of
acquisition.
The negotiation of meaning has been shown to contribute greatly
to the acquisition of vocabulary (Long, 1990).
The comprehensible input is the result of modified
interaction.
Learners construct the new language through socially
mediated interaction (van Lier, 1996)
It centers us on the language classroom not just as a place where learners of varying abilities and styles and backgrounds mingle , but as a place where the contexts for interaction are carefully designed.
It focuses materials and curriculum developers on creating the optimal environments and tasks for input and interaction such that the learner will be stimulated to create his or her own learner language in a socially constructed process.

The systematic modeling of SLA is
concerned with the question: What are the most important overall factors in language acquisition?
Different models of SLA have focused on different aspects of SLA and general linguistic research.
No single model of SLA has gained wide acceptance.
