A set of principles that tries to explain the phenomena of the language learning process.
Knowing the theories will help SL teachers apply the best
learning methods, teach the most appropriate content, etc.
It should result in "learner centered" rather than "teacher centered" instruction
Methods differ because they emphasize
different elements of the SLA process
To date, there is no "single" method that SLA researchers
would reach a consensus about.
Acculturation
Schumann
Considers social and psychological integration of learner with
the target language group. Pays attention to social and
affective variables
The shorter the social distance, the better the SLA results.
Alberto is an example. He had a large social
distance and it affected his acquisition negatively.
Comprehensible input
Krashen
Appropriate level (comprehensible, i+1), extensive
input is needed and SLA will naturally occur.
Interaction hypothesis
Long
Acquisition happens when students interact in L2. Use
negotiation of meaning to get modified input, which ensures that
the input is at the appropriate level.
Also believes that significant amounts of input are needed.
Pushed output hypothesis
Swain
Being forced to push the language out is the trigger
that helps the learner pay attention to the language
and helps develop rules, or at least notice them.
Noticing hypothesis
Schmidt
Successful acqisition takes place when
learners notice language that they produce and also what they take in.
Negative example was Wes in Hawaii. He will never acquire proper grammar rules
because he only produced without noticing.
