Discourse aspects of interlanguage

Second Language Acquisition by Rod Ellis (1997)

New Words
Comprehensible input: That part of the total input that the learner understands and which is hypothesized to be necessary for acquisition to take place.
Negative evidence/feedback: Information given directly or indirectly to learners that an interlanguage hypothesis is incorrect.
Scaffolding: The process by which learners utilize discourse to help them construct structures that lie outside their competence.
Zone of proximal development: Vygotsky uses this term to refer to the cognitive level that a child is not yet at but is capable of performing at with adult guidance.
Auto-input: This refers to the possibility that learners’ own out-put can serve as input to their language acquisition mechanisms
