1. Interlanguage
Chapter 9

2. What is Interlanguage? Interlanguage
The system that language learners create when learning a second language
Learner Language
Studying the production of a language learner
Speaking
Writing
Sometimes, speakers make errors and mistakes. If we know why they made them, we can better fix their language.

3. Stages of Learner Language Development
Presystematic Stage
Emergent Stage
Systematic Stage
Postsystematic Stage
There are different stages to creating language systems and perfecting grammar

4. Presystematic Stage Makes random errors Not aware of errors
Example: The different city is another one in the another two. I will studied for six years. I want to become a physicotrafic.

5. Emergent Stage
Learner can now use general rules of language mostly correctly
The listener can now understand what the learner is saying
Backsliding – when the learner learns something and then reverts back to an incorrect form
Example: (page 245)

6. Systematic Stage
Learner becomes more consistent in producing a second language
Learner can understand the errors that they make and fix them
Example: I am eaten at the restaurant. No… wait… ah! I am eating at the restaurant! Sorry…

7. Postsystematic Stage Also called stabilization
Few errors when producing language; mastery stage
Fossilization – minor errors can no longer be self-fixed
Example: (page 246)

8. Group Work Consider each of the stages: Presystematic Stage
Emergent Stage
Systematic Stage
Postsystematic Stage
What kind of activities and learning strategies are appropriate for students at each level in the stages of learner languages?

9. Mistakes and Errors Mistake – random or “slip”
Errors – consistent problem in producing language
Overt and covert errors – easy or hard to detect
Global and local errors – over the whole language or only in certain contexts
Errors of addition, omission, substitution, and permutation – what kind of error? Leaving out? Adding too much?
Levels or domain of language – What part of language is the error in? Pronunciation? Grammar? Syntax?
What is the biggest error Korean students typically make when learning English?

10. Input and Frequency
Input – what kind of language does the learner receive
Frequency – how often does that language come?
How are language input and errors related?
How are frequency and errors related?
