What is CAH and what are the differences between it and CLI? How can some of the concepts talked about in the Chpater (Brown ch 9) be used in the classroom, e.g., error analysis, CLI, Stages of learner language development, fossilization.

Contrastive Analysis Hypothesis and Cross linguistic Influence are different in that CAH predicts the interference that is caused between L1 on the target language. On the other hand Cross Linguistic Influence suggest that we accept interference as a learning tool to understand errors, but does not depend on predictability. The concepts of error analysis can be useful in understanding why certain errors occur, and how they can be corrected. Mistakes will be made through the process of learning a first and second language. We as educators must understand the principles of language learning in order not to over correct learners to the point they feel unable to progress. In considering the Form Focused Instruction, I believe that to some extent it is useful in the classroom in helping children understand the true form of the language at hand. I feel that at the appropiate times that feedback is merited in order for the learner to grasp grammatical concepts better. We definately do not want learners to learn incorreclty the language due to not having corrective feedback. I remember working with missionaries in California, and they would apply the corrective feedback that I would offer them. I think that they felt I was trying to help them, and for no other reason. I feel that as educators working with second language learners we must create a comfortable condition for appropiate feedback to be given. Many questions still arise as to how much feedback is appropiate in the classroom inorder not to hinder the communication rendered. I feel it will be a work in progress for every educator to figure out.
