Stages of an English Language Learner (youtube Video)

I never realize that English Language learners went through stages of language development, but after watching the video it was evident to me that children progress in their language skills within a long period of time. In the school I work as a substitute one of the students is a seven grade boy that just came from Haiti. Last year was his first year of school in the United States and he knew no English at all. Every time I had this class I noticed that he did not talk for anything and now I realize that he was going through the initial stage of speech. This year I had his class again and I was very surprised when he approached me and asked me very clearly if he can go to the bathroom. I did not show him that it was a big deal that he spoke English but now I realize he was going through the stage where they tend to say small words to communicate. The first person who I thought of after watching this video was this Haitian student because it was a perfect example of the development he is going through in order to become an English speaker. I know that in another year this student will be able to speak more openly and his academic skills will begin to show progress.
