SIOP Model in the classroom

In class we have been putting a lot of focus on the SIOP model. After watching the various lessons taught using this model I tried to think about whether or not this model is used in classroom that I have been in. Although I have never been in a classroom that had all ESL learners in it I have been in classrooms that had a few children learning English. In these classrooms I realized there is very little modification in the actual classroom that is designed to help these students succeed. Although they often get pulled out for extra help the assignments they must undergo throughout regular class must be very difficult for them to follow. We learned about having students use as many language skills as possible while doing assignments. For instance students should speak, write, and have visuals in order to help them fully understand the concept. Often times in regular classrooms things are not repeated enough times and are said very quickly this would be very difficult on English language learners. In my future classroom I want to implement aspects of the SIOP model so that if I have any students with a language barrier they will still be able to succeed. I am very interested in going into a ESL classroom and observing. I would love to see if the aspects that we discuss in this class are being implemented well into the classroom. It would also be great to see which methods work well rather than just discussing the pros and cons of them in class.
