No class disadvantage or advantage?

Ive been reading post by other classmates on a regular basis. I feel I am at a serious at disadvantage because I am not able to discuss or add anything to what is currently going on in the classroom. I do not understand terminology, its purpose, school expectations etc. I feel my comments are limited to just asking questions. Like what is this?, what does this do? but that is as far as it goes.
Then again, because I am not teaching, I can focus more on the personal side side of what I learned instead of having so many outside factors to consider? When i do my reflections I will only be able to discuss how this learning experience has affected me personally. I hope this will be enough.
