What do I want to learn through CALL!?

When living in this world, which computer becomes necessary in our daily life, how to learn through computer becomes eqal important. What I expect to learn through this class is that I can have the ability to teach English at home by using computer and internet, which is not impossible I think. When the time comes to the end of this class, I hope I can know more about CALL, including software, website, .....etc. What is special is I hope I can know something just a little bit of learning other languges besides English, for example, learning Chinese. Anyway, it's important to LEARN something in this class.
