What I expect to learn in 486

I have always been a PC user. I have rarely used a MAC so I am a little intimidated by the differences between the two. I expect to learn how to use a MAC properly  and learn my way around using one. I hope to learn how to become more experienced with technology. Honestly, I only use social networking sites and check email. I don't even know how to use I-tunes. I would like to become more knowledgeable and caught up with technology and get up to date on things. I hope to learn ways that will further children's education and understanding in a classroom environment. I want to know the techniques that will help me become the best teacher that I can possibly be.
