I have a crush on my classmate. Should I talk to her on social media, as my initial step?

Some time when you are having a conversation, before you end it ask her if she would like to do something with you. Invite her to a movie, lunch, or something like that. If she says yes, then you're in luck. If not, then just say something like "maybe some other time" and try again another day. You seem like you get along fine, so it is just a matter of saying something.
