Quietly sit next to him (at lunch or something), start with a gentle hi. Then start a conversation about something (e.g. homework), and see where the conversation goes from there.
it depends on what that guy likes.
Just tell him
Say hi and be not shy
Well the guy shuld try to talk to her
Make the "move" for him
Have someone else do it for you.
he likes her
Frequently, it does mean that, yes. The opposite is also true: Girl shy around certain guy, quite possibly because she likes him.

If the girl is shy, you should make the first move : it feels more comfortable to most girls if the guy makes the first move.... or you could just wait... if she likes you she'll tell you when she's ready. :)
If He Is That Nice He Has Got To Be Worth The Risk
I think that this girl likes this guy. When a girl blushes and smiles she might be into that guy. Hope i helped.;)
