20s + too crazy to think he may be interested? (will answer back)?

There's this guy doing the same uni course as me- we're studying to be teachers and so in a way I'm just one girl out of many. We've only been doing this course this year, and I've only really talked to him a few times this semester as it's the first time we've been in a tutorial together. I noticed him before though- we would pass each other in lectures and on numerous occassions I would talk to someone he was walking with, in passing, and he would look at me.
We did a group assignment this term together- and when he was speaking, alot of the time he tended to look to me even though there were others in the group. While I'm a quiet person, I was coming up with ideas for the assignment in previous sessions but in this meeting I hadn't said anything so it wasn't like he was replying to what I had said- but I don't know if maybe he thought I was the one guiding the assignment?
We recently went on prac for four weeks- and during the time I added him and messaged him on facebook to find out how things were going- I thought it would be a good step to take, giving another means to communicating... but he doesnt use facebook often so conversation stopped after a few messages. Now we're back at uni- I haven't had a chance to talk to him (mainly because when theres an opportunity I run out of fear.. stupidly). I've caught his eye a few times in class- but at the same time I don't know whether that means much...
Could he be interested? Or am I just dellusional? What can I do next? We've only got a few weeks left before holidays and I can't stop thinking about him...I dont know how many opportunities I will have though in the coming weeks
To me, he seems like he is one of the more introverted... I just don't know how to make a move and be more assertive.. any advice?
How can I let him know that I like him without being too obvious?

You don't mention how is is with other students. Does he pay attention to any other people (the so called "many") Try to figure out his personality- is he shy, introverted, outgoing, friendly to other) Then act accordingly. You might have to take the first move and be more assertive. Good Luck
