Given this background, I'd say there's, say, a 40% chance he likes you! Take a deep breath and enjoy this possibility. And if you so choose, take it step by step. Hartzofspace may be right. He may have been bashful, toward you!
Or, the outside possibility Willard mentioned, that he was working up nerve to talk to a teacher about a grade. Or, anything in the middle. Or, anything else entirely. All you know for certain is that he was stressed, about something. But given the background that he has complimented you a couple of times, and that the two of you occasionally make eye contact, well, you just never know.
'What was that you were whistling? It sounded like something from a movie.' (or 'Tennessee Waltz' as Willard suggests, although not sure how well that really transfers to Turkish culture, and even as an American, I'm not really sure what the Tennessee Waltz is! though have heard the phrase)
Or, bring up something entirely different, like the most recent funny story you've seen or heard.
Or, something else artful, and be brief so you can listen to and pay attention to his reaction. (I always have to remind myself to be brief because I can easily slide into the mode of all-sending, no-receiving)
