Exams are not productive in any ways.I remember,when i was doing a maya course years ago,they decided to make a written test and it was a fail.Why?Because you understand more about it if you do it in the program and you visually see your mistakes.(this is not math).
-Make one small level and make sure everyone copyes what you do.Introduce third and first person perspective so that they feel more motivated.You will notice that some people will do it in a different way.That is the start of creativeness being awaken!Let them do so.
-Than with the same assets tell everyone to make a small personal game level(make sure you keep restrains on them and that the level is small.Two- three rooms at most or they are lost!)
-And at the end,try to pair them in groups of x2 so that they can make a small,more complex game together.This is the most difficult part as one of the two students will try to rise and force his way on doing things on to the other more ¨¨timid¨¨ person.DONT let that happen or they will not learn nothing.Be the bridge between them.Even when you guys are having a small break,go and drink something in the coffee shop with them and make sure they chat between them about the work.
