If this trainer is a trike gear and your hitting the prop on landing, your probably not landing correct. Get with one of your instructors and have them show you the proper way. It's a prime example of cutting the throttle way to soon and trying to let the plane float in and it's more or less just flopping down on the runway and not making a correct landing. That's why the prop it always hitting the ground. There is some good pointers in what the other guys said. Keep a little of the throttle on until your over the runway and try for a little faster smoother landing and not a belly flop.
