On the 3rd touch and go landing after touch down on Runway 28 I could see a Aircraft Y approach our runway from left to right at Taxiway C. I commented to the student to keep an eye on him to make sure he stops. Aircraft Y proceeded to cross the runway in front of us without stopping. I immediately took control of the airplane and began a full brake application. We were getting close enough to Aircraft Y that I was considering turning the aircraft off the runway to avoid contact. We were able to avoid hitting the airplane and remain on the runway. We were slightly past Taxiway D when we came to a full stop; I do not recall hearing any radio transmission from the Aircraft Y announcing his intentions. I commented to Aircraft Y 'Thanks for crossing in front of a landing aircraft and you can buy us a new set of tires.' He commented that 'he did not see us.' This is just the latest of several incursions I have witnessed on this runway. Most are caused by pilots unfamiliar with our airport; this is the first from an what I would assume to be a highly experienced pilot and was told by the lineman that aircraft is here fairly often. I feel there is a need for more emphasis and training in making pilots aware of ground procedures and traffic pattern etiquette especially at uncontrolled airports with multiple runways. Having to cross a runway to get to the designated calm wind runway which also is the longest runway (10;000 ft.) presents a huge potential for an accident.
