A student and I were landing on our second flight of the day together; one other person had flown the aircraft between our flights. It was our third and final landing of the flight. Before the incident both flights had been great with no abnormalities.On the last landing; which was a normal landing; the aircraft was drifting to the right after touchdown. I relieved the student of controls and noticed that the steering was not responding normally. I applied full left steering; confirmed that there was no throttle; and tried to correct the airplane to the left. It was slow; sluggish; and barely responsive although I managed to have the airplane turn off Runway XX and onto Runway XY. Once we cleared Runway XX I applied brakes; I felt (or heard) a snap and the nose wheel collapsed. We skidded for 100 feet or so to a stop. I then notified ATC and asked for assistance. A report was filed with the airport Sheriff's office and the airport fire department and the FSDO were contacted.No one was hurt.  The airplane was taken to a hanger for inspection at a later date by order of the FSDO.
When the student pilot appeared unable to control their LSA on the landing roll the instructor took the controls after which the nose wheel snapped off and the aircraft slid to a stop.  No one was injured.
