Narrative:

In a student-provided C172; a climb; VOR tracking (30 to 35 min); minimum cruising altitude (MCA); stall recognition and recovery training at 3;000 ft MSL went with out incident or problem. During the return to the airport with the airport within gliding distance; an engine out exercise was attempted by placing the fuel selector in the 'off' position. After getting the aircraft to best glide; two engine restarts were attempted - primer in and locked; mags - checked; carb heat - on; mixture - full rich; throttle - full; fuel selector - both. Both attempts were unsuccessful. Unable to make the airfield; elected to do off field landing. During the landing the nose wheel was damaged. After landing; I checked the student and myself for injuries and none were observed. I then turned off the master; removed the key and set the fuel selector from 'both' to 'off'. I then notified the FAA.
