Aircraft; Human Factors; Procedure
I was watching from the ground near the hangars on the north side of Runway XX.  My student had completed two successful patterns to a full stop.  On his third final approach; he appeared to be on a normal descent until approximately 100-50 feet AGL.  The aircraft then appeared to increase descent towards the runway.  He pulled the aircraft to level flight just before the aircraft touched down.  The aircraft touched and bounced back into the air.  My student lowered the nose as the aircraft started to descend.  The aircraft began to porpoise.  On the third porpoise; the aircraft departed Runway XX on the left hand side; the nose gear collapsed and the aircraft came to a stop just off the runway.I need to re-enforce with this student what to do when the aircraft bounces.  A pitch attitude above the horizon must be maintained throughout the bounce and a go-around must be initiated.
Flight instructor reported observing his student during first solo flight lose control of the aircraft during landing resulting a landing gear collapse.
