Narrative:

I was conducting takeoffs/lndgs with student and pattern was extremely busy. I was told to follow aircraft on base in front of us and was cleared to land. Observing aircraft ahead on final, I felt there would be no separation problems. Upon landing I saw the aircraft that was ahead of us was just turning off of runway at the opposite end. Tower told us to contact ground. Ground had us come to the tower. Upon going to the tower supervisor informed me that local controller had issued us 3 go around instructions, which we never heard. In summary: 1) separation was lost when I landed on runway while other aircraft was still on runway. 2) I did not adhere to ATC instructions (go around). I have no explanation as to exactly why this occurred. It is possible (but not probable) that I was too busy with instructing that I did not notice the problem. A more likely (but not definite) explanation could be neither of us saw the aircraft (which we did not) until we were on the ground because of our steep approach angle, and we didn't hear the go around due to a possible intermittent radio problem (which I'm not certain).

Title: INSTRUCTOR PLT OF SMA AND STUDENT LANDED WHILE PRECEDING ACFT STILL ON RWY. TWR HAD GIVEN 3 INSTRUCTIONS TO GO AROUND.

Narrative: I WAS CONDUCTING TKOFS/LNDGS WITH STUDENT AND PATTERN WAS EXTREMELY BUSY. I WAS TOLD TO FOLLOW ACFT ON BASE IN FRONT OF US AND WAS CLRED TO LAND. OBSERVING ACFT AHEAD ON FINAL, I FELT THERE WOULD BE NO SEPARATION PROBLEMS. UPON LNDG I SAW THE ACFT THAT WAS AHEAD OF US WAS JUST TURNING OFF OF RWY AT THE OPPOSITE END. TWR TOLD US TO CONTACT GND. GND HAD US COME TO THE TWR. UPON GOING TO THE TWR SUPVR INFORMED ME THAT LCL CTLR HAD ISSUED US 3 GO AROUND INSTRUCTIONS, WHICH WE NEVER HEARD. IN SUMMARY: 1) SEPARATION WAS LOST WHEN I LANDED ON RWY WHILE OTHER ACFT WAS STILL ON RWY. 2) I DID NOT ADHERE TO ATC INSTRUCTIONS (GO AROUND). I HAVE NO EXPLANATION AS TO EXACTLY WHY THIS OCCURRED. IT IS POSSIBLE (BUT NOT PROBABLE) THAT I WAS TOO BUSY WITH INSTRUCTING THAT I DID NOT NOTICE THE PROBLEM. A MORE LIKELY (BUT NOT DEFINITE) EXPLANATION COULD BE NEITHER OF US SAW THE ACFT (WHICH WE DID NOT) UNTIL WE WERE ON THE GND BECAUSE OF OUR STEEP APCH ANGLE, AND WE DIDN'T HEAR THE GO AROUND DUE TO A POSSIBLE INTERMITTENT RADIO PROBLEM (WHICH I'M NOT CERTAIN).
