On second touch and go at bct, during a soft field landing for practice for student's commercial rating. On landing, the student had let nose wheel touch runway after flare. I told him to please keep the nose wheel light, and as he brought up nose he retracted gear. At this point there was no time to correct situation, speed was under 25 KTS. Nose gear retracted and propeller struck runway. Mains stayed because of overctr action. I had guarded the gear handle until mains touched down and then left it. 4 ways to which I think this could have been prevented are: guard gear handle at all times on ground until airborne. Move squat switch to main gear not nose or to pitot system like beech duchess. Install some type of lock to make retraction more difficult like done on bonanzas. For training aircraft a manual switch on instructor's side to electrically disable gear system. Never trust a student.

Title: INADVERTENT EARLY GEAR RETRACTION ON RWY DURING TOUCH AND GOES BY STUDENT (PVT) PLT.
Narrative: ON SECOND TOUCH AND GO AT BCT, DURING A SOFT FIELD LNDG FOR PRACTICE FOR STUDENT'S COMMERCIAL RATING. ON LNDG, THE STUDENT HAD LET NOSE WHEEL TOUCH RWY AFTER FLARE. I TOLD HIM TO PLEASE KEEP THE NOSE WHEEL LIGHT, AND AS HE BROUGHT UP NOSE HE RETRACTED GEAR. AT THIS POINT THERE WAS NO TIME TO CORRECT SIT, SPD WAS UNDER 25 KTS. NOSE GEAR RETRACTED AND PROP STRUCK RWY. MAINS STAYED BECAUSE OF OVERCTR ACTION. I HAD GUARDED THE GEAR HANDLE UNTIL MAINS TOUCHED DOWN AND THEN LEFT IT. 4 WAYS TO WHICH I THINK THIS COULD HAVE BEEN PREVENTED ARE: GUARD GEAR HANDLE AT ALL TIMES ON GND UNTIL AIRBORNE. MOVE SQUAT SWITCH TO MAIN GEAR NOT NOSE OR TO PITOT SYS LIKE BEECH DUCHESS. INSTALL SOME TYPE OF LOCK TO MAKE RETRACTION MORE DIFFICULT LIKE DONE ON BONANZAS. FOR TRAINING ACFT A MANUAL SWITCH ON INSTRUCTOR'S SIDE TO ELECTRICALLY DISABLE GEAR SYS. NEVER TRUST A STUDENT.
