Narrative:

I was providing a biannual flight review/instrument proficiency check (ipc) (in accordance with far 61.56/61.57) with a student who was not current. I was flying right seat; and he was flying left seat. The student had very low time in a piper comanche and prior to the flight; I gave him a briefing on the operation and systems of the aircraft. We were almost complete with the flight review and we came back to the airport to do a few touch-and-gos in order to get him comfortable landing the aircraft. On the first approach to landing; we touched down on the runway and began our roll out while getting ready to add power and take back off. I could tell that he had his hands full with the aircraft and decided to give him assistance in performing the touch and go. I announced; 'full power; flaps up' and let the flaps up and added full power for him.as we started accelerating down the runway; it felt as though the gear collapsed. We were on belly skidding down the runway. I announced; 'I have the aircraft' and proceeded to use the rudder to maintain directional control; and pulled the power back to idle. We came to a stop on the runway; turned everything off; and exited the aircraft. After getting out; I went and looked back in the aircraft; and the gear lever was in the up position. I asked the left seat pilot how it got that way; and he told me that he believed that he moved it to the up position before rotation.on a side note; earlier that day my student had been flying a beechcraft baron. On a baron; the flap lever is on the left side of the control assembly; exactly where the gear lever is on a comanche. He had been doing touch-and-gos in the baron earlier so he was used to moving the lever on the left side of the control column in order to let the flaps up. We believe that he made the mistake of letting the gear up by mistaking it for the flap control lever.
