Narrative:
Student, after landing, made a large veer on the runway. I was trying to make sure of staying on the runway. Suddenly I realized he had his hand on the gear selector. I yelled out, 'no!', and grabbed the switch and placed it back in the down position just as he began to move his hand away from selector, which he had placed in the up position. The aircraft was sitting in the normal position until he veered again. Then the gear began to collapse under the weight of the aircraft. Having the gear selector in the down position while the weight of the aircraft collapsed the gear caused the push rods to bend. The aircraft came to rest sitting on the tail with nose gear still fully locked and extended.
