Narrative:

Pre-solo flight instruction in tail dragger. Student flying aircraft after landing roll out with speed slowed to taxi speed. Student then made control inputs that sent aircraft into right and then left turn. On the left turn aircraft headed for edge of taxi way and I tried to regain control of aircraft by grabbing controls and announcing I have the aircraft. Student remained on controls and did not release until we had started a hard right turn. This hard right turn lifted right wing and lowered left wing which scraped on the ground. We stopped after 180 turn on runway and I taxied aircraft back to ramp. No injuries or damage to other property. Damage to aircraft not 'substantial'.
