The flight instructor reported that he and his student were practicing landings to the runway. He reported that his student's approach was unstable and left of the centerline as the airplane approached the runway numbers. The instructor called for a go-around, and applied full throttle, and the student pitched for a climb but the airplane stalled. The instructor pushed the nose down to increase the airspeed, but the airplane impacted the runway. The airplane sustained substantial damage to both wings and the empennage.

The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
