Human Factors
Tailwheel training. Upon teaching wheel landings to a student; the stick was not moved forward to kill the lift for landing. Thus; rudder authority was lost and we skidded off the runway into a ditch. I had the controls immediately after we went for the ditch. I added full power to avoid flipping nose over in the ditch. We crossed this ditch and were heading towards another ditch on the opposite side of the taxiway. I decided to not chance a second ditch crossing and tried to keep it on the taxiway. At this point in time; the tailwheel locked and we rotated counterclockwise and the right wing skidded across the ground. The only damage was on the right wing tip next to the aileron.
First time in aircraft and type; student and instructor were practicing wheel landings in a PA-18. As the wheels touched; a few bounces occurred and the plane began to fishtail and spin. Action was taken to try to correct the spin but the plane's wings began dipping and wheels skidding. A complete 360 occurred on the runway and as well as a wing strike. Plane continued in the grass before control was regained on the taxiway. No injuries and slight wing damage but no other damage to aircraft.
A flight instructor and his student; practicing wheel landings in a PA-18 Super Cub; lost control on landing; performed a ground loop; departed the runway; powered across one ditch; avoided another and came to rest on a taxiway after scraping a wingtip. Minor damage and no injuries resulted.
