Narrative:

Upon landing the student input the incorrect rudder trying to bring the aircraft back to centerline. After a verbal reminder of which rudder to use; I forcefully tried to take over the aircraft. At this point we were traveling 15 degrees off the runway. I attempted to input the corrective rudder action and found myself flighting the student for control of the rudders. We ended up running off the left side of the runway into the grass for around 100 ft. At that point; I was able to regain control and brought the aircraft back onto the runway.
