This occurrence happened when landing on runway 23 the student was flying the plane and I (the instructor) was following along with the controls. There was a left crosswind condition. The exact velocity is unknown; but is guessed to be around 10 KTS with gusting probably to 15 KTS. On short approach I helped the student put in the proper crosswind corrections. Upon reaching ground effect; I helped the student land the airplane. Upon landing; I suspect the student pressed on the left rudder to straighten the plane out; but pressed the rudder with too much force. This caused the plane to yaw too much to the left and the plane was in a side-loaded condition. The right wing dipped towards the runway and the left main wheel came off the ground. I immediately took over the controls and got all wheels back on the ground. The airplane at this point was facing approximately 45 degrees to the left of runway heading. Instead of trying to aggressively steer the plane back onto runway heading; I felt it was safer to continue going straight into the dirt off the left side of the runway. I continued until reaching the taxiway running parallel to the runway. I then parked the plane; shut it down; and did a visual inspection for any damage. No damage was found and the plane was then started back up and flown to my home airport.

Title: A PA28 INSTRUCTOR PLT RPTS A RWY EXCURSION AFTER TAKING CTL AS THE ACFT YAWED BECAUSE OF A STUDENT'S INCORRECT RUDDER INPUT DURING A XWIND LNDG.
Narrative: THIS OCCURRENCE HAPPENED WHEN LNDG ON RWY 23 THE STUDENT WAS FLYING THE PLANE AND I (THE INSTRUCTOR) WAS FOLLOWING ALONG WITH THE CTLS. THERE WAS A L XWIND CONDITION. THE EXACT VELOCITY IS UNKNOWN; BUT IS GUESSED TO BE AROUND 10 KTS WITH GUSTING PROBABLY TO 15 KTS. ON SHORT APCH I HELPED THE STUDENT PUT IN THE PROPER XWIND CORRECTIONS. UPON REACHING GND EFFECT; I HELPED THE STUDENT LAND THE AIRPLANE. UPON LNDG; I SUSPECT THE STUDENT PRESSED ON THE L RUDDER TO STRAIGHTEN THE PLANE OUT; BUT PRESSED THE RUDDER WITH TOO MUCH FORCE. THIS CAUSED THE PLANE TO YAW TOO MUCH TO THE L AND THE PLANE WAS IN A SIDE-LOADED CONDITION. THE R WING DIPPED TOWARDS THE RWY AND THE L MAIN WHEEL CAME OFF THE GND. I IMMEDIATELY TOOK OVER THE CTLS AND GOT ALL WHEELS BACK ON THE GND. THE AIRPLANE AT THIS POINT WAS FACING APPROX 45 DEGS TO THE L OF RWY HDG. INSTEAD OF TRYING TO AGGRESSIVELY STEER THE PLANE BACK ONTO RWY HDG; I FELT IT WAS SAFER TO CONTINUE GOING STRAIGHT INTO THE DIRT OFF THE L SIDE OF THE RWY. I CONTINUED UNTIL REACHING THE TXWY RUNNING PARALLEL TO THE RWY. I THEN PARKED THE PLANE; SHUT IT DOWN; AND DID A VISUAL INSPECTION FOR ANY DAMAGE. NO DAMAGE WAS FOUND AND THE PLANE WAS THEN STARTED BACK UP AND FLOWN TO MY HOME ARPT.
