Narrative:
I was instructing a student in a cessna 172 who was performing touch and goes. This was our second flight for the day; and the winds began to increase in velocity so we were preparing for our second to last touch and go. On final; the airplane showed signs of windshear due to the shift in direction and increase in speed. Touchdown was a bit rough and erratic; and it seemed that the wind had shifted to a tailwind so ground speed was a bit fast at touch down. At the moment of touchdown; the student abruptly applied full left brake (but not right) causing it to lock up. After yelling at the student several times to maintain centerline and get off the brakes; the student still failed to release the brakes on the left main tire. While overwhelmed by the situation the student seemed to have omitted verbal instructions given to him. While attempting to take the airplane from the student and using control inputs to get the airplane back on centerline; the aircraft skidded off the left side of the runway knocking down a runway light. The airplane came to a stop in the area between the runway and adjacent taxiway. The left main tire had blown and the lower left cowling had been impacted by the runway light causing a dent. Communications were maintained with then tower and I requested maintenance to tow our airplane to the hangar where it could be repaired. The airplane was then shut down and we were met by airport operations who coordinated the tow of the aircraft.
