The local instructional flight departed Oakland about 1030. Visual meteorological conditions prevailed and no flight plan was filed. The operator reported touch-and-go landings were practiced for approximately 1 hour, and the winds were variable. After power was added and the airplane was accelerating, the instructor noticed the student was not compensating for torque or crosswind. The instructor prompted the student to add right rudder, but the student reacted quickly with left rudder and brake. The instructor, who assumed control, pulled power but did not want to make aggressive control inputs due to the airplane's speed. The airplane veered left, departed the runway, and hit a runway light. The nose gear collapsed and the firewall buckled.
