Narrative:

At dab airport, my student was given a clearance to taxi to runway 7L and hold short of runway 16. I (the instructor) must have missed the hold short clearance as my student read it back. We proceeded to taxi and my student did not hold short of the runway and I was not aware of the hold short clearance. Dab ground control called us to tell us to stop just as we reached the edge of the runway. We did stop just at the edge of the runway but by that time the tower had already told the aircraft on short final to go around.
