Narrative:

Requested progressive taxi from ground control due to airport unfamiliarity. Clearance was to turn left on taxiway C and hold short runway 23. While taxiing I diverted my attention to set navigation radios to match our departure clearance. As I looked up the student was crossing a runway. I asked the student which runway and she replied that she had cleared the area prior to crossing but did not know which runway it was. Examination of the airport diagram revealed it was runway 23. I had the student stop, turn around and counseled her on the importance of reading airport signs and markings. I contacted ground control to apologize and explain the situation. To avoid this occurrence in the future, I'll maintain attention outside the airplane when in motion. No traffic conflicts occurred.
