Narrative:

I was cleared to land runway 11L at tucson international. I landed and was given instructions to turn right off the active runway and back taxi on the opposite runway, (runway 11R/29L) and hold short of runway 21. I taxied as directed, but I failed to hold short of runway 21. When I crossed runway 21 about halfway across, I noticed a cardinal aircraft touching down on runway 21. At that point, tucson tower advised of what I had done. The cardinal looked to be about 3000 ft away when I noticed him landing. I attribute this error to the fact that as I was back taxiing down runway 11R/29L, I was debriefing my student on how the flight went. I admit I got tied up in the debrief and inadvertently crossed runway 21. My student and I discussed my error and we both have learned how important it is to pay attention! I have learned the importance of runway safety and I can assure this will not happen again. I have since required that all my students complete the runway incursion awareness program.
