Human Factors
We were doing traffic pattern operations and Aircraft Y joined the pattern. Due to the runway being short we were doing land and taxi backs. On our second to last landing we were taxing back to the taxi via the runway. During this time Aircraft Y called short final. I took controls from my student and expedited the taxi. We cleared the runway with only about 5 seconds before touchdown. Aircraft Y cleared the runway behind us and departed shortly after us. As we were in downwind Aircraft Y said that he was number two following the Aircraft X. As we landed we heard him calls for a final again. When we turned around to back taxi Aircraft Y was already in his round out to flare. I directed the student to get to the right side of the runway. This gave us the most room from Aircraft Y since he was not going to go around and we did not have a safe place to clear the runway. As he can just stop he turned off the runway and got in front of us to taxi back to the hanger.During this incursion I believe the main cause was decision making process. Even though the runway is 200 ft wide there should not be two airplanes on the runway. I believe Aircraft Y thought that with that being 200 ft wide that he'll be okay landing at the same time we were taxiing back. He also did not use his radio to tell us what his plans were.
A Flight Instructor conducting training at a non-towered airport reported they back taxied on the runway after landing two times causing a near collision with a trailing aircraft which was landing and had reported on final approach behind them.
