Human Factors
I was the instructor with a student training for a private pilot check-ride. The runway in use was Runway 30. My student entered mid-field left downwind for Runway 30 and made all appropriate calls. For example 10 miles out; 5 miles out; entering mid-field left downwind; left base; and final on the CTAF frequency. As we turned base another aircraft took off and was climbing out as we turned final. When my student was coming in; student was preparing to do a soft field landing. There was also active parachuting going on. When we were extremely short final the plane holding short of the runway made a call to say they were departing Runway 30 as we were coming down crossing over the threshold. They immediately started rolling toward the runway and I said 'Wait! Wait!' on the frequency. My student was starting the rounding out process and they immediately came to a stop just across the hold short line and said something about stopping on the frequency as we were touching down. I do not recall the call sign of the airplane that caused the runway incursion. We full stopped and taxied back and they departed. The aircraft was clearly not paying attention to our calls and either did not see us on final or did not look.
GA Flight Instructor reported an NMAC during final approach to DED non-towered airport after an aircraft crossed the runway hold short line before stopping.
