Narrative:

On approach to landing; my student and I were on the base leg to the final leg in the traffic pattern at payson's runway 6. There were two aircraft holding short of the runway and another two in the traffic pattern in addition to ourselves. As we made our report on CTAF that we were turning final for runway 6; a yellow and white cessna (unsure of exact model) appeared to be holding short of the runway we were using. As we were beginning our power reduction; we noticed that the same aircraft began pulling forward beyond the hold short line without a callout [stating] that he was taking the runway. This was happening as we were still in the process of our power reduction and flare. After we touched down and began our rollout; we missed the only taxiway turnoff that would allow us access to taxi back and clear the runway. Also; payson was under runway construction at the time and the only other taxiway that would allow us to clear the runway at the departure end of [runway] 24 was closed. Thus; we were required to make a 180 turn while on the runway to get back to the second; and only; taxiway exit. We announced our intentions on CTAF and began our turn around while we were just completing our landing rollout at a safe speed. As we were turning; we hear another aircraft in the pattern make a call to someone who apparently just took the runway with us still on the runway and said; '(inaudible) there is an aircraft still on the runway!' as soon as we hear this; we are just about completely turned around facing the departure end of runway 24 now and the suspect aircraft has begun his takeoff roll and rotates about 1;100-1;400 ft in front of us departing runway 6. As he rotates; he begins an immediate bank to the left; I take the controls from my student and we hug the left side of the runway and come to a complete stop to let the other aircraft clear us. As he clears us; he is about 35-50 ft above us and only about 100 ft in horizontal distance. We never heard a callout from that aircraft announcing he [was] taking the runway; nor did we hear any further callouts from that aircraft as he departed the traffic pattern. We taxied off the runway without further incident. After we cleared the runway; we noticed that there was fair number of spectators lounging around the hangers parallel to the runway who probably witnessed what had just happened. We taxied back to the departure runway 6 and remained in contact with one of the other aircraft in the pattern; who appeared to be the person who tried making the warning call to the conflict aircraft while we were on the runway. He wished us a safe flight home and we thanked him for his efforts. We departed pan without further incident.
