Human Factors
While inbound to CKN my student and I overheard multiple aircraft on their way to CKN. There was one aircraft on a 10 mile final for 31 low approach; another aircraft overflying at about 3000 feet; then a warrior operating north a few miles out for runway 13. There was also a garbled radio call which I couldn't make out. We proceed outbound to make left traffic for 13. The warrior landed and got clear of the runway; and the aircraft overflying the airport overflew it. We were now base to final making radio calls as we go along and coming in for a landing. On upwind we made a radio call and proceeded to the downwind. On downwind we made another call. The other aircraft for 31 was now two miles out on final. This is where someone on the ground made a radio call and stated that there was an aircraft about our same position. We looked around and saw an aircraft that was lower; at our 2 o'clock position and within 500 feet. I took the controls and turned towards base to exit the traffic pattern and made a radio call telling the aircraft on a 31 low approach he had someone coming the opposing direction. I didn't hear a radio call from this aircraft so I'm assuming they we having radio problems.Maintaining situational awareness in the traffic pattern and scanning more often would be a corrective action because not everyone can be communicating.
A flight instructor and his student suffered an NMAC with another aircraft in an uncontrolled airport traffic pattern.
