Narrative:

During initial climb out from a touch-n-go student landing; I was flying the aircraft to execute the initial climb and turn to downwind for another practice landing for the student to provide the student a break during our multiple practice landings for this training flight. I had made a radio call of 'dayton wright brothers traffic; aircraft X on the go; runway 2; closed pattern;' shortly thereafter I was critiquing the student's landing and I heard another radio call made by one of the other two aircraft working the traffic pattern using runway 2. That radio call was something like; 'aircraft on final for runway 20; we're using runway 2.' I had not heard an 'on final' radio call for runway 20 by another aircraft; but the radio call cued me there evidently was traffic on final for runway 20. I lowered the nose of my aircraft and immediately saw another aircraft that I perceived was inside 500 ft. From our aircraft and flight paths were leading to a mid-air collision. I immediately took evasive action; making an aggressively executed steep bank right turn of approximately 90 degrees of turn to deconflict our flight paths. After making the turn; I rolled back to the left and saw aircraft Y continuing its descent to a landing on runway 20. Three aircraft were conducting training flights in the traffic pattern for runway 2; and had been doing so for some time; at a minimum the entire time aircraft Y was on final for runway 20. Contributing factor to this event was the student training occurring inside my cockpit. Aircraft Y either never heard the multiple radio calls by the aircraft working runway 2 or disregarded the fact runway 2 was being used by the other aircraft in the pattern. From the human factors perspective; I accomplished the evasive action based upon an instantaneous assessment of the closure rate and angle of my aircraft to aircraft Y; subsequently perceived our mid-air collision potential; and the need to aggressively maneuver to avoid the collision.
