Human Factors
I was instructing student in Aircraft X. We were on right downwind Runway 16 at BDN at 4;500 MSL.Aircraft Y pilot made a position call with him being 'on a 3 mile 45 for right downwind 16.' Shortly after that radio call was heard; my student observed the plane being adjacent 50 feet (+/-20 feet) to me at an angle; forcing me to do an evasive dive.I made a radio call after I made the evasive maneuver; that I will slow down and he can turn downwind.
GA flight instructor reported an NMAC during approach to BDN non-towered airport.
