This is a report of a near miss at an uncontrolled general aviation airport.I am a CFII. I was doing VFR patterns at MNV airport with a pre-solo student. On the third pattern my student made a call 'final for Runway 23 Monroe County' as we rolled out on final. I then heard a call 'Baron XXXX final Runway 23 Monroe County.' I immediately asked the Baron for his position. The reply was '1 mile final.' I was inside 1 mile and stated that I was 'past the church' (a well-known landmark for the airport); thinking the pilot might know that reference. I honestly do not recall the exact reply; but it was to the effect of 'inside 1 mile.' I knew a Baron would be faster than my 70 MPH and would over run me.As I looked to my right I observed the shadow of an airplane on the ground. I did not consciously think it but did know that due to the time of day the shadows would be to the right of the plane; and the shadow was to my right.I immediately took control of the plane and made an aggressive correction to the left and down from my flight path. As I did so the light twin aircraft passed to my right; probably well within 200 feet. I continued to the left of the runway and flew a pattern to landing on Rw23. The twin was at the fuel pump. I asked the pilot what happened because I did not hear any calls prior to the one noting on final. He said he was sorry; and that he was on an IFR flight plan. I noted that did not change the requirement for radio calls for a VFR pattern. He noted that he had 25;000 hours (so what) I said 'I have 17;000; we should have done better.' I asked him if he had seen me. He said that his passenger saw me. I noted that if the passenger saw me then we were in front of him and below him and that we had the 'right of way.' He did not say the passenger made any verbal comment at the time.My student later commented that she thought she had heard calls for Morristown (not Madisonville; the local town) that seemed clearer that a distant airport usually made on the very common CTAF frequency. I admit I often hear only the first words/location of a radio call and do not concentrate on the rest of the transmission if it does not pertain to my airport. Several pilots in the area had observed the twin fly directly over the airport at something above pattern altitude then drop down into the downwind at pattern altitude. He must have been behind me at that time because I certainly did not see him on down wind and he would have easily out run my aircraft if he had been in front of me. Several of the pilots observed our aircraft in close proximity as he landed and I flew on alongside the runway; and later made comments about how close it must have been.Lesson learned is for any uncontrolled airport.1. I need to not get too involved in my instruction that I lose situational awareness of other aircraft.2. For aircraft on IFR into uncontrolled airports the communications to other NON-IFR is paramount.3. Fly the standard pattern so others know where the risk factors comes into play.
