Human Factors; Procedure
I was conducting a training flight with two students. We were practicing landings with traffic patterns. We were constantly reporting our position (each pattern leg) on CTAF frequency. An aircraft reported on CTAF frequency 5 miles north of the field and reported intention to enter left downwind runway XX. We were on the upwind; turning crosswind of runway XX when [Aircraft Y] entered direct downwind; crossing the extended centerline of runway XX and crossing our path 30 ft. from us without reporting. I had to take controls from my student and take an evasive action pitching down to avoid collision. It didn't seem like the pilot of the aircraft was looking outside as he didn't see us right in front of him slightly below. The pilot of [Aircraft Y] didn't enter at 45 degrees to the downwind as recommended in AIM for uncontrolled airports creating a hazardous situation that might have resulted in mid air collision and didn't report his position so that traffic in pattern (us) could look for him. I have 2 students that were witnesses to this.
Tecnam P2006T instructor reported traffic making nonstandard traffic pattern entry; resulted in a NMAC.
