Human Factors
My student and I were entered the pattern from the west making 10; 6; 3 mile calls as well as downwind; base; and final calls. We were setup on final approach when a helicopter Aircraft Y called for takeoff at midfield. I immediately asked if the helicopter had us in sight with no response. The helicopter then pulled onto the runway without stopping at the hold short line. I made and immediate go-around and had to make a sharp turn to the right to avoid a collision. Other traffic in the pattern as well as ATC prior to our entry could hear our radios just fine as well.
C172 instructor pilot reported an NMAC event during final approach with a non-reporting departing helicopter traffic.
