Human Factors
While in the traffic pattern at FDK; another plane that was cleared for takeoff and departing to the east; flew right into the traffic pattern that was in left pattern for the active runway. I was concentrating on the aircraft I was following on and maintaining separation from which is why I didn't see the aircraft coming.The aircraft came close enough that I could see the individual fins in the engine cowling. The pilot in question didn't realize he did anything bad.I had to pull power to idle; went partially weightless in the seat with the student; and approximately 45+ degrees pitch down in order to avoid the aircraft. I recovered at about 400 feet AGL before climbing back into the traffic pattern.There isn't really a chain of events here; or a complex swiss cheese model; this was a reckless pilot who disregarded scanning for other aircraft and nearly collided with another.I've personally had two ATC directed; and three total (including this one) near misses within 2-3 nm of the field at FDK.
