Narrative:

Myself and my student were doing touch-and-goes in a PA28-140 at 7g0. We were making all calls and were the only ones in the pattern. A call was heard, 'C152 east of airport will be entering downwind.' at this time I was upwind turning crosswind. Coming out of this turn, the previously called traffic was at pattern altitude entering direct on downwind. To avoid collision with traffic, I dove down on my crosswind and allowed traffic to pass over me. For separation purposes, I did a right 360 degree turn and rejoined downwind. I questioned C152 pilot and he responded, 'I said I was entering downwind and I had you in sight.'

Narrative: MYSELF AND MY STUDENT WERE DOING TOUCH-AND-GOES IN A PA28-140 AT 7G0. WE WERE MAKING ALL CALLS AND WERE THE ONLY ONES IN THE PATTERN. A CALL WAS HEARD, 'C152 E OF ARPT WILL BE ENTERING DOWNWIND.' AT THIS TIME I WAS UPWIND TURNING XWIND. COMING OUT OF THIS TURN, THE PREVIOUSLY CALLED TFC WAS AT PATTERN ALT ENTERING DIRECT ON DOWNWIND. TO AVOID COLLISION WITH TFC, I DOVE DOWN ON MY XWIND AND ALLOWED TFC TO PASS OVER ME.
