Narrative:

Problem: near miss in traffic pattern with a lot of student pilots in the area and a controller not paying enough attention to movement of traffic. My student and I had been in the traffic pattern for several touch-and-goes already when the controller cleared a student pilot for takeoff for touch-and-goes in right traffic. We were in a C150 and had turned downwind and getting ready to level off at traffic pattern altitude when I looked to my right as the controller asked other traffic if they had us in sight. At this point it would have been too late if I had not looked to my right. The student pilot was in a C180 and was turning crosswind into downwind right into us. I abruptly nosed the C150 over to avoid contact. The other student did not see us until he was on our left, in the right downwind. Needless to say, this shook my student and I up quite a bit. I think it could have been prevented if the controller asked the C180 pilot if he had us in sight while he was on crosswind. Judging by the C180's climb performance and the lack of our C150's at this altitude, I knew there might be a problem, but I didn't see it until almost too late. If my student was soloing, there would have been a collision. He could not have seen the traffic very well simply because of where he was sitting -- in the left seat.

Title: INSTRUCTOR WITH SPI IN TFC PATTERN HAS NMAC WITH SECOND ACFT ON XWIND.

Narrative: PROB: NEAR MISS IN TFC PATTERN WITH A LOT OF STUDENT PLTS IN THE AREA AND A CTLR NOT PAYING ENOUGH ATTN TO MOVEMENT OF TFC. MY STUDENT AND I HAD BEEN IN THE TFC PATTERN FOR SEVERAL TOUCH-AND-GOES ALREADY WHEN THE CTLR CLRED A STUDENT PLT FOR TKOF FOR TOUCH-AND-GOES IN R TFC. WE WERE IN A C150 AND HAD TURNED DOWNWIND AND GETTING READY TO LEVEL OFF AT TFC PATTERN ALT WHEN I LOOKED TO MY R AS THE CTLR ASKED OTHER TFC IF THEY HAD US IN SIGHT. AT THIS POINT IT WOULD HAVE BEEN TOO LATE IF I HAD NOT LOOKED TO MY R. THE STUDENT PLT WAS IN A C180 AND WAS TURNING XWIND INTO DOWNWIND RIGHT INTO US. I ABRUPTLY NOSED THE C150 OVER TO AVOID CONTACT. THE OTHER STUDENT DID NOT SEE US UNTIL HE WAS ON OUR L, IN THE R DOWNWIND. NEEDLESS TO SAY, THIS SHOOK MY STUDENT AND I UP QUITE A BIT. I THINK IT COULD HAVE BEEN PREVENTED IF THE CTLR ASKED THE C180 PLT IF HE HAD US IN SIGHT WHILE HE WAS ON XWIND. JUDGING BY THE C180'S CLB PERFORMANCE AND THE LACK OF OUR C150'S AT THIS ALT, I KNEW THERE MIGHT BE A PROB, BUT I DIDN'T SEE IT UNTIL ALMOST TOO LATE. IF MY STUDENT WAS SOLOING, THERE WOULD HAVE BEEN A COLLISION. HE COULD NOT HAVE SEEN THE TFC VERY WELL SIMPLY BECAUSE OF WHERE HE WAS SITTING -- IN THE L SEAT.
