Narrative:

7AC was doing landing practice and had been in the pattern for runway 34 for 3-4 circuits. Radio calls were being made to announce crosswind; downwind; base; and final on the CTAF frequency of 122.7. On this circuit; the bonanza had previously called that he was maneuvering for the downwind for runway 34. As the 7AC approached midfield on the downwind; the bonanza announced that it was entering the downwind for runway 34. He was headed directly at our aircraft; at our altitude. I took the controls from the student and made a right turn away from the bonanza. I asked him if he even saw us and he said; 'no.' he then stated that it was our problem that he did not hear us on the radio. I reminded him that this was a non-controled field that did not require a radio and that see and be seen were the safety issues. I reminded him that nonstandard entries to the traffic pattern required extra vigilance. He seemed disinclined to care.

Narrative: 7AC WAS DOING LNDG PRACTICE AND HAD BEEN IN THE PATTERN FOR RWY 34 FOR 3-4 CIRCUITS. RADIO CALLS WERE BEING MADE TO ANNOUNCE XWIND; DOWNWIND; BASE; AND FINAL ON THE CTAF FREQ OF 122.7. ON THIS CIRCUIT; THE BONANZA HAD PREVIOUSLY CALLED THAT HE WAS MANEUVERING FOR THE DOWNWIND FOR RWY 34. AS THE 7AC APCHED MIDFIELD ON THE DOWNWIND; THE BONANZA ANNOUNCED THAT IT WAS ENTERING THE DOWNWIND FOR RWY 34. HE WAS HEADED DIRECTLY AT OUR ACFT; AT OUR ALT. I TOOK THE CTLS FROM THE STUDENT AND MADE A R TURN AWAY FROM THE BONANZA. I ASKED HIM IF HE EVEN SAW US AND HE SAID; 'NO.' HE THEN STATED THAT IT WAS OUR PROB THAT HE DID NOT HEAR US ON THE RADIO. I REMINDED HIM THAT THIS WAS A NON-CTLED FIELD THAT DID NOT REQUIRE A RADIO AND THAT SEE AND BE SEEN WERE THE SAFETY ISSUES.
