Narrative:

Winds and traffic had the active runway at awo using runway 16. We were in closed traffic practicing takeoffs and lndgs with about 3 other aircraft. We were announcing our pattern positions on crosswind; downwind; base; and final on the local CTAF 122.7. During our 4TH circuit; we were taking off and at about 600 ft AGL met another low wing aircraft coming in on the localizer 34 approach. Neither I nor my student heard any call about the aircraft coming in on the approach. When we idented the hazard; we were in a dead head-on collision course. Evasive action was taken with no further consequence. I tried to contact the other aircraft; but he did not answer; nor did he report the missed approach. He disappeared in a westerly direction. I do not know if he was doing the actual approach (which is what it appeared to be) or if he was trying for a straight-in landing on runway 34; while being totally unaware of all the other aircraft in the pattern for runway 16.

Title: A HIGH WING LIGHT AIRCRAFT IN THE PATTERN AT AWO EXPERIENCED AN NMAC WITH A LOW WING AIRCRAFT ENTERING OPPOSITE DIRECTION TRAFFIC AT THE SAME AIRPORT.

Narrative: WINDS AND TFC HAD THE ACTIVE RWY AT AWO USING RWY 16. WE WERE IN CLOSED TFC PRACTICING TKOFS AND LNDGS WITH ABOUT 3 OTHER ACFT. WE WERE ANNOUNCING OUR PATTERN POSITIONS ON XWIND; DOWNWIND; BASE; AND FINAL ON THE LOCAL CTAF 122.7. DURING OUR 4TH CIRCUIT; WE WERE TAKING OFF AND AT ABOUT 600 FT AGL MET ANOTHER LOW WING ACFT COMING IN ON THE LOC 34 APCH. NEITHER I NOR MY STUDENT HEARD ANY CALL ABOUT THE ACFT COMING IN ON THE APCH. WHEN WE IDENTED THE HAZARD; WE WERE IN A DEAD HEAD-ON COLLISION COURSE. EVASIVE ACTION WAS TAKEN WITH NO FURTHER CONSEQUENCE. I TRIED TO CONTACT THE OTHER ACFT; BUT HE DID NOT ANSWER; NOR DID HE RPT THE MISSED APCH. HE DISAPPEARED IN A WESTERLY DIRECTION. I DO NOT KNOW IF HE WAS DOING THE ACTUAL APCH (WHICH IS WHAT IT APPEARED TO BE) OR IF HE WAS TRYING FOR A STRAIGHT-IN LNDG ON RWY 34; WHILE BEING TOTALLY UNAWARE OF ALL THE OTHER ACFT IN THE PATTERN FOR RWY 16.
