Narrative:

On descent into denver we did our checklist and our approach briefing. We contined into denver with numerous heading changes. We were cleared for the approach and told to increase our rate of turn because of a late turn onto the localizer. We flew through the localizer. This is when I realized we had a problem. My first officer, who was flying, had either not dialed in the inbound course at the approach brief or had turned his course needle to one of our numerous headings. This lead to a very unstabilized approach as he read the wrong inbound course. By the time we realized the problem the tower was breaking us off the approach and turning us to a 260 degree heading and told us twice to expedite to 9000', then given us another heading. I took the aircraft from the first officer when I saw he was 300' above 9000'. I don't know if he exceed 9300'. But we regained altitude and went around for another approach west/O further incident. I know the main problem was the incorrect course, however, the late turn on made things happen very fast and by the time I realized the mistake we were too far out of shape. The later headings and altitude flustered my first officer who is relatively new in the aircraft and I had to take over. Supplemental information from acn 140943. The captain and I briefed and configured for the ILS 36 approach. As we neared the airport we descended as instructed by the controller to 8000'. As we approached within 15 mi of the airport we were told to expect the ILS 35R approach. We changed frequencys and in the confusion I reset the course selector to the wrong course. We were on vector heading of 300 degree and this is where I had set the course selector.

Narrative: ON DSCNT INTO DENVER WE DID OUR CHKLIST AND OUR APCH BRIEFING. WE CONTINED INTO DENVER WITH NUMEROUS HDG CHANGES. WE WERE CLRED FOR THE APCH AND TOLD TO INCREASE OUR RATE OF TURN BECAUSE OF A LATE TURN ONTO THE LOC. WE FLEW THROUGH THE LOC. THIS IS WHEN I REALIZED WE HAD A PROB. MY F/O, WHO WAS FLYING, HAD EITHER NOT DIALED IN THE INBND COURSE AT THE APCH BRIEF OR HAD TURNED HIS COURSE NEEDLE TO ONE OF OUR NUMEROUS HDGS. THIS LEAD TO A VERY UNSTABILIZED APCH AS HE READ THE WRONG INBND COURSE. BY THE TIME WE REALIZED THE PROB THE TWR WAS BREAKING US OFF THE APCH AND TURNING US TO A 260 DEG HDG AND TOLD US TWICE TO EXPEDITE TO 9000', THEN GIVEN US ANOTHER HDG. I TOOK THE ACFT FROM THE F/O WHEN I SAW HE WAS 300' ABOVE 9000'. I DON'T KNOW IF HE EXCEED 9300'. BUT WE REGAINED ALT AND WENT AROUND FOR ANOTHER APCH W/O FURTHER INCIDENT. I KNOW THE MAIN PROB WAS THE INCORRECT COURSE, HOWEVER, THE LATE TURN ON MADE THINGS HAPPEN VERY FAST AND BY THE TIME I REALIZED THE MISTAKE WE WERE TOO FAR OUT OF SHAPE. THE LATER HDGS AND ALT FLUSTERED MY F/O WHO IS RELATIVELY NEW IN THE ACFT AND I HAD TO TAKE OVER. SUPPLEMENTAL INFO FROM ACN 140943. THE CAPT AND I BRIEFED AND CONFIGURED FOR THE ILS 36 APCH. AS WE NEARED THE ARPT WE DSNDED AS INSTRUCTED BY THE CTLR TO 8000'. AS WE APCHED WITHIN 15 MI OF THE ARPT WE WERE TOLD TO EXPECT THE ILS 35R APCH. WE CHANGED FREQS AND IN THE CONFUSION I RESET THE COURSE SELECTOR TO THE WRONG COURSE. WE WERE ON VECTOR HDG OF 300 DEG AND THIS IS WHERE I HAD SET THE COURSE SELECTOR.
