Narrative:
We were en route from iad to ric. We were told to expect the VOR runway 20. At the last min, we were vectored for the ILS runway 16. We attempted to comply but we were too high, so went missed. The controller apologized and told us to expect the VOR runway 20. We briefed the approach again when the controller told us to turn to 210 degrees. We turned to the right. He said he wanted us to turn left. He then vectored us for another approach VOR runway 25. He never specified that he wanted us to go the long way around to 210 degrees. It was more logical to turn right and both myself and the first officer didn't hear him say left turn. Also, he had us set up for 4 approachs, thus creating a high workload for us.

Title: MULTIPLE APCH ASSIGNMENT CHANGES CAUSE CONFUSION AND ACR MAKES A TURN IN THE WRONG DIRECTION WHEN VECTORED FOR MORE THAN 180 DEG TURN.
Narrative: WE WERE ENRTE FROM IAD TO RIC. WE WERE TOLD TO EXPECT THE VOR RWY 20. AT THE LAST MIN, WE WERE VECTORED FOR THE ILS RWY 16. WE ATTEMPTED TO COMPLY BUT WE WERE TOO HIGH, SO WENT MISSED. THE CTLR APOLOGIZED AND TOLD US TO EXPECT THE VOR RWY 20. WE BRIEFED THE APCH AGAIN WHEN THE CTLR TOLD US TO TURN TO 210 DEGS. WE TURNED TO THE R. HE SAID HE WANTED US TO TURN L. HE THEN VECTORED US FOR ANOTHER APCH VOR RWY 25. HE NEVER SPECIFIED THAT HE WANTED US TO GO THE LONG WAY AROUND TO 210 DEGS. IT WAS MORE LOGICAL TO TURN R AND BOTH MYSELF AND THE FO DIDN'T HEAR HIM SAY L TURN. ALSO, HE HAD US SET UP FOR 4 APCHS, THUS CREATING A HIGH WORKLOAD FOR US.
