Human Factors
While approaching DEN on the KOHOE3 RNAV arrival; the ATIS reported ILS; RNAV or visual approaches in use. We setup and briefed the ILS 35R approach. After checking in with the second Approach Controller; we were issued the RNAV (RNP) RWY 35R. This assignment required a lot more cockpit workload; not to mention; this was the first leg of IOE for my First Officer. After loading the RNAV approach; I brought up the DOGGG waypoint on approach and executed. The legs page and the map magenta line looked correct. After the MSIMS waypoint; the route did not sequence to FRONZ; the aircraft continued downwind. Controller called us off course and issued vectors for visual approach.I really don't know what the setup error was as the magenta line showed radius leg to FRONZ. The DOGGG waypoint may have become the active waypoint and I did not catch it. This is the only reason I can think of. The late assignment to the RNAV approach caused high cockpit workload and I may have missed improper leg page sequencing.
ATIS provided three approaches and we selected the one which we thought would most likely to be used. DOGGG waypoint is on the KOHOE3 arrival and the routing on the bottom right of the STAR shows 'then as depicted to BARRK' which is what I believe the jet was trying to do even though on the MAP depiction showed otherwise. DOGGG is also the IF for the RNAV Z 35R.
B737NG flight crew reported ATC issued a new clearance when they deviated from the RNAV Z 35R approach to DEN.
