Narrative:

We were flying the razrr 4 arrival into sjc. While approaching the shikk intersection; norcal [approach] told us to expect the RNAV 12R. The first officer went to the departure/arrival pages on the FMC and selected the correct approach. I was on the legs page to make sure it was loaded properly. The first officer asked me if what he loaded looked ok. I responded 'no; it is not correct'; as there was a discontinuity after shikk. The first officer looked at the moving map display and saw magenta lines showing what looked like the correct routing. He executed the route even though I said it was incorrect. The autopilot reached shikk almost instantaneously and proceeded to fly straight ahead. I told the first officer to engage heading select and start a turn while I put in the intersection trcot. The first officer still did not realize that we had flown through shikk; so I started the aircraft in the correct direction and reloaded trcot. About that time; ATC asked if we were still on the STAR. I told ATC that we had flown through shikk and [we were] correcting. ATC told us to proceed direct ggugl. The first officer was too quick to execute the changes even though he was made aware that they were incorrect.
