Narrative:
First officer was PF, sat-iah. During this leg, center gave us a hold 70 mi out of R234, iah while were on the gland 7 STAR. We were approximately 13 mi from this point (not a charted fix) when we received the hold. I set raw data on my side and proceeded to assist the first officer in setting up a hold on the FMC. I was engrossed in helping this setup (and attempting to keep first officer's fingers from punching the wrong buttons) that I flew past the holding point. I notified ATC and quickly returned to the fix. We executed the hold via the now set up FMC, following it with raw data to ensure accuracy. First officer was unable to accomplish some important tasks relating to FMC work on the B737-500. My error was in attempting to 'teach' this first officer, rather than simply paying attention to the raw data and 'flying the airplane.'
