efp asks: "I'm a graduate student and have a programming assignment coming up. We're encouraged to work in pairs and I've agreed to work with a friend. However, while I'm far from l33t, I've several years more experience than my partner. Are there effective techniques for pair programming with a wide gap in talent? I want us both to get a lot out of the assignment, and I do not want to do all the work (which has been specifically identified and disallowed by the instructor anyway). Navigator/driver scenarios? Index-card design techniques?"
