I've been teaching/tutoring people on how to program since my high school days. One of the best tools I've come to rely on is being able to show my student what the end result of the program looks like and how it behaves. Its often much harder for people to realize what you are trying to do with specific lines of code without having seen what the end goal is. Having seen the final result and working backwards along side you to figure out the bits and pieces that would be required to make the end result work is something far easier and more natural for people based on my experience.
