I have asked the students to do a storyboard frame, a picture and short discription of what the program or sub-program is intended to do. It should list the inputs, outputs and actions. When a student asks me a question the first thing I ask to see is their plan. when advanced students do projects for teachers, I ask them to write a contract, or oppertunity evaluation in P+ terms. This is just an informal statement of what the program should do. Then they do the storyboards. I am currently doing this with Logo and plan to continue using the same process with Python.
