I’m quite taken with the Software Carpentry approach to teaching scientists computer skills, especially since I saw it in action in UW a few months ago. One aspect that I’ve been trying out for my own course is the “mastery table” approach that the Software Carpentry Instructor Study Groups use. Here is a mastery table for teaching version control. I have made a few of my own, but I don’t think I said enough for any novice to leave competent, according to my ambitions. I will keep trying.
