Code Slow Finish Fast

Looking through student code today brought this quote to mind.

“I didn't have time to write a short letter, so I wrote a long one instead.” Mark Twain

Students are always in a hurry to write the code for programming projects. No matter how strongly I suggest they think about the problem and design their code most of them start coding right away. This often results is a lot of code where a small amount of code will work just as well if not better.

Often the techniques for less code require a bit more thought. Setting up a long set of if statements with a bunch of different variable names is tedious but doesn’t always require as much planning as setting up an array and loop solution does. Students are in a hurry so they take what they think are shortcuts.

Experience tells of course. My version of Whack A Mole (our current programming project) can be changed from 5 possible “moles” to 6 by changing one 5 to a 6. Some of my students would have to write, well let’s just say I don’t want to do the math.  We’ll go over the options during our next class. The theme will be to think more before starting to code though.
