Does anyone use array data with the Universe teachpack? I thought it would be interesting to work with 2D data in an "advanced introductory" class. At least to the extent of being able to model classic board games like Battleship and Checkers.
This time we used math/array, but arrays are basically mutable in nature and that doesn't seem to work very well with way the universe is set up. My students ended up writing a lot of code like (begin (array-set! board ...) board) without really understanding it. Some copied arrays far too much and performance suffered, but I think that is a secondary concern. Is there a 2d data structure with functional updates that would be more suitable to this situation? I am aware of the possibility of abandoning big-bang for gui-lib, but I think that has its own minuses - it felt like I would need to teach too much about classes for it to work. Any suggestions or tales of relevant experience would be welcome. (Even "don't do that!" notes from people with more experience. :) Andrew Mauer-Oats CPS/Whitney Young Magnet High School -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
