What students get wrong when building computational physics models in Python: Cabellero thesis part 2 « Computing Education Blog: "Danny suggests that these were physics mistakes.  I disagree.  I think that these are computation, or at best, computational modeling errors.  Many students don’t understand how to map from a situation to a set of constants in a program.  (Given that we know how much difficulty students have understanding variables in programs, I wouldn’t be surprised if they don’t really understand what the constants mean or what they do in the program.)  They don’t understand Python’s error messages, which were about types not about Physics."
