Analysis, Part 6: Toy cars problem


The student can set up a proportion equation and solve it if she does not make a computational error. However, if an error is made, she would not recognize an inappropriate answer. When asked to estimate how many cars could be parked, she says 14 or 16 -- not a good estimate. Again her procedural orientation is evident and debilitating.
