If a teacher is instructing students to copy a drawing, and re-copy it over and over using various tools like pencil, markers, crayons et al, that is operant learning, no matter what the goal is, as in Melissa's situation; teaching "perserverance."
The biggest draw back is the lack on personal participation; individual creativity; imagination.
I think "perserverance" should be developed from the inside out so that no matter what the task, or the desire, the person, will "perserve"...not just copy something of someone elses design over and over...that seems more brainwashing.
Parents can participate by having their child do this at home if the teacher does not provide it, so the child can learn the difference.
