Probably the chief cause of devotion to rigidity of method is… that it seems to promise speedy, accurately measurable, correct results. The zeal for “answers” is the explanation of the zeal for rigid and mechanical methods.
But there is a kind of passivity, willingness to let experiences accumulate and sink in and ripen, which is an essential of development. Results (external answers and solutions) may be hurried; processes may not be forced. They take their own time to mature. Were all instructors to realize that the quality of mental process, not the production of correct answers, is the measure of educative growth, something hardly less than a revolution in teaching would be worked.

John Dewey on Open-mindedness…
Pause to think about this: “quality of mental process is the measure of educative growth.”
Play with it to realize that standardized tests can never measure true learning.
