As we industrialized learning and created schools, we needed to measure the system’s efficacy and each child’s progress. What you really want to measure is curiosity, imagination, passion, creativity, and the ability to see things from multiple points of view. But these are hard to measure other than one on one, and even then, the assessment will be subjective. So instead, we measure what a child knows, and from that we infer that the child has learned how to learn. This is the real aspiration we have for our children: learning learning.
