Would you feel more or less confident traveling on an airplane with one single gauge? (How could the engineers and pilots even contemplate narrowing it down to a single gauge? – That’s crazy!) The human brain and the process of learning are much more complex than these machines, yet in schools we mostly measure learning with a single gauge dashboard.
