I was thinking today about the skills that it takes to be able to analyze hockey properly, and it took me back to classroom learning. As somebody who hated memorization, it was always a relief to me when a teacher explained that we didn’t need to know something specific for the test. Providing a periodic table, or a t-table, or allowing us to write our own “cheat sheets” for a test was interpreted as a measure of sympathy by the professor. “I know this stuff is hard as hell; I’ll cut you a break and relieve you of a little studying.”
The truth, though, is that allowing the use of these materials, or going as far as holding open-book tests, has practical legs. In the real world, whether in science or math – really in most fields – it is more important to be able to find and interpret information than to know it offhand. If one needs to perform a chi-squared test, for example, in the internet age I can find that information very easily. The more experience one has in the field, the less one will need to rely on guides to perform such calculations, but until that point there is no need to hold information that can easily be found.
