Nice article! I guess it's obvious in retrospect, but I hadn't known of all the systematized study devoted to this topic. I'm happy to learn about it because I've found myself thinking about effective teaching and learning pretty often (I'm an academic), and what to do about "the stuff where, when you try to explain it concretely to someone else, your explanation doesn't really make sense unless the other person already knows what you're talking about". In subjects I've tried to learn and teach, my experience is that talking to someone with a lot of such knowledge really only gives you an idea of the sub-topics and considerations you should try to understand better on your own. It is helpful in narrowing down what you should prioritize and maybe giving you a useful point of view to organize your thoughts from, but that doesn't save you from doing the thinking and understanding for yourself. I agree that emulation helps somewhat by forcing you to make choices that are reasonable even if, as a beginner, you lack the knowledge to choose wisely yourself. But if the ultimate goal is to come up with new ideas using the knowledge, I think there's such a thing as too much emulation. You don't want to become a carbon copy of your mentor either. I agree that deliberate practice and acquiring tacit knowledge are not the same thing. To me, deliberate practice is about repeating a certain activity -- one that you typically can describe in words to someone who doesn't already know it -- enough times that it's available to you as a tool, eg playing scales as a musician, times tables in elementary school math. Tacit knowledge has more to do with how you decide to apply those skills to best effect. But my experience has been that they have kind of a symbiotic relationship. If you didn't have some tacit knowledge to begin with, you wouldn't know what to practice, or when you had practiced enough to be good. At the same time, it may not be possible to acquire enough tacit knowledge to become an expert if you don't have an immediate command of certain skills developed through deliberate practice. I.e. there's feedback -- more tacit knowledge should make your deliberate practice more effective, and better skills make it easier for you to acquire tacit knowledge. |
