The reading and the math concepts for elementary school students aren't the only things I think this can apply to. How many people here can see the translations for new sets and memorize each individual card's attacks, powers, bodies, and HP with that one look at them? It has been several months, or even over a year, since I have even glanced at a set list for DP through GE, but name any card in one of those sets and I can recite its attacks and its powers/bodies almost word for word. It only recently dawned on me how incredible that is considering that it has been an ordeal just memorizing polyatomic ions and solubility rules for chemistry. It seems like a similar case as the one described in the article with the dopamine. A motivated mind just functions more efficiently and effectively than one that isn't. I'm thinking of making up proxies of trading cards for polyatomic ions to keep with me like a deck and I will be able to recall any little property about them I want to. For instance, I could put down "redox reaction" as a power of permanganate and dichromate. I think, if you wanted to put in the work to make all of those cards up, it could function as a tool for memorizing all kinds of information like state capitols, geography, US Presidents, multiplication tables, the unit circle, the 40 or so algebraic formulas you would learn in a typical physics class, electronegativities, standard reduction potentials, and tons more. What do you think?
