I wish this narrative that memorization is bad would die. Yes, understanding concepts is also important, but memorization is incredibly useful for learning and applying knowledge. The faster you can recall "trivia" the better you are able to make connections.
I say this as someone you drank the "no memorization" koolaid. Now I always start new things with memorization first and I learn so much faster.
Yep, the most obvious example (besides language) would be of math. Despite what kids (and unfortunately, some adults) say, it's worth memorizing the tables from 1->10 despite the ubiquity of calculators because the process of memorizing them helps with seeing the patterns that provide a deeper understanding, and it's much faster than pulling out a calculator and plugging the numbers in.
There are some subjects where the emphasis on memorization that some places have is detrimental, but that doesn't make memorization bad in general.
Doing math without memorizing some basic arithmetic facts is like reading without knowing what the hundred most common words in the English language mean, and having to look them up every time you encounter one. Sure I guess you can do that, but… you definitely shouldn’t.
As a kid, and probably still now, I was very reluctant to memorise things, for some reason I never understood but that may be connected with distrust of authority. I still remember how long and hard I fought my parents and grandparents who tried to make sure I would eventually memorise multiplication tables. Instead, I had to develop many tricks to be able to retrieve the proper results without memorisation, effectively discovering patterns to retrieve quickly all the tables from very few memorised numbers. Years later, I remember having done a similar thing in history classes, refusing to learn any dates, so instead finding tricks to tell which events must have occurred before or after another, thus again getting more engaged with the material as a result.
Sure, some material do require pure memorisation, like language learning (that I still hate with a passion), but overall I believe memorisation gets the bad rep it deserves.
