Is this an American thing? We did absolutely not have to memorize any of that thing. We had to understand the structure, why the rows and columns etc. But memorizing it serves no purpose.
With every class including tests and exams we were allowed to use a reference book. This book was pretty thick and contained a whole lot of info including the periodic table and all the info about elements you could ever need.
I think my education (keep in mind this was 25 years ago) was focused more on the why and less on the what. If you understand why something is the way it is, the reason behind it and how to use it, you know a lot more than just being a flesh book that can list a bunch of facts.
It’s easier to verify rote memorization than actual understanding so naturally shitty schools focus on the former at the expense of the latter. Most American schools are shitty by academic standards.
While it is true that rote memorization is a terrible thing for schools to focus on, I find it interesting that the discussion immediately jumped to “America bad” with a presumption it was a unique American practice. The many comments from around the world show it seems to be a more widespread practice.
It’s American Exceptionalism at work. Unlike the rest of the world, we have no healthcare, we use Fahrenheit, and we put on our pants one leg at a time.
Czech here, also had to memorize it. But our school system here is 90% just memorizing shit, it’s a fucking joke.
In Lithuania we literally have the whole periodic table on the wall in every chemistry class I have ever been to.
Same in Hungary
And we have a book that you can use at every chemistry, biology, math and physics exam with a lot a formulas, glyph explenations, periodic table, material properties etc…
Memorizing the periodic table is probably the high-school assignment I’m most angry about to this day.
You didn’t have to memorize the Canterbury Tales?
I’d find that less-useless. You can’t reference the Summoner’s tale in 1 second.
I had to look up what the summoner’s tale was. I can say this from memory.
"Whan that Aprille with his shoures soote,
The droghte of March hath perced to the roote,
And bathed every veyne in swich licóur
Of which vertú engendred is the flour;
Whan Zephirus eek with his swete breeth
Inspired hath in every holt and heeth
The tendre croppes, and the yonge sonne
Hath in the Ram his halfe cours y-ronne,
And smale foweles maken melodye,
That slepen al the nyght with open ye,
So priketh hem Natúre in hir corages,
Thanne longen folk to goon on pilgrimages,
And palmeres for to seken straunge strondes,
To ferne halwes, kowthe in sondry londes;
And specially, from every shires ende
Of Engelond, to Caunterbury they wende,
The hooly blisful martir for to seke,
That hem hath holpen whan that they were seeke."
In America, we didn’t have to truley memorize it. For tests we had a reference packet that included the table.
That being said we did have to memorize a few major ones.
Its also important to recognize education is a state by state thing, not federal. The curriculum in Texas can be different than the one in Florida. Even teacher to teacher, I could see one class having to memorize it while the one next door doesn’t.
In my highschool we had an English teacher who was super into the Beatles. Like “the second half of the year was literally just learning about the Beatles and it made up like 60% of your grade”. I used to like listening to them but not so much after that year. To this day I don’t know how they got away with that
Binas in the Netherlands
It might be, I didn’t take chemistry in high school but those I know who did spent weeks memorizing it.
We were expected to memorize it, yes, along with the properties of each column and generally what went where.
But that was like the first part of chem, and after that test we had the table up on the front wall.
Are you talking about Binas? All the homies love Binas.
In my US chemistry undergrad program, we were required to memorize ~40 elements that were frequently used. We had reference material available to us in the test packets, but the test time given was so low that if you hadn’t memorized those elements, you didn’t have time to finish the test.
Our general chemistry class was one of the hardest classes you could take and much of the grading seemed unfair. Very minor mistakes that could propagate throughout your calculations would lose full points. There was never enough time for exams: you were expected to be very sure of how to run your calculations, there wasn’t extra time for you to be unsure or have to redo an entire question because you messed up. It truly sucked.
That said, it was very effective at graduating competent chemists. I didn’t trust any of the biologists, nurses, pharmacists, etc. to do even basic unit conversions unless they took that class. You can often tell well into someone’s professional career if they went through such a rigorous training program because many of the calculations and principles we learned in this class are ones we use daily. I run into PhDs in biology fields who don’t know the difference between molar and molarity, ones who are inconsistent at converting masses to mols, etc.
It’s embarrassing to reach that point in your career and lack these basic skills. I’ll hear, “yeah, but they aren’t chemists, so it’s not so important that they know these things.” If that’s so, then why do they need to do it as part of their job? Skills like these are agnostic to degrees and positions, it’s like learning basic arithmetic for most scientists.
I fucking hated that class and the professor for putting us through that, but that faded quickly with time. He made the rest of our education easier and prepared us well for the work that was ahead.
I agree with you. Though some people out there do really love being flesh books.

American here - we didn’t have to memorize it. All we had to do was know the groupings (Noble gas, metalloids, etc)
It’s a thing with some teachers in some places. The quality of education in the US is hugely variable, because standards and curriculum are largely left up to local school systems with widely different funding and priorities.
Brazil here, we had to, me and my friends even made some vulgar funny songs (to teenagers at least) to help memorize it, I had a pretty bad chem teacher.
We had the periodic table in huge letters on the wall of our chemistry classroom. Wouldbe difficult to not allow students to use it during tests.
One of my nursing school teachers used to say “You don’t have to know everything, you just have to know where to look it up.” I always thought that’s very good and practical advice.
Same.
So during the test the teacher listed element names out loud with no pauses, and you were supposed to write down the symbol while she was speaking, and then another list in reverse. After the last element we had to immediately put the pens down. Whole test took ~45 seconds for 30 elements.
This was so that it was impossible to read from the big table on the wall, you had no time to look away from the paper. You’d miss the next 3 elements by the time you looked away to find the one.
Honestly, that sounds insane. And incompetent.
Whoever made this a requirement did not have in mind to give you a good and useful education.Honestly, that sounds insane.
There is a reason I remember that one test many years later.
We had to memorize that entire fucking thing in highschool…
That’s stupid, who the fuck needs to know about antimony
Most chem PhDs don’t even know the whole thing lol. We had to memorize just the symbols in high school, but positions weren’t required. In my grad-level inorg course, the first test was a blank table that we had to fill in, but even then the f-block and transactinides were not required.
It worked so well I managed to retain that knowledge for almost a full week after we were tested on it lol it’s all gone now
I’m so glad Swedish schools have mostly ditched memorization (maybe too much sometimes though)
Teachers in the 90s: you won’t always have a calculator.
Me now: you were saying Ms. Knowitall?
That was a short answer that turned out to be mostly wrong. The longer answer is “if you don’t understand how this works, you won’t have the intuition to notice when you get absurd results from the calculator”. If you don’t have that intuition, then when you inevitably make a small usage mistake on a calculator (or in matlab or wolfram alpha or whatever), you’ll end up not realizing that you got a clearly wrong answer.
Just sing the Tom Lehrer Elements song
Lazy teaching
