  • The big thing is that vectors seem to be the kind of “shoved into the end of the semester if there’s time after testing” from what I’ve seen. Most of the time, even when I work with calculus students they have no idea what a vector is.

    A big thing to is getting them to understand what square roots even really mean. I’ve noticed a lot of students struggle with getting sqrt(x) * sqrt(x) = x, so even just the simple “hey, can you get a negative by taking a number and multiplying by itself?” is often a hurdle cognitively. (A lot of this I suspect has to do with not understanding what multiplication or division really “are” - I usually remediate with the area model)



  • Imaginary numbers are typically introduced in a high school “algebra 2” course in my neck of the woods, like junior year unless you are accelerated or held back. I feel like it’s really common for them to not be taught well - the naming is something that occasionally trips up the teachers.

    The teaching of them is something that really interests me - they’re the kind of thing that triggers the “when am I ever going to use this?”/rants about not learning how to do taxes. You can talk about the relevance to electronics, but DC electronics is already hard enough for most to comprehend.

    I like to connect it to rotation. Show them the pattern of powers of i with physical movement - quarter turns.


  • This is the kind of thing one thinks after injecting quite a bit of THC, but a conspiracy theory I half-believe in is that shit like Left Behind was a plot to mislead people so they wouldn’t recognize him when he showed up.

    So much of what your average white fundie/evangelical Christian believes about eschatology is not really in the Bible. It’s all mostly based on a Bible edition from 1917 plus John Bircher stuff - see the obsession with the United Nations. It can sorta be an anti Catholic church thing too, but fundiengelicals have mostly had a truce with Catholics since they formed their anti abortion coalition in the 70s (in the Left Behind series, the original pope does get raptured, but most media has the pope as either the anti-Christ or an eager collaborator)

    This is how they imagine the end of the world

    The Antichrist is a lefty who promises peace and tolerance and good things, so there’s nothing wrong with building a statue to this great guy, almost as persecuted and powerful as Jesus himself. Global warming is fake, really the sign of the end of the world is litter boxes for furries at school.

    Because they aren’t comparable and don’t belong in the same sentence honestly. The name is the same, genitals are getting mutilated, but one usually means a lifetime of pain and discomfort while the other usually means some loss of sensitivity.

    Female circumcision is done explicitly so that the girl will never experience sexual pleasure. No anesthesia, sometimes they rub animal shit in, sometimes they sew the vagina close to get forced open on the wedding night.

    Male circumcision is usually done in a hospital, and usually the intent is more something like thinking it prevents phimosis - which it might actually even be medically necessary in that case. It’s not done in a way to deliberately destroy function.


  • Also - don’t feel like you have to be a reading expert to help someone learn to read.

    The big big thing is phonics. If you can sound it out and have been speaking English your entire life, you’ve probably encountered the word by now. Of course there are a lot of obnoxious exceptions and patterns and rules but if you just start with slowly sounding things out with them you’re 80% there. We currently have a literacy crisis in the US in part due to a long discredited “whole language” model where children were deliberately not taught phonics, so this alone can be the miracle cure if there aren’t other obstacles (eg dyslexia, which is profoundly under diagnosed)

    Other big thing is finding things that catch their interest. It can be very hard to find material that is at a low literacy level but is also actually interesting to an older child/teen/adult. Comic books and manga are absolutely spectacular for this purpose because the pictures help support understanding - you can give them higher level material which will be more relevant to them. I read like I breathe because I read the Hobbit as a child and needed to up my game to get past “A Knife in the Dark” in Fellowship before the movie came out.

    The practical thing there - find books to read out loud with them that are compelling. Give them the fattest hit of how powerful the written word can be so that they’ll keep coming back for more. I always display subtle fandom swag or bring up a couple of popular phenomenons so I can recommend something they already like.

    I’m not a reading specialist - none of this is based on much formal training in that, but I am good at other pedagogy and have been in the position to need to teach all ages how to read.

    Helping teach someone how to read is one of the most profoundly good things you can do as a person, imho. You’re giving someone the tools to improve their life in so many ways. It’s honestly really fun to do as well.
