Each Ninja Was A Different Kind Of Teacher (except Lloyd Who Basically Went On A Year Long Press Tour)

each ninja was a different kind of teacher (except Lloyd who basically went on a year long press tour) and it also explains why Rebooted and after they seem a bit more responsible than in season 1 and the pilot

Cole has my favorite teacher characterization because he's objectively an interesting person with cool hobbies but when he is responsible for a group of children he just becomes Dad Who Is Helping Out At The Summer Camp. we never see his classroom, but given his proficiency in the arts we can assume he's the English teacher

since he went to art schools, he's probably not used to kids who aren't actually interested in what's being taught. the louder kids seem to dislike him (ref: running gag of "Mr Cole is the worst"), but that doesn't mean he's necessarily a bad teacher- just not one to humor pranks

also his and Kai's teacher outfits belong in the 1970s. I like the touch of making their ties the same color as their gis

little bit of meta: most of the people who worked on this show went to school in the 80s/90s so to them "older/boring" teacher outfits would look like this. also, as someone who was in the intended age range and saw it at the time of release, this sort of clothing conveyed that the ninja were doing a stuffy adult job- juxtaposed with their colorful gis

Kai appears to be the history teacher? his teaching style is likely structured and straightforward. given his nontraditional childhood, his frustration with the kids likely comes from both his jealousy that they aren't aware of how valuable schooling is and that Nya was much easier to work with when she was their age. at the end of the day he's an older brother who's now in charge of a bunch of kids

he's using an old-fashioned projector with film, which I assume (1) shows how low-budget they are, (2) emphasizes that Kai is out of his element (pun not intended), and (3) juxtaposes them with New Ninjago City

Zane is the one who doesn't know what a vape pen looks like but will listen to you infodump for an hour after class, then drive/walk you home because you missed the bus. he probably doesn't get any of the classroom humor or notice if the kids make fun of him. I can't imagine him ever getting angry at the kids, and he probably is very good at keeping them to a routine and a schedule

in rebooted episode 1 he seems to be teaching science? and the use of catapults is actually quite endearing- he's probably explaining tension and going to get his kids to make little models, which shows that he both is a pretty good teacher and hasn't realized that giving elementary/middle/primary schoolers their own catapults will only lead to chaos

he and Jay have personality-based outfits, with the snowflakes being an obvious allusion to Zane's element and the zig zags on Jay's emulating lightning

the little bowtie on Zane reminds me of Bill Nye the Science Guy (program with a a host of the same name who taught kids about science in a fun and accessibly way- very nostalgic for kids who went to american public school)

Jay is the exhausted teacher who's more interested in his hobbies than class material, and if you get him talking about that hobby, he won't stop until the bell. as a jokester, I think he'd get along well with the kids and definitely encourage them to annoy the other ninja

we don't see his classroom, but given Jay's skills he's probably the math teacher. he'd have a difficult time explaining things in different ways- very gifted people who learn well on their own often find it hard to teach things to others, though he would make sure he doesn't leave anyone behind

Nya definitely teaches math classes, but she probably handles tutoring as well since she's well-balanced in most subjects. it would also give her an intelligence network- kids come to her room after class/during lunch to complain and gossip. she uses it in the noble pursuit to antagonize the others

i'm used this video and the ninjago wikia because I'm on mobile and finding other sources would've taken too long

extra group photo I found! love the detail that Zane blinked (Dr Julien probably took the photo)
