I was a TA for 6 years, I was a combo of Harsh Grader and (get this lab over with as soon as possible I have experiments to run). Surprisingly I was actually not hated....by everyone.
@Cole Clapperton actually modern journals are expecting passive voice only for established facts and active for your contributions so I’m gonna have to take off 5...sorry
I had the friend. He let me turn things in late, he had no safety rules except don't look directly into the laser, we ate breakfast in lab because it was early, and he babysat his kid during lab by just making sure the kid was shorter than the lasers haha.
He was the best. It was the only lab I could stand. And if one of our labs didn't work but another did, using the same exact shit, he was just like "well, that's what happens when you try to apply theory in the outside world. I'll look at it later."
I feel like that is what most men call it if they aren't stay at home dads lol. That's why I used it. He did. I'm not of the same opinion, but yeah lol.
"Just mention it and tell me what you would have done". That, along with all the real world factors I've been told to ignore in lab reports, is the most accurate description of lab work.
My personal favorite was "ok, let's do a Taylor series expansion of the math describing this lab set up...ok now just keep the first term" lab-magic lol
Lastly: The TA who kept everything from their undergrad and just copies what their professors did. Sometimes that's a good thing... sometimes it's not.
That's also what professors do. They don't really decide which teaching techniques they should use, they just copy what they saw as students. Which is why lecture still exists.
You forgot the TA that is fun and helpful and genuinely makes the lab enjoyable But then again i never had a TA like that in physics, so you were probably right to exclude them
AJ Voracek I like to think that of myself, but it’s pretty hard to make using a multimeter or oscilloscope fun to premed students lol.

@Another Random Cuber Cross products take two vector and it spits out another. It only works with 3d vectors. With 2 D vector it spits out the area of the parralelogram.(Basically like the determinant of a matrix) You can multiply a scalor by a vector, but its not called a cross product. When you calculate the center of mass, you can indeed multiplie the mass at a position by the position vector. Add all of these up. Divide by the sum of the position and you get the center of mass. Ps: you can't really divide vector by vector but here you would go component by component.
@Another Random Cuber moment of force is basically torque. Here you do rxF. r and F are vectors. The norm of the moment is ||r||* ||F||* sin(Angle betwern). If they are perpendicular, then its ||r||*||F|| What you said was almost right except theres a bit of a different. R is the vector going from the axis of rotation to the point where you apply the force. F is the vector saying how the force is applied. The moment is going to be in another plane because we detail rotations by their normal vector. Normal vector is perpendicular to the surface. If you would walk on that surface, the normal vector would go from your feet to your head. Lets say you have a helicopter then the R vector is basically the rotor blade.
This brings back memories. I was a physics TA for 3 years back in the 1990s. I generally received complements from students and high marks on the student evaluations. My first semester I got several "nice guy" comments on my evaluations. My last semester TA'ing something changed when I was neck deep in my PhD research and stressed out. I felt like I was teaching the same way as before but the positive comments were scarce. One student I had the prior semester that had high praise for the lab then, told me he wasn't enjoying the second semester. Maybe it was the student attitudes or maybe I was less talkative and in a hurry, or maybe both. I took this as lesson to remain enthusiastic during class, even when stressed out. I don't know if it makes a difference in how much students learn in a course, but I do think having a positive experience in a science class helps with lifelong learning.
A whole video that makes me even more self-conscious about being a TA and wondering what awful things my students are thinking about me. Thanks Andrew, very cool.
Ok, forget the definitions. Imagine a convolutional integral operator with r^n as the kernel, right, that's a discontinuous integral operator, but now apply it to a Dirac delta multiplied by your force. At this point, you get a finite value for every n. If you set n=1, you get your moment.

@@Hexanitrobenzene Meh, I didn't feel that bad. When I personally did the lab with the same equipment I got a .9999x. Obviously it's not fair to compare them to me lab skills wise, but we had all the equipment you needed to get really good calibration curves. You just have to take your time and read all of the equipment properly. And for what it's worth, empirically it did work (though low sample size). My classes had noticeably higher R^2s on the experiment that was design your own experiment except you're actually going to do what we want you to do because we don't have the equipment for anything else that could work. They still weren't great, but ~.93 was typical rather than the ~.88 other classes got.
All my engineering classes from the physics department had the best TAs. I just hope one day when I walk into one of my labs the first day I just see Andrew sitting there...
I once had a upper div linear algebra TA go all in on the theorist path, the guy told us all about basic group theory and about how you'd generalize linear algebra principles to different number spaces. We only spent a single week doing actual matrix stuff with real numbers. Honestly, one of the most fun TAs I ever had :)
I had the harsh grader TA and it was sooooo frustrating. Like we didn't do the assignment perfectly we got dinged. I also totally had the "just don't blow anything up and we're good" TA in chem labs, and he was so chill it was great
4:50 the music and the guy and the writing of a transformation rule via the Einstein summation convention and simple orthogonal rotations idea associated for a vector to define it is so awesome!!!!!
Most of my undergrad physics labs were a combination of "Never Comes Prepared" and "Experimentalist." I had one that had around 8 labs, and the TA never bothered to grade them until 5 days before the final. Never had I been more unsure about if anything I was doing was correct until that class.
Luckily none of my TA's have really been a problem (there was one that wasn't very prepared, but he was pretty good at working on the fly). When there was a problem, it was usually a problem with the course design, and the TA had to do what they could to compensate. I have, however, heard stories from other students going to other universities that roughly match all of these examples.
Someday I too will leave my little room where I spend the day studying and intead go to another dimply lid room to spend my day making fun of myself studying.
@@Hexanitrobenzene it was to lead into the sponsor of the video. It was making a sleeper agent/cell joke since he heard “great courses”, which led to a great courses plus ad
The first TA, ‘short lecture,’ is so accurate. We had three hours to finish the lab and he wouldn’t stop lecturing and we’d be rushing by end. The weird thing was with how long his lecture were, you’d assume he’d have answers to your questions but he never did
I once got 10 points taken off of one of my QFT assignments because I forgot a "-" sign, and to top it off, it was implied that I had done that maliciously to get the right answer, when in fact I purely forgot about it! :(
At my university at least, all physics grads are required to TA the first year (then if they don't have research funding they can TA subsequent years). It's not exactly something you apply for.
@@turtlellamacow At mine, you don't have to if you get an RA. It's just that, at least here, there's not enough funding for everyone to become RA's so only a few are able to get them, but they can get them right away.
That grad school grading comment got me. Decided to take a grad level structural geology course for 'fun' and came out with a C+. I was pretty worried about it until my advisor told me it doesn't matter and that I can easily explain it away if anyone asked about it.
Bro I had a TA that was hella cool. Our last lab was worth 50 with discussion. He emailed us a day before and told us that make sure everyone comes to discussion. So in discussion he told us that we are not doing lab today and he is gonna give us full points just for attendance. We were the only discussion class that didn’t do it. He told us don’t tell anyone lol. Those were the easiest 50 points. It was 15 people in that discussion. S/O Leo.
I woulda used it as at least a review session ya know. Like just give them the points for showing up but like they’re there already and so are you, and everyone’s schedule is cleared for it, so why not help prepare for the finals 🤷🏻♂️
“Imagine if you had a thing... and then there was a distance from the thing” I spend about 30% of physics 1 tutoring sessions saying some variant of this, I feel called out
I went to the grad school, 100% people who were with me went to grad school, of course you are here to go to grad school too, unless you are a freakish exception.
Marbles P I remember having a TA that was just the hottest woman Id ever seen. Unfortunately, this made me too scared to ever ask any questions or even....speak at all for that matter 😂
I've got the hyphenated last name passive aggressive mildly sexist against males with a slight tinge of a power trip TA. She's great. Gotta love when you get an eye roll asking a question about something you've never done before.
As much as I hate physics (bio major here), I have to say, I’ve been pretty lucky in that my physics TAs have been pretty good. In particular, my Electricity and Magnetism TA was absolutely lovely, super accommodating when something went wrong in the lab, very quick to respond to questions in emails, and very straightforward with the help he gave. At the end of the quarter after TA evals, he sent us all a very grateful message thanking us for saying such nice things about how he did :)
My physics lab ta was the best. My lab partner legit left on me, like dropped out of college. I wasn’t good at doing physics by myself when its two persons amount of work. He helped me in all of the assignments and I passed with a B. Love the guy
I just got my linear algebra midterm back, graded by a TA, and came right back to this video to comment about it. He graded it similar to "the harsh grader", but honestly it was more like "the unpredictable grader", essentially grades were strictly held to a standard, and that standard was completely unpredictable. Here are some places I actually got points taken off: One of the questions was to find one possible solution vector to a system of equations (there could have been multiple correct answers, we just had to give one). The question was worth 10 points out of 70 total points on the exam, I got 8 of the points. I set the problem up perfectly, I went through it perfectly, my work was clear and easy to follow, at the end I wrote "[vector] is one solution" and circled it, which was correct. So how did I lose two points? Because I simply said it was a solution but didn't say what it was a solution to. Seriously, the TA wanted me to say, specifically, that it was a solution to the equation presented in the problem, because apparently when I wrote and circled an answer it wasn't obvious that the answer I gave was the answer to the question asked and not some random other question. Another question was having us construct an augmented matrix from a system of equations and row reduce it to RREF. I actually did make a mistake in this one that justified losing some points. I'm not at all detail oriented as a person (thank God I'm not an engineer or programmer, I'd never survive) and when I copied the system of equations I miswrote 2 of the coefficients. Which means the augmented matrix I went to solve was different than the one in the problem. This got one point taken off, and that's fair. But then I correctly solved that augmented matrix and got 2 more points taken off because the answer to the question was wrong, but it was correct for the matrix I started with. Essentially I miswrote 2 coefficients, did everything else correctly, and got only 70% of the question. Other students received grading decisions just as pedantic. They would lose points for not writing an explanation that wasn't asked for or for writing an answer that was correct, simplified, and in the proper form but just not the particular correct answer the TA wanted. I've never even met this TA so I don't know what their deal is, but it's the most unfair grading I've ever seen, and this midterm is 25% of our final grade. It was so bad the professor actually seemed embarrassed. He said anyone who had questions about their grades could stay after to talk about it and literally at least half the class did. There were some instances of losing points that were so ridiculous he just flat out said that it was unfair and asked several students (including me) to leave our exams with him so he could look it over more and possibly change the grade, so I think my grade is likely going to go up over 5%.
I have had four lab TAs in various chemistry classes: 1: The Harsh Grader/Never Comes Prepared 2: Everybodies "Friend" (but he actually was everybodies friend in a good way) 3: Never Prepared 4: Lecturer
I'm not even in college (I live on a university campus though) and your videos are absolutely AMAZING, thank you TH-cam Recommended and Andrew for making these :))
bro the experimentalist one is crazy. my first e&m professor was actually an engineer (PhD on superconductors and superfluids and shit) and that is exactly how he acted lmfaooo. he's a great guy though but god that was funny
I still remember when my second year E&M TA tried to explain some mathematical concepts so quick that a lot of people seemed confused. It didn't take more than 3 tutorials to have majority (if not all) students to just stop attending or goes to the other TA's tutorial lmao. It's kinda sad, but I'd rather not waste my time on some TA I don't understand. The other TA is amazing, he explain each questions slowly and very clearly.
I was an econ major TA. The theorist one is my entire TA approach. That was scary accurate. You don't want to know what I was showing my poor econ 103 students.
I have to add one more type I've seen: The One Who Thinks He's Better Than the Professor. In my undergrad quantum class, one of the TAs would come to lectures and do work in the back, just so he'd know what we have and haven't covered in lecture. He was a super-engaged TA, taught me a lot of general relativity just for fun on his own time, and was a fantastic mentor to me. But that said, he clearly had some thoughts on how the class should have been taught better (and he wasn't wrong... just blunt). When the professor got done explaining the uncertainty principle in its full mathematical rigor, he asks if there are any questions. Only the TA's hand went up... and when we was called on, he whips out his laser-pointer and starts adding on to the professor's lecture from the back of the room with some other insight he thought we all needed to know. It was literal backseat lecturing. The professor had this look of "I am so done with you but I can't say anything in front of the undergrads."
I was the "Needs to give a short lecture every lab", "The Harsh Grader", and "The Theorist" type. So true 😂 The "Not even your TA" types are kind of annoying to me when I was TAing the lab but at the same time, they are also good because you got people to chat during the lab.
I can sort of be like that, but my students have always found it helpful to use analogies of things they're more familiar with. Perhaps there's good ways and bad ways of the "basically it's like."
I love the “basically it’s like” TAs. Most of the time when I ask questions I’m not asking them to recite a HARDCORE definition - I can find that in textbook - but a watered down, intuitive way to understand it. Sometimes analogies work wonders
I'm not a TA but an LA (I'm an undergrad) for a lab and...yeah I'm pretty much the one who never comes prepared but in my defense I already did all the same labs when I took the class last year I'm also the theorist. That bit at 5:38 was exactly me like ten times yesterday lol oops
It was a *Hell* on Earth when one of my math TA's found out that a poor devil in his class marked a homework problem solved on a list but couldn't show it on a blackboard!
This semester we had these two amazing TAs that basically carried the entire course because the teacher didn’t really teach us 💀 We really got lucky and I’ll miss having them as TAs :((
I had more of an older brother TA. Didn't really care if we made it or not, was picky about small things to us, but would be helpful when we asked and was on our side
Dude you nailed the acting. But you're forgetting the TA who is way better at teaching than the actual lecturer.
This is like every TA i ever had.

And for what it's worth, empirically it did work (though low sample size). My classes had noticeably higher R^2s on the experiment that was design your own experiment except you're actually going to do what we want you to do because we don't have the equipment for anything else that could work. They still weren't great, but ~.93 was typical rather than the ~.88 other classes got.
All my engineering classes from the physics department had the best TAs. I just hope one day when I walk into one of my labs the first day I just see Andrew sitting there...
“Mention this in your report and say what you would have done” hits different
You forgot the TA you can’t understand since he doesn’t know english
Once had a Chinese TA in a class who kept misinterpreting what I meant (and vice versa). Was pretty awful.
I had a combo of this and the theorist.... It was uh interesting.
They usually just correct papers.
😂😂😂
@Dayami Velazquez 6 weeks is like a week before exam 2 tho :/
Daddy Andrew has posted- my day is now perfect.
The TA that, when asked advanced questions, tells us it's complicated and we won't understand it when low key he doesn't know it himself.
Now I understand moments! Thank you Flannel Andrew

I once had a upper div linear algebra TA go all in on the theorist path, the guy told us all about basic group theory and about how you'd generalize linear algebra principles to different number spaces. We only spent a single week doing actual matrix stuff with real numbers. Honestly, one of the most fun TAs I ever had :)
I had the harsh grader TA and it was sooooo frustrating. Like we didn't do the assignment perfectly we got dinged.
I also totally had the "just don't blow anything up and we're good" TA in chem labs, and he was so chill it was great
2:45 : Me in EVERY experimental classes
4:50 the music and the guy and the writing of a transformation rule via the Einstein summation convention and simple orthogonal rotations idea associated for a vector to define it is so awesome!!!!!
Most of my undergrad physics labs were a combination of "Never Comes Prepared" and "Experimentalist." I had one that had around 8 labs, and the TA never bothered to grade them until 5 days before the final. Never had I been more unsure about if anything I was doing was correct until that class.
Luckily none of my TA's have really been a problem (there was one that wasn't very prepared, but he was pretty good at working on the fly). When there was a problem, it was usually a problem with the course design, and the TA had to do what they could to compensate. I have, however, heard stories from other students going to other universities that roughly match all of these examples.
Dietterich Labs haha yeah I’ve only had bits and pieces of each.
Someday I too will leave my little room where I spend the day studying and intead go to another dimply lid room to spend my day making fun of myself studying.
7:27 when the demon who posessed you for a month finally comes out
I didn't understand that one...
@@Hexanitrobenzene it was to lead into the sponsor of the video. It was making a sleeper agent/cell joke since he heard “great courses”, which led to a great courses plus ad
The first TA, ‘short lecture,’ is so accurate. We had three hours to finish the lab and he wouldn’t stop lecturing and we’d be rushing by end. The weird thing was with how long his lecture were, you’d assume he’d have answers to your questions but he never did
I once got 10 points taken off of one of my QFT assignments because I forgot a "-" sign, and to top it off, it was implied that I had done that maliciously to get the right answer, when in fact I purely forgot about it! :(
I'm gonna be a friend with Theorist, he's kinda cute & funny
Yup... I needed that today, my TA sucks and this video really sheds light on my current experience. Thanks!
Clearly Andrew had a TA that used that moment example cause he was pretty fixated on it 😂
I've only had one TA who wasn't the "Didn't prepare" one. She literally could not speak English. How did she ever become TA?
Probably forced into it because they had more spaces open that semester. 😂
At my university at least, all physics grads are required to TA the first year (then if they don't have research funding they can TA subsequent years). It's not exactly something you apply for.
Do we go to the same school?
@@turtlellamacow At mine, you don't have to if you get an RA. It's just that, at least here, there's not enough funding for everyone to become RA's so only a few are able to get them, but they can get them right away.
At my college the physics TAs were just grad students who didn't have a graduate adviser yet. Usually for 1-2 semesters.
“I’m here to sculpt your minds. I’m not your friend.” 😂😂😂 I died
I’m going to be a TA for an engineering class next semester.
Am watching this to make sure I fit in perfectly with the desired archetypes.
I'm the easily distracted TA, the one that is led off on a 10 minute tangent when someone asks a slightly out of scope question.
You forgot the “sorry, you’re gonna have to figure that out on your own”
That grad school grading comment got me. Decided to take a grad level structural geology course for 'fun' and came out with a C+. I was pretty worried about it until my advisor told me it doesn't matter and that I can easily explain it away if anyone asked about it.
My university is large enough where you can work there for 20 years and never meet someone from the same department...
Bro I had a TA that was hella cool. Our last lab was worth 50 with discussion. He emailed us a day before and told us that make sure everyone comes to discussion. So in discussion he told us that we are not doing lab today and he is gonna give us full points just for attendance. We were the only discussion class that didn’t do it. He told us don’t tell anyone lol. Those were the easiest 50 points. It was 15 people in that discussion. S/O Leo.
I woulda used it as at least a review session ya know. Like just give them the points for showing up but like they’re there already and so are you, and everyone’s schedule is cleared for it, so why not help prepare for the finals 🤷🏻♂️
So delighted to see a notification from the TH-cam physics god! Clocked on it straight away!!!!!!
I had one who was "Never Come Prepared" and "Drunk Off Power" combined for a lab.
Vampyricon Yeah that’s just called a hypocrite lol. Can’t have high standards for your students when you don’t have high standards for yourself
I had a TA that was a harsh grader and a lecturer... he was brutal
That ad transition was smooth as hell
"Never prepared" Yeah, that's me. Glad I'm not a lab TA any more.
“Imagine if you had a thing... and then there was a distance from the thing” I spend about 30% of physics 1 tutoring sessions saying some variant of this, I feel called out
I’m a finance student why am I even watching this
...because it's that funny that it transcends different fields of study :D
I get to start TAing this week on Zoom. Wish me luck.
Good luck
“This will not fly in grad school” who said I was going there
I went to the grad school, 100% people who were with me went to grad school, of course you are here to go to grad school too, unless you are a freakish exception.
You forgot about the hot TA, those are my favorite.
Marbles P I remember having a TA that was just the hottest woman Id ever seen. Unfortunately, this made me too scared to ever ask any questions or even....speak at all for that matter 😂
I've got the hyphenated last name passive aggressive mildly sexist against males with a slight tinge of a power trip TA. She's great. Gotta love when you get an eye roll asking a question about something you've never done before.
I was not expecting “The Theorist” and it made me spit my coffee out
As much as I hate physics (bio major here), I have to say, I’ve been pretty lucky in that my physics TAs have been pretty good. In particular, my Electricity and Magnetism TA was absolutely lovely, super accommodating when something went wrong in the lab, very quick to respond to questions in emails, and very straightforward with the help he gave. At the end of the quarter after TA evals, he sent us all a very grateful message thanking us for saying such nice things about how he did :)
6:58 Why does this happen in almost all of my classes??? It's like a battle of TA ego
X'D
Im going to college next year. Watching this genuinely frightens me of whats to come
"Its basically this thing that has a distance from this thing" should be a metaphor meaning idk how to explain it
My physics lab ta was the best. My lab partner legit left on me, like dropped out of college. I wasn’t good at doing physics by myself when its two persons amount of work. He helped me in all of the assignments and I passed with a B. Love the guy
Omg the “not even your TA” is so accurate 😂
Quite possible one of the best segues I’ve seen
Both of my E&M lab TAs were “basically it’s like”, no ones questions got answered lol
I just got my linear algebra midterm back, graded by a TA, and came right back to this video to comment about it. He graded it similar to "the harsh grader", but honestly it was more like "the unpredictable grader", essentially grades were strictly held to a standard, and that standard was completely unpredictable. Here are some places I actually got points taken off:
One of the questions was to find one possible solution vector to a system of equations (there could have been multiple correct answers, we just had to give one). The question was worth 10 points out of 70 total points on the exam, I got 8 of the points. I set the problem up perfectly, I went through it perfectly, my work was clear and easy to follow, at the end I wrote "[vector] is one solution" and circled it, which was correct. So how did I lose two points? Because I simply said it was a solution but didn't say what it was a solution to. Seriously, the TA wanted me to say, specifically, that it was a solution to the equation presented in the problem, because apparently when I wrote and circled an answer it wasn't obvious that the answer I gave was the answer to the question asked and not some random other question.
Another question was having us construct an augmented matrix from a system of equations and row reduce it to RREF. I actually did make a mistake in this one that justified losing some points. I'm not at all detail oriented as a person (thank God I'm not an engineer or programmer, I'd never survive) and when I copied the system of equations I miswrote 2 of the coefficients. Which means the augmented matrix I went to solve was different than the one in the problem. This got one point taken off, and that's fair. But then I correctly solved that augmented matrix and got 2 more points taken off because the answer to the question was wrong, but it was correct for the matrix I started with. Essentially I miswrote 2 coefficients, did everything else correctly, and got only 70% of the question.
Other students received grading decisions just as pedantic. They would lose points for not writing an explanation that wasn't asked for or for writing an answer that was correct, simplified, and in the proper form but just not the particular correct answer the TA wanted.
I've never even met this TA so I don't know what their deal is, but it's the most unfair grading I've ever seen, and this midterm is 25% of our final grade. It was so bad the professor actually seemed embarrassed. He said anyone who had questions about their grades could stay after to talk about it and literally at least half the class did. There were some instances of losing points that were so ridiculous he just flat out said that it was unfair and asked several students (including me) to leave our exams with him so he could look it over more and possibly change the grade, so I think my grade is likely going to go up over 5%.
Had a lab TA who spoke very little english... every time we asked him a question he would just laugh nervously and walk away.
Haha, that was one of the better ad transitions I've seen on TH-cam.
physics homework instructions unclear. turned in my energy drink and used napkin instead.
I have had four lab TAs in various chemistry classes:
1: The Harsh Grader/Never Comes Prepared
2: Everybodies "Friend" (but he actually was everybodies friend in a good way)
3: Never Prepared
4: Lecturer
I'm that "everybody's friend" TA 😂
Better than most of the alternatives :)
I'm not even in college (I live on a university campus though) and your videos are absolutely AMAZING, thank you TH-cam Recommended and Andrew for making these :))
bro the experimentalist one is crazy. my first e&m professor was actually an engineer (PhD on superconductors and superfluids and shit) and that is exactly how he acted lmfaooo. he's a great guy though but god that was funny
I still remember when my second year E&M TA tried to explain some mathematical concepts so quick that a lot of people seemed confused. It didn't take more than 3 tutorials to have majority (if not all) students to just stop attending or goes to the other TA's tutorial lmao.
It's kinda sad, but I'd rather not waste my time on some TA I don't understand.
The other TA is amazing, he explain each questions slowly and very clearly.
The TA that basically does the lab for u when u ask for help
I literally recorded that as well and must have missed it when I was editting...
I feel called out
I was an econ major TA. The theorist one is my entire TA approach. That was scary accurate. You don't want to know what I was showing my poor econ 103 students.
I have to add one more type I've seen: The One Who Thinks He's Better Than the Professor.
In my undergrad quantum class, one of the TAs would come to lectures and do work in the back, just so he'd know what we have and haven't covered in lecture. He was a super-engaged TA, taught me a lot of general relativity just for fun on his own time, and was a fantastic mentor to me. But that said, he clearly had some thoughts on how the class should have been taught better (and he wasn't wrong... just blunt).
When the professor got done explaining the uncertainty principle in its full mathematical rigor, he asks if there are any questions. Only the TA's hand went up... and when we was called on, he whips out his laser-pointer and starts adding on to the professor's lecture from the back of the room with some other insight he thought we all needed to know. It was literal backseat lecturing.
The professor had this look of "I am so done with you but I can't say anything in front of the undergrads."
I was the "Needs to give a short lecture every lab", "The Harsh Grader", and "The Theorist" type. So true 😂
The "Not even your TA" types are kind of annoying to me when I was TAing the lab but at the same time, they are also good because you got people to chat during the lab.
The “basically it’s like “ TA’s are hands down my least favorite
Blaize Guerra honesty I was one of them lol but what do they expect when they hire someone that barely got a B in the class 😂 🐸 ☕️
I can sort of be like that, but my students have always found it helpful to use analogies of things they're more familiar with. Perhaps there's good ways and bad ways of the "basically it's like."
I love the “basically it’s like” TAs. Most of the time when I ask questions I’m not asking them to recite a HARDCORE definition - I can find that in textbook - but a watered down, intuitive way to understand it. Sometimes analogies work wonders
The one that gives a "short" lecture every lab has been every one of my TA's for the last three years
I'm not a TA but an LA (I'm an undergrad) for a lab and...yeah I'm pretty much the one who never comes prepared but in my defense I already did all the same labs when I took the class last year
I'm also the theorist. That bit at 5:38 was exactly me like ten times yesterday lol oops
"The thing, and then... there's distance from the thing" is basically how moments were explained to me
It was a *Hell* on Earth when one of my math TA's found out that a poor devil in his class marked a homework problem solved on a list but couldn't show it on a blackboard!
I’m quite surprised Andrews getting so many sponsorship these days even though his channel isn’t that big . Congrats man 🎉
You should see how many I have to turn down because they're irrelevant to the channel lol. Thanks!
This semester we had these two amazing TAs that basically carried the entire course because the teacher didn’t really teach us 💀 We really got lucky and I’ll miss having them as TAs :((
I had more of an older brother TA. Didn't really care if we made it or not, was picky about small things to us, but would be helpful when we asked and was on our side
