I just finished a program where I taught two classes of high school seniors, two classes a day for four weeks, as part of my grad program.
This experience was a lot of fun and it was rewarding, but it was really surprising, and even if only in small ways prompted me to update my beliefs about the experience of being a professor. Here are the three biggest surprises I encountered.
1: The Absent-Minded Professor Thing is Real
I used to be confused and even a little bit offended when at my meetings with my advisor every week, he wouldn't be able to remember anything about my projects, our recent steps, or what we talked about last week.
Now I get it. Even after just one week of classes, my short-term and long-term memory were both entirely shot. I would tell students things like, "send that to me in an email, otherwise I'll forget" because I would. Now that the program is over, things are slowly getting better, but I'm still recovering.
I can't really tell why this happened, but there are two obvious theories. The first is just that two classes at the same time is too many names and faces (plus other personal details) at once and so much information just overwhelmed me. The other is that there's something unusual about teaching in particular. I noticed that I was doing a lot more task-switching than normal. Most jobs and most of my research experience involves working on projects for long blocks of time, multiple hours or sometimes multiple days with few distractions aside basics like eating and sleeping and commuting. But teaching involves changing your focus over and over.
I've led recitation sections as a teaching assistant, but for some reason this was so much worse. That makes me think that it's more likely to be the task-switching. As a recitation leader, you have to remember a lot of names and faces too. But once you're outside of class you can mostly go back to work as normal, there's not so much task-switching.
This project was in a high school but my students were all seniors, so I think this is what it would be like to teach college too. Most of them were already 18 so you can barely tell the difference. I was helping them with projects so I think it's a bit like being a PhD advisor too. So it could also be the load of keeping track of lots of research projects, more than just keeping track of lots of people.
2: Teaching Makes You Dehydrated
For this program I taught only two days a week, just two classes, on Monday and Wednesday afternoon. But even with only two classes per day and two days per week, I became seriously and uncomfortably dehydrated.
This had all kinds of weird knock-on effects with my digestion and my ability to concentrate. It was really very unpleasant.
Part of this is that you have to be talking and meeting all the time. But mostly I got dehydrated because of the logistics. If you drink enough water, then halfway through the class you have to go to the bathroom and you're either super uncomfortable and distracted all session or you have to awkwardly walk out in the middle of class.
Even if it doesn't hit right away, a 10-minute break between classes isn't enough time to go to the bathroom, especially since some students show up early from the next class and others stay late. So you're trapped.
I had some success on days when I showed videos and could sneak out the back while they were watching. But overall this was bad for my teaching and my quality of life.
3: Teaching is a Grueling Job Even Under the Best Circumstances
I didn't really like high school. Classes were too easy and too boring, and even though no one was asking very much of me, I felt like I was being taken advantage of.
Implicitly I assumed that the teachers were the ones taking advantage of me, so even though they didn't seem all that happy, I assumed they were doing better than I was.
But in this program I still felt like I was being taken advantage of. But that didn't make any sense. I was teaching whatever I wanted (as long as it was roughly about the topic) and however I wanted. They didn't tell me what books to use or even ask to look at my syllabus. I made it as hard or as easy as I wanted. It was still really grueling, for me. Rewarding, yes, but grueling, kind of a pain.
This was the biggest surprise. I thought that school was mostly bad because teachers made it bad (skill issue?). But now I think there must be something inherent to school, or one of the assumptions we make about it (1hr 20min classes? class sizes?) that makes it a kind of miserable experience for all involved.
Looking back at this list, the final surprise is that these are all much more negative than I realized. Weirdly though this makes me more interested in teaching in the future. Maybe I can come up with new ways of doing things that won't make me so burnt out and distracted next time. I'd welcome any comments or suggestions. :)
Did the students really want to learn?
A few times I de facto taught a course on 'calculus with proofs' to a few students who wanted to learn from someone who seemed smart and motivated. I didn't get any money and they didnt get paid. We met twice a week. I could give some lectures and they discuss problems for a few hours. There was homework. We all took it very seriously. It was clearly not a small amount of work but I frankly found it invigorating. Normal classes were usually not invigorating.
I will say I found tutoring much more invigorating than teaching courses. When a student comes to you for tutoring they tend to REALLY wanna learn the material fast. Often there is a test coming up. They pay attention. If you are good they are grateful for your attention. And you feel grateful to them too! Its wonderful to see someone learn fast. Many students will be genuinely sincerely thankful to their good tutors. It makes sense the tutors were trying to help them learn as efficiently as possible!
I think teaching is soul crushing because neither the student nor the teacher is properly motivated. Teachers are not providing their students with optimal learning environments, they aren't even trying (where as a good tutor is actually trying. Even at a commercial tutoring center). And the students aren't trying all that hard to learn.
This is my usual conclusion but the issue is not lack of skill in most cases. Its lack of 'actually trying' and lack of 'minimal attempt at good practices'. Professors/teachers just have to teach whoever shows up and needs the class. This is true in tutoring centers too, to some degree. But in tutoring there is much more expectation students will find a tutor they vibe with.
Education could be fun and invigorating for both sides if both sides came into the experience with a sincere attitude to try. But unless goals are aligned where could such an attitude come from. And goals are often not aligned.
I will say as a professor I also wanted to help my students. But the obvious way to help them was to uhhhhh 'give them as high a grade as I could possibly get away with'. If I could id have given them all As but the amount of flexibility I had varied. But it was just too soul crushing to not go into teaching with a sincere desire to help my students not judge them.
This thread honestly reminded me I live in a college town. I wonder if anyone needs high quality help with their analysis or algebra classes. I could probably charge some reasonable rate and im a very good tutor if the student has the right vibe. and by right vibe I dont mean exceptional ability I just mean something like 'gets along with sapph as a person. Sapph is good natured but very high energy and clearly a little insane. Ideally the student finds this charming'
Yes, I often thought of this as a potential explanation before, but in this experience the students definitely wanted to learn. It was basically an elective and they're all seniors already on track to graduate, so they were under no pressure. They just wanted to learn! So in this case it wasn't soul crushing because the students weren't properly motivated, they were absolutely motivated, and so was I. In fact, I think it wasn't soul-crushing for the students. But it was still a little soul-crushing for me!
You absolutely should try tutoring! I'm sure you could find some students who are a good match and who would really appreciate it! :)
