I went back to uni after a 15 year career writing software. I attended the all the office hours for all my classes. Instructors went from shocked to excited, and I learned so much!

I think 18-24 is just way too young for most people to study at a university (at least math/physics-based ones). I don't have a better solution, but only about 6-7 years after graduating I realized I would then have enjoyed these classes and learned from them much much more.

I don't think it's an age thing, just maturity.

A type of maturity that develops much more slowly while being in the education system.

It sounds very lofty, but also on a path to disappointment and burnout. You can't meet the needs of all students. Fortunately, your class is small, but even there you find that you can't please them all (let alone a class of 300). And I write "please", because that's what you appear to be aiming at.

First, a course is there to convey knowledge and skills, not to please students. I'm not fond of hard rules in education, but some are simply right. Rule number one is: set the levels in advance: determine prerequisites and end goals. You may accept students outside the range, but it's their risk to take a class that's too easy or too hard, not your responsibility to overcome. You could always split it into multiple classes (basics and advanced), but that's already setting yourself up for more work.

Second: try to use literature, books or articles, for material that takes too much time in class. It's better that they come with questions than that they leave with questions. However, I'm aware this doesn't work well, since students don't read before class.

Third, I'm not teaching anymore, but my former colleagues and friends who teach and even direct programs, tell that the flipped classroom isn't only a nebulous concept, it also doesn't work. Covid has shown that. Developing a technically complex class that actually works is going to be very, very time consuming, and not rewarding at all. Cynically: when the department finds out you're not actually physically teaching, they'll assign you to something else. Or give your class to someone else.

Fourth, try to be interactive in class: explain, then give short, direct assignments. Your topic is unfortunately too complex to do anything meaningful during class, but perhaps you can ask them to look at some code and write down what it does, compare two different position evaluators, find out why a certain move can't be returned by a certain algorithm, etc. The trick is to get them to actually work out and write down answers (and it can be wrong; there should be no scoring for these exercises), not wait for someone else to tell them, whether it's you or the bright, interested student who's going to pass anyway. Everyone should apply their full attention to the problem for a short time.

Another cynical remark: it seems you're interested in knowledge transfer. You don't get high ratings for that. If your school evaluates teachers based on student feedback, it's a losing game. The only thing left, if you want to stay in that game, is to make it "fun."

A big problem (from my experience) is the cultural shift from high school to university. Our high schools do a terrible job at preparing students for college. Just off the top of my head: - High school classes are typically too easy - So kids develop poor study habits which don't serve them well for college material - And most high school teachers are bad at getting kids excited about the subject because they're exha…

> High school classes are typically too easy

The UK based O/A system, which is used in many of the former colonies, is not as easy as the North American high school system. O levels is easy. But A levels content is almost as difficult as a typical first year university course.

Yet, students from those systems also face an equivalent huge shock when they switch to university. The reason is fundamentally different. In school, students are infantalized and their own education is not considered their responsibility. In university, nobody used to care whether you sank or swam. So students struggled. But that has changed quite a lot now. Many universities have almost a "no child left behind" policy - yes they do think child not adult who chose to attend university.

So even if students in the past used to attend office hours (I don't know), today they don't because it is no longer their responsibility to learn.

> Flipped classrooms are popular these days, so I might try that, but I also feel that pre-recorded lectures are a little soulless. I might try a hybrid approach, integrating lectures with assignments.

My Physics I class in college was a bit of both. First part of class was lecture, then we did practice assignments in class as groups, then there was out-of-class lecture videos and assignments. The out of class lectures weren't very long, I'd say under 20 minutes per lecture day if memory serves. Just long enough to cover a small topic in enough detail.

I enjoyed this article. A couple of points, if the interactive/handson way is the future, how do we solve the no-TA problem if that's a prerequisite? It's not really feasible to produce them for every class. Will it be chatbots?

I have taught such interactive classes/labs by myself. If you have prepared enough, i.e. have a very solidly laid out worksheet of appropriate difficulty, then a single person can handle about 20 people. About 5 students will have no problem and you just need to quickly check on them once or twice. 10 will need quick interventions. 5 will need more support. You can probably do three rounds in that one hour.

I think 18-24 is too young to choose what to study, but not too young to study.

exactly. And it applies generally in life too. esp. in "western" well-off places.

i have met (okay, seen eyes of) ~12y old kids with probably "35y-old"-grade experience behind... And i have met a few 38 or 43y old human exemplars that barely pass for 6-7-10y old at most.

yeah, teaching is hard. You have to learn more than them, about them, in no time, in order to build the (different) bridge to everyone. Takes... time. And gumption.

The thing that breaks my heart is that we have a much better understanding of adult learning. It didn't need to be that painful. That's not the lecturers fault. It takes a while to learn how to teach. It is the fault of our education system which thinks "let's throw seniors into a teaching situation without any grounding or support". We can also, simultaneously, fault the education system for a high school system that does not prepare people for college at all.

Sure glad we spend a lot of money on football coaches, though.

What I've learned is that trying to teach others something will help you better understand what you are teaching. Not only you have to analyze different aspects you never considered, but you have to reply to questions you would never ask. You also have to put things in order before explaining to seome and chances are you will never do it otherwise because you are convinced you know it well enough.

That's true, it's difficult to encourage independent learning at undergrad level and we often end up hand holding and spoon feeding material like in high school. This is partly because it's an easy fix to avoid the most negative student evaluations from the "I won't put in the work and when I fail it's the teacher's fault" types. There aren't many of those but the vocal few can really ruin evaluation average of an otherwise great course. The downside of the policy is obviously that the can gets kicked down the road and employers have to deal with the inability to learn independently.
