I ultimately think that you need to both raise the economic incentives, and lower the disincentives.
Hmm. I'm not sure that this is such a good idea, given that the motivation that one has for teaching seems to be strongly based on social rather than market motives, and introducing market incentives to a situation governed by social incentives has been known to just screw things up.
For example, my best friend has a daughter, and I've been giving her various books and games that either I used to enjoy, or which feel like they might be fun and useful for learning a mathematical mindset. I do this out of a general desire for her to have fun with them, learn useful things, and come to love science. Now if you told me that I'd get a cut out of her future earnings, it seems quite possible that that notion would start dominating my thoughts whenever I thought of giving something to her, and I'd start thinking stuff like "well, I could buy her this board game, but it's kinda expensive and any individual game is unlikely to have a big impact by itself, so would it be a good investment? Probably not." And she'd be worse off as a result.
It seems easy to imagine similar failure modes that would start cropping up once you encouraged teachers to, in effect, start thinking in terms of "how could I profit from this kid" rather than "what would be the best for this kid". For instance, they might focus all of their efforts on the kids who showed the most talent and were already the most likely to succeed. They could even actively try to encourage the low-talent kids to drop out, so that they'd have more time to focus on the more promising ones. Or they could encourage their students towards careers that generally cause people to be unhappy but pay well, or teach the students attitudes towards life that promoted a focus on money above all else. Or, like those Israeli parents who started being more late once a fine was introduced and they could thus pay off their guilt for being late, some of the teachers might start thinking, "well if this kid doesn't do well in life later on, I'm already paying the cost in the form of getting less money from them, so I don't need to feel guilty about giving them a bad education". Et cetera.
Intuitively at least, it would feel like a better idea to raise the social incentives, not the financial ones. Part of the reason why I'm happy to give my friend's daughter stuff is that she's not just any random child who I'll never see again: she's my best friend's kid, which means that I should be hearing about how she's doing for as long as I live. Maybe she'll some day become fantastically successful at something, and then credit part of her success to the role I played in her life. Attempts to replicate this effect could involve making individual teachers responsible for their students for a longer time (so more "you'll have this teacher for the next six years", less "you'll have six different teachers over the next six years"), or even just providing a means for the teachers to stay in some kind of contact with their students even when the teacher's no longer teaching them.
I think this is true, and it's something I have a lot about. What behaviors would this reward system actually incentivize?
I figured there would be two strategies teachers could use to maximize profit. One would involve as you said, focusing on the top students and taking them under your wing, making sure YOU are the one who teaches them as much as possible.
The other would be to instead focus on motivating and effectively teaching as many kids as humanly possible, regardless of their perceived potential, and simply playing the odds.
Other possible strategie...
Problems
Problems have bottlenecks. To solve problems, you need to overcome each bottleneck. If you fail to overcome just one bottleneck, the problem will go unsolved, and your effort will have been fruitless.
In reality, it’s a little bit more complicated than that. Some bottlenecks are tighter than others, and some progress might leak through, but it usually isn’t anything notable.
Education
There is a lot wrong with education. Attempts are being made to improve it, but they’re glossing over important bottlenecks. Consequently, progress is slowly dripping through. I think that it’d be a better use of our time to take the time to think through each bottleneck, and how it can be addressed.
I have a theory of how we can overcome enough bottlenecks such that progress will fall through, instead of drip through.
Consider how we learn. Say that you want to learn parent concept A. To do this, it’ll require you to understand a bunch of other things first
My groundbreaking idea: make sure that students know A1…An before teaching them A.
The bottlenecks to understanding A are A1…An. Some of these bottlenecks are tighter than others, and in reality, there are constraints on our ability to teach, so it’s probably best to focus on the tighter bottlenecks. Regardless, this is the approach we’ll need to take if we want to truly change education.
How would this work?
1) Create a dependency tree.
2) Explain each cell in the tree.
3) Devise a test of understanding for each cell in the tree.
4) Teach accordingly.
Where does our system fail us?
My proposal
I propose that we pool all of our resources and make a perfect educational web app. It would have the dependency trees, have explanations for each cell in each tree, and have a test of understanding for each cell in each tree. It would test the user to establish what it is that he does and doesn’t know, and would proceed with lessons accordingly.
In other words, usage of this web app would be mastery-based: you’d only proceed to a parent concept when you’ve mastered the child concepts.
Motivation
Motivation would be another thing to optimize.
One way to do this would be to teach things to students at the right times. Lack of interest is often due to lack of understanding of child concepts, and thus lack of appreciation for the beauty and significance of a parent concept. By teaching things to students when they’re able to appreciate them, we could increase students’ motivation.
Another way to optimize motivation would be to do a better job of teaching students things that are useful to them (or things that are likely to be useful to them). In todays system, students are often times forced to memorize lots of details that are unlikely to ever be useful to them.
By making teaching more effective, I think motivation will naturally increase as well (it’ll eliminate the lack of motivation that comes with the frustration of bad teaching).
Pooling of resources
The pooling of resources to create this web app is analogous to how resources were pooled for Christopher Nolan to make a really cool movie. When you pool resources, a lot more becomes possible. When you don’t pool resources, the product often sucks. Imagine what would happen if you tried to reproduce Batman at a local high school. This is analogous to what we’re trying to do with education now.
How would this look?
I’m not quite sure. Technically, kids could just sit at home on their computers and work through the lessons that the web app gives them… but I sense that that wouldn’t be such a good idea. It’d probably be best to require kids to go to a “school-like institution”. Kids could work through the lessons by themselves, ask each other for help, work together on projects, compete with each other on projects etc.
Certificates
I envision that credentials would be certificate-based. You’d get smaller certificates that indicate that you have mastered a certain subject. Today, the credentials you get are for passing a grade, or passing a class, or getting a degree. They’re too big and inflexible. For example, maybe the plant unit in intro to biology isn’t necessary for you. Smaller certificates allow for more flexibility.
Deadlines
Deadlines are a tough issue. If they exist, there’s a possibility that you have to cram to meet the deadline, and cramming isn’t optimal for learning. However, if they don’t exist, students probably won’t have the incentive to learn. For this reason, I think that they probably do have to exist.
My first thought is that deadlines should be personalized. For example, if I moved 50 steps and the deadline was at 100 steps, the next deadline should be based on where I am now (step 50), not where the deadline was (step 100).
My second thought is that deadlines should be rather loose, because I think that flexibility and personalization are important, and that deadlines sacrifice those things.
My third thought, is that students should be given credit for going faster. In our one-size-fits-all system now, you can’t get credit for moving faster than your class. I think that if you want to work harder and make faster progress, you should be able to and you should be given credentials for the knowledge that you’ve acquired. Given the chance, I think that many students would do this. I think this would allow students to really thrive and pursue their interests.
Tutoring
I think that it’d be a good idea to require tutoring. Say, in order to get a certificate, after passing the tests, you’d have to tutor for x hours.
Tutoring helps you to master the concept, because having to explain something will expose the holes in your understanding. See The Feynman Technique.
Tutoring allows for social interaction, which is important.
Social Atmosphere
The social atmosphere in these “schools” would also be something to optimize. It's not something that people think too much about, but it has a huge impact on how people develop, and thus on how society develops.
I’m not sure exactly what would be best, but I have a few thoughts:
The idea of social value is horrible. In schools today, you grow up caring way too much about how you look, who you’re friends with, how athletic you are, how smart you are, how much success you have with the opposite sex… how “good” you are. This bleeds into our society, and does a lot to cause unhappiness. It should be avoided, if possible.
Relationships are based largely on repeated, unplanned interactions + an environment that encourages you to let your guard down. I think that schools should actively provide these situations to students, and should allow you to experience these situations with a variety of types of people (right now you only get these repeated, unplanned interactions with the cohort of students you happen to be with, which limits you in a lot of ways).
Rationality
I propose that rationality be a core part of the curriculum (the benefits of making people better at reasoning would trickle down into many aspects of life). I think that this should be done in two ways: the first is by teaching the ideas of rationality, and the second is by using them.
The ideas of rationality can be found right here. Some examples:
After the ideas are taught, they should be practiced. The best way that I could think of to do this is to have kids write and critique essays (writing is just thought on paper, and it’s often easier to argue in writing than it is in verbal conversation). Students could pick a topic that they want to talk about, make claims, and argue for them. And then they could read each others’ essays, and point out what they think are mistakes in each others’ reasoning (this should all be supervised by a teacher, who should probably be more of a benevolent dictator, and who should also contribute points to the discussions).
I think that some competition and social pressure could be useful too; maybe it’d be a good idea to divide students into classes, where the most insightful points are voted upon, and the number of mistakes committed would be tallied and posted.
Writing
Right now, essays in schools are a joke. No one takes them seriously. Students b.s. them, and teachers barely read them, and hardly give any feedback. And they’re also always on english literature, which sends a bad message to kids about what an essay really is. Good writing isn’t taught or practiced, and it should be.
Levels of Action
Certain levels of action have impacts that are orders of magnitude bigger than others. I think that improving education this much would be a high level action, and have many positive effects that’ll trickle down into many aspects of society. I’ll let you speculate on what they are.
