Current education system is broken. You can't learn anything. Learning need feedback loop, but this do not exist. In school, you hand in your homework, get the feedback only after Christmas. Because human cannot evaluate 100 students' homework efficiently. Majority of academic textbook are trash. Some author even say "we have 300 new exercises in this edition" proudly, while the solution is often either nonexistent,…

>In school, you hand in your homework, get the feedback only after Christmas. Is this supposed to be a problem? Research says that delays in getting corrections are not all that important, you still end up learning even if there's a fairly large gap. https://pcl.sitehost.iu.edu/rgoldsto/courses/dunloskyimprovi...

Paper is more focused on "feedback benefit learning" instead of how long should people wait for feedback.

Seems that you are quoting another paper instead. But I don't think it is definitive, as you see, n=27. Also the experiment setting is not about how long after initial test, it is about how short before the next test.

Earlier quoted context omitted.

I'm sorry, but I've taught a lot of students at the university level. Some of them have exactly this attitude. You're simply wrong. And on the long term path to failure. The exercises are invaluable. You don't get the answers because then you look at them. The whole point of the exercises is for you to do them, and then for you to figure out if you are right or wrong! The content of the exercises isn't in the book be…

Yeah reading and doing stuff is how you learn any topic, getting the right solution is not really the point (and arguably should not be in the book in the first place). The main issue with education is grades and how obsessed people are with those as a sorting mechanism for students.

OK well then 2+2 is 5. I figured out the answer myself, good for me, good for the humanity.

This is gross posturing and indicates future rent seeking behaviour. Imagine getting in front of people and telling them that some corporation trained the font of wisdom, and that you'd be happy to charge fuckin' admission! What absolute dogshit. All that future rent seeking for a glorified DAN prompt. This is the digital equivalent to making everyone do bullshit jobs because we never figured out how to deal with increased worker productivity from manufacturing.

One of the biggest factors impacting education outcomes is students per teacher. Students tutored one-on-one learn better than students in small classes, and students in small classes learn better than students in large classes. Because if there are fewer students per teacher, the teacher can devote more time and attention to each student. AI promises to put a decent one-on-one tutor in the hands of every student for…

Jesus, no! Not all of my teachers were great, and most of the knowledge I got, I earned on my own. But they were part of a world that had nothing to do with the world of my parents--my teachers were learned , where my immediate family was not. My teachers were, if nothing else, an example to follow, a light, a guide. >> No longer will private tutors be restricted to the rich only. It's not as simple. I've met plenty…

> Jesus, no! Not all of my teachers were great,

this!

AI isn't as good as a great teacher but its better than a bad teacher and there aren't enough good teachers to go around.
