"To increase profits" is the obvious answer to the title. Otherwise very mundane, common sense updates. Just an engagement farming article.

  Khan Academy is a 501(c)3 [0] non-profit. "Increase revenue" maybe, or alternatively they may actually believe in their mission. Depends on how cynical you're feeling today I guess.

  - ActionHank 2y ago
    Non profit doesn't mean what people think it means. Those expenses could be anything and anyone. They could be increasing rev to further increase expenses like salaries and exec pay. Not "shareholders" in a typical corporate business way, but still driving profits for a handful of key stakeholders. Not a bad thing, just don't think non-profit = altruistic orphan saving factory.
    - lolinder 2y ago
      I accounted for that by conceding that "increase revenue" would be the cynical explanation. "Increase profit" would strictly speaking be illegal. Regardless, the idea that Sal Khan specifically isn't fundamentally serious about education and sees this as his personal golden goose is a special kind of cynicism.
    - seanhunter 2y ago
      Understand and agree with your general point, but Sal Khan quit a job at a hedge fund to be a maths tutor and that's how khan academy got started. I genuinely don't think money is his primary motivation. If it was, he would have just stayed at the hedge fund.

      A section 501(c)(3) organization must not be organized or operated for the benefit of private interests, such as the creator or the creator's family, shareholders of the organization, other designated individuals, or persons controlled directly or indirectly by such private interests. No part of the net earnings of a section 501(c)(3) organization may inure to the benefit of any private shareholder or individual. A private shareholder or individual is a person having a personal and private interest in the activities of the organization. https://www.irs.gov/charities-non-profits/charitable-organizations/inurement-private-benefit-charitable-organizations https://www.irs.gov/charities-non-profits/charitable-organiz... None of that means that employees of 501(c)(3) organizations can't earn competitive compensation. But I think they'd be on pretty slippery ground if any part of compensation was tied directly to revenue increases.

      IKEA is a complicated mess of nonprofits and for profits. Khan Academy is just a 501(c)3.

  No. Everyone is better off the more path people know. One of the huge struggles in the west currently is the cancer of risk aversion. People can’t grok statistics, so we spend huge efforts negating 10^-6 risks.

  The non-profit famous for giving away all of its educational material, in multiple languages, with the goal of allowing no-cost world class education to anyone, is trying to juice it's profits?

The fun thing about getting math help from the ai is that okay, sure it can explain how fractions work to a third grader, but it can also explain how fiber bundles work to a graduate student. Maybe it gets the details wrong, but like even if it's wrong sometimes, it's far better than googling or wikipedia or even a text book sometimes, because you can interrogate it interactively and ask for clarifications. Yes, a tutor or a teacher is going to be better, but not everyone has access to a math expert.
- skydhash 2y ago
  > Maybe it gets the details wrong, but like even if it's wrong sometimes, it's far better than googling or wikipedia or even a text book sometimes Are people consulting only one book/source on any given subject? I remember learning Python and C, and it was such a mixture of books/articles/forums/wiki, I can't even remember the process. I do remember understanding pointers easily because of a chapter of another book about memory models in OS. Learning is an iterative process and the expert is just there to shorten the way, not to carry you through it.
- ndriscoll 2y ago
  I've found that at least chatgpt still produces complete nonsense with graduate level material (category theory). It's slightly better than the mLab[0] as a reference. When you try to guide it back onto something meaningful, it just ignores what you told it. In fact, I had a similar experience with programming where I asked it to explain a diff, and when it got it wrong and I told it so, it still just kept repeating the wrong information. Maybe the paid version is better, but the public demo seems like a useless toy to me. I've found Wikipedia to be an excellent resource for math/physics once you're ~halfway through a math degree to have a good baseline level of knowledge to understand it. The trouble with math is one of the important goals is to teach people not to produce nonsense and to be able to tell the difference between and argument that sounds good vs. an argument that's sound and good. A nonsense generator (presented as authoritative) is perhaps not the best way to do that. Obviously its abilities could change in the span of a couple years, so it's probably still worthwhile to explore how we would use it if it were useful.

Because it's cheaper than paying people.

  From my understanding, they are trying to make Math education available to the entire population of the world. And now provide one on one personalized tutoring that currently only a fraction of the wealthiest people in their respective countries can afford. It’s fortunate that it is cheaper than paying people.

  Your comment is extremely shortsighted given the history of Khan Academy and the goals of that organization. I'm pretty sure that if they could pay for a tutor for every kid on the planet, they would. AI is being used to democratize access to education for underserved populations, and we should laud that effort despite some of the drawbacks of AI.
- commandlinefan 2y ago
  Not that much. Both of my kids worked as in-person math tutors through high school for extra spending money. They made $10/hour, and that's close to the top-end of what math tutors actually get. Math teaching ability isn't valuable enough to command much in the way of compensation... even though we keep hearing that it's important.

  I am reminded of a grad school friend with a rich extended family, who was bent on persuading me that the super high quality luggage he acquired was more than worth the price. What I would have had to give up to get that luggage, if that was even possible, or where I was supposed to store it in my tiny apartment, were not concerns that computed for them.
- jyunwai 2y ago
  Recent research in education has actually explored the question. The Center for American Progress published a summary of research findings [1] in January that noted: "High-dosage tutoring is one of the few school-based interventions with demonstrated significant positive effects on both math and reading achievement," so it's a viable solution—if there's funding. The limitation is price. Many listings for reputable math tutors are greater than $60 USD per hour. If you go by the CAP's minimum for "high-dosage tutoring" of a 30-minute session three times a week, that sums to at least $360 USD per month. Many parents do pay for this for children, but it's an unaffordable expense for many people. There is an initiative to provide free tutoring (via the "Schoolhouse" project founded by Khan Academy's Sal Khan to have volunteer tutors, who are often university students), but it's not yet clear to me whether the quality of volunteer tutors will be sufficient to make a difference in the success of students. I've also read elsewhere that one of the most important factors in tutoring effectiveness is the frequency of consistently meeting with the tutor. An AI tutor would help with frequency via lowering the price—though then again, there may be more feelings of accountability with meeting a human person at a scheduled time, versus using a software tool consistently.

Great! I failed in university at math. Why? Because the tutors had not the time to help me. My level of math was not the same as the other students as i was not in the math part of a gymnasium. I struggled and wasted a lot of time and energy to even find good explanations. And when i had a math group, one girl was super nice but knew so muchmore than i did because of her math in gym. Professors asumed so much knowledge and no one cared to try to help people. Best help were people from india on youtube with bad english. And the most ridiculous part: Every year around the globe people teach this level of university math to probably millions of students. We should have the perfect free educational platform which teaches everyone perfectly already because so many tutors and professors lecture on the same topics over and over and over again. Our educational system is a joke.

  THEN SAID A teacher, Speak to us of Teaching. And he said: No man can reveal to you aught but that which already lies half asleep in the dawning of your knowledge. The teacher who walks in the shadow of the temple, among his followers, gives not of his wisdom but rather of his faith and his lovingness. If he is indeed wise he does not bid you enter the house of his wisdom, but rather leads you to the threshold of your own mind. The astronomer may speak to you of his understanding of space, but he cannot give you his understanding. The musician may sing to you of the rhythm which is in all space, but he cannot give you the ear which arrests the rhythm nor the voice that echoes it. And he who is versed in the science of numbers can tell of the regions of weight and measure, but he cannot conduct you thither. For the vision of one man lends not its wings to another man. And even as each one of you stands alone in God’s knowledge, so must each one of you be alone in his knowledge of God and in his understanding of the earth. The Prophet by Khalil Gibran
  - Viliam1234 2y ago
    > No man can reveal to you aught but that which already lies half asleep in the dawning of your knowledge. That's called "zone of proximal development" in pedagogy. However, "that which already lies half asleep in the dawning of your knowledge" is often a consequence of things that were revealed to you previously. When you learn, you could probably make any specific step alone, but you cannot make all the steps alone.
LightFog 2y ago
Maybe I’m reading too much into it but the roadmap mentioning switching from GPT4 Turbo to 4-o and hoping for better math performance feels like they are betting on a significant near term reliability improvement in LLMs without any other real plans. That magic jump is starting to look more and more doubtful by the day.

  Also pretty important that they're using a calculator for numerical problems. That should avoid some of the most embarrassing mistakes.
raytopia 2y ago
I can't find a link right now but Salman Khan (the founder of Khan Academy) is a believer that the future of education is 1 teacher for 1 student so it makes sense why they'd be investing so heavily in AI tutors.
- empath75 2y ago
  Yeah I think a class where a teacher is facilitating one-on-one AI instruction with a room full of students seems both dystopian and inevitable. I do worry about parasocial relationships the kids are going to form with these tutors though. A lot of these kids don't have great situations at home and if you have an endlessly patient AI that doesn't stick to the script, you could run into trouble.

The irony is that the world where AI could reasonably explain and teach any level of math is the same world where most of such graduates would be unemployed anyways. You’re already seeing oversupply of educated folks in India and China. Graduate students working as baristas in USA, etc. Sadly inevitable. In any case it’s good to have the resources I suppose. I’m also fundamentally skeptical of these stats around math struggling. What percentage of kids who would be very likely to use Khan Academy are struggling with math? And what percentage who are not would even use khan academy to begin with? Most of the problems with students doing poorly are sadly societal - not to say that this isn’t useful, though.
- trod123 2y ago
  AI won't ever be able to teach math because AI cannot reason. It handles information very differently than humans do. It is at best a flawed oracle that may lie through omission without you being able to tell. This is supported by the fact that there are hard limits to computation, in terms of both Computability Theory, and Complexity Theory that are often disregarded by the novice and magical thinker alike despite being largely solved fields by experts in Computer Science, at least in terms of Computability Theory. Most of this work was completed in the 1950s. This is not a difficult a subject, but most people online simply are unwilling to do the work to rationally learn this and instead choose to try and hide their own ignorance because they feel inadequate, or perhaps they are engaging in something more malevolent. The reasoning (false justification) doesn't really matter. It is, however; quite telling when expert's have validated these things, and yet any mention contrary to a narrative provokes downvotes in a public forum to remove it from view. A perfect example of intentional actions done by third-parties trying to misinform others about the risks (by those parties actions removing legitimate and valid information). For those with the cajones to actually learn this stuff. Here is a link. It seems very jaron laden but it provides a true understanding of how computers actually work which is sorely lacking in the youth of today. MIT 18.404J Theory of Computation https://www.youtube.com/watch?v=9syvZr-9xwk&list=PLUl4u3cNGP60_JNv2MmK3wkOt9syvfQWY https://www.youtube.com/watch?v=9syvZr-9xwk&list=PLUl4u3cNGP... The only net benefit AI has towards society is towards destructive ends because there are far more destructive people whose efforts scale more in general when compared to the good people today. These people often do things which cannot be undone (salting the earth and burning the bridge). Simply not having a sufficient background, or failing to perform basic due dilligence often will place most people in that destructive cohort regardless of their own personal beliefs. Outcomes matter more than intentions, and the devil is always in the details. A perfect example of this potential landmine of a field would be anything dealing with the underlying mechanisms involved in human to human communication. There is an uncanny valley, and distorted reflected appraisal will occur inevitably in any human to AI interface seeking to mimic human communication. Case studies from torture during the Korean Conflict (1950s) show that distorting reflected appraisal leads to either psychotic or dissociative behavior that progresses as exposure increases, it can permanently break people to the point where they cannot recover. Often, the first thing to go is rational thought. Multiple experts cover this and confirm the findings (Lifton, Meerloo). So what do you suppose will happen when AI distorts reflected appraisal (because it can't be tested sufficiently to the contrary) and its then used on the next generation of children? (who are inherently vulnerable to permanent change at that stage of development). If as a result, they end up either killing themselves or others, or become people incapable of rational thought (which impulse control is correlated with), do you think they'll be alive or survive very long? What indicators would there be that this is happening (none, other than increasing chaotic violence) Who do you think will be responsible for crippling them if that were to come to pass? Would any kind of justification ever be able to justify that outcome? Could we even recover from intentional crazy-making as a society? (likely not, insanity cannot be cured). These things are not toys. Outcomes matter.

Sounds like most of what they're doing is related to prompting, chain-of-thought reasoning and similar, on top of a 'vanilla' foundation model. Sounds like something an ambitious student could replicate / improve upon, so given their mission, it'd be cool if they published the exact techniques they're using and their benchmark results.

Given its 4$ per month[1] and they are a non-profit with just 55M$ revenue. How is GPU cost and hence their with OpenAI for this going to work if it becomes really-good and 100's of millions of kids start using it? Renting a 24GB VRAM Runpod is ~0.5$ per hour.

- dghlsakjg 2y ago
  The math seems about right to me. Using a chatbot for an hour might only use a minute or two of computer time, I would be genuinely surprised if a human could hit ten minutes of compute time/hour of interaction. Most responses in my technical chats are under 5 seconds, so using a full hour of GPU time is going to take A LOT of questions. I heavily use ChatGPT via a desktop client and my own key, and I am at $3.90 for the month after making a mistake where I accidentally was sending a 30k token prompt repeatedly, that cost me about $2. Using an optimized approach, it is VERY hard to incur a $4/month bill. I imagine that Khan academy has a much better bulk-pricing agreement with openAI, and that they can probably have a caching layer that can look for previously asked questions.

If you want good math teachers, you have to make attractive offers that will draw in the best talent. So, let's do some math: The median price of an existing single-family home in the Califoria Bay Area in February 2024 was $1.25 million. The range of teacher salaries in the Bay Area is $50K - $100K. A reasonable downpayment on that home would be ~$250,000, followed by yearly payments in the range $64K (30-year) to 80K (15-year). Following the 'housing should consume 30% of income' - allowing teachers to have children and buy a car and go on vacations and so on - this would require salaries of $200K - $250K per year under current market conditions. Thus, anyone wanting their own home and a family will probably not be considering a career in teaching - you'd end up as a lifelong two-room apartment renter. AI tutoring is a great idea - but a tutor isn't a teacher. The job of the teacher is to excite and motivate the students, provide overall guidance and appropriately difficult problem sets for the students to work on. The one-one-one tutor is there to help with the problem sets, especially when students get stuck. Unfortunately, here in the USA we have a system that values the CEO of McDonalds - which delivers very unhealthy food to the population - at $19 million per year - and teachers are valued at the same rate as garbage truck operators (at least in the Bay Area). The result is that most students entering higher education need one-two years of remedial math education before being able to grasp the higher math, e.g. vector calculus, linear algebra, complex analysis etc., which is needed for modern engineering and scientific disciplines. This results in competitive disadvantage relative to China and other countries that invest heavily in childhood education.

  I am in agreement with a great deal of what you say, except that one thing is missing. Five years ago it was not possible to look at what systems were around and suppose that AI could be the tutor. I see posts arguing that this is not a good tutor, fair enough, but at least some reasonable and capable people think it is. Following that trend line, it seems quite possible to me that in five years AI will be the teacher. (Of course it may replace CEOs also.)

One issue that traditional AI Agent reasoning built on Theory of Mind(ToM) (ToM: I know what you are thinking, so I can predict what you will do next.) was hard to get right was because the domain model and interface was quite tough to design. Agents did not fully understand and model the belief state of the person. But more importantly, there was possibly also no way to quickly _generate_ lots of plans and test them in a Domain independent manner (RHLF is horribly inefficient for this). Now there are AI agents are great at generating plans (examples of what could work) that can be tested with kids and creators and provide feedback to tune not just LLMs but also add to the Domain models. This can solve a lot of interesting problems that have plagued tutoring systems: 1. Improve sample efficiency of generated plans to get to the right goal while meeting all the subgoals for a plan. 2. Enrich engineered and correct neuro-symbolic models of reasoning with better knowledge representations. 3. Quantitative psychometric systems that use metrics like proficiency could only be as good as the underlying “factor” model and hypothesis, but one could test multiple more interesting hypothesis more quickly: "Are you mentally tiered?", "Here is a hint: ___. Does that help?".
light_hue_1 2y ago
I've taught math at every level. From volunteering to teach it to grade school kids, to getting paid for highschool tutoring, and at the university level both for undergrads and now with my own grad students. I tried Khanmigo. It is counterproductive junk. It simply doesn't understand what a student knows and it has to idea how to give examples or provide perspective shifts that help students. That's what a good tutor does. It gets stuck explaining the same things in the same ways but with different words over and over again. It has no idea how to think geometrically vs algebraically and how to switch between the two. And it can't carry out even simple proofs.
- beauzero 2y ago
  More people can afford phones than can afford tutors (or even books). We shouldn't get rid of tutors anymore than we should throw out Khanmigo because it isn't perfect.

Conversational dialogue seems like a fascinating distraction. Many people who have (unsuccessfully) attempted to apply AI to education have focused too much on the "explanation" part and not enough on scaffolding, navigating, and managing the entire learning process. It’s easy to go on a wild goose chase building an explanation AI. You fall in love with the idea of AI having conversational dialogue with students, and then you get lost in the weeds of complexity. You solve just enough of the problem to produce a cool demo, yet you're still hopelessly far away from self-service learning in real life. I don't think conversational dialogue is even necessary. What we do at mathacademy.com is hard-code explanations and break them up into bite-size pieces that are served at just the right moment. And we close the feedback loop by having students solve problems, which they need to do anyway. (The student's "response" is whether they got the problem correct.) Sure, hard-coding explanations feels tedious, takes a lot of work, and isn't "sexy" like an AI that generates responses from scratch – but at least it's not a pipe dream. It's a practical solution that lets us move on to other components of the AI that are just as important. What are those other components? A handful off the top of my head: * After a minimum effective dose of explanation, the AI needs to switch over to active problem-solving. Students should begin with simple cases and then climb up the ladder of difficulty, covering all cases that they could reasonably be expected to solve on a future assessment. * Assessments should be frequent and broad in coverage, and students should be assigned personalized remedial reviews based on what they answered incorrectly. * Students should progress through the curriculum in a personalized mastery-based manner, only being presented with new topics when they have (as individuals, not just as a group) demonstrated mastery of the prerequisite material. * After a student has learned a topic, they should periodically review it using spaced repetition, a systematic way of reviewing previously-learned material to retain it indefinitely into the future. * If a student ever struggles, the system should not lower the bar for success on the learning task (e.g., by giving away hints). Rather, it should strengthen a student’s area of weakness so that they can clear the bar fully and independently on their next attempt.

If AI is good enough to teach math, why not have the AI 'do the math' instead? At a certain point, wouldn't we have to ask whether it makes any economic sense to teach math to the masses? If AI is good enough to teach people to drive, then it should be good enough to drive the car itself. At that point, it would be pointless to teach the masses to drive when the AI can do it for them. If AI is good enough to cook, ... So on and so forth. The intention is noble but where does it all lead?

Being able to read, write, do math and think and do things for myself is very improtant to me - it's even more imprtant to me that I live in a vibrant society full of people who can do likewise. I don't want to live on the Axiom in Wall-e.

  It's disappointing. A year is enough time for them to have collected some real data on whether this has made kids worse or better at math or moved the needle at all. If they don't have this data yet, why are they blasting into the second year, and also promoting that we use the system in other subjects too? I'm hoping they have some data and just haven't published it yet, which is plausible given how slow the process is...

Seems disrespectful of students to write two blog posts about this without clarifying if you foist OpenAI’s explicitly anticompetitive legal terms on students. If the OpenAI data use policy applies to Khan Academy students, they implicitly require every student user of this to not use the output to compete with OpenAI (taken literally, you can’t use what your tutor says to you for anything, since it’s always going to compete with OpenAI) Imagine how dumb it is to say “our thing can do everything. You can use it, but you can’t use it to do anything that competes with us.” Let that sink in. Can you name one thing you can do using the output of a thing that does everything which doesn’t compete with the everything thing? What a shame to flush Khan academy just to hop aboard the hype train. I know I’ll probably get downvoted for being negative but to write so much without clarifying what the “Open” AI legal terms mean for students is actively harmful to student trust. If anyone needs a reason to pity OpenAI, just remember how they betray their true name. That is a profound failure and I would not wish it on anyone.

  Non profit doesn't mean what people think it means. Those expenses could be anything and anyone. They could be increasing rev to further increase expenses like salaries and exec pay. Not "shareholders" in a typical corporate business way, but still driving profits for a handful of key stakeholders. Not a bad thing, just don't think non-profit = altruistic orphan saving factory.
  - lolinder 2y ago
    I accounted for that by conceding that "increase revenue" would be the cynical explanation. "Increase profit" would strictly speaking be illegal. Regardless, the idea that Sal Khan specifically isn't fundamentally serious about education and sees this as his personal golden goose is a special kind of cynicism.
  - seanhunter 2y ago
    Understand and agree with your general point, but Sal Khan quit a job at a hedge fund to be a maths tutor and that's how khan academy got started. I genuinely don't think money is his primary motivation. If it was, he would have just stayed at the hedge fund.

The fun thing about getting math help from the ai is that okay, sure it can explain how fractions work to a third grader, but it can also explain how fiber bundles work to a graduate student. Maybe it gets the details wrong, but like even if it's wrong sometimes, it's far better than googling or wikipedia or even a text book sometimes, because you can interrogate it interactively and ask for clarifications. Yes, a tutor or a teacher is going to be better, but not everyone has access to a math expert.

skydhash 2y ago
> Maybe it gets the details wrong, but like even if it's wrong sometimes, it's far better than googling or wikipedia or even a text book sometimes Are people consulting only one book/source on any given subject? I remember learning Python and C, and it was such a mixture of books/articles/forums/wiki, I can't even remember the process. I do remember understanding pointers easily because of a chapter of another book about memory models in OS. Learning is an iterative process and the expert is just there to shorten the way, not to carry you through it.
ndriscoll 2y ago
I've found that at least chatgpt still produces complete nonsense with graduate level material (category theory). It's slightly better than the mLab[0] as a reference. When you try to guide it back onto something meaningful, it just ignores what you told it. In fact, I had a similar experience with programming where I asked it to explain a diff, and when it got it wrong and I told it so, it still just kept repeating the wrong information. Maybe the paid version is better, but the public demo seems like a useless toy to me. I've found Wikipedia to be an excellent resource for math/physics once you're ~halfway through a math degree to have a good baseline level of knowledge to understand it. The trouble with math is one of the important goals is to teach people not to produce nonsense and to be able to tell the difference between and argument that sounds good vs. an argument that's sound and good. A nonsense generator (presented as authoritative) is perhaps not the best way to do that. Obviously its abilities could change in the span of a couple years, so it's probably still worthwhile to explore how we would use it if it were useful.

Your comment is extremely shortsighted given the history of Khan Academy and the goals of that organization.

Not that much. Both of my kids worked as in-person math tutors through high school for extra spending money. They made $10/hour, and that's close to the top-end of what math tutors actually get. Math teaching ability isn't valuable enough to command much in the way of compensation... even though we keep hearing that it's important.

jyunwai 2y ago
Recent research in education has actually explored the question. The Center for American Progress published a summary of research findings [1] in January that noted: "High-dosage tutoring is one of the few school-based interventions with demonstrated significant positive effects on both math and reading achievement," so it's a viable solution—if there's funding. The limitation is price. Many listings for reputable math tutors are greater than $60 USD per hour. If you go by the CAP's minimum for "high-dosage tutoring" of a 30-minute session three times a week, that sums to at least $360 USD per month. Many parents do pay for this for children, but it's an unaffordable expense for many people. There is an initiative to provide free tutoring (via the "Schoolhouse" project founded by Khan Academy's Sal Khan to have volunteer tutors, who are often university students), but it's not yet clear to me whether the quality of volunteer tutors will be sufficient to make a difference in the success of students. I've also read elsewhere that one of the most important factors in tutoring effectiveness is the frequency of consistently meeting with the tutor. An AI tutor would help with frequency via lowering the price—though then again, there may be more feelings of accountability with meeting a human person at a scheduled time, versus using a software tool consistently.

Great! I failed in university at math. Why? Because the tutors had not the time to help me. My level of math was not the same as the other students as i was not in the math part of a gymnasium. I struggled and wasted a lot of time and energy to even find good explanations. And when i had a math group, one girl was super nice but knew so muchmore than i did because of her math in gym. Professors asumed so much knowledge and no one cared to try to help people. Best help were people from india on youtube with bad english. And the most ridiculous part: Every year around the globe people teach this level of university math to probably millions of students. We should have the perfect free educational platform which teaches everyone perfectly already because so many tutors and professors lecture on the same topics over and over and over again. Our educational system is a joke.

THEN SAID A teacher, Speak to us of Teaching. And he said: No man can reveal to you aught but that which already lies half asleep in the dawning of your knowledge. The teacher who walks in the shadow of the temple, among his followers, gives not of his wisdom but rather of his faith and his lovingness. If he is indeed wise he does not bid you enter the house of his wisdom, but rather leads you to the threshold of your own mind. The astronomer may speak to you of his understanding of space, but he cannot give you his understanding. The musician may sing to you of the rhythm which is in all space, but he cannot give you the ear which arrests the rhythm nor the voice that echoes it. And he who is versed in the science of numbers can tell of the regions of weight and measure, but he cannot conduct you thither. For the vision of one man lends not its wings to another man. And even as each one of you stands alone in God’s knowledge, so must each one of you be alone in his knowledge of God and in his understanding of the earth. The Prophet by Khalil Gibran

  > No man can reveal to you aught but that which already lies half asleep in the dawning of your knowledge. That's called "zone of proximal development" in pedagogy. However, "that which already lies half asleep in the dawning of your knowledge" is often a consequence of things that were revealed to you previously. When you learn, you could probably make any specific step alone, but you cannot make all the steps alone.

Maybe I’m reading too much into it but the roadmap mentioning switching from GPT4 Turbo to 4-o and hoping for better math performance feels like they are betting on a significant near term reliability improvement in LLMs without any other real plans.

The irony is that the world where AI could reasonably explain and teach any level of math is the same world where most of such graduates would be unemployed anyways. You’re already seeing oversupply of educated folks in India and China. Graduate students working as baristas in USA, etc. Sadly inevitable. In any case it’s good to have the resources I suppose. I’m also fundamentally skeptical of these stats around math struggling. What percentage of kids who would be very likely to use Khan Academy are struggling with math? And what percentage who are not would even use khan academy to begin with? Most of the problems with students doing poorly are sadly societal - not to say that this isn’t useful, though.

trod123 2y ago
AI won't ever be able to teach math because AI cannot reason. It handles information very differently than humans do. It is at best a flawed oracle that may lie through omission without you being able to tell. This is supported by the fact that there are hard limits to computation, in terms of both Computability Theory, and Complexity Theory that are often disregarded by the novice and magical thinker alike despite being largely solved fields by experts in Computer Science, at least in terms of Computability Theory. Most of this work was completed in the 1950s. This is not a difficult a subject, but most people online simply are unwilling to do the work to rationally learn this and instead choose to try and hide their own ignorance because they feel inadequate, or perhaps they are engaging in something more malevolent. The reasoning (false justification) doesn't really matter. It is, however; quite telling when expert's have validated these things, and yet any mention contrary to a narrative provokes downvotes in a public forum to remove it from view. A perfect example of intentional actions done by third-parties trying to misinform others about the risks (by those parties actions removing legitimate and valid information). For those with the cajones to actually learn this stuff. Here is a link. It seems very jaron laden but it provides a true understanding of how computers actually work which is sorely lacking in the youth of today. MIT 18.404J Theory of Computation https://www.youtube.com/watch?v=9syvZr-9xwk&list=PLUl4u3cNGP60_JNv2MmK3wkOt9syvfQWY https://www.youtube.com/watch?v=9syvZr-9xwk&list=PLUl4u3cNGP... The only net benefit AI has towards society is towards destructive ends because there are far more destructive people whose efforts scale more in general when compared to the good people today. These people often do things which cannot be undone (salting the earth and burning the bridge). Simply not having a sufficient background, or failing to perform basic due dilligence often will place most people in that destructive cohort regardless of their own personal beliefs. Outcomes matter more than intentions, and the devil is always in the details. A perfect example of this potential landmine of a field would be anything dealing with the underlying mechanisms involved in human to human communication. There is an uncanny valley, and distorted reflected appraisal will occur inevitably in any human to AI interface seeking to mimic human communication. Case studies from torture during the Korean Conflict (1950s) show that distorting reflected appraisal leads to either psychotic or dissociative behavior that progresses as exposure increases, it can permanently break people to the point where they cannot recover. Often, the first thing to go is rational thought. Multiple experts cover this and confirm the findings (Lifton, Meerloo). So what do you suppose will happen when AI distorts reflected appraisal (because it can't be tested sufficiently to the contrary) and its then used on the next generation of children? (who are inherently vulnerable to permanent change at that stage of development). If as a result, they end up either killing themselves or others, or become people incapable of rational thought (which impulse control is correlated with), do you think they'll be alive or survive very long? What indicators would there be that this is happening (none, other than increasing chaotic violence) Who do you think will be responsible for crippling them if that were to come to pass? Would any kind of justification ever be able to justify that outcome? Could we even recover from intentional crazy-making as a society? (likely not, insanity cannot be cured). These things are not toys. Outcomes matter.

The math seems about right to me. Using a chatbot for an hour might only use a minute or two of computer time, I would be genuinely surprised if a human could hit ten minutes of compute time/hour of interaction. Most responses in my technical chats are under 5 seconds, so using a full hour of GPU time is going to take A LOT of questions. I heavily use ChatGPT via a desktop client and my own key, and I am at $3.90 for the month after making a mistake where I accidentally was sending a 30k token prompt repeatedly, that cost me about $2. Using an optimized approach, it is VERY hard to incur a $4/month bill. I imagine that Khan academy has a much better bulk-pricing agreement with openAI, and that they can probably have a caching layer that can look for previously asked questions.

If you want good math teachers, you have to make attractive offers that will draw in the best talent. So, let's do some math: The median price of an existing single-family home in the Califoria Bay Area in February 2024 was $1.25 million. The range of teacher salaries in the Bay Area is $50K - $100K. A reasonable downpayment on that home would be ~$250,000, followed by yearly payments in the range $64K (30-year) to 80K (15-year). Following the 'housing should consume 30% of income' - allowing teachers to have children and buy a car and go on vacations and so on - this would require salaries of $200K - $250K per year under current market conditions. Thus, anyone wanting their own home and a family will probably not be considering a career in teaching - you'd end up as a lifelong two-room apartment renter. AI tutoring is a great idea - but a tutor isn't a teacher. The job of the teacher is to excite and motivate the students, provide overall guidance and appropriately difficult problem sets for the students to work on. The one-one-one tutor is there to help with the problem sets, especially when students get stuck. Unfortunately, here in the USA we have a system that values the CEO of McDonalds - which delivers very unhealthy food to the population - at $19 million per year - and teachers are valued at the same rate as garbage truck operators (at least in the Bay Area). The result is that most students entering higher education need one-two years of remedial math education before being able to grasp the higher math, e.g. vector calculus, linear algebra, complex analysis etc., which is needed for modern engineering and scientific disciplines. This results in competitive disadvantage relative to China and other countries that invest heavily in childhood education.

I am in agreement with a great deal of what you say, except that one thing is missing. Five years ago it was not possible to look at what systems were around and suppose that AI could be the tutor. I see posts arguing that this is not a good tutor, fair enough, but at least some reasonable and capable people think it is. Following that trend line, it seems quite possible to me that in five years AI will be the teacher. (Of course it may replace CEOs also.)

One issue that traditional AI Agent reasoning built on Theory of Mind(ToM) (ToM: I know what you are thinking, so I can predict what you will do next.) was hard to get right was because the domain model and interface was quite tough to design. Agents did not fully understand and model the belief state of the person. But more importantly, there was possibly also no way to quickly _generate_ lots of plans and test them in a Domain independent manner (RHLF is horribly inefficient for this). Now there are AI agents are great at generating plans (examples of what could work) that can be tested with kids and creators and provide feedback to tune not just LLMs but also add to the Domain models. This can solve a lot of interesting problems that have plagued tutoring systems: 1. Improve sample efficiency of generated plans to get to the right goal while meeting all the subgoals for a plan. 2. Enrich engineered and correct neuro-symbolic models of reasoning with better knowledge representations. 3. Quantitative psychometric systems that use metrics like proficiency could only be as good as the underlying “factor” model and hypothesis, but one could test multiple more interesting hypothesis more quickly: "Are you mentally tiered?", "Here is a hint: ___. Does that help?".

light_hue_1 2y ago

I've taught math at every level. From volunteering to teach it to grade school kids, to getting paid for highschool tutoring, and at the university level both for undergrads and now with my own grad students. I tried Khanmigo. It is counterproductive junk. It simply doesn't understand what a student knows and it has to idea how to give examples or provide perspective shifts that help students. That's what a good tutor does. It gets stuck explaining the same things in the same ways but with different words over and over again. It has no idea how to think geometrically vs algebraically and how to switch between the two. And it can't carry out even simple proofs.

Conversational dialogue seems like a fascinating distraction. Many people who have (unsuccessfully) attempted to apply AI to education have focused too much on the "explanation" part and not enough on scaffolding, navigating, and managing the entire learning process. It’s easy to go on a wild goose chase building an explanation AI. You fall in love with the idea of AI having conversational dialogue with students, and then you get lost in the weeds of complexity. You solve just enough of the problem to produce a cool demo, yet you're still hopelessly far away from self-service learning in real life. I don't think conversational dialogue is even necessary. What we do at mathacademy.com is hard-code explanations and break them up into bite-size pieces that are served at just the right moment. And we close the feedback loop by having students solve problems, which they need to do anyway. (The student's "response" is whether they got the problem correct.) Sure, hard-coding explanations feels tedious, takes a lot of work, and isn't "sexy" like an AI that generates responses from scratch – but at least it's not a pipe dream. It's a practical solution that lets us move on to other components of the AI that are just as important. What are those other components? A handful off the top of my head: * After a minimum effective dose of explanation, the AI needs to switch over to active problem-solving. Students should begin with simple cases and then climb up the ladder of difficulty, covering all cases that they could reasonably be expected to solve on a future assessment. * Assessments should be frequent and broad in coverage, and students should be assigned personalized remedial reviews based on what they answered incorrectly. * Students should progress through the curriculum in a personalized mastery-based manner, only being presented with new topics when they have (as individuals, not just as a group) demonstrated mastery of the prerequisite material. * After a student has learned a topic, they should periodically review it using spaced repetition, a systematic way of reviewing previously-learned material to retain it indefinitely into the future. * If a student ever struggles, the system should not lower the bar for success on the learning task (e.g., by giving away hints). Rather, it should strengthen a student’s area of weakness so that they can clear the bar fully and independently on their next attempt.

Should mention that I recently wrote an essay that elaborates on this argument with plenty more detail: https://www.justinmath.com/the-situation-with-ai-in-education/ https://www.justinmath.com/the-situation-with-ai-in-educatio...

If AI is good enough to teach math, why not have the AI 'do the math' instead? At a certain point, wouldn't we have to ask whether it makes any economic sense to teach math to the masses? If AI is good enough to teach people to drive, then it should be good enough to drive the car itself. At that point, it would be pointless to teach the masses to drive when the AI can do it for them. If AI is good enough to cook, ... So on and so forth. The intention is noble but where does it all lead?

Are you arguing that people should not learn for themselves how to engage with the patterns in their own world? (math) Are you arguing that people should not be able to take the initiative to move themselves from one place to another of their own volition? (driving)

If you don't, it leads to the general population completely infantilized and beholden to the few large capitalist corporations that run the "AI" that actually do everything. Being able to read, write, do math and think and do things for myself is very improtant to me - it's even more imprtant to me that I live in a vibrant society full of people who can do likewise. I don't want to live on the Axiom in Wall-e.

Calculators are better at addition than us but we still teach children to add.

  Next up: teaching children to question whether or not they should be adding with the same numbers they use to count...

> In fourth grade, only 36% of students are proficient in math. By eighth grade, that number drops to 26%. Followed by: > As we come to the end of our first full pilot school year, Did they not monitor students' performance? Do they not have concrete numbers like the ones quoted in the first paragraph? What better way to demonstrate effectiveness than to evaluate students and see how much improvement they made?

It's disappointing. A year is enough time for them to have collected some real data on whether this has made kids worse or better at math or moved the needle at all. If they don't have this data yet, why are they blasting into the second year, and also promoting that we use the system in other subjects too? I'm hoping they have some data and just haven't published it yet, which is plausible given how slow the process is...

Seems disrespectful of students to write two blog posts about this without clarifying if you foist OpenAI’s explicitly anticompetitive legal terms on students. If the OpenAI data use policy applies to Khan Academy students, they implicitly require every student user of this to not use the output to compete with OpenAI (taken literally, you can’t use what your tutor says to you for anything, since it’s always going to compete with OpenAI) Imagine how dumb it is to say “our thing can do everything. You can use it, but you can’t use it to do anything that competes with us.” Let that sink in. Can you name one thing you can do using the output of a thing that does everything which doesn’t compete with the everything thing? What a shame to flush Khan academy just to hop aboard the hype train. I know I’ll probably get downvoted for being negative but to write so much without clarifying what the “Open” AI legal terms mean for students is actively harmful to student trust. If anyone needs a reason to pity OpenAI, just remember how they betray their true name. That is a profound failure and I would not wish it on anyone.
