   #9 – From Families to Schools

   What we covered: – It's been a few months since our last podcast, and in that time, we've seen a huge increase in the number of schools wanting to use Math Academy for this upcoming school year. – Now, if you've been following our podcast, you already know that one of the recurring themes at Math Academy is that before you automate something, you gotta first do it manually so you really understand what you're automating. ('Cause if you skip that step, and you jump straight to automation without really getting your reps in, getting your arms around the problem, you end up building a whole bunch of infrastructure that not only does not solve the problem, but in fact just scales your confusion. And then you gotta unwind all of it later. It puts constraints on more things that you build once you actually know what you're doing. It's just terrible.) – So just like Jason did with individual customers at the beginning, onboarding hundreds of people over hour-long Zoom calls, getting those manual reps that have been really such a vital component of building a system that really solves the problem... Well, that's what he's doing again with schools. And that's what we'll talk about in this episode. – We'll talk about the anatomy of Jason's onboarding sessions, why onboarding a school is way more challenging than onboarding an individual, and what successful school implementations look like. In particular, why it's most sustainable for each school to start small, lock in some wins, get solid in managing students who are using the system, and then gradually scale up to more classes and teachers. Outline: 2:44 - Onboarding lots of schools recently 6:39 - Different types of customers 9:13 - Why conversations with customers matter 15:05 - Streamlining inevitable school sign-ups 17:10 - Identifying high-leverage tasks 18:35 - Manual school account creation 19:30 - Manual processes make sense in the beginning 22:05 - Learn the workflow before automating 23:28 - The hidden costs of new software features 25:25 - Keeping product scope minimal 27:40 - Anatomy of a typical school onboarding session 37:26 - Intentionally growing without a sales team 40:11 - Schools promote students without requiring mastery 42:20 - Why every school onboarding call is different 43:48 - Building automated school onboarding 51:05 - Validate success at a small scale before scaling up 55:30 - Sustainable growth over rapid expansion 58:41 - Looking ahead: proctored exams Follow on X: Math Academy - https://x.com/_MathAcademy_ Justin Skycak - https://x.com/justinskycak Jason Roberts - https://x.com/exojason

   #8, Part 2 – Failure Modes in Teaching

   What we covered: – In elementary school, there's often an intense focus on conceptual understanding, but not enough time spent building real fluency with core skills. And this has left many kids without automaticity on basic things like multiplication facts. Math is extremely hierarchical, and when students don't have the basic facts at their fingertips, they quickly run into bottlenecks as the material gets more complex. – Sure, drills can be made more fun, but the bottom line is that they have to get done. In high school and college, most of the class time is spent copying notes from the board -- and these notes are often copied by the instructor from a textbook or from other source material. This game of telephone through transcribing is just a performative activity. It's theater. It's passive and it does next to nothing for learning and retention. – In upper level college math courses especially, students may only receive short weekly problem sets, which really aren't enough to build mastery, even if the problems are really hard, because students just spend most of their time flailing around. – The bottom line is that students need reps: lots of them, building up scaffolding to the highest, hardest levels that they're expected to reach. High school assignments tend to be better in that regard, but students frequently don't receive timely feedback, and often their work isn't even graded for accuracy. That feedback loop is so critical: without it, students won't know what they're doing wrong or how to improve. – So rather than just pattern matching to how math has traditionally been taught, what actually makes training effective? There's a few core principles: 1) Maximize the amount of time spent actively learning, interleaving minimum effective doses of explicit guided instruction active practice. 2) Make sure students are consistently working at the edge of their abilities: not bored, but not overwhelmed. 3) Provide frequent, timely feedback so students can adjust and improve. These principles should be applied to math education and training environments everywhere. Outline: 0:00 - Introduction 3:13 - Professors often wing pedagogy 5:37 - Too much class time is spent transcribing notes 7:41 - College problem sets are too short 12:53 - A lot of homework isn’t even graded for accuracy 18:22 - Copying notes in class is performative productivity 22:29 - Alex taught math courses at University College London 25:35 - Teaching is often an annoying obligation for research professors 30:03 - The bar for teaching is on the floor 32:34 - Even football practices often waste players’ time 34:20 - Most training is inefficient because people pattern match to the status quo 34:57 - First principles for effective training 37:13 - Too many models can paralyze and become a crutch for kids 39:24 - Kids can get stuck using training wheels in math forever 42:05 - Non-standard methods are often distracting and inefficient 46:18 - Designing 6th-8th grade courses to align with school curricula 52:30 - Conceptual understanding without ability is useless 55:17 - Skills practice can and should be gamified Follow on X: Math Academy - https://x.com/_MathAcademy_ Justin Skycak - https://x.com/justinskycak Jason Roberts - https://x.com/exojason Alex Smith - https://x.com/ninja_maths

   #8, Part 1 – Role of Teachers in the Math Academy Classroom

   What we covered: – A lot of schools have recently begun using Math Academy in their classrooms. And one of the biggest benefits of using Math Academy is that it automates all the mechanical parts of teaching, like writing questions, keeping track of what students know and what they don't know, monitoring student progress, assigning extra practice when needed, grading, all that grindy stuff. – None of these tasks is enjoyable. They suck. Just ask any teacher. I mean, we grinded through all that back when we were teaching ourselves, and it takes so much effort just to get even a halfway decent approximation of doing it right. And there's just a limit to how well that you can do it if you're doing it manually. It's the whole reason why we built the system. – And what that system does, what Math Academy we does is it frees up teacher bandwidth to focus on the human elements of teaching: building relationships, connecting what students are working on to their own unique interests. Those kind of things that enhance the learning experience, but that really can't replace skills practice. – I mean, in-class projects can be great, but only if students have the prerequisite knowledge to be successful with them. If they don't, then projects are frustrating, and the students who understand the material will end up doing all the work and carrying everybody else, who will learn next to nothing. It's inefficient and frustrating all around unless students have their skills in place. – Ultimately, if students don't master the math in each class, they'll be unprepared for the next one. And in a subject as hierarchical as math, these gaps compound quickly. True empowerment isn't simply telling students they have potential. It's making sure they actually have the real skills to move forward and realize that potential. Outline: 00:00 - Introduction 02:56 - What is the teacher’s role alongside Math Academy? 05:37 - Math Academy frees up teachers to do the human parts of teaching 07:03 - Projects are great if students have the prerequisite skills 07:42 - Drills without context are boring 08:43 - Games without skills are inefficient 11:14 - Build fun activities on top of a solid foundation of skills 12:15 - Teachers can tailor the class to the students’ preferences 13:28 - Implementing mastery learning is too much work for a single teacher 15:27 - Doing projects without prerequisites is frustrating 16:57 - True empowerment is giving kids the skills they need to succeed 19:30 - Missing skills compound in hierarchical skill trees 24:06: Lack of automaticity in lower level skills slows down higher level tasks 27:14 - The MA team builds and improves courses through experience 29:21 - The MA team targets tasks with low pass rates for additional scaffolding 31:03 - Alex built knowledge graph intuition through years of experience 37:40 - Social media enforces hyper-accountability 39:19 - Differential equations courses are often a hodgepodge of disjointed techniques 43:20 - Math Academy university courses are a superset of elite university content 45:18 - Differential equations is a highly branching subject 49:21 - The breadth of Differential Equations makes it often poorly taught *Follow on X:* Math Academy - https://x.com/_MathAcademy_ Justin Skycak - https://x.com/justinskycak Jason Roberts - https://x.com/exojason Alex Smith - https://x.com/ninja_maths

   #7, Part 2 – Earning the Right to Scale

   What we covered: – As Math Academy has grown over the past year, we're getting a better sense of general do's and don'ts when scaling a startup. We've learned hard lessons about overloading the database, the task processor, and our team, requiring numerous infrastructure and process updates. – Schools have been using the system and we've built plenty of additional features to, among other things, accommodate unique billing schemes and make it easy for teachers to manage classes on the system. – We've intentionally grown organically and were self-funded, which forced us to do things manually at the beginning. Years ago, we taught math classes in person and Jason onboarded our first online users on hundreds of hour-long individuals and calls. These were crucial experiences to learn who our customers are, what they want from the product, and common failure modes. – In our experience, doing things manually at the beginning ensures that you 1) build a product that customers actually get value from, and 2) you don't clutter your product with unnecessary bells and whistles that don't add value. In other words, you have to do the manual work to earn the right to scale. Outline: 0:00 - Introduction 2:18 - Building infrastructure to handle increasing load 3:41 - Bringing on AWS expertise to robustify the backend 4:22 - An overloaded database enters a new realm of physics 5:50 - Prioritizing execution over perfection in start-ups 6:33 - Paying the bill for accumulated infrastructure debt 7:53 - Improving job prioritization of the task processor 9:52 - Benefits of scaling organically 11:42 - Wisdom is the result of failures 12:18 - There is no substitute for experience 13:17 - Focusing on solving problems, not advertising 14:48 - Upgrading with surgical precision 15:35 - The pain-point compass 17:04 - Managing finite time and resources 18:27 - Development of the gravity feature 20:42 - Gravity is a suggestion, not a hard override 22:25 - Limiting gravity to avoid cognitive overload 28:29 - Balancing customization and customer confusion 31:28 - The feature sandbox 33:58 - Increasing volume of customer support emails 35:22 - Additional infrastructure requirements for schools 36:18 - Learning about the customer through direct interaction 38:14 - Step 1: Manually added schools using spreadsheets 40:22 - Step 2: Developed tools to handle specialized school requests 41:23 - Step 3: Goal is 100% self-service sign-ups for schools 42:32 - Solve the problem manually first, then automate it 43:44 - Why focus on schools? 46:15 - Math Academy goes to college 49:37 - You can’t anticipate every edge case 52:14 - Letting user behavior build the product roadmap 58:54 - Becoming successful means working harder 1:00:24 - The customer support hurdle 1:03:27 - How Justin’s expanding roles drove growth (both personal & company) 1:09:03 - Teaching as market research for Math Academy 1:10:52 - The value of having been inside the trade Follow on X: Math Academy - https://x.com/_MathAcademy_ Justin Skycak - https://x.com/justinskycak Jason Roberts - https://x.com/exojason

   #6, Part 3 – Learning Debt and Skill Insolvency

   What we covered: The dangers of accumulating learning debt: the gap between what you can do and what you need to be able to do. If you miss building up your foundational skills in school or sports, you can get by for a while. You develop some compensatory strategies, like favoring your forehand over your backhand, or using ChatGPT to write all your school essays. But learning debt is like any other kind of debt: it accrues interest and eventually comes due. Over time, the workarounds become more complex. The cognitive load increases. You start avoiding situations that expose the gap, and this is where you hit your ceiling. You can’t pursue an engineering degree if you can’t do algebra. You can’t be competitive in tennis if you can’t hit with your backhand. Learning debt often begins because of a lack of oversight by adults. Parents, teachers, and even coaches sometimes think they’re being nice not telling you that you need to work on your weaker side, or you need to stop using a calculator on your math problems. It feels like nagging, and it can create conflict between adults and learners. So they let it slide. But this failure to hold the line early on inhibits students’ future potential. And when it occurs across many students across many schools, it degrades the whole educational system – leading to the current situation in which many students are totally unprepared for the rigors of college.

   #6, Part 2 – On The Rails and Out Of Scope

   What we covered: – The benefits of short problems. Math Academy problems typically take only a minute or two. This way, students can stay on the rails with lots of reps, successfully building up complexity instead of getting crushed by it from the start. – What goes wrong in college math classes: they tend not to scaffold content very well, forcing students to build their own bridges across knowledge & skill gaps. Weekly problem sets often consist of a handful of hour-long problems that instructors hope students will “self-scaffold” up to. In reality, what happens more often is that students fall off the rails. – Founders of growing start-ups cannot be hands-off. “Things falling off the rails” is the most realistic and most dangerous failure mode, not micromanaging. Founders of small, scaling companies need to be in “founder mode,” not the “manager mode” that CEOs of huge, well-established companies are in. – Within teams, it’s important to let conversations flow out of scope. Every innovation, every solved problem, requires relevant background context, and you often don't know what the full context is beforehand. It's easy to let conversations flow out of scope when you like who you're working with and what you're working on. Outline: 0:00 - Introduction 1:32 - Why Math Academy problems are short by design 9:48 - Long problems dilute reps on the skill that actually matters 11:00 - Isolate the new skill first, then recombine into full problems 14:10 - Typical undergrad math classes: too few problems, too complex from the start 18:07 - The proof skills gap: often assumed and not taught 29:32 - Alignment decay: teams naturally drift out of sync unless continually aligned 35:04 - Small misalignments compound fast 38:28 - Founder mode: stay in the weeds to stay in sync 49:07 - Early, frequent parent communication avoids end-of-term blowups 50:48 - High-trust collaboration requires relentless communication 57:42 - Out-of-scope conversation enables context sharing 59:14 - Over-scoping kills context sharing 1:00:51 - Enjoyment & trust fuel context sharing 1:06:13 - Missing context produces confidently wrong outcomes 1:10:01 - LLMs fail when context is missing 1:11:38 - Humans fail when context is missing 1:14:19 - Online discourse fails when context is missing Follow on X: Math Academy - https://x.com/_MathAcademy_ Justin Skycak - https://x.com/justinskycak Jason Roberts - https://x.com/exojason

   #6, Part 1 – Why Can’t College Students Do Middle School Math?

   What we covered: – A recent report from the University of California San Diego revealed that 1 in 12 incoming freshmen were not proficient in middle school math – basically, anything above arithmetic with fractions. Their existing remedial math course was too advanced for these students, so they had to design even lower remedial remedial math courses. Even crazier, over a quarter of these students had a perfect 4.0 GPA in their high school math courses. – It’s not just UCSD. This is everywhere. A similar thing happened at Harvard, too, having to add remedial support to their entry-level calculus courses. It’s like that movie Olympus Has Fallen, except this time it’s Harvard. It’s a catastrophe. – How did things get this bad? Teachers and administrators face relentless pressure to inflate grades, and during the pandemic many universities went test-optional, removing the only signal that reliably correlated with actual math readiness. That decision simultaneously elevated high school grades to the sole gatekeeping metric, intensifying incentives to inflate them. – This has all coincided with the advent of LLMs, which make it increasingly easy for students to cheat. The result was predictable: grades became untethered from real competence, and multiple cohorts of students entered college without ever having to demonstrate foundational math skills. – Teachers have to play both good cop and bad cop, and there is no avoiding the latter. If you refuse to play bad cop at all, you eventually end up playing it constantly. The best teachers are strict from the start and ease up later, once students understand that hard, honest work is non-negotiable. Outline: 00:00:00 - Introduction 00:02:11 - Freshmen math collapse: 1 in 12 UCSD freshmen don't know middle school math 00:06:45 - Remedial remedial math: UCSD created remediation for remedial math 00:08:40 - Inflated grades: 25% of remedial-remedial students had perfect GPA in HS math 00:10:06 - Test-optional admissions removed the last objective metric 00:12:13 - Pandemic inflation: GPAs skyrocketed 00:14:37 - Removing tests pressures teachers to inflate grades 00:16:52 - Grade-grubbing: endless negotiating, complaining, accusations 00:19:01 - Then vs. now: parents, tests, accountability 00:27:38 - Crisis opportunism: “Never let an emergency go to waste” 00:29:33 - No tests = no knowledge requirements 00:33:28 - Elite collapse: Harvard has the same problem 00:36:31 - No enforcement means no standards 00:37:40 - LLM cheating is trivially easy 00:38:25 - Catching a cheater and turning him around 00:48:46 - Cheating is like taking mob money. Now you’re in, you’re never out. 00:50:41 - Assessments must be done in person 00:55:06 - LLM cheating is often obvious yet hard to prove 00:57:17 - How to prevent cheating on long papers 00:58:28 - Start hardcore, then lighten up gradually 01:01:37 - Good teachers play bad cop when needed Follow on X: Math Academy - https://x.com/_MathAcademy_ Justin Skycak - https://x.com/justinskycak Jason Roberts - https://x.com/exojason

   #5, Part 2 – Getting Kids To Do Hard Things

   What we covered: – Most kids are not intrinsically motivated to do the hard things: practice their soccer drills, do their math homework, eat their broccoli. Getting them to do the hard things often requires gamification and/or incentives. – A little gamification goes a long way. Jason gamified drills for his kids’ soccer team to get the most out of each practice (e.g., “zombie attack”), and it was unreasonably effective. XP and leaderboards on Math Academy are also unreasonably effective. – A good incentive can change kids' behavior overnight. The incentive doesn’t need to be big; it just needs to be something the kid really cares about. Find the thing the kid would rather be doing, and use it to motivate them to do what they’re supposed to be doing. They won’t need the incentive forever; as the kid gets used to the feeling of a new behavior, it gradually turns into a habit that they can maintain on their own. – Even when you’re doing what you love, there will be grindy phases. But kids typically don’t understand this. They might get interested in a talent domain and want to become good enough to build a life around it, while simultaneously resisting doing the hard work to make that happen (i.e., stage 2 in Bloom’s talent development process). It’s often up to parents, who can see the long game, to push their kids through the difficult parts in paths that they find rewarding. – For instance, the most mathematically gifted student Justin ever worked with, who was drawn into math by his own intrinsic interest, still needed to be pushed to learn calculus. Now he’s having the time of his life working on physics-y, calculus-heavy research-level math problems in high school. Even after finding something he loves and is good at, he still needed to be pushed to do the hard work to unlock more of it.

It’s important for parents to help kids push through those grindy phases so that they can unlock more of what they love.

    #5, Part 1 – Building Without Bloat

    What we covered: – Any successful endeavor requires a great team: capable people, who like and trust each other, and have complementary skillsets and ways of thinking. Some modes of thinking cannot be performed at the same time within a single brain. – Accountability requires control. You can’t hold someone responsible for outcomes unless you also give them control over the system that produces those outcomes (though you can set reasonable operational boundaries). – Solve today’s problems today. Smart people can invent endless hypotheticals and build giant solutions to fake problems. Not only does this waste time, but it also burdens the system with complexity that becomes a future straitjacket. Everything you build must be carried forward, so focus on what’s present in front of you, not on imagined futures five steps away. – In a scaling system, the sheer volume of interactions will expose a long tail of bizarre scenarios, almost like rare diseases you’d never anticipate. Users will often try to repurpose software beyond its design, like hauling a trailer with a motorcycle.

    #4, Part 2 – Knowledge Graph Engineering: Mental Models & War Stories

    What we covered: – Building a knowledge graph is like city planning & road construction. Too many prerequisites leading into a single topic creates a cognitive traffic jam. – Elegantly rewiring a live knowledge graph: the evolution of our tooling and automatic validations. How to avoid staging servers & migrations and NOT have it blow up in your face. – UI work takes time and adds complexity, so we spend it on the customer. Internal tools are almost entirely command-line; clickable buttons are for customers. – Justin's transition from research coding to real-time systems. He started with mathy, notebook-driven quant code and had to learn production engineering the hard way. Once he did, it was a massive level-up. – Alex's plan for dealing with "content papercuts" - small issues that pile up. Inspired by Amazon’s “papercuts team.” – Our upcoming differential equations course, the last course in the core undergrad engineering math sequence.

    #4, Part 1 – The Unreasonable Effectiveness of the Knowledge Graph

    What we covered: – Why “problem solving” is often just a vague label people use when they haven’t explicitly enumerated the underlying skills, and how those skills can in fact be exhaustively mapped in a knowledge graph. – How to approach research problems: Alex's PhD journey, top-down familiarity vs bottom-up mastery. – If you have natural talent, use it, but not as a crutch, otherwise you'll stunt your long-term development. Don't turn your blessing into a curse. – The story behind building our SAT prep curriculum: realizing that the standard school curriculum leaves a massive “missing middle” unaddressed; identifying 115+ missing topics to bridge the gap between textbook math and the hardest SAT questions. – Watching the manifold hypothesis play out in test prep: the SAT may appear to allow an astronomical space of possible problem types, but in reality the actual problems live on a compact, highly structured manifold that can be fully enumerated and scaffolded in a knowledge graph.

    #3 – Waging War on Mediocrity: Tales From the Trenches

    What we covered: -- How bureaucracies instinctively reject new ideas like an immune system attacking a foreign organ, and what it takes to keep your project from being "spit out." Concrete example: how Jason & Sandy muscled past institutional resistance to get 8th graders passing AP Calc BC. -- Every system inevitably decays into mediocrity unless someone fights to keep the standards high. The way you keep people, systems, and projects moving is by "horsing" them forward. Concrete example: how Justin kept 8th graders passing AP Calc BC, and what it looks like when a school succumbs to the gravity of mediocrity. -- Justin's math self-study journey in high school: grinding math like a video game, running a secret self-study op inside traditional classes, taking talent development seriously while simultaneously hitting his head on every ledge and making every rookie mistake. Ups and downs, lessons learned, with tons of concrete examples.
