How to Accelerate Learning & Improve Education | Joe Liemandt

KEYPOINTS

• 01

  Schools gave universal access; the next goal is universal learning

  The K–12 classroom model came from Prussia about 100 years ago, when society first set out to educate everyone. Around 30 students per teacher was what that goal could afford. Liemandt, principal of Alpha School, argues that kids now have access, but how much they learn over 12 years varies hugely. He believes AI makes it possible, for the first time in 50–100 years, to redesign how learning happens.

  One-on-one tutoring to mastery is the gold standard

  He cites Benjamin Bloom's 1980s 'two sigma' paper: individually tutored students who learned to mastery performed about two standard deviations higher, roughly top 2%. Parents' fixation on class size, he says, is really a proxy for getting closer to one-on-one. The part people forget is mastery, not just the tutor.

• 03

  Alpha's model: about two hours of AI-guided academics, then life skills

  Students do roughly two hours a day of individualized lessons, and Liemandt says they learn about twice as fast as peers. He stresses this isn't a chatbot. Dropped into a normal school, he says, chatbots get used to cheat by about 90% of kids. Afternoons go to workshops on building, sports, entrepreneurship and public speaking, led by adult 'guides' rather than academic teachers. He says 100,000 people applied for those roles last year.

• 04

  Mastery has three layers

  First, can you solve a problem at all? Second, true mastery means doing 10 hard problems, not three easy ones. Third, can you still do them a month or two later? That calls for spaced repetition rather than cramming. American schools, he says, move kids along with an 80% 'B,' leaving holes. His analogy is a basketball coach who wouldn't practice dunks with a team losing the ball 20% of the time; 85% isn't acceptable.

• 05

  Fluency frees working memory

  We have only a few working-memory slots. If you know 7 × 8 = 56 cold, it costs nothing; if you have to calculate it, it uses up slots needed for a multi-step algebra word problem. So, he says, kids who struggle in algebra usually have a third-grade math-facts problem, not an algebra problem. Gifted kids, who have the most slots, often skip writing down their work and hit this wall later.

• 06

  Material must sit at the right level

  What you know is the base for what you can learn. Give someone material that's too hard, like an MCAT to a non-biologist, and no amount of 'grit' or 'growth mindset' helps. You have to roll them back to where they actually are and build up. AI can generate the exact missing lessons and set an individual pace.

• 07

  Measure growth rate, not achievement, and remove the blocks

  Alpha benchmarks each student against peers at the same percentile. Its claim is that top-1% students learn twice as much in two hours as other top-1% students learn in a full day, which Liemandt says rules out a simple rich-kid selection effect. Guides' daily job is to find each child's mental block, such as middle-school girls convinced 'I'm not good at math,' and remove it.

• 08

  Paying kids can work, he argues

  Liemandt says paying for mastery doesn't destroy motivation in their experience, though he acknowledges the self-determination-theory debate. Alpha pays students $1,000 to reach the top 1%. Against roughly $20,000 per pupil per year in public school, or about $240,000 over K–12, he calls small cash incentives cheap. Public schools are legally barred from paying students cash.

• 09

  In traditional schools, family income predicts scores best

  He says the top predictor of test scores is family income, with IQ secondary. Then come IQ and Big Five conscientiousness: natural 'grinders' who do every problem in the book are running a mastery system on themselves. Smart kids without that trait struggle in time-based schools.

• 10

  Kids want high standards and hard things

  Liemandt says high standards are key to a child's happiness, not a source of stress. Over 90% of Alpha students say they love school, and 40–60% said they'd rather go to school than on vacation, depending on the vacation. In the past year, 85% of parents said they had seen their child do something they thought was impossible for that age.
