Tutoring

Tutoring

The core of the education argument in Marc Andreessen’s It’s Time To Build: we know that one-to-one tutoring yields a two-standard-deviation gain — the Bloom two-sigma effect — and we have the internet, so the open question is “why haven’t we built systems to match every learner with a tutor?” Andreessen frames this as a build failure rather than a knowledge failure: top universities teach only a microscopic share of the world’s 18-year-olds, the last major K-12 innovation was Montessori (1960s), and fifty years of education research never reached deployment.

In Kyle’s wiki the thread runs straight into Synthesis School, which he tags as the worked example of the “build new education systems” call — tutoring-at-scale as the thing the internet should make possible. The concept therefore sits at the junction of the build-mandate (Andreessen) and a concrete company instantiating it (Synthesis), with the Bloom two-sigma result as the empirical warrant for why one-to-one instruction is worth re-engineering.

Context: Benjamin Bloom’s 1984 “2 sigma problem” found that students tutored one-to-one performed about two standard deviations better than students in conventional classrooms — a benchmark frequently invoked in edtech to argue that personalized instruction can dramatically outperform mass schooling.

Where this appears

  • It’s Time To Build — the education-building argument: match every learner with a tutor, citing the Bloom two-sigma effect.
  • Synthesis School — tagged as the build-new-education-systems / tutoring-at-scale example.
