How this college teaches

The University's mechanics are not house style; they are the learning sciences, applied:

Tutoring works. Bloom (1984) found students tutored one-to-one performed about two standard deviations above conventional classrooms — the “2-sigma problem.” A page that adapts its depth, checks retrieval, and answers immediately is this archive's attempt at mass tutoring.

Retrieval beats rereading. Testing effects average g ≈ 0.61 (Adesope, Trevisan & Sundararajan, 2017; Roediger & Karpicke, 2006) — hence Retrieval Gates instead of “next” buttons.

Interleaving beats blocking. Mixed practice of related skills roughly doubled test performance in Rohrer & Taylor's classic studies (d ≈ 0.83) — hence practice sets that deliberately mix old folios into new.

Successive relearning compounds. Rawson & Dunlosky: relearning to criterion across spaced sessions took exam-style retention from roughly 20% to 80% — hence SM-2 scheduling, the Fading Ink, and the three-day mastery rule.

Guessing first helps. Prediction before instruction improves encoding even when the guess is wrong — hence “Guess before you learn” and pencil lines that stay beside the ink.

Where the teachings come from

The University did not invent what it teaches. It stands in a long line of people who believed knowledge should be given away, and it points, gratefully, back to them. Its courses follow the shape of open, authoritative curricula and lean on the great freely-licensed libraries of human knowledge:

KindThe shoulders it stands on
Open textbooks

OpenStax · LibreTexts · the Open Textbook Library — peer-reviewed, university-level, free to keep.

Open courseware

MIT OpenCourseWare · Open Yale Courses · Stanford Online — real syllabi, in the order they are really taught.

Public-domain library

Project Gutenberg · the Internet Archive · Wikisource · HathiTrust — the written record, out of copyright and into the commons.

Reference & data

Public-domain reference works · standards bodies · open government data — for the facts a teaching must get right.

Museums & science

The Met, Smithsonian & NASA Open Access · the Biodiversity Heritage Library — which also lend the University its plates.

The University is not affiliated with these institutions; it honours their example. The learning-science claims above are cited to their studies.
