Transmissionism

One-line definition: The (false) notion that knowledge can be directly transmitted from teacher to student, “like transcribing text from one page onto another.”

How sources describe it

• Andy Matuschak in Why Books Don’t Work: the implicit model behind both lectures and books — “the lecturer says words describing an idea; the class hears the words … then the class understands the idea.” “It’s the notion that knowledge can be directly transmitted from teacher to student, like transcribing text from one page onto another.”
• The model is “so thoroughly discredited that ‘transmissionism’ is only used pejoratively, in reference to naive historical teaching practices.”
• The deeper claim: books and lectures didn’t choose this model — they “accidentally (and mostly invisibly) evolved around” it because the form of the medium (sequences of words read in order) silently assumes “people absorb knowledge by reading sentences.” The alternative model — to understand something, you must actively engage with it — would transform the medium.

Where it shows up

• Why Books Don’t Work — the load-bearing villain of the essay; explains why both books and lectures fail to convey knowledge reliably.

• Metacognition — the skillset readers must supply themselves precisely because the medium offers no real cognitive model.
