Subclaims¶

q1 i? Free choice about AI is exercised almost entirely outside the classroom, so the framework asks of each lever how far its setting reaches into the unsupervised moment. → Halani 2026

q1 · i? · theoretical · r3

Theoretical argument of the paper: at 10 p.m. the teacher and peer agents of formative assessment are absent and the learner sits with a fourth agent, so the paper defines "Reach is the question of which levers are still set at that moment." Reach is a property of a lever's setting, not of the lever itself.

"Reach is the question of which levers are still set at that moment. It is an organizing question of this framework, because free choice about AI is exercised almost entirely outside the classroom."
