What a claim record is How to read this page

One statement, bounded on purpose

The headline is a single claim that a named source supports. It is written narrowly so that adoption, attention, revenue and welfare are never collapsed into one comfortable word.

The three sections below the fold

What this does not establish is the boundary of the evidence. Counterevidence & uncertainty is what argues the other way. What would change the reading is the observation that would move it. A record missing any of the three is incomplete, not merely brief.

Primary routes are checkable

Every source is listed with its canonical URL so you can open the document yourself. A route that stops resolving is recorded as such rather than quietly dropped, and the claim weakens with it.

MWITA-EL-2026-003 · Evidence A · P1

A 2025 crossover randomized trial with 194 Harvard physics students found that a research-designed AI tutor produced larger immediate post-lesson learning gains than an active-learning classroom while students spent less time and reported higher engagement and motivation.

D06 · Creator, Expert, Education & Media Worlds

What this does not establish

Does not establish semester-long retention, generalization beyond physics, or superiority to one-to-one human tutoring.

Counterevidence & uncertainty

Very short intervention at one selective university; authors helped design the tutor and comparison instruction.

What would change the reading

Require multisite replication and delayed/transfer outcomes.
