Today: the five AI headlines of the day → and the AI Wiki
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-2026-001 · Evidence A · P1

A six-week teacher-supported after-school generative-AI tutoring program in Edo State produced a 0.31 standard-deviation gain on a combined English, AI-knowledge and digital-skills assessment and a 0.23 standard-deviation gain on English, the primary outcome, versus business as usual.

What this does not establish

Does not show that unguided chatbot access, enrolment, course completion or any AI tutor produces the same learning gain.

Counterevidence & uncertainty

Custom short-term assessments and a business-as-usual rather than attention-matched control limit transportability; the 1.5–2 years comparison is a modeled equivalence, not observed follow-up.

What would change the reading

Seek peer-reviewed replication, delayed retention, standardized tests and active-control comparisons.
