Claim

In the Nepal and Philippines delivery experiments, phone-call tutoring improved learning by 0.40 operation levels with government teachers and 0.30 operation levels with NGO teacher aides.

Main unresolved issue: 7 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:24699160-3023-8894-a712-63414cdb230a

Not yet independently audited.Evidence points both ways.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.Every quoted passage was confirmed on the page when Galedra fetched it.

Why?

Strongest counted support: The delivery comparison directly reports 0.40 operation levels for government teachers and 0.30 for NGO aides. weight 2.000000 evidence

Strongest counted contradiction: A randomized Sierra Leone trial found no learning-score effect from calls by either private or government teachers. weight 0.510000 evidence

Suppressed as dependent: The excerpt directly reports pooled learning improvements of 0.40 operation levels for government teachers and 0.30 for NGO teacher aides.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Leans contradicted.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

Under neighbouring settings of the same model: 0.7394 to 0.8740, a spread of 0.1346.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

A randomized Sierra Leone trial found no learning-score effect from calls by either private or government teachers.

From Live tutoring calls did not improve learning during the COVID-19 pandemic in Sierra Leone Read 2026-09-29 Relevance MODERATE Steps 1 Counted

This is a different country and call pedagogy, so it challenges generalization rather than directly overturning the Nepal/Philippines estimates.

Qualifications

The phone-call tutoring intervention consisted of weekly 20-minute tutorials delivered for eight weeks.

From Mobile education builds resilience during shocks in five countries Read 2026-09-29 Relevance DIRECT Steps 0 Counted

Adds the intervention duration and weekly session format.
The Nepal and Philippines trials occurred amid COVID-19 school disruption and lengthy closures.

From Mobile education builds resilience during shocks in five countries Read 2026-09-29 Relevance MODERATE Steps 0 Counted

Limits the setting to COVID-19-related education disruption.
The 0.40 and 0.30 operation-level effects are pooled across Nepal and the Philippines, not separate country estimates.

From Mobile education builds resilience during shocks in five countries Read 2026-09-29 Relevance DIRECT Steps 0 Counted

Clarifies that the reported effects are pooled across the two delivery-model contexts.
The Sierra Leone authors attribute the differing result partly to radio-linked, less personalized call instruction.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
