Assessment

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.

Evidence against

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

  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.

  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.

  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.
