Five randomized trials during school disruptions found gains from roughly 20 minutes of weekly, level-targeted phone tutoring. Division accuracy in the calls-plus-SMS arm was 13.5 percentage points above control.<\/p>\n

The active ingredient was pedagogy, not the device: tutors asked questions and adjusted feedback to each child\u2019s level. Text messages alone produced smaller, less consistent results.<\/p>\n

Who delivered it?<\/h2>\n

Trials compared NGO aides and government teachers; Nepal and the Philippines randomized the delivery model.<\/p>\n

Meaning of 13.5 points<\/h2>\n

Control accuracy was 14.6%, so the absolute gain was a 92% relative increase. Average effects were 0.30\u20130.35 standard deviations.<\/p>\n

Could governments deliver?<\/h2>\n

Government teachers improved 0.40 operation levels in pooled tests and NGO aides 0.30, but national-scale and long-term effects remain unknown.<\/p>\n

Cost<\/h2>\n

Authors estimate about four years of high-quality instruction per US$100. Local telecom, staffing and implementation costs can change that comparison.<\/p>\n

Next check<\/h2>\n

Scale-ups should track participation, retention, classroom integration and caregiver burden. The method supports continuity; it does not replace school.<\/p>\n
