PROOF POINTS: Only a quarter of federally funded education innovations benefited students, report says

The Hechinger Report

Of the 112 properly evaluated grants, the most common result was a null finding, meaning that the intervention didn’t make a difference. There are two reasons that a study can end with a null result.

Wrong! Free computers don’t affect educational outcomes

The Innovative Educator

The estimated null effect is consistent with survey evidence showing no change in homework time or other "intermediate" inputs in education.

PROOF POINTS: Uncertain evidence for online tutoring

The Hechinger Report

Statistically, it was a null result. The results were less sanguine in another study that looked at pairing volunteer college students with low-income middle schoolers in the Chicago area.
