q2 · i? · causal · r?

The abstract reports a ten experimental and ten control school comparison in Utah using the Cooperative Physics Test; equivalence was not tested, only no differences obtained for large and small schools.

"No differences between experi- mental and control groups were obtained with large and small schools."
