q2 · i? · causal · r2

The article's own summary statement in its Conclusions section, based on the two-year randomized trial; no underlying statistic or effect size for the 53% figure is printed in the abstract document, so it is reported as the authors' stated magnitude.

"Students working with the DynEd software learned 53% more than students in the control group, who worked with teachers alone."
