q3 · i? · causal · r1

System-internal improvement analysis: a binomial NLME model with one group per user and key skill was fitted to all tasks children solved at their key skills, measuring learning rate over the training period. No standardized effect size printed.

"The resulting model (Fig. 6) for all skills exhibits an estimated mean improvement of 21.8 % (95 % confidence interval = [0.21 0.23])."
