Mean number of correctly answered shifted ruler problems in combined analysis utilizing findings from Experiments 1, 2, and 3. The model revealed that children in the DE + SA condition maintained their learning at the follow-up session more so than those in the DE alone condition. Both groups outperformed the children in the SA alone and BAU conditions at post-test and follow-up. Error bars represent ±1 standard error of the mean. DE = disconfirming evidence; SA = structural alignment; BAU = business-as-usual.
