An analysis of the critical thinking items showed a strong trend toward positive gains, albeit just short of significance, t (145) = 1.818, p = 0.06, Cohen’s d = 0.157 ( Figure 11 ).

The items selected were difficult because we wanted to rigorously discern genuine gains—thus the pre-test to post-test difference was not large, albeit highly significant with a substantial effect size as shown by the Cohen’s d .
