2 The frequency of nonunderstandings was negatively correlated with learning gain in FULL: r = −0.47, p < 0.005, but not significantly correlated with learning gain in BASE: r = −0.09, p = 0.59.
in both conditions the frequency of non-understandings was negatively correlated with user satisfaction: FULL r = −0.36, p = 0.03, BASE r = −0.4, p = 0.01.
