Cronbach α for the rubric across its five levels and for the action map across its variables
(relative frequency of mnemonic actions, relative frequency of cognitive actions, relative
frequency of perceptual actions, number of actions, and number of loops) are reported in
Table 2. In spite of the small sample in this study, Cronbach α was moderate high, indicating
a reasonable internal consistency for the action map.
