Subclaims¶

q2 i? Proportions of variance explained increased steadily from Knowledge to Application and then decreased from Analysis to Evaluation, contradicting the expectation of steadily increasing direct links under the cumulative hierarchy. → Madaus 1971

Madaus, George F.; Nuttall, Ronald L.; Woods, Elinor M. (1971). A Causal Model Analysis Suggests Modification of the Cumulative Hierarchical Structure Assumed in Bloom's Taxonomy of the Cognitive Domain. https://eric.ed.gov/?id=ED054203

q2 · i? · the article prints no effect size for this finding · associational · r2

Pattern observed in Tables 2-4 and Figure 3 summarizing proportions of variance across the 16 replications. The authors note that if lower-level behaviors were cumulatively integrated, variance explained should increase steadily rather than decline at the upper levels.

"The curvilinear pattern of the proportions of variance explained over the six thxonomic levels should be noted.The proportions of variance increase steadily at the lower levels from Knowledge to Application and then decrease at the higher levels from Analysis to Evaluation."
