Description¶
A study-developed assessment by Morra et al. that diagnoses sixth- and seventh-graders’ rational-number understanding using capacity-graded item subsets.
Components¶
Claims¶
- Rational-number CCS test performance is predicted by working memory capacity and, to a lesser extent, by intrusion errors in the listening span [+M]
- Two subsets of rational-number CCS items demand working memory capacities of 4 or 5 units respectively [+M]
