The Application of an Extreme-Types Model to a Domain-Referenced Diagnostic Arithmetic Test.
Sadowski, Barbara R.
The purpose of this research was to investigate the diagnostic validity of the Maryland Diagnostic Arithmetic Test (MDAT) as a group-administered test. The MDAT is a domain-referenced diagnostic test consisting of several sub-tests covering the content of elementary school arithmetic from sets to non-negative rational numbers. Forty-five non-overlapping domains were investigated using the extreme types model to determine homogeneous domains. Twelve other domains which were determined a priori were also investigated. The results of the group-administered MDAT provide some evidence for the validity of the MDAT as a diagnostic test. (Author/MK)
