Accurate interpretations of large-scale assessment results and sound judgments about students' mathematical literacy depend on these assessments' validity and reliability. One important type of evidence towards this validation is the dimensionality analysis, which explores the conformity between the intended factorial structure (related closely to…

Wang, Shudong; McCall, Marty; Jiao, Hong; Harris, Gregg – Online Submission, 2012
The purposes of this study are twofold. First, to investigate the construct or factorial structure of a set of Reading and Mathematics computerized adaptive tests (CAT), "Measures of Academic Progress" (MAP), given in different states at different grades and academic terms. The second purpose is to investigate the invariance of test…

Lawrence, Ida M.; Dorans, Neil J. – 1987
Six editions of Scholastic Aptitude Test-Mathematical (SAT-M) were factor analyzed using confirmatory and exploratory methods. Confirmatory factor analyses (using the LISREL VI program) were conducted on correlation matrices among item parcels--sums of scores on a small subset of items. Item parcels were constructed to yield correlation matrices…

Medina-Diaz, Maria – 1992
The cognitive structure of an algebra test was defined and validated using the linear test model (LLTM) and quadratic assignment (QA) techniques. The LLTM is an extension of the Rasch model with a linear constraint that describes item difficulty in terms of the cognitive operations required to solve the item. The model permits the specification of…

Stein, Terri; Frankiewicz, Ronald G. – 1985
The evaluation of the content validity of the Functional Academic Skills Tests (FAST) are described. The FAST was designed to assess the competency of inservice teachers in the Houston, Texas Independent School District in basic reading, writing, and mathematics skills. Validation standards were based on the Equal Employment Opportunity…
