Direct linkIbrahim Burak Ölmez; Andrew Izsák – Journal of Mathematics Teacher Education, 2024
In prior work, we fit the mixture Rasch model to item responses from a fractions survey administered to a nationwide sample of middle grades mathematics teachers in the United States. The mixture Rasch model located teachers on a continuous, unidimensional scale and fit best with 3 latent classes. We used item response data to generate initial…

Peer reviewedBirenbaum, Menucha; Tatsuoka, Kikumi K. – Applied Measurement in Education, 1993
The item-response-theory-based (IRT) rule-space model was used to diagnose student knowledge about how exponents behave in multiplication and division in a sample of 431 tenth-grade students. Implications for using feedback from the rule-space model in instruction and assessment are discussed. (SLD)
