Running head: MODELING LANGUAGE COMPONENTS IN MATH ITEMS Modeling Language Components in Mathematical Items Using Multiple-Random-Effects IRT Models

چکیده
Language components in mathematical word problems might have some profound impacts on the problem solving processes engaged by examinees. Such impacts usually do not occur uniformly across examinees, but rather are the results of the interactions between the characteristics of the mathematical item and the cognitive properties of the particular examinee. This study examined such impacts through a multiple random-effects IRT modeling approach, which has the benefit of modeling the individual-specific impacts of the language components on mathematical problem solving, in addition to the average effects of such components across the testing sample. Results showed that substantial variations among examinees of the impacts from such language components were found for the examinee sample.

متن کاملGeneralizability in Item Response Modeling
An approach called generalizability in item response modeling (GIRM) is introduced in this article. The GIRM approach essentially incorporates the sampling model of generalizability theory (GT) into the scaling model of item response theory (IRT) by making distributional assumptions about the relevant measurement facets. By specifying a random effects measurement model, and taking advantage of ...
