Modelling Mathematics Problem Solving Item Responses Using A Multidimensional Irt Model, Margaret Wu, Ray Adams Sep 2006

Modelling Mathematics Problem Solving Item Responses Using A Multidimensional Irt Model, Margaret Wu, Ray Adams

Prof Ray Adams

This research examined students' responses to mathematics problem- solving tasks and applied a general multidimensional IRT model at the response category level. In doing so, cognitive processes were identified and modelled through item response modelling to extract more information than would be provided using conventional practices in scoring items. More specifically, the study consisted of two parts. The first part involved the development of a mathematics problem-solving framework that was theoretically grounded, drawing upon research in mathematics education and cognitive psychology. The framework was then used as the basis for item development. The second part of the research involved the ...

Application Of Multivariate Rasch Models In International Large-Scale Educational Assessments, Ray Adams, Margaret Wu, C Carstensen

Prof Ray Adams

In large-scale educational assessments, such as the Programme for International Student Assessment (PISA) and the Trends in International Mathematics and Science Study (TIMSS), a primary concern is with the estimation of the population-level characteristics of a number of latent variables and the relationships between latent variables and other variables. Typically these studies are undertaken in contexts in which there are constraints on sample size and individual student response time, yet there are high expectations with regard to the breadth of content coverage. These demands and constraints have resulted in such studies using rotated-booklet designs, with each student responding to a ...
