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 …

This paper describes a plausible values imputation approach for deriving population scores on several language proficiency domains. The approach harnessed a multi-dimensional item response analysis combining student responses, rater judgements and student background variables. The target population was grade one and grade two primary school students enrolled in the Hong Kong schooling system. The raters were local teachers of English employed within the sampled schools. The primary objective of this research was to impute plausible values for data where no data was provided or where rater data was deemed suspect. By necessity, a secondary objective of this study was to …
