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 ...

Learning About Teaching : Using Video, Hilary Hollingsworth

Dr Hilary Hollingsworth

This article describes some Australian research and professional development projects that use classroom video data, and explains some of the positive outcomes, as well as some of the challenges, of these projects. A variety of methodologies have been used to collect, store, retrieve, code, navigate and analyse classroom video data. These include CD-Rom, DVD and web streaming to dedicated software platforms. Video is used to preserve classroom activity so that it can be 'slowed down' to enable detailed examinations of teaching and learning from multiple perspectives, reveal alternatives through comparative analysis, and stimulate discussions about choices related to teaching learning ...
