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 ...


Reliability As A Measurement Design Effect, Ray Adams Dec 2004

Reliability As A Measurement Design Effect, Ray Adams

Prof Ray Adams

Test reliability is a concept central to classical test theory and it is commonly stated as a requirement that a test attain a certain level of reliability before it be considered of sufficient quality for practical use. This article discusses the role of reliability in item response theory, and in particular the role of reliability in contexts where matrix sampling designs are used and concern is with the estimation of population parameters rather than the measurement of individuals. The concept of a measurement design effect is introduced. This concept parallels the concept of sampling design effects, in that it describes ...


Response To 'Cautions On Oecd's Recent Educational Survey (Pisa), Ray Adams Aug 2003

Response To 'Cautions On Oecd's Recent Educational Survey (Pisa), Ray Adams

Prof Ray Adams

This paper refers to the work of S J Prais who questioned the outcomes of the Organisation for Economic Cooperation and Development's PISA survey of the reading, mathematics and science attainments of fifteen year-olds. Prais suggested that methodological flaws in Programme for International Student Assessment (PISA) had resulted in an apparent improvement in the attainment of British students, particularly when compared to their Swiss and German counterparts. This paper responds to Prais's criticisms, noting that when Prais's conjectures are tested with empirical data they are not supported. The author argues that many of Prais's criticisms are ...

Student Progress, Charting Of, Geoff Masters, Ray Adams, M Wilson

Prof Ray Adams

This article looks at the charting of students' progress. It examines learning as an active process, conventional achievement testing, testing for conceptual understanding, constructing ordered outcome categories, and collecting observations.
