Pisa : Frequently Answered Criticisms, Ray Adams
Pisa : Frequently Answered Criticisms, Ray Adams
Prof Ray Adams
Studies such as PISA that attempt to compare outcomes across educational systems are expensive and difficult to implement. Further, the results of such studies are routinely criticized by educational commentators - particularly when the results are not consistent with their preconceived ideas about the relative merits and efficiencies of various educational practices and systems. This chapter discusses what is done to ameliorate the threats to the validity of PISA in five areas often targeted by commentators and reviewers as sources of invalidity in international comparisons. The five areas discussed are: (1) sampling - are the samples of students who undertake …

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 …

Broadening Assessment, Improving Fairness? Some Examples From School Science, Jan Lokan, Ray Adams, Brian Doig
Prof Ray Adams
Following a review of equity issues in testing, especially in relation to science, two assessment programmes in school science, each of which was designed both to probe a range of aspects of student performance and for use in a large-scale study, are discussed. Both have been developed and used in the 1990s, one is Australia only and the other in many countries. The programmes and the range of aspects they attempt to assess are described and results are cited for several groups of students. Issues of fairness through broadening of large-scale assessments to include tasks requiring students to construct their …

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.
