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 due to an incomplete …

The Implications Of Halo Effects And Item Dependencies For Objective Measurement, T Mcnamara, Ray Adams
Prof Ray Adams
Analysis of data from performance-based language tests presents the problem of dealing appropriately with bundles of items that are linked to particular tasks. The authors use recent developments in Rasch modelling which allow analysis of bundles of items (or sets of ratings) to examine the extent of dependence between items and ratings, and they explore the implications of those dependences on the assessments. Data from two performance assessments are used in two studies of this problem.

Interpreting The Parameters Of A Multidimensional Rasch Model, W Wang, M Wilson, Ray Adams
Prof Ray Adams
This chapter introduces the multidimensional random coefficient multinomial logit model (MRCML) which can be applied to multidimensional polytomous test items. Two examples of real data analyses are followed to demonstrates the applications of the MRCML. A detailed discussion is made of interpretation of item parameters, in comparision to those derived from their corresponding unidimensional Rasch measurement models. Finally, it provides some guidelines for constructing scoring matrices and the corresponding models to aid parameter interpretation.

ACER Conquest is a computer program for fitting item response and latent regression models. It provides a comprehensive and flexible range of item response models to analysts, allowing them to examine the properties of performance assessment, traditional assessments and rating scales. This manual examines ACER ConQuest in detail, includes a tutorial and coverage of technical matters.
