Application Of Multivariate Rasch Models In International Large-Scale Educational Assessments, Ray Adams, Margaret Wu, C Carstensen Dec 2005

Application Of Multivariate Rasch Models In International Large-Scale Educational Assessments, Ray Adams, Margaret Wu, C Carstensen

Prof Ray Adams

In large-scale educational assessments, such as the Programme for International Student Assessment (PISA) and the Trends in International Mathematics and Science Study (TIMSS), a primary concern is with the estimation of the population-level characteristics of a number of latent variables and the relationships between latent variables and other variables. Typically these studies are undertaken in contexts in which there are constraints on sample size and individual student response time, yet there are high expectations with regard to the breadth of content coverage. These demands and constraints have resulted in such studies using rotated-booklet designs, with each student responding to a ...

International Student Assessment For The New Millennium, Ray Adams

Prof Ray Adams

The author briefly describes the OECD initiated project, 'Program for International Student Assessment' (PISA), in which over 100,000 15 year old students from 4000 schools in 26 countries will participate. A major focus of the project is the assessment of wider knowledge, skills and competencies in literacy, mathematics and science areas.


Applications Of Item Response Theory In The Third International Mathematics And Science Study, E Gonzalez, Ray Adams, Marg Wu Dec 1996

Applications Of Item Response Theory In The Third International Mathematics And Science Study, E Gonzalez, Ray Adams, Marg Wu

Prof Ray Adams

The Third International Mathematics and Science Study (TIMSS) is a survey of mathematics and science achievement sponsored by the International Association for the Evaluation of Educational Achievement. With more than 45 participating countries, three target populations, more than thirty languages, 15,000 schools, more than half a million students, TIMSS is the largest and most ambitious international study of educational achievement ever undertaken. Students participating in the assessment were administered one of eight achievement tests that contain items in mathematics and science, using a variety of item formats. As TIMSS is an international study, many audiences will look at the ...
