About me

I am Director of PRIM and Senior Lecturer at the Department of Teaching and Learning. PRIM is a research and test development group focusing on the assessment of knowledge and competencies, primarily in mathematics.

My work concerns assessment and large-scale educational measurement in mathematics, at the intersection of research, test development and national educational assignments. I have overall responsibility for the national tests in mathematics for Grades 3, 6 and 9, as well as for Mathematics Level 1 in upper secondary school. I am also the national research lead for mathematics in the international studies PISA and TIMSS in Sweden.

In addition, I am a member of the Swedish expert group for the PIAAC survey, the Swedish National Agency for Education’s expert group for international large-scale assessments, and an expert group for national tests in Norway.

I am also engaged in the research school Assessment of Knowledge in Educational Systems – ASSESS – as coordinator, steering committee member and supervisor. I am the main supervisor of five doctoral students within the research school.

Teaching

I teach primarily in the areas of assessment, quantitative methods, and large-scale national and international assessments in mathematics. My teaching is mainly at the advanced and doctoral levels.

I am the main supervisor of five doctoral students within the research school ASSESS.

Research

My research focuses on assessment and large-scale educational measurement in mathematics, with particular interest in validity, interpretation and the use of results.

A central research interest is how results from international and national assessments can be understood in relation to the knowledge they are intended to measure and to the contexts in which the results are used. This includes questions about how mathematical knowledge is represented in large-scale studies, how results can be interpreted in a national context, and what consequences different uses of these results may have.

I am also interested in assessment and test development in mathematics more broadly, particularly questions concerning national tests, assessment formats, digitalisation, rater variation, and students’ opportunities to demonstrate their mathematical knowledge.
