Academic interests

My research focuses on the development of educational scales, primary within the field of mathematics education. 

Substantive Focus:

  • Mathematics didactics
  • National assessment systems
  • Norwegian context
  • Numeracy

Methodological Focus:

  • Differential Item Functioning
  • (Multidimensional) Item Response Theory
  • Scale development
  • Test-linking and vertical scaling

My current work is under the umbrella project Educational Measurement in the Norwegian Context, with principal investigators Rolf Vegar Olsen and Sigrid Blömeke.

Main supervisor: Rolf Vegar Olsen

Co-supervisor: Björn Andersson

I also organize writing seminars for PhD candidates at the Faculty of Educational Science and co-organize the Oslo UseR! group.

Main project 

Vertical scaling of the Norwegian National Numeracy Tests (A scale for numeracy).
