Academic interests
My research focuses the development of educational scales, primarily within the field of mathematics education.
Substantive Focus:
- Mathematics didactics
- Numeracy
- Norwegian context
Methodological Focus:
- Test-linking and vertical scaling
- Multidimensional Item Response Theory (MIRT)
- Differential Item Functioning (DIF)
My current work is under the 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
In addition, I co-organize the Oslo UseR! group.
