Henrik Galligani Ræder

Academic interests
My main research focuses is on the development of educational scales within the field of mathematics education.
Substantive Focus:
- Mathematics didactics
- Numeracy
- Norwegian context
- National assessment systems
- Educational equity
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.
Main project
Vertical scaling of the Norwegian National Numeracy Tests (A scale for numeracy).
