Henrik Galligani Ræder
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
In addition, I co-organize the Oslo UseR! group.
Main project
Vertical scaling of the Norwegian National Numeracy Tests (A scale for numeracy).
