Academic interests
My research focuses on the Norwegian national assessments, vertical scaling and the numeracy proficiency of Norwegian students. 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
Main project
As part of the overarching project, my PhD-project, A scale for numeracy, is aimed at connecting the Norwegian national assessments in numeracy.
Education
MA, Didactics of Physics and Mathematics, University of Oslo, Norway
Background
My master thesis focused on what mathematical activities were necessary to solve physics-items in TIMSS Advanced 2015. Additionally, it investigated how Norwegian students performed on items where different activities were assumed necessary. Parallel to my studies i worked as a research assistant in Relekvant.
