Bakgrunn og aktiviteter

Heidi Strømskag (1965) har vært førsteamanuensis ved Institutt for matematiske fag siden 2015. Hun er cand.scient. i matematikk fra NTNU, og PhD i matematikkdidaktikk fra Universitetet i Agder. Hennes forskningsområder er for tiden: didaktiske situasjoner og funksjonen til og utviklingen av et adidaktisk miljø; oppgavedesign i matematikk; og undervisning og læring av algebraisk tenkning.

Strømskag deltar i intervensjonsprosjektet LaUDiM (Language Use and Development in the Mathematics Classroom), der hun anvender teorien for didaktiske situasjoner for å studere og utvikle læreres matematikkundervisning.
