Bakgrunn og aktiviteter

Heidi Strømskag 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 relasjonen mellom adidaktiske miljø og matematisk kunnskap; oppgavedesign i matematikk; og undervisning og læring av algebraisk tenkning.

Strømskag er Norges representant til ICMI (International Commission on Mathematical Instruction).

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