Abstract

Syftet med denna artikel är att beskriva och diskutera vilka funktioner lärandemodeller kan ha för att främja yngre elevers kollektiva diskussioner om algebraiska uttryck. Artikeln bygger på data från ett designforskningsprojekt baserat på Davydovs principer för lärandeverksamhet, bestående av videofilmade forskningslektioner i årskurs 1 och 5. Analysen fokuserar på vad som skapar förutsättningar för helklassdiskussioner om algebraiska uttryck, hur de drivs framåt och kvalificeras samt vilka funktioner lärandemodeller kan ha för elevernas utforskande av matematiska strukturer och relationer i algebraiska uttryck. Resultatet indikerar att lärandemodeller som medierande redskap gör det möjligt för eleverna att föra kreativa och reflekterande diskussioner om algebraiska uttryck och deras komponenter.
