Introduksjon av algebra i matematikkbøker for ungdomstrinnet i Norge

Authors

Tom Rune Kongelf

Abstract

I denne artikkelen presenterer vi funnene fra en analyse av introduksjonskapitlet i algebra i seks ulike lærebøker. Introduksjonen til bokstaver som symbol for variable størrelser varierer med hensyn til klassetrinn, mengde og kontekst. Gjennom en induktiv kvalitativ innholdsanalyse karakteriserer vi mangelfulle sider ved kapitlene. Hovedfunnene er at variabelaspektet ikke kommer tydelig frem, og at en i liten grad benytter mulighetene til å bygge videre på tallære. I tillegg inneholder lærebøkene feilaktige formuleringer, illustrasjoner og matematiske resonnement, som legger forholdene til rette for utvikling av misoppfatninger.
