Gripe for å begripe matematikk

Abstract

Sammendrag Denne studien handler om hvordan 10.trinns elever tar i bruk konkreter og argumenterer når de løser problemløsningsoppgaver i et tenkendeklasserom. Studien belyser ulike karakteristikker i bruk av konkreter og argumentasjon hos ungdomsskole elever. Målet med studie er å si noe om hvordan konkrete hjelpemidler kan bidra inn i elevers argumentasjonsprosesser, noe som potensielt igjen kan bidra til at elevene får en dypere matematikkforståelse. Studien baserer seg på en kvalitativ forskningsmetode, hvor vi har fulgt en 10. klasseelevers matematikkundervisning gjennom tre undervisningsøkter. I disse undervisningsøktene har elevene arbeidet med ulike typer problemløsningsoppgaver. Datamateriale er samlet inn gjennom observasjon i form av videoopptak av to varierte elevgrupper. Videre er datamateriale analysert gjennom en induktiv tilnærming. Funnene i denne studien indikerer at typiske karakteristikker i elevenes bruk av konkreter og argumentasjon er: - Konkreter blir brukt til å formidle tankeprosess - Elevene bruker konkreter til å avkrefte eller argumentere for matematiske formler - Konkretene fungerer som et medierende redskap som formidler matematikk - Konkreter fungerer som støttemiddel i overgang til skriftlige løsninger
