Lärande i bråk - transformationer mellan representationsformer ur ett socialsemiotiskt multimodalt perspektiv

Roos, Helena, Ebbelind, Andreas January 2011 (has links)
Denna studie presenterar ett preliminärt ramverk för analys av lärande i bråk inom ramen för transformationer mellan olika former av representationer. Ramverket används i en empirisk studie där åtta 10-åriga elever genomför uppgifter i bråk, som utvecklats för att utmana dem att reflektera över olika sätt att representera aspekter av begreppet bråk. Ramverket bygger på socialsemiotikens multimodala perspektiv. Analysen belyser hur ramverket hjälper till att strukturera förståelse för samspelet mellan representationer i inlärningen av bråk. Specifikt såg vi hur konkret fysiskt material och gester kompletterar symboliskt representation och talat språk i elevernas lösningar. / This study presents a tentative framework for the study of learning fractions in the context of transformations between different forms of representations. The framework is used in an empirical sample of how eight 10-year-old students express understanding of mathematics tasks, which were developed to challenge them to reflect on different ways to represent aspects of the concept of fractions. The framework is based on a social semiotic perspective of multimodality. The analysis discloses how the framework helps in structuring understanding of the interplay between representations in the learning of fractions. Specifically we saw how concrete physical material and gestures complemented the symbolic and spoken language in the students’ solution strategies of different tasks.
