Elevers strategier för att fortsätta avtagande kvadratiska talföljder

Abstract [sv]

Syftet med detta arbete är att studera strategier som elever använder för att fortsätta avtagande kvadratiska talföljder. Studien inriktar sig på årskurs 3 och 6. En kvantitativ enkätundersökning har genomförts där fyra olika uppgifter har besvarats av eleverna i de olika årskurserna. Vi fann att elever använde sig av samma sorts strategier i båda årskurserna, men att det skedde i olika stor utsträckning. Vår undersökning visar att strategin som innebär att att eleverna tittar på skillnaden mellan talen i en talföljd, är mer förekommande än andra i årskurs 3. I årskurs 6 fanns en större variation av två strategier. Dessa strategier var se skillnaden mellan talen, samt se skillnaden mellan skillnaden. Det fanns även skillnader i hur elever uttryckte de olika strategierna mellan årskurserna.

Abstract [en]

The aim of this paper is to explore the strategies students use when they continue decreasing, quadratic number sequences. The investigated grades are 3 and 6. The study was quantitative and a questionnaire survey was used. The questionnaire consisted of four different tasks. We found that students in both grades used the same strategies, but the distribution of the strategies were different. Our study shows that one strategy was more common than others in grade 3, and this strategy was looking for differences between the numbers. In grade 6 two strategies were more common than the others. These strategies were looking for differences and looking for differences between differences. We also found differences between the pupils way to express the different strategies.
