Simultaniety between addition and subtraction : An interview study about teaching that show the relation between addition and subtraction (English)
Abstract [sv]

Syftet med denna studie är att ge en bild av undervisning som synliggör sambandet mellan addition och subtraktion. Elever har visat svårigheter med att använda sambandet mellan addition och subtraktion för att lösa olika aritmetiska problem. Samtidigt är det en viktig förutsättning för att utveckla effektiva lösningsstrategier. Studien är genomförd med inspiration från fenomenografi där kvalitativ intervju använts som metod. Fem lärare i årskurs 1–3 har intervjuats. Lärarna som har intervjuats har medverkat i två olika utvecklingsprojekt där de tillsammans med forskare fördjupat sig i addition och subtraktion. Resultatet visar på vikten av att tidigt synliggöra sambandet mellan addition och subtraktion samt uppdelningen av tal för att elever effektivt ska kunna lösa olika aritmetiska problem. Vidare framgår i resultatet att sambandet mellan addition och subtraktion kan synliggöras genom att arbeta med addition och subtraktion samtidigt, att undervisa om tals del-helhetsrelationer och genom medvetna val av konkret material och representationsformer av tal. 

Abstract [en]

The purpose of this study is to provide a comprehensive understanding and insights regarding teaching that show the relation between addition and subtraction. Students have shown difficulty in using the relation between addition and subtraction to solve arithmetic problems. At the same time, it is an important prerequisite for developing effective strategies. The study is inspired by phenomenography where qualitative interview was used as a method. Five teachers have been interviewed, which is operative in the first to third grade. The participating teachers have been participating in development projects where they were accompanied by researchers who deepened their knowledge within addition and subtraction. The study shows the importance to visually illustrate the connection between addition and subtraction in an early phase, as well as the separation of numbers so that students are able to solve arithmetic problems more efficiently. Furthermore, the result shows that the relation between addition and subtraction can be shown by working with addition and subtraction simultaneously, working with part-whole relations, and through smart choice of concrete material and representation of numbers.
