Teachers reflections on addition strategies : An interview study on a specific addition task (English)
Abstract [sv]

Syftet med denna studie är att identifiera lärares reflektioner om en specifik uppgift om olika additionsstrategier som har genomförts i en matematiklektion i Shanghai. Den frågeställning som studien syftar att besvara är:

·         Vad karaktäriserar lärarnas reflektioner?

Studien är genomförd med kvalitativa intervjuer som metod och fyra lärare som undervisar i matematik har intervjuats. Lärarna som intervjuats har olika undervisningserfarenheter med avseende att bredda studiens urval. För att fånga och fokusera på lärarnas reflektioner har det teoretiska ramverket six-lens framework (SLF) använts som inspiration till intervjufrågorna. Ramverket består av olika linser, det vill säga olika aspekter av matematikundervisningen. 

I resultatet anser lärarna vikten av att elever behöver behärska flera olika strategier. Detta för att elever ska ha möjlighet att utveckla taluppfattning och nå målen i matematik. Det framgår även att tals del-helhetsrelationer är en viktig del inom grundläggande taluppfattning för att elever ska utveckla strategier. Vidare framgår det i resultatet att det är effektivt att lyfta flera strategier tidigt i undervisningen samt jämföra likheter och skillnader mellan dessa. 

Abstract [en]

The purpose of this study is to identify teachers' reflections on a specific task about different addition strategies that have been implemented in a mathematics lesson in Shanghai.

The question that the study aims to answer is:

• What characterizes teachers' reflections? 

The study was conducted with qualitative interviews as a method and four teachers who teach mathematics were interviewed. The teachers who have been interviewed have different teaching experiences with regard to broaden the study selection. To capture and focus on teachers' reflections, the theoretical framework six-lens framework (SLF) has been used as inspiration for the interview questions. The framework consists of different lenses, which are different aspects of mathematics teaching. 

The results shows that students need to know several different strategies because they should have the opportunity to develop knowledge of number sens and achieve the goals in mathematics. It is also clear that part-whole relationships of numbers are basic knowledge for students to develop strategies. Furthermore, it appears effective to teach multiple strategies early in the teaching and compare similarities and differences between these.
