Textbaserade uppgifter och deras representationsformer.- En läromedelsanalys på två tryckta läroböcker för årskurs nio i grundskolan.
Sammanfattning: Research shows that pupils experience difficulties with the word problems in their mathematical textbooks. The forms of representations are made visible through the word problems and are vital elements considering the pupils’ understanding of the basic idea of important concepts. The purpose of this study is to provide knowledge about how word problems in mathematical textbooks and their forms of representations can be used by pupils’ as a linguistic tool. Moreover, this research has used a quantitative content analysis where two different textbooks, their word problems and the forms of representations have been analyzed and quantified. The result shows that almost every word problem uses the representation of symbols. Furthermore, the majority of the word problems use the representation of real situations while the representation of picture is less evident. The result also shows that mathematical textbooks can be seen as a linguistic tool for the pupils since mathematical concepts often are expressed through different forms of representation. As a suggestion, teachers’ can complement their mathematical textbooks with external assignments based on the representations of picture situations to develop the pupils’ understanding.
