  5. 14. Betyget i matematik : Vad ger grundskolans matematikbetyg för information?

    Författare :Staffan Stenhag; Jonas Almqvist; Bo Johansson; Leif Östman; Astrid Pettersson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics; study achievement; grade; argument; compulsory school; reading comprehension; transfer of learning; Subject didactics; Ämnesdidaktik; Curriculum Studies; Didaktik;

    Sammanfattning : The aim of this study is to investigate what the grade in mathematics tells us about the pupil’s general academic success in other school subjects in Sweden’s compulsory school. What proficiency, except mathematical skills, does a high grade in mathematics indicate? First an inventory of the official arguments for school mathematics was conducted. LÄS MER
