  1. 1. Students' understandings of multiplication

    Författare :Kerstin Larsson; Kerstin Pettersson; Paul Andrews; Lieven Verschaffel; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Multiplication; students’ understanding; connections; multiplicative reasoning; models for multiplication; calculations; arithmetical properties; Mathematics Education; matematikämnets didaktik;

    Sammanfattning : Multiplicative reasoning permeates many mathematical topics, for example fractions and functions. Hence there is consensus on the importance of acquiring multiplicative reasoning. LÄS MER

  2. 2. Grafisk och algebraisk representation : Gymnasieelevers förståelse av linjära funktioner

    Författare :Annika Pettersson; Igor Gachkov; Kerstin Pettersson; Lovisa Sumpter; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; mathematics education; linear function; graphic representation; scale; concept image; Matematik; Mathematics;

    Sammanfattning : This thesis concerns upper secondary students’ understanding of algebraic and graphic representation of linear functions. Components of the students’ concept images, so-called ‘concept elements’, were studied as a way to capture their understanding. LÄS MER

  3. 3. Algoritmiska, intuitiva och formella aspekter av matematiken i dynamiskt samspel : en studie av hur studenter nyttjar sina begreppsuppfattningar inom matematisk analys

    Författare :Kerstin Pettersson; Högskolan i Skövde; Gothenburg University; Göteborgs universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Algorithmic context; Calculus; Conceptual understanding; Contextualisation; Higher education; Intentional analysis; Learning potentiality; Procedural knowledge; Subject didactics; Ämnesdidaktik; Humanities and Social sciences; Humaniora-samhällsvetenskap;

    Sammanfattning : Focusing on the potentiality of students’ ways of treating a mathematicalmaterial this thesis aims to investigate how students use their conceptualunderstanding when working with mathematical tasks in calculus. Two casestudies were carried out to explore students’ understanding of thresholdconcepts. LÄS MER

  4. 4. Samspel mellan intuitiva idéer och formella bevis : en fallstudie av universitetsstudenters arbete med en analysuppgift

    Författare :Kerstin Pettersson; Högskolan i Skövde; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; MATHEMATICS; MATEMATIK; MATHEMATICS; MATEMATIK; MATHEMATICS; MATEMATIK;

    Sammanfattning : The aim of this study is to illuminate the interplay between intuitive ideas and formal justification. In a perspective where we focus on the students’ competences we describe the interaction between intuitive ideas and formal structures, as they appear especially in relation to concept definitions and formal proofs.
