  1. 11. Approaching Mathematical Discourse : Two analytical frameworks and their relation to problem solving interactions

    Författare :Andreas Ryve; Kimmo Eriksson; Inger Wistedt; Anna Sfard; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Didactics of Mathematics; Mathematics Education; Analytical approaches; Communication; Concept maps; Contextualization; Discourse; Engineering students; Higher Education; Intentional analysis; Methodological framworks; Problem solving; Prospective teachers; Student teachers; Teacher education; Theoretical frameworks; MATHEMATICS; MATEMATIK; Matematik tillämpad matematik;

    Sammanfattning : The driving force of conducting the two studies presented in this thesis is to examine ways that conceptual understanding and problem solving could be part of mathematics teaching, and through that, part of students' mathematical knowledge. The specific aims of the thesis are: 1) to characterize the classroom discourse of two, apparently similar, problem solving courses in teacher education and 2) to discuss the possibilities of developing two analytical approaches - the communicational approach to cognition and the dialogical approach - used for studying mathematical discourse.

  5. 14. Matematikproblem i skolan : för att skapa tillfällen till lärande

    Författare :Eva Taflin; Johan Lithner; Ole Björkqvist; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; problem-solving; rich problem; teacher; instruction; learning; mathematical ideas; occasions; MATHEMATICS; MATEMATIK;

    Sammanfattning : The general purpose of this dissertation is to define and explore what mathematical problem solving entails. Seven criteria for rich problems will also be formulated. Rich problems are defined as problems which are especially constructed for mathematics education in a school context. LÄS MER

  7. 15. Mathematical Reasoning : In physics and real-life context

    Författare :Helena Johansson; Mats Andersson; Jesper Boesen; Morten Blomhøj; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Creative mathematical reasoning; Descriptive statistics; Differential item functioning; Figurative context; Imitative reasoning; Mathematical Reasoning Requirements; Mathematics tasks; National tests; Physics tasks; Real-life context; T-test; Upper secondary school; Creative mathematical reasoning; Descriptive statistics; Differential item functioning; Figurative context; Imitative reasoning; Mathematical Reasoning Requirements; Mathematics tasks; National tests; Physics tasks; Real-life context; T-test; Upper secondary school;

    Sammanfattning : This thesis is a compilation of four papers in which mathematical reasoning is examined in various contexts, in which mathematics is an integral part. It is known from previous studies that a focus on rote learning and procedural mathematical reasoning hamper students’ learning of mathematics. LÄS MER
