  5. 3. Difficult to read or difficult to solve? : The role of natural language and other semiotic resources in mathematics tasks

    Author : Anneli Dyrvold; Magnus Österholm; Ewa Bergqvist; Johan Lithner; Candia Morgan; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; multisemiotics; task text; difficulty; mathematical reading ability; matematikdidaktik; didactics of mathematics; Mathematics; Pedagogik; Linguistics;

    Abstract : When students solve mathematics tasks, the tasks are commonly given as written text, usually consisting of natural language, mathematical notation and different types of images. This is one reason why reading and interpreting such texts are important parts of being mathematically proficient, at least within the school context. READ MORE

  7. 5. Mathematics teachers' conceptions about equations

    Author : Iiris Attorps; Högskolan i Gävle; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; algebra; conception; equation; learning; mathematics teacher; Subject didactics; Ämnesdidaktik; MATHEMATICS; MATEMATIK;

    Abstract : The aim of this study is to describe and to clarify the mathematics teachers’ subject matter and pedagogical content conceptions about equations. As the basis of these conceptions, the teachers’ experiences of the concept learning of equations from their own school time are described. READ MORE
