    Abstract : Half the world’s river volume is affected by flow alterations and/or fragmentation, a figure that is likely to increase with the current global surge in hydropower development. At the same time, freshwater biodiversity is in rapid decline. READ MORE

  2. 2. 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 : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; HUMANITIES; HUMANIORA; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; mathematics education; multisemiotics; task text; difficulty; mathematical reading ability; didactics of mathematics; matematikdidaktik; word; image; symbol; mathematical notation; cohesion; Mathematics; Matematik; Pedagogik; Education; Linguistics; Lingvistik;

    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

  3. 3. Contributing to develop contributions : - a metaphor for teaching in the reform mathematics classroom

    Author : Andreas Eckert; Per Nilsson; Barbara Jaworski; Linnéuniversitetet; []

    Abstract : This thesis aims at contributing to the theoretical research discourse on teaching mathematics. More precise, to explore a teacher’s role and actions while negotiating meaning of mathematical objects in discursive transformative practices in mathematics. READ MORE

  4. 4. Mathematics teachers' conceptions about equations

    Author : Iiris Attorps; Högskolan i Gävle; []

    Abstract : The existence of new technologies, implemented in efficient platforms and workflows has made massive genotyping available to all fields of biology and medicine. Genetic analyses are no longer dominated by experimental work in laboratories, but rather the interpretation of the resulting data. READ MORE
