    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Polynomial convexity; Positive currents; Jensen measures; Mathematical reasoning; assessment; university level; Subject didactics; Ämnesdidaktik;

    Sammanfattning : Avhandlingen består av två ganska olika delar som ändå har en del gemensamt. Del A är baserad på två artiklar i matematik och del B är baserad på två matematikdidaktiska artiklar. De matematiska artiklarna utgår från ett begrepp som heter polynomkonvexitet. LÄS MER

  4. 3. To explore and verify in mathematics

    Författare :Tomas Bergqvist; Hans Wallin; Johan Lithner; Morten Blomhøj; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Explorations; mathematical reasoning; empirical investigations; graphing calculators; conjectures.; Subject didactics; Ämnesdidaktik; MATHEMATICS; MATEMATIK; didactics of mathematics; matematikdidaktik;

    Sammanfattning : This dissertation consists of four articles and a summary. The main focus of the studies is students' explorations in upper secondary school mathematics. In the first study the central research question was to find out if the students could learn something difficult by using the graphing calculator. LÄS MER

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

    Författare :Anneli Dyrvold; Magnus Österholm; Ewa Bergqvist; Johan Lithner; Candia Morgan; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Prognostic Biomarkers and Target Proteins for Treatment of High-grade Gliomas

    Författare :Linda Sooman; Simon Ekman; Johan Lennartsson; Joachim Gullbo; Michael Bergqvist; Erik Blomquist; Stefan Bergström; Beatrice Melin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; High-grade glioma; prognostic biomarkers; combination chemotherapy; DNA methylation; FGF2; p38 MAPK; PTPN6; camptothecin; imatinib; vandetanib; EGFR; RAC1; Notch; Medical Science; Medicinsk vetenskap; Oncology; Onkologi;

    Sammanfattning : The survival for high-grade glioma patients is poor and the treatment may cause severe side effects. A common obstacle in the treatment is chemoresistance. To improve the quality of life and prolong survival for these patients prognostic biomarkers and new approaches for chemotherapy are needed. LÄS MER
