    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

  4. 3. Progression of algebraic discourse in school years 2 to 8

    Författare :Maria Kenneman; Ewa Bergqvist; Magnus Österholm; Umeå universitet; []

    Sammanfattning : In contemporary educational settings algebra is considered to be of vital importance for student's continuation to more advanced studies in mathematics, thereby affecting their chances for future education and employment. However, a substantial number of students do not benefit from the algebra presently taught in schools and fail to use algebraic reasoning. LÄS MER

  5. 4. Iatrogenic Vascular Injuries

    Författare :Håkan Rudström; Martin Björck; David Bergqvist; Carl Magnus Wahlgren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vascular injuries; vascular surgery; vascular trauma; injury; medical error; patient safety; postoperative death; postoperative mortality; patient insurance; varicose veins; Kirurgi; Surgery;

    Sammanfattning : Iatrogenic vascular injuries (IVIs) and injuries associated with vascular surgery can cause severe morbidity and death. The aims of this thesis were to study those injuries in the Swedish vascular registry (Swedvasc), the Swedish medical injury insurance where insurance claims are registered, the Population and Cause of death registries, and in patient records, in order to explore preventive strategies.

    Sammanfattning : Practicing mathematics is not possible without the use of language. To communicate mathematical content, not only words in natural language are used but also non-verbal forms of communication such as mathematical symbols, graphs, and diagrams. All these forms of communication can be seen as part of the language used when doing mathematics. LÄS MER
