  1. 1. “Count on me!” : Mathematical development, developmental dyscalculia and computer-based intervention

    Författare :Linda Olsson; Ulf Träff; Joakim Samuelsson; Lisa Thorell; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematical development; symbolic number processing; Approximate number system; developmental dyscalculia; computer-based intervention; matematisk utveckling; symboliskt nummerprocessande; Approximativa nummersystemet; dyskalkyli; datorbaserad intervention;

    Sammanfattning : A “sense” of number can be found across species, yet only humans supplement it with exact and symbolic number, such as number words and digits. However, what abilities leads to successful or unsuccessful arithmetic proficiency is still debated. LÄS MER

  3. 2. Magnitude Processing in Developmental Dyscalculia : A Heterogeneous Learning Disability with Different Cognitive Profiles

    Författare :Kenny Skagerlund; Ulf Träff; Thomas Karlsson; Bert De Smedt; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Developmental Dyscalculia; mathematical learning disabilities; number sense; Dyskalkyli; matematiksvårigheter; antalsuppfattning;

    Sammanfattning : Developmental dyscalculia (DD) is a learning disability that is characterized by severe difficulties with acquiring age-appropriate mathematical skills that cannot be attributed to insufficient education, language skills, or motivation. The prevalence rate is estimated at 3-6%, meaning that a substantial portion of the population struggles to learn mathematics to such a large degree that it affects overall well-being and academic prospects.

  4. 3. Tid till förfogande : Förändrad användning och fördelning av undervisningstid i grundskolans senare år?

    Författare :Mikaela Nyroos; Lisbeth Lundahl; Anders Lidström; Mikael Alexandersson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; School autonomy; time allocation; time use; pupil influence; pupil individualisation; teacher work; change.; Pedgogical work; Pedagogiskt arbete;

    Sammanfattning : The Swedish education system has undergone decentralisation and deregulation since the late 1970s. The 1999 parliamentary resolution for a 5-year experiment of increased school autonomy in time allocation, was a late step in this development. LÄS MER

  5. 4. Recent changes in land use and productivity in agro-pastoral Inner Mongolia, China

    Författare :Sara Brogaard; LUCSUS; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geomorphology; Physical geography; China; Inner Mongolia; remote sensing; LUE model; primary production; GPP; yield variability; land degradation; farmers’ perception; productivity; Land use; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Sammanfattning : This study challenges the prevailing assumption that the expansion of cultivated land areas and increasing number of livestock in the agro-pastoral regions of northern China have aggravated the process of land degradation since the start of the rural reforms in 1978. Land-use and productivity trends in the Inner Mongolia Autonomous Region (IMAR), with special attention to the Keerqin steppe region, have been analysed. LÄS MER

  7. 5. The HCCI Fuel Number - Measuring and Describing Auto-ignition for HCCI Combustion Engines

    Författare :Ida Truedsson; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel; Combustion Engines; HCCI; Auto-ignition;

    Sammanfattning : HCCI is an advanced combustion concept, using premixed fuel and air with a diluted charge. This is thermodynamically favorable, leading to high efficiency and therefore lower CO2 emissions. LÄS MER
