  2. 2. Teaching for the learning of additive part-whole relations : The power of variation and connections

    Författare :Anna-Lena Ekdahl; Ulla Runesson Kempe; Hamsa Venkat; Camilla Björklund; Christiane Benz; Högskolan i Jönköping; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; variation; variation theory; connections in teaching; making connections; early numbers; teaching and learning additive relations; part-whole relation; part-whole relations of numbers; intervention study;

    Sammanfattning : In this thesis, results from four empirical studies and a re-analysis are synthesized with what can constitute a structural approach to teaching and learning additive part-whole relations among learners aged four to eight years. In line with a structural approach to additive relations, the relations of parts and whole are in focus from the outset and are seen as the basis for addition and subtraction (Davydov 1982; Neuman, 1987).

  3. 3. Variation och invarians i Maria Montessoris sinnestränande materiel

    Författare :Kerstin Signert; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Montessori; Montessori pedagogy; sensorial education; variation theory; variation; invariance; learning;

    Sammanfattning : The purpose of this study was to analyse the Montessori pedagogy with the objective to theoretically describe and explain the Montessori pedagogical method. The aim has been to find an answer to what still makes the Montessori pedagogy, after more than one hundred years, successfully spread to schools all over the world. LÄS MER

  4. 4. Population-level consequences of variation

    Författare :Lena Wennersten; Anders Forsman; Olof Leimar; Deepa Agashe; Linnéuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; colour polymorphism; diversity; establishment success; evolutionary changes; population-level consequences; predation risk; Tetrix subulata; variation; Evolutionary Biology; Evolutionsbiologi;

    Sammanfattning : Consequences of within population variation have recently attracted an increased interest in evolutionary ecology research. Theoretical models suggest important population-level consequences, but many of these predictions still remain to be tested. LÄS MER

  5. 5. Metabolic variation in autoimmune diseases

    Författare :Rasmus Kirkegaard Madsen; Johan Trygg; Thomas Moritz; Torbjörn Lundstedt; Matej Oresic; Umeå universitet; []
    Nyckelord :Rheumatoid Arthritis; Diabetes Mellitus type 1; Metabolic Profiling; Metabolomics; Chemometrics; Multivariate Data Analysis; Mass Spectrometry; biologisk kemi; biological chemistry;

    Sammanfattning : The human being and other animals contain immensely complex biochemical processes that govern their function on a cellular level. It is estimated that several thousand small molecules (metabolites) are produced by various biochemical pathways in humans. LÄS MER
