    Sammanfattning : In this study the teaching of mathematics has been developed in relation to rational numbers and towards a learning activity. At the same time topic-specific mediated tools have been studied. The iterative model for learning study has been used as research approach. LÄS MER

  5. 4. Mathematical Reasoning in Physics Tests : Requirements, Relations, Dependence

    Författare :Helena Johansson; Mats Andersson; Jesper Boesen; Kerstin Pettersson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematical reasoning; imitative reasoning; creative mathematical reasoning; physics tests; physics tasks; upper secondary school; Mantel-Haenszel procedure; Mathematical reasoning; imitative reasoning; creative mathematical reasoning; physics tests; physics tasks; upper secondary school; Mantel-Haenszel procedure.; Mantel-Haenszel procedure;

    Sammanfattning : By analysing and expanding upon mathematical reasoning requirements in physics tests, this licentiate thesis aims to contribute to the research studying how students’ knowledge in mathematics influence their learning of physics. A sample of physics tests from the Swedish National Test Bank in Physics was used as data, together with information of upper secondary students’ scores and grades on the tests. LÄS MER

  7. 5. Genetics and Labor Pain Behavior

    Författare :Fatimah Dabo Pettersson; Helena Åkerud; Inger Sundström Poromaa; Fred Nyberg; Pelle Lindqvist; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anxiety; beta-endorphin; depressed mood; GCH1; labor analgesia; labor pain; OPRM1; SNP; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Labor may perhaps be the most painful a woman might experience, although characterized by large inter-individual variability. The perceived pain during labor is the result of diverse factors, i.e. her previous pain experiences, the analgesia she receives and maybe also her genes. LÄS MER
