  1. 16. Drawing Science : Visual Content Formation in Young Students’ Multimodal Science Compositions

    Författare :Elin Westlund; Charlotte Engblom; Caroline Liberg; Anna-Malin Karlsson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; content representation; early school years; science education; multimodal text-making; visual literacy; Curriculum Studies; Didaktik;

    Sammanfattning : This thesis explores visual formation of science content in young students’ multimodal text-image compositions. In doing so, it also contributes a metalanguage for visual meaning-making about science content in the early school years. LÄS MER

  3. 17. The wild male mink as a sentinel for endocrine-disrupting chemicals and reproductive toxicity

    Författare :Sara Persson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Increasing evidence indicates that pollutants may affect the hormone system of humans and wildlife. These endocrine-disrupting chemicals are related to an increased risk of a variety of diseases and disorders, including adverse effects on the reproductive system. LÄS MER

  4. 18. Taste for Science : How can teaching make a difference for students’ interest in science?

    Författare :Per Anderhag; Per-Olof Wickman; Karim Mikael Hamza; Heidi Carlone; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; interest in science; taste for science; norms; values; aesthetics; secondary school; home background; teaching; learning; equity; pragmatism; Bourdieu; naturvetenskapsämnenas didaktik; Science Education;

    Sammanfattning : The objective of the thesis is to describe and analyse aspects of home background and teaching that may be important for students’ capability and will to participate in science. The purpose is to make explicit how teaching can support students in developing an interest in science and so counter-balance the restricted opportunities some students may have due to upbringing.

  5. 19. Improving our understanding of carbon cycling in agroecosystems by studying δ¹³C signatures in soil carbon stocks and fluxes : results from a Swedish long-term field experiment

    Författare :Lorenzo Menichetti; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Soil carbon (C) storage has gained much attention in the past decade due to its potentially huge impact on climate change mechanisms. Particular focus has been paid to possible feedback mechanisms, whether soil can be considered a sink or source of C and how soils can be managed in order to mitigate climate change. LÄS MER

  7. 20. Earthworm and arbuscular mycorrhizal communities in agricultural soils : management of key soil organisms for sustainable agriculture

    Författare :Kaisa Torppa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Intensive agriculture is detrimental to soil biodiversity and functioning. Promoting communities of key soil organisms, such as earthworms and arbuscular mycorrhizal (AM) fungi, may help improve agricultural sustainability by replacing inputs with ecosystem services. LÄS MER
