1. Avdunstning och molekyler : en longitudinell studie av hur grundskoleelever utvecklar sina uppfattningar om avdunstningsfenomen
Sammanfattning : This thesis presents results from a longitudinal study of students in compulsory school. The project started in spring 1997 when the students were about six years old, and finished in spring 2006 when they left compulsory school. LÄS MER
2. Avdunstning och molekyler : en longitudinell studie av hur grundskoleelever utvecklar sina uppfattningar om avdunstningsfenomen
Sammanfattning : Denna avhandling presenterar resultat från en longitudinell studie i grundskolan. Projektet startade våren 1997 då eleverna var omkring sex år och avslutades våren 2006 då eleverna lämnade grundskolan. Ett mål med studien var att följa individuella elevers begreppsutveckling kring avdunstning under deras år i skolan. LÄS MER
3. Disinformative and Uncertain Data in Global Hydrology : Challenges for Modelling and Regionalisation
Sammanfattning : Water is essential for human well-being and healthy ecosystems, but population growth and changes in climate and land-use are putting increased stress on water resources in many regions. To ensure water security, knowledge about the spatiotemporal distribution of these resources is of great importance. LÄS MER
4. Med kroppen som illustration : Hur förskolebarn prat-skapar naturvetenskap med hjälp av multimodala och kroppsförankrade förklaringar
Sammanfattning : The aim of this thesis is to combine three research areas, namely preschool, science and illustrations, in order to examine (a) how modes are combined when references to the body are made or the body as such are used to explain scientific concepts and phenomena in preschool science education, and (b) how do the children handle, explore, discuss and talk science when approaching multimodally illustrated scientific contents in the studied activities. Four studies were conducted, all of which were built on empirically generated questions and were theoretically grounded in cultural-historical and multimodal perspectives. LÄS MER
5. Evaporation and Heat-flux Aggregation in Heterogeneous Boreal Landscapes
Sammanfattning : The boreal forests represent 8 % of all forested areas on the earth and have a significant role in the control of greenhouse gases and an impact on global climate change. The main objective of this thesis is to increase the understanding of how evaporation and heat-flux processes in the boreal forest zone are affecting the regional and global climate. LÄS MER
