1. Green Chemistry in Chemical Education and Synthetic Applications of Sulfinamides
Sammanfattning : The preparation of chiral molecules, i.e. compounds that are not identical to their mirror image, is of great interest in the field of organic chemistry. LÄS MER
2. Charged Polymers: From DNA to Polyampholytes
Sammanfattning : Three main themes are outlined in this thesis: Polyelectrolytes/DNA : In a living cell, DNA molecules have a compact conformation in order to fit in, while in a test tube they will take on an expanded cylindrical shape, due to the negative phosphate groups along the DNA molecule. With the help of computer simulations it has been shown that like-charged monomers of a poly- electrolyte can attract each other if the counterions are taken into account. LÄS MER
3. När läroplan och tradition möts : Om lärarfortbildning och undersökande aktiviteters syfte inom den laborativa NO-undervisningen i grundskolans senare del
Sammanfattning : The Swedish curricula for compulsory school science emphasize laboratory inquiry-based science teaching (IBST) to develop pupils’ critical thinking. In contrast, several studies indicate that teachers within the Swedish teaching tradition almost solely emphasize laboratory work as a way to gain students understanding of traditional science content.

4. Topsar och cellmembran : Kroppens näringsupptag i undervisning och elevtexter på mellanstadiet
Sammanfattning : I avhandlingen studeras mellanstadieelevers meningsskapande kring näringsupptag. Avhandlingens artiklar baseras på två datainsamlingar. I den första studeras skriftliga svar på ett nationellt prov i biologi. I den andra studeras klassrumsundervisning i två skolor med en animation om näringsupptag som kontext. LÄS MER
5. Att ta ställning : Gymnasieelevers argumentation och beslutsfattande om sociovetenskapliga dilemman
Sammanfattning : This thesis aims to explore students’ argumentation and decision-making relating to authentic socioscientific issues (SSI). The ability to make informed decisions about socio scientific issues has been recognized to be an important element in science education to achieve the goal of scientific literacy. LÄS MER
