2. Students’ participation in the realization of school science activities
Sammanfattning : I denna avhandling visar jag hur elever och lärare genomför NO-verksamhet i grundskolan. Avhandlingen illustrerar hur elevers frågor och uttryckta erfarenheter blir en del av ett etablerat ämnesinnehåll. LÄS MER
3. Measurement and modelling of unbalanced magnetic pull in hydropower generators
Sammanfattning : Hydropower research is often perceived to be an old and exhausted field of study but with ageing equipment and the need for more intermittent operation caused by an increased share of other renewable energy sources new challenges lie ahead.The main focus of this dissertation are the electromagnetic forces resulting from nonuniform air gap flux, whether it be caused by rotor eccentricity or a faulty field winding.

4. QED and collective effects in vacuum and plasmas
Sammanfattning : The theory of quantum electrodynamics (QED) was born out of an attempt to merge Einsteins theory of special relativity and quantum mechanics. Einsteins energy/mass equivalence together with Heisenberg's uncertainty principle allows for particle pairs to be spontaneously created and annihilated in vacuum. LÄS MER
5. Exploring the complexities of integrating socioscientific issues in science teaching
Sammanfattning : Socioscientific issues, SSI, can briefly be described as societal issues in which science plays a role. Dealing with SSI in science education is a means to prepare and empower students for active and responsible participation in a complex, democratic society. LÄS MER
