1. Conceptual metaphors in learning and teaching entropy : adopting a cognitive semantic approach in science education research
Sammanfattning : Over the last 20 years there has been an extensive amount of research on science learning conducted from a “knowledge-in-pieces” or “resources” perspective. One of the main goals of that research has been to identify and characterize available cognitive knowledge resources that can be productive components of scientific understanding. LÄS MER
2. Reasoning with thermal cameras : Framing and meaning-making in naturalistic settings in higher education
Sammanfattning : In this Licentiate thesis, framed by the Resources framework and Social semiotics, I explore how students and instructors, investigating thermal phenomena with IR cameras, come to conceptually and epistemologically frame the naturalistic settings they participate in. Additionally, I look at how they productively employ resources , what barriers they encounter while reasoning about the thermal phenomena and how the semiotic resources of the IR camera relate to the framing and resources employed in their investigations.

3. On Subscale Flight Testing : Applications in Aircraft Conceptual Design
Sammanfattning : Downscaled physical models, also referred to as subscale models, have played an essential role in the investigation of the complex physics of flight until the recent disruption of numerical simulation. Despite the fact that improvements in computational methods are slowly pushing experimental techniques towards a secondary role as verification or calibration tools, real-world testing of physical prototypes still provides an unmatched confidence.

4. Energi som kunskapsområde : Om praktik och diskurser i skolan
Sammanfattning : This study concerns how energy is treated as an area of knowledge in the Swedish school. Energy is encountered in traditional subjects such as history, physics and social studies. Energy also has another entry due to its constant relevance in the world outside school, thereby obligating school to address and discuss energy within its curriculum. LÄS MER
5. Experimental Studies of Primary Break-up of Diesel Engine Fuel Injector Sprays
Sammanfattning : This thesis will focus on experimental studies of primary breakup of pressure-atomized sprays. The industrial application that this thesis will address is fuel sprays in modern Diesel engines, and so the focus will be sprays emitting into relatively slow-moving, high pressure, high-temperature gases.
