1. Learning Chemistry at the University level : Student attitudes, motivation, and design of the learning environment
Sammanfattning : The main purpose of the research this thesis is based upon was to study students’ attitudes towards learning chemistry at university level and their motivation from three perspectives. How can students’ attitudes towards learning chemistry be assessed? How can these attitudes be changed? How are learning situations experienced by students with different attitude positions? An attitude questionnaire, assessing views of knowledge, learning assessments, laboratory activities, and perceived roles of instructors and student, was used to estimate students’ attitude positions.

2. Models in chemistry education : A study of teaching and learning acids and bases in Swedish upper secondary schools
Sammanfattning : This thesis reports an investigation of how acid-base models are taught and understood in Swedish upper secondary school. The definition of the concepts of acids and bases has evolved from a phenomenological level to an abstract (particle) level. Several models of acids and bases are introduced in Swedish secondary school. LÄS MER
3. Den laborativa klassrumsverksamhetens interaktioner : En studie om vilket meningsskapande år 7-elever kan erbjudas i möten med den laborativa verksamhetens instruktioner, artefakter och språk inom elementär ellära, samt om lärares didaktiska handlingsmönster i dessa möten
Sammanfattning : This thesis studies students’ encounters with school science language games within the framework of laboratory classroom activities in Elementary Electricity. The focus is on students’ interaction with the teacher and with other students as well as with artefacts. LÄS MER
4. Analogical reasoning in science education : - connections to semantics and scientific modelling in thermodynamics
Sammanfattning : Analogiskt tänkande är en central kognitiv förmåga som vi använder i vardagslivet, såväl som i mer formella sammanhang, såsom i forskning och undervisning. Föreliggande avhandling behandlar hur analogier och analogiskt tänkande, uppmärksamhet på semantik och förståelse för vetenskaplig modellering kan användas för att hantera utmaningar i naturvetenskapsundervisningen, särskilt inom området termodynamik.

5. 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
