1. 6. Defining Integrated Science Education and Putting It to Test

   Författare :Maria Åström; Karl-Göran Karlsson; Lars Ove Dahlgren; Ulf P. Lundgren; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Science education; international studies; PISA; curriculum integration; Subject didactics; Ämnesdidaktik; didactics of natural science;

   Sammanfattning : The thesis is made up by four studies, on the comprehensive theme of integrated and subjectspecific science education in Swedish compulsory school. A literature study on the matter is followed by an expert survey, then a case study and ending with two analyses of students’ science results from PISA 2003 and PISA 2006. LÄS MER

3. 7. Design of Functional Polymeric Nanoparticles for Biomedical Applications

   Författare :Heba Asem; Eva Malmström; Tim Bowden; KTH; []

   Sammanfattning : Most of the devastating diseases such as cancer are relatively incurable and have high risks of relapse. Therefore, persistent endeavors have been devoted to improve patient survival rate and quality of life. LÄS MER

4. 8. Statistical modeling in international large-scale assessments

   Författare :Inga Laukaityte; Marie Wiberg; Kenny Bränberg; Ewa Rolfsman; Bernard Veldkamp; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multilevel model; plausible values; sampling weights; missing information; multiple imputation; non-monotone missing pattern; TIMSS; PISA; Statistics; statistik; pedagogik; Education;

   Sammanfattning : This thesis contributes to the area of research based on large-scale educational assessments, focusing on the application of multilevel models. The role of sampling weights, plausible values (response variable imputed multiple times) and imputation methods are demonstrated by simulations and applications to TIMSS (Trends in International Mathematics and Science Study) and PISA (Programme for International Student Assessment) data.

5. 9. Nanolatexes: a versatile toolbox for cellulose modification

   Författare :Alexandros Efraim Alexakis; Eva Malmström; Justin Zoppe; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanolatexes; RAFT; PISA; adsorption; cellulose; modification; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Cellulosic materials are widely used in our everyday lives, ranging from paperand packaging to biomedical applications. However, in most applications, cellulose must coexist with hydrophobic polymers which can be challenging due to its hydrophilic character. This has encouraged the exploration of chemical and physical modifications of cellulose. LÄS MER

7. 10. Exploring socioeconomic inequality in educational opportunity and outcomes in Sweden and beyond

   Författare :Victoria Rolfe; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; inequality; socioeconomic status; opportunity to learn; student achievement; teacher characteristics; TIMSS; PISA;

   Sammanfattning : This doctoral thesis aims to explore Sweden’s achievement gap in international assessment and how this may have developed in the context of a network of educational inequalities. Theoretically grounded in the Model of Potential Educational Experiences (Schmidt, Raizen, Britton, Bianchi, & Wolfe, 1997), the thesis investigates how the relationship between the intended and attained curriculum is moderated by actions at the classroom level.
