My PhD project addresses the content side in the science assessment of the large-scale study Trends in International Mathematics and Science Study (TIMSS). Most educational research has largely taken the achievement scores as a given, and used e.g. "science achivement" as measured in standardized assessments as outcome variable in correlational studies. In contrast to looking (merely) at the student and class-side of the item response equation, my project looks at what characteristics of the items can explain why some content is more difficult than others. Key concepts in this research are opportunity to learn, curriculum alignment, and within-domain characteristics, and topic difficulty. Key methods for exploring these issues include explanatory item response models (see e.g. de Boeck and Wilson, 2004).
