Felix Schreiber is a research assistant at the Institute of Education. He is currently responsible for supervising portfolio work in teacher education in Tübingen. As a member of the work group ›research on teachers and teacher education with a special emphasis on subject didactics‹ (Prof. Cramer) his research focuses on the project ›systematization of research on teacher education (SYSTEM)‹. The aim of the project is to gain a criterium-led overview of the key discourse elements in the scientific discourse on teacher education through systematic content analysis. In his doctoral thesis he systematically develops dimensions of “educational sciences” (Bildungswissenschaften) and “subject matter teaching and learning” (Fachdidaktik). At the same time, he attempts to methodically elaborate the method “systematic review” as systematizing content analysis of scientific discourse.
