The Graduate School teaches, methodological basics and specific procedures including, “Methodological Foundations of Observational Research Procedures”, “Data Collection in the Classroom” (with and without video recordings) and “Data Analysis Procedures” (qualitative coding, sequence analytical procedures, rating procedures). This is partly done in cooperation with the methodological centers of the Universities of Kassel and Halle. Methodological (and scientific-theoretical) grounding also concerns the entire collegial group as a way to encourage mutual understanding and discourse across different research paradigms. More specific methodological procedures and problems can then also be worked out in smaller groups by those who apply these procedures in their projects (reconstructive procedures such as conversation analysis, documentary method, objective hermeneutics, or statistical procedures such as multivariate statistics, structural equation models, Markov chains, etc.).
