In diesem mehrtägigen Methoden-Workshop erhiehlten die Teilnehmer einen Crahkurs für das Statistikprogramm R. Der Workshop wurde geleitet von Dr. Till Kaiser (Fakultät für Psychologie, Psychologische Methodenlehre, Ruhr-Universität Bochum).

Organisiert wurde der Workshop in Zusammenarbeit zwischen dem Interdisziplinären Zentrum für empirische Lehrer*innen- und Unterrichtsforschung (IZeF) und der Graduiertenschule der Humanwissenschaftlichen Fakultät.

Prof. Dr. Nils Buchholtz led the Workshop in which provided an introduction in the Mixed-Methods and its practical use. Furthermore the participants learned about the Point of Integration and the Joint Displays methods and their use in todays research. Finally the participants hat the opportunity to ask and discuss questions about their own research projekts. The Workshop was organized by the IZeF and the Graduates-School of the fakulty of human science.

During this Workshop the participants received a introduction into Multilevel-Modeling as well as its application in the statistical softwares Mplus and R. Furthermore the participants had the opportunity to discuss their own Research questions and to receive feedback on their work in Mplus and R. The Workshop was held by Dr. Malte Jansen and organized in cooperation between the IZeF and the Graduate school of the faculty of human sciences.

The two-day workshop on "Structural Equation Models: Confirmatory Factor Analysis, Path Analysis, and Longitudinal Models", led by Prof. Dr. Christian Rietz (Heidelberg University of Education), was aimed at doctoral students in the "advanced early stages" of their doctoral studies. On the one hand, the participants received guidance for deciding whether they wanted to use the methods in question for their own research, and on the other hand, they received advice or assistance for working on their own research data. The workshop was organized in cooperation between the IZeF and the Graduate School of Humpf.

The workshop, led by Dr. Rainer Leonhart (University of Freiburg), was aimed at advanced beginners and taught the theoretical basics of structural equation models as well as practical knowledge acquired with the AMOS and MPlus programs.

IRT Workshop (Introduction)
In this introductory workshop the basics of IRT scaling including the Rasch model were discussed. One focus was on the direct application of what had been learned to the participants' own data sets.

Multilevel Analyses
The English-language workshop dealt with the problem that data in empirical educational research often arise in the form of hierarchically clustered groups, such as female pupils in different school classes at different schools. Prof. Dr. Fred Hasselmann of the University of Nijmegen taught different analysis methods such as multi-level models for repeat measurements and multivariate models.

IRT Scaling I and II
Similar to the workshop in February 2015, also led by Dr. Andreas Seifert, basic principles such as the partial credit model, the interpretation of output graphics, the interaction of the properties in the Rasch model and the Rasch model in longitudinal analyses were discussed. Building on this, a second workshop was held, in particular to analyse and discuss the participants' own data.

Item-Response-Theory (IRT): Introduction and Scaling Techniques
This method workshop aimed at a general introduction to IRT scaling and the Rasch model. In addition, joint calculations with sample files were carried out. Dr. Andreas Seifert from the University of Paderborn participated as a speaker.
