Open Science

At the Chair in Empirical Educational Research we support the Open Science movement. Our aim is a maximum of credibility and validity of the results. Thus, we ensure that every study can be replicated and the data reanalyzed and synthesized by any researcher.

Therefore, in every research project and in all publications since 2017, we committed ourselves to the following basic principles:

Preregistration: Whenever possible, we register our research projects prior to data collection using reliable Open Science platforms such as https://osf.io/. We provide the link to the preregistration in every publication.

Open Methodology: We document the methods and procedures used so that every person with expertise can understand them and can reproduce the findings.

FAIR data: As recommended by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG), we make all data leading to our papers’ conclusions publicly accessible upon publication (either on the journal’s website or on Open Science Platforms), linking manuscript and data via persistent identifiers. In principle, we provide the primary data, the full data sheet along with a codebook explaining our variables and the reproducible Code (i.e. R scripts, syntax commands), including transformations performed on raw data prior to analysis. Of course, all personal identifying information is removed from shared data to protect the confidentiality of all research participants.

Open materials and Open source: All materials (if not copyrighted by a third party) are provided at the respective repository. Whenever possible, we use open source software solutions (i.e. R, JASP) for data analysis.

Open-access endorsement: We routinely prefer open-access publication to ensure that our research is accessible free of charge to other scientists and the public. If that is not possible, we provide pre/postprints (according to the regulations of the journals) on our website or upon request in according to the directives provided on Sherpa Romero.

Furthermore, we integrate Open Science principles into teaching and encourage our students and young scientists at the department to comply to them.

Author contributions: Since 2021, we indicate on each publication the authors’ contribution roles according to the Contributor Roles Taxonomy (CrediT).
