[The contribution of Open Science to the quality of educational research]

The starting point of this paper are the discussions of the robustness of empirical findings in related disciplines, namely social psychology, which culminated in the so-called "replication crisis". These discussions about replication and "questionable research practices" have only started to reach the educational sciences. At the same time, parts of the educational sciences are prone to the same problems as related disciplines. Therefore, it may only be a matter of time before these controversies also arise in the educational sciences. Against this backdrop, we argue how Open Science can contribute to increasing the robustness of educational sciences' findings. In particular, we suggest three Open Science practices: Pre-registration, Open Materials and Open Data. We present these practices and examine how researchers can implement these Open Science practices in the educational sciences. We discuss the specific conditions of the educational sciences in comparison to related disciplines and address the limitations and particularities of the educational sciences. We conclude with a plea for transparency.
