At present, there are relatively few international studies that reflect research in religious didactics from a metatheoretical perspective. Against this background, the fundamental question of this contribution is whether there are research designs that are typical for research in religious didactics. For this purpose, research was conducted for a later Delphi study; its development, results, and open questions are presented below. The study does not only produce certain findings and problem indications with regard to research designs of religious didactics, but perhaps even in a general model for religious-didactic research. We regard the current status of this project as an interim result, which shall be examined in a subsequent round, taking into account the international context.
