[Holistic school development in the implementation of educational technologies in times of digital transformation-a case study on the self-evaluation tool SELFIE].

The digital transformation is increasingly shaping the education system and school development. In this context, the implementation of educational technologies in schools and classrooms plays a critical role. In systemic terms, this is a school development task that involves sustainable and continuous changes at all levels of school and poses (new) challenges for the groups of school stakeholders. In addition to the development of organizational, teaching and personnel dimensions, this also requires changes in the technology and cooperation mechanisms specific to the needs of individual schools. By means of a case study, this study analyzes the implementation and execution of the self-evaluation tool SELFIE at a school using a multimethodological approach. The results of the self-evaluation ( n  = 265) as well as findings from multi-episodic interviews ( n  = 11) with various school actors are presented and interpreted in consideration of the school development dimensions. In the discussion, SELFIE is first critically reflected as an eligible digital tool for self-evaluation in relation to the implementation of educational technologies. Second, its effects on the school development dimensions are discussed. Finally, an outlook on the potentials as well as critical challenges of SELFIE with regard to school development for research and practice is given.
