Teachers' role in digitalizing education: an umbrella review.

As teachers are central to digitalizing education, we summarize 40 years of research on their role in that process within a systematic umbrella review that includes 23 systematic reviews with a total of 1062 primary studies focusing technology integration and aspects of digital literacy. Our findings highlight the international acceptance of the TPACK framework as well as the need for a clear concept of digital literacy. It is unique that we identify and discuss parallels in developing teachers' digital literacy and integrating digital technologies in the teaching profession as well as barriers to those goals.

[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.

The unique effects of Covid-19 - A qualitative study of the factors that influence teachers' acceptance and usage of digital tools.

The objective of this study is to examine the factors that influence teachers' acceptance of digital tools for undertaking distance teaching during the Covid-19 pandemic. Based on the variables of the technology acceptance model, we have conducted interviews with 15 secondary school teachers with varying degrees of professional experiences and combinations of subjects, from the federal state of Baden-Wuerttemberg in Germany and analyzed the same. The results indicate that, other than user motivation, three areas, namely "regulations and specifications," "technological infrastructure," and "heterogeneity of students and teachers," affect the adoption of digital tools.
