Success stories

Dirk Wagner, Head of Digital for the City of Solingen

City of Solingen

Situation: In order to resume classroom teaching during the Covid-19 pandemic, it was not possible to adequately ensure the health of the large number of commuting students in public transport.

Goal: A hybrid school concept with which half of all classes can be taught alternately at home or in person in order to reduce the risk of infection.

Implementation: Sdui was used by the executing agency as a uniform solution in all schools to provide support in face-to-face and distance learning. We analyzed which components were needed to implement the hybrid concept and created interfaces for existing systems.

Result: The schools received a flexible, GDPR-compliant platform as a basis for combining with other solutions. Switching between face-to-face and distance learning on the fly is now easily possible. The Solingen model is now considered a successful example of hybrid teaching.

Situation: In February 2020, hurricane “Sabine” caused wind peaks of up to 200km / h. Schools and daycare had to be largely closed and parents had to be informed.

Goal: Ensure that the important information reaches all relevant people at short notice and that everyone is safe.

Implementation: The evening before, the headmaster communicated the storm regulations via app in order to really reach everyone. A read receipt showed him who had already been informed. The parents decided for themselves whether they wanted to leave their children at home and could deregister them by phone or Sdui.

Result: Thanks to Sdui, the headmaster was able to take care of the
Ensure security and clarification of all relevant persons, avoid overloading the telephone system and solve a crisis situation confidently

Why did we develop Sdui?

The Sdui team in summer 2020

Sdui was born out of a desire to provide solutions to real problems. We see schools where they are today and understand where they should be tomorrow. As former students with many teachers in the company and environment, we know firsthand what problems schools are confronted with on a daily basis. We are working hard to adapt our platform to the needs of teachers, students and parents in such a way that everyone's everyday life is made a lot easier. Change yourself, we change with you.

The challenge of digital change is that it means something different for every institution, every school and every person. Everyone has different wishes, views and experiences. That is why we are also aware that digitization is not a linear path: We respond to personal needs, adjust the screws if necessary, and thus want to create an environment with real added value. The goal of Sdui is a platform that is both a foundation and a tool: a solution in which all relevant people come together in a safe space and everyone can find the functions and support that make their everyday lives easier. We call this room the “digital school”.

Our vision of a digital school

Our vision of a successful digital school is based on a large number of impressions from our direct exchange with schools. It should not replace the school in attendance, but complement, empower and support in crisis situations. Just as all relevant participants are in one environment in the school building, they should also be able to come together digitally: a flowing exchange in oral, written and visual form with everyone, including legal guardians. We dream of a school in which there is no longer any need to look for and puzzle over how something works. Functions and tools meet the needs of school participants: there is nothing missing and nothing is superfluous. The digital school is safe: GDPR compliant, yes, but it also protects students from bullying and teachers from stress. And if face-to-face teaching is not possible, it should be able to replace this 1: 1.
This is our vision of a digital school. That's what Sdui creates.
