Success stories

City Solingen

Situation: After the coronavirus pandemic the public transport could not be sufficiently adapted to the new health regulations, which meant that not all of the students were able to get to school.

Goal: A hybrid concept which enables half of the class to stay at home and the other half to come to school on an alternative base. This minimises the risk of infection.

Execution: Sdui has been chosen by the school authorities, as a uniform solution to support all schools with presential and remote lessons. We analyse the elements required to implement hybrid lessons and made integration of existing softwares possible.

Result: The schools were given Sdui: a flexible and GDPR conform platform as a basis, in combination with other solutions. Now the change between face-to-face and remote lessons is truly easy and works without any problems. To this day, the model in Solingen is a perfect example for successful hybrid lessons.

Situation: In February 2020 a hurricane lead to a wind speed of up to 200 kph. This lead to the majority of lessons in school and activities in daycare centres being cancelled. Parents had to be informed in an efficient and quick manner.

Goal: Ensure that all the important information reaches the relevant people so that everyone can stay safe.

Execution: The school management informed everyone about the regulations in relation to the storm for the next day using the Sdui app. The read receipt enabled them to see who had already been informed. The parents were then able to decide, whether they would send their children to school. If not, they could confirm their absence via telephone or using the Sdui app.

Result: Sdui enabled the school management to ensure the safety of the pupils and ensure that everyone is informed. The app also meant that the communication was more efficient and consistent.

Why did we develop Sdui?

Sdui Team
The Sdui team, summer 2020

Sdui was created to build a solution to real problems. We can see where schools are today and we understand where schools should be in the future. Our team is made of ex-students and teachers and we have many more individuals on board, that can help us identify what problems schools face on a daily basis. Every day we work hard to further adapt and expand our platform to the needs of teachers, students and parents, to be able to make their lives easier. If they change, we change with them.

The real challenge of the digital transformation is that it works differently for every school and for every person. We are aware that digitalisation is not a straightforward process, as everyone has their own wishes, needs and demands. We listen to these in order to be able to adjust the app to their needs, which enables us to create a personalised platform. The goal of Sdui is to create a platform that acts both as a basis and a tool: a solution in which all relevant people come together in a safe space and where everyone finds the features and support that make their personal everyday life easier. We call this space the “Digital School”.

Our vision of a digital school

Our vision of a successful digital school is based on the great exchange with schools and daycare centres. Our aim is not a replacement for face-to-face classes at school. Our focus is to support them and to ensure that lessons can happen despite of various crisis. We want to create an environment similar to the one at school, with all the members coming together in one digital place. We want to facilitate the exchange of information by creating ways of communication by text, call and video call for all the members of the school. Our dream is to create schools, where nothing has to be looked for or figured out. We want all the information to be easy to find. The features and tools within the app are created to meet the needs of the school: everything you need is there and nothing else but this. The digital school is secure. Not only because it is GDPR conform but also because it protects students from cyber bullying and teachers from stress. And in case that face-to-face learning is not possible, you can still teach digitally.

This is our vision of a digital school. This is what Sdui creates.
