AI systems are revolutionizing the way we absorb information and process knowledge. Examples include voice assistants such as Siri and Alexa, learning platforms such as Duolingo, a wide range of commercial AI chatbots, and, in a university context, RWTHgpt and Ritchy at RWTH Aachen University. These technologies use machine learning to provide personalized learning experiences tailored to the needs of individual users.
But the key question is: How can AI be used in a way that truly improves learning and is not counterproductive?

For over 14 years, it has provided a platform for administrators and IT enthusiasts to exchange information on current university-related IT topics throughout RWTH. The round table is organised by a dedicated team of five from various institutions and the IT Center.

In this series, the IT Center’s UX team reports on its work. When developing interactive systems such as websites and apps, not only HTML, CSS and JavaScript play a decisive role, but also usability and user experience. Put simply, this refers to the question of whether a system supports its users in achieving their goals effectively, efficiently and satisfactorily and what perceptions and reactions result from using a system.
At the IT Center, we also focus on the usability and user experience of our systems. User tests such as the annual satisfaction survey on the RWTHapp are a key tool that we use for this. You can find this year’s results here.

On September 9, 2025, the root certificate for the RADIUS server of eduroam and RWTH-institutes will be changed to the new DFN Community Root CA 2022 as part of a regular security measure. From this point on, only the new certificate will work – it will no longer be possible to use the old one. To ensure that you remain connected securely and without problems after September 9, you should update your WLAN configuration in good time.
