The content of this paper is a reflection on the possibilities of how students and teachers of CTU in Prague can utilize AI in learning and teaching without violating ethical code. The aim is to find out to what extent university ethical codes and guidelines offer clear and reliable support for the teachers’ and students’ educational activities. We employed a mixed methods approach in the study, analyzing documents provided by a technical university administration related to ethical rules for using AI in the first phase, and conducting interviews with teachers from 9 faculties in the second phase. Results reveal that the CTU has declared ethical codes defining the activities and areas where students are allowed/partially allowed or not allowed to use AI. The decision to allow the use depends on the scope of each specific activity and area. Framework rules of use and misuse of AI for educational purposes are set out for teachers accordingly. Not all the university teachers are fully familiar with the potentials of AI in the studies while all have concerns of ethical aspects its misuses. Teachers think it is indispensable to define institutional guidelines to manage the ethical issues of AI. They also welcome future training opportunities to effectively implement and manage the use of AI in technical teaching and learning.
