Intruduction:
Education and training in higher education is a big challenge nowadays for both students and teachers. Due to the impact of the development of modern technologies and new trends in education, it is also necessary to test new approaches to learning at our university and faculty. That is why we have decided to engage in projects within the framework of scientific research activities, the results of which we will subsequently transfer to teaching. In this article we present our initial findings and especially the conclusions from our testing in Virtual Scenario Based Training using Virtual realiyt (VR), Augmented realiyt (AR), Mixed realiyt (MR) and the programs we use in teaching. The basic purpose of this paper is to compare the testing of new technologies within VSBT in teaching students in OSH and crisis management courses and try to find the most appropriate tools to make OSH and crisis management teaching more effective.

Methods:
Comparison, testing, statistical evaluation, simulations, analysis Results Testing 10 scenarios with students in OSH and Work environment subjects showed that students were more interested in this way of teaching than AR and MR. The added value was in learning simple tasks and finding errors in operations from a safety perspective is valuable here. Testing of the FightARs app highlighted the need to combine scenarios created for Hololens 2 with 2D videos and visual material created in the LMS. Scenarios for a hazardous substance spill and an electric car crash were tested. In subjects focused on situational awareness is this toll really usable and valuable. The 2D scenarios proved to be the most effective in our testing when testing longer scenarios that required the need for dynamic decision making. Scenarios were also combined using VR and MR glasses during the excercise.

Conclusion:
Not all tools make the grade for every learning session and therefore the process is very often trial and error. However, we have first results that have created a pre-requisite for further development. The tested scenarios are useful in teaching in terms of training situational analysis and dynamic decision making.
