Opis: The aim of the Master’s thesis was to evaluate the current and potential applications of virtual reality technology in chemistry and chemical engineering, as well as to evaluate the use of virtual reality for educational purposes. First, we made an overview of the numerous applications of the virtual reality technology with a specific focus on its current use in the chemistry and chemical engineering fields, including research and educational environments as well as industrial applications. It was found that the use of virtual reality technology is growing in all areas, with training, remote collaboration, and interactive learning being the most prominent fields. To assess the effectiveness of virtual reality as an educational tool, we performed a study with second year students of Chemistry and Chemical Engineering programs at the Faculty of Chemistry and Chemical Engineering, University of Maribor. Students were divided into two groups, one undertaking a training on the proper use of fume hoods in virtual reality and the other group performing the same training in a real chemical laboratory. Students from both groups took a knowledge evaluation test and a personal experience survey after the training. The test results have shown that virtual reality can be just as effective or potentially even more effective than conventional training in the chemical laboratory. The average score of the virtual reality group was 2.5% higher than that of the group performing conventional training in a chemical laboratory, although we did not confirm a statistically significant difference between the scores. We also prepared a personal experience survey to evaluate the students’ personal experience and interest in using virtual reality as an educational tool. It was observed that there is a lot of enthusiasm from the students for the use of virtual reality technology and that the group performing the training in virtual reality reported a significantly better subjective experience scores, and due to fewer reported distractions remained more focused on the training content compared to the group that underwent the training in a real chemical laboratory. The results of the Master’s thesis suggest that virtual reality presents an effective alternative to traditional live training methods. Future research should be conducted with larger groups focusing especially on the long-term retention of the acquired knowledge and on the application in real-world scenarios, such as laboratory exercises, device training, and safety procedures training, to fully reveal the potential of virtual reality for educational purposes.

Opis: Traditional teaching does not often allow very active involvement of pupils in class. In chemistry and natural sciences in general experimental and laboratory work is one of the most effective methods for acquiring knowledge. Experimental work can also be exercised using virtual world. Virtual laboratory offers some important advantages. Understanding chemistry involves the ability of cognitive comprehension on three levels: the macroscopic level, the symbolic level and the level of particles where the virtual laboratory can be an effective tool. On this basis a didactic experiment was performed in order to verify the effectiveness of virtual laboratory from pupils' knowledge point of view. The experiment involved seventh grade pupils (N = 38). Furthermore, we tried to answer the question whether the learning results of pupils, according to the experimental design of classes using a virtual laboratory, are better than results gained through teaching classical science classes without visualization tools. The research of the didactic experiment carried out on a relatively small, pilot sample of pupils has shown that acquiring knowledge is more effective when using the virtual laboratory instead of classical teaching (in the case when classical approach does not include visualization elements crucial for learning and understanding chemistry).
