At a time when computers are represented in every more developed house in the 21st century, the question of using computers for educational purposes arises. It is the computer that becomes the main link and bridge between learning and play. It is this bridge that was built from connecting today's way of learning and the future in which, I believe, the question of the use of computers in education is increasingly arising. The use of computer games for educational purposes raises the question of what are the new ways of teaching, practicing, transferring knowledge and skills nowadays. In this way, we try to attract children to learning in the most interesting and unusual way possible. Greater interactivity of children during individual or group work shows how, for children, the computer can be used for educational purposes. Today, there are various portals and sites that provide free access to educational and computer games. In almost every area, there is at least one game that can and should awaken in children the desire to play and thus the desire for new ways of learning. In children, they most often encourage activity, thinking, memory and speed. In order to investigate the advantages and disadvantages of using educational computer games in the teaching process, a study was conducted whose goal was to investigate the experience of teachers, related to their perception of the advantages and disadvantages of using computer games for educational purposes. The results of the empirical research are presented in this thesis.
